Virtual Chassis Technology The EX4650 supports Juniper Networks unique Virtual Chassis technology, which enables up to four interconnected switches to operate as a single, logical device with a single IP address. Virtual Chassis technology allows enterprises to separate physical topology from logical groupings of endpoints, ensuring more efficient resource utilization. When deployed in a Virtual Chassis configuration, EX4650 switches can be connected using up to four of the 40GbE or 100GbE ports in link aggregation groups (LAGs) across 40GbE/1000GbE ports, providing an aggregate backplane capacity of up to 1.04 Tbps.






Campus Fabric Technology Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers. Juniper’s campus fabrics support the following validated architectures:

EVPN Multihoming (Collapsed Core/Distribution): A pair of interconnected EX4650 switches can be deployed to provide EVPN multihoming (ESI-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.

Campus Fabric or Core Distribution: A pair of interconnected EX4650 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the EX4650:

• Centrally routed bridging overlay: Integrated Routing and Bridging (IRB) interface placed at a central location in the fabric (in this case, a core device)

• Edge routed bridging overlay: IRB interface placed at the edge of the fabric (in this case, a distribution device)

Campus Fabric IP Clos: The Campus Fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, EX4650 acts as an IP fabric distribution switch






Managing AI-Driven Campus Fabric with the Juniper Mist Cloud Juniper Mist Wired Assurance brings cloud management and Mist AI to campus fabric. It sets a new standard moving away from traditional network management towards AI-driven operations, while delivering better experiences to connected devices. The Juniper Mist cloud streamlines deployment and management of campus fabric architectures by allowing:

• Automated deployment and zero touch deployment

• Anomaly detection

• Root cause analysis



Enterprise On-Premises Server Connectivity - Data centers are demanding more high-speed, low-latency, storage- and I/O-converged networking solutions to maximize the performance of their physical servers, virtual servers, and storage. The EX4650 addresses these needs with low-latency, lossless, high-density 10GbE and 25GbE interfaces, as well as 100GbE uplinks to the core network. Furthermore, the EX4650 offers EVPN-VXLAN L2 and L3 gateway support, making it an ideal solution for overlay deployments in the enterprise on-premises data center.



The EX4650 also offers flexible airflow options, enabling them to support back-to-front and front-to-back cooling to ensure consistency with server designs for hot-aisle or cold-aisle deployments. Support for tri-speed 1GbE/10GbE/25GbE make the EX4650 ideal for enterprise server access; 48 ports of native 10GbE/25GbE for server connectivity and up to eight 40GbE or 100GbE ports for uplink connectivity provide very low oversubscription of 1.5:1 from access to aggregation. Each 40GbE port can be broken out into four 10GbE ports, providing additional options for server connectivity.

The EX4650 operates in both cut-through and store-and-forward modes, delivering sustained wire-speed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in both modes. With features such as EVPN multihoming (ESI-LAG) and MC-LAG, the EX4650 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch.




Wired Service Level Expectation The Wired Assurance feature provides operational visibility into the wired experience with service-level expectations (SLEs) for EX Series Switches. Pre- and post-connection performance metrics help you monitor successful connects and switch health throughout the system, using Mist AI to measure and manage networks and simplify troubleshooting.




Automation The EX4650 supports a number of network automation and plug-and-play features, including ZTP and event scripts, automatic rollback, and Python scripting.




Flexible Forwarding Table The EX4650 includes a Unified Forwarding Table (UFT), which allows the hardware table to be divided into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the EX4650 supports up to 288,000 MAC addresses; in L3 mode, the table can support up to 168,000 host entries; in LPM mode, the table can support up to 360,000 prefixes. Junos OS provides configurable options through a CLI to optimize the EX4650 for various deployment scenarios.




Intelligent Buffer Management The EX4650 features a total of 32 MB of shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the EX4650 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.




MPLS A broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP, support standards-based network segmentation and virtualization, allowing the EX4650 to be deployed as a low-latency MPLS label-switching router (LSR).




VXLAN Overlays The EX4650 is capable of both L2 and L3 VXLAN gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN for programming the overlays, which can operate without a controller or be orchestrated with an SDN controller like OpenContrail.




Junos OS Running Junos OS, which features the most advanced and robust routing capabilities in the industry, the EX4650 supports RIP and OSPF for both IPv4 and IPv6, as well as advanced routing capabilities such as IS-IS and BGP. With additional capabilities such as 64-way equal-cost multipath (ECMP) and BGP add path, the EX4650 is an ideal building block for deploying the most robust L3 underlay for SDN.




EVPN-VXLAN Many proprietary campus architectures are built on traditional L2 Ethernet-based architectures that address the desire to eliminate Spanning Tree Protocol (STP). With the increase of IoT devices in the enterprise, these networks will be expected to scale rapidly without adding complexity and resources. Some of these IoT devices, however, have limited networking capabilities and require L2 adjacency across buildings or campuses. To address this problem, traditional solutions extend VLANs across buildings and campuses using data plane flood-and-learn. Unfortunately, this solution is inefficient and difficult to manage. The increasing number of network endpoints, coupled with rapidly changing business needs, demands an open, standards-based network that is simple, scalable, and programmable across both the campus and the data center.

Modern enterprise networks need a campus architecture that decouples the overlay network from the underlay network with technologies such as VXLAN, which enables network administrators to create logical L2 networks across different L3 networks. The EX4650 satisfies these requirements by supporting EVPN-VXLAN L2 and L3 gateway capabilities, providing the following benefits:

Improved network and host mobility efficiency

• Control plane MAC learning to reduce unknown-unicast flooding

• Reduced Address Resolution Protocol (ARP) flooding due to MAC-to-IP binding in control plane

• Multipath traffic over multiple core switches (VXLAN entropy)

• Multipath traffic to active/active dual-homed access layer switches

Fast convergence

• Faster reconvergence when linked to dual-homed access switches fail (aliasing)

• Faster reconvergence when endpoints move

Scalability

• Scalable BGP-based control plane

• Seamless expansion of the core, distribution, and access layers as business needs grow

• Seamless expansion of campuses as business needs grow

Flexibility

• Easy integration with L3 and L2 VPNs

• BGP-based control plane functionality that allows application of fine-grained policies

Nonproprietary

• Standards-based protocols that support multivendor core, distribution, and access layers




Junos Telemetry Interface The EX4650 supports Junos Telemetry Interface (JTI), a modern telemetry streaming tool designed for performance monitoring in enterprise networks. Streaming data to a performance management system enables network administrators to measure trends in link and node utilization, and troubleshoot such issues as network congestion in real time. JTI delivers the following features:

• Application visibility and performance management by provisioning sensors to collect and stream data and analyze application and workload flow paths through the network

• Capacity planning and optimization by proactively detecting hotspots and monitoring latency and microbursts

• Troubleshooting and root cause analysis via high-frequency monitoring

Virtual Chassis Technology The EX4650 supports Juniper Networks unique Virtual Chassis technology, which enables up to four interconnected switches to operate as a single, logical device with a single IP address. Virtual Chassis technology allows enterprises to separate physical topology from logical groupings of endpoints, ensuring more efficient resource utilization. When deployed in a Virtual Chassis configuration, EX4650 switches can be connected using up to four of the 40GbE or 100GbE ports in link aggregation groups (LAGs) across 40GbE/1000GbE ports, providing an aggregate backplane capacity of up to 1.04 Tbps.






Campus Fabric Technology Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers. Juniper’s campus fabrics support the following validated architectures:

EVPN Multihoming (Collapsed Core/Distribution): A pair of interconnected EX4650 switches can be deployed to provide EVPN multihoming (ESI-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.

Campus Fabric or Core Distribution: A pair of interconnected EX4650 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the EX4650:

• Centrally routed bridging overlay: Integrated Routing and Bridging (IRB) interface placed at a central location in the fabric (in this case, a core device)

• Edge routed bridging overlay: IRB interface placed at the edge of the fabric (in this case, a distribution device)

Campus Fabric IP Clos: The Campus Fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, EX4650 acts as an IP fabric distribution switch

Enterprise On-Premises Server Connectivity - Data centers are demanding more high-speed, low-latency, storage- and I/O-converged networking solutions to maximize the performance of their physical servers, virtual servers, and storage. The EX4650 addresses these needs with low-latency, lossless, high-density 10GbE and 25GbE interfaces, as well as 100GbE uplinks to the core network. Furthermore, the EX4650 offers EVPN-VXLAN L2 and L3 gateway support, making it an ideal solution for overlay deployments in the enterprise on-premises data center.



The EX4650 also offers flexible airflow options, enabling them to support back-to-front and front-to-back cooling to ensure consistency with server designs for hot-aisle or cold-aisle deployments. Support for tri-speed 1GbE/10GbE/25GbE make the EX4650 ideal for enterprise server access; 48 ports of native 10GbE/25GbE for server connectivity and up to eight 40GbE or 100GbE ports for uplink connectivity provide very low oversubscription of 1.5:1 from access to aggregation. Each 40GbE port can be broken out into four 10GbE ports, providing additional options for server connectivity.

The EX4650 operates in both cut-through and store-and-forward modes, delivering sustained wire-speed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in both modes. With features such as EVPN multihoming (ESI-LAG) and MC-LAG, the EX4650 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch.




Wired Service Level Expectation The Wired Assurance feature provides operational visibility into the wired experience with service-level expectations (SLEs) for EX Series Switches. Pre- and post-connection performance metrics help you monitor successful connects and switch health throughout the system, using Mist AI to measure and manage networks and simplify troubleshooting.




Automation The EX4650 supports a number of network automation and plug-and-play features, including ZTP and event scripts, automatic rollback, and Python scripting.




Flexible Forwarding Table The EX4650 includes a Unified Forwarding Table (UFT), which allows the hardware table to be divided into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the EX4650 supports up to 288,000 MAC addresses; in L3 mode, the table can support up to 168,000 host entries; in LPM mode, the table can support up to 360,000 prefixes. Junos OS provides configurable options through a CLI to optimize the EX4650 for various deployment scenarios.




Intelligent Buffer Management The EX4650 features a total of 32 MB of shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the EX4650 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.




MPLS A broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP, support standards-based network segmentation and virtualization, allowing the EX4650 to be deployed as a low-latency MPLS label-switching router (LSR).




VXLAN Overlays The EX4650 is capable of both L2 and L3 VXLAN gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN for programming the overlays, which can operate without a controller or be orchestrated with an SDN controller like OpenContrail.




Junos OS Running Junos OS, which features the most advanced and robust routing capabilities in the industry, the EX4650 supports RIP and OSPF for both IPv4 and IPv6, as well as advanced routing capabilities such as IS-IS and BGP. With additional capabilities such as 64-way equal-cost multipath (ECMP) and BGP add path, the EX4650 is an ideal building block for deploying the most robust L3 underlay for SDN.




EVPN-VXLAN Many proprietary campus architectures are built on traditional L2 Ethernet-based architectures that address the desire to eliminate Spanning Tree Protocol (STP). With the increase of IoT devices in the enterprise, these networks will be expected to scale rapidly without adding complexity and resources. Some of these IoT devices, however, have limited networking capabilities and require L2 adjacency across buildings or campuses. To address this problem, traditional solutions extend VLANs across buildings and campuses using data plane flood-and-learn. Unfortunately, this solution is inefficient and difficult to manage. The increasing number of network endpoints, coupled with rapidly changing business needs, demands an open, standards-based network that is simple, scalable, and programmable across both the campus and the data center.

Modern enterprise networks need a campus architecture that decouples the overlay network from the underlay network with technologies such as VXLAN, which enables network administrators to create logical L2 networks across different L3 networks. The EX4650 satisfies these requirements by supporting EVPN-VXLAN L2 and L3 gateway capabilities, providing the following benefits:

Improved network and host mobility efficiency

• Control plane MAC learning to reduce unknown-unicast flooding

• Reduced Address Resolution Protocol (ARP) flooding due to MAC-to-IP binding in control plane

• Multipath traffic over multiple core switches (VXLAN entropy)

• Multipath traffic to active/active dual-homed access layer switches

Fast convergence

• Faster reconvergence when linked to dual-homed access switches fail (aliasing)

• Faster reconvergence when endpoints move

Scalability

• Scalable BGP-based control plane

• Seamless expansion of the core, distribution, and access layers as business needs grow

• Seamless expansion of campuses as business needs grow

Flexibility

• Easy integration with L3 and L2 VPNs

• BGP-based control plane functionality that allows application of fine-grained policies

Nonproprietary

• Standards-based protocols that support multivendor core, distribution, and access layers




Junos Telemetry Interface The EX4650 supports Junos Telemetry Interface (JTI), a modern telemetry streaming tool designed for performance monitoring in enterprise networks. Streaming data to a performance management system enables network administrators to measure trends in link and node utilization, and troubleshoot such issues as network congestion in real time. JTI delivers the following features:

• Application visibility and performance management by provisioning sensors to collect and stream data and analyze application and workload flow paths through the network

• Capacity planning and optimization by proactively detecting hotspots and monitoring latency and microbursts

• Troubleshooting and root cause analysis via high-frequency monitoring

Virtual Chassis Technology The EX4650 supports Juniper Networks unique Virtual Chassis technology, which enables up to four interconnected switches to operate as a single, logical device with a single IP address. Virtual Chassis technology allows enterprises to separate physical topology from logical groupings of endpoints, ensuring more efficient resource utilization. When deployed in a Virtual Chassis configuration, EX4650 switches can be connected using up to four of the 40GbE or 100GbE ports in link aggregation groups (LAGs) across 40GbE/1000GbE ports, providing an aggregate backplane capacity of up to 1.04 Tbps.






Campus Fabric Technology Juniper Networks campus fabrics provide a single, standards-based Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) solution that can be deployed in any campus, whether a two-tier network with a collapsed core distribution or a campus-wide system that involves multiple buildings with separate distribution and core layers. Juniper’s campus fabrics support the following validated architectures:

EVPN Multihoming (Collapsed Core/Distribution): A pair of interconnected EX4650 switches can be deployed to provide EVPN multihoming (ESI-LAG) in a collapsed core/distribution configuration. This eliminates the need for Spanning Tree Protocol (STP) across the campus network by providing multihoming capabilities from the access to the distribution layer, while distribution to core is an L3 IP fabric. ESI-LAG also supports horizontal scaling with more than two devices in the distribution layer and can extend EVPN to the core.

Campus Fabric or Core Distribution: A pair of interconnected EX4650 switches can provide EVPN L2 and L3 VXLAN gateway support. This eliminates the need for STP across the campus network by providing a multihoming capability from the access to the distribution layer, while distribution to the core is an L3 IP fabric using EVPN technology. The IP fabric can also extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across buildings. An IP Clos network between the distribution and the core layers can exist in two modes, both of which are supported by the EX4650:

• Centrally routed bridging overlay: Integrated Routing and Bridging (IRB) interface placed at a central location in the fabric (in this case, a core device)

• Edge routed bridging overlay: IRB interface placed at the edge of the fabric (in this case, a distribution device)

Campus Fabric IP Clos: The Campus Fabric IP Clos architecture pushes VXLAN Layer 2/3 gateway functionality to the access layer. In this architecture, EX4650 acts as an IP fabric distribution switch

Enterprise On-Premises Server Connectivity - Data centers are demanding more high-speed, low-latency, storage- and I/O-converged networking solutions to maximize the performance of their physical servers, virtual servers, and storage. The EX4650 addresses these needs with low-latency, lossless, high-density 10GbE and 25GbE interfaces, as well as 100GbE uplinks to the core network. Furthermore, the EX4650 offers EVPN-VXLAN L2 and L3 gateway support, making it an ideal solution for overlay deployments in the enterprise on-premises data center.



The EX4650 also offers flexible airflow options, enabling them to support back-to-front and front-to-back cooling to ensure consistency with server designs for hot-aisle or cold-aisle deployments. Support for tri-speed 1GbE/10GbE/25GbE make the EX4650 ideal for enterprise server access; 48 ports of native 10GbE/25GbE for server connectivity and up to eight 40GbE or 100GbE ports for uplink connectivity provide very low oversubscription of 1.5:1 from access to aggregation. Each 40GbE port can be broken out into four 10GbE ports, providing additional options for server connectivity.

The EX4650 operates in both cut-through and store-and-forward modes, delivering sustained wire-speed switching with sub-microsecond latency and low jitter for any packet size (including jumbo frames) in both modes. With features such as EVPN multihoming (ESI-LAG) and MC-LAG, the EX4650 supports active/active server dual homing and can utilize full bisectional bandwidth from server to switch.




Wired Service Level Expectation The Wired Assurance feature provides operational visibility into the wired experience with service-level expectations (SLEs) for EX Series Switches. Pre- and post-connection performance metrics help you monitor successful connects and switch health throughout the system, using Mist AI to measure and manage networks and simplify troubleshooting.




Automation The EX4650 supports a number of network automation and plug-and-play features, including ZTP and event scripts, automatic rollback, and Python scripting.




Flexible Forwarding Table The EX4650 includes a Unified Forwarding Table (UFT), which allows the hardware table to be divided into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the EX4650 supports up to 288,000 MAC addresses; in L3 mode, the table can support up to 168,000 host entries; in LPM mode, the table can support up to 360,000 prefixes. Junos OS provides configurable options through a CLI to optimize the EX4650 for various deployment scenarios.




Intelligent Buffer Management The EX4650 features a total of 32 MB of shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the EX4650 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.




MPLS A broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP, support standards-based network segmentation and virtualization, allowing the EX4650 to be deployed as a low-latency MPLS label-switching router (LSR).




VXLAN Overlays The EX4650 is capable of both L2 and L3 VXLAN gateway services. Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN for programming the overlays, which can operate without a controller or be orchestrated with an SDN controller like OpenContrail.




Junos OS Running Junos OS, which features the most advanced and robust routing capabilities in the industry, the EX4650 supports RIP and OSPF for both IPv4 and IPv6, as well as advanced routing capabilities such as IS-IS and BGP. With additional capabilities such as 64-way equal-cost multipath (ECMP) and BGP add path, the EX4650 is an ideal building block for deploying the most robust L3 underlay for SDN.




EVPN-VXLAN Many proprietary campus architectures are built on traditional L2 Ethernet-based architectures that address the desire to eliminate Spanning Tree Protocol (STP). With the increase of IoT devices in the enterprise, these networks will be expected to scale rapidly without adding complexity and resources. Some of these IoT devices, however, have limited networking capabilities and require L2 adjacency across buildings or campuses. To address this problem, traditional solutions extend VLANs across buildings and campuses using data plane flood-and-learn. Unfortunately, this solution is inefficient and difficult to manage. The increasing number of network endpoints, coupled with rapidly changing business needs, demands an open, standards-based network that is simple, scalable, and programmable across both the campus and the data center.

Modern enterprise networks need a campus architecture that decouples the overlay network from the underlay network with technologies such as VXLAN, which enables network administrators to create logical L2 networks across different L3 networks. The EX4650 satisfies these requirements by supporting EVPN-VXLAN L2 and L3 gateway capabilities, providing the following benefits:

Improved network and host mobility efficiency

• Control plane MAC learning to reduce unknown-unicast flooding

• Reduced Address Resolution Protocol (ARP) flooding due to MAC-to-IP binding in control plane

• Multipath traffic over multiple core switches (VXLAN entropy)

• Multipath traffic to active/active dual-homed access layer switches

Fast convergence

• Faster reconvergence when linked to dual-homed access switches fail (aliasing)

• Faster reconvergence when endpoints move

Scalability

• Scalable BGP-based control plane

• Seamless expansion of the core, distribution, and access layers as business needs grow

• Seamless expansion of campuses as business needs grow

Flexibility

• Easy integration with L3 and L2 VPNs

• BGP-based control plane functionality that allows application of fine-grained policies

Nonproprietary

• Standards-based protocols that support multivendor core, distribution, and access layers
