Juniper switching platforms provide a high-density, high-performance foundation for your most demanding data center and cloud environments. As your business grows, your data center must scale to accommodate increased network traffic and users, without compromising scalability, manageability, and sustainability. Our data center architectures support dozens to thousands of ports, scaling to address your evolving business needs while maximizing agility and investment dollars.

Modern data centers running at scale typically use an IP fabric architecture with EVPN-VXLAN overlay.

• An IP fabric enables you to collapse traditional networking layers into a two-tier spine-and-leaf architecture optimized for large-scale environments. This highly interconnected Layer 3 network acts as an underlay to provide high resiliency and low latency across your network.

• The EVPN-VXLAN overlay sits on top of the IP fabric. It enables you to extend and interconnect your Layer 2 data center domains.

Powered with a robust control plane, faster convergence, and flexible deployment models, this standards-based fabric helps your data center become multicloud ready.

For smaller scale data center networks, you can use our Virtual Chassis technology in the leaf layer to create pairs of devices connected together. You can configure and manage them as a single, logical device.

Data Center Network Management
A management platform helps you simplify data center operations and manage network resources as a single, cohesive infrastructure. Juniper's Apstra solution enables you to easily manage your physical data center infrastructure. 

This solution provides intent-driven automation for deployment along with robust monitoring for assured operation, enabling you to automate, manage, and monitor your data center fabric.

Juniper’s Virtual Chassis Fabric to  EVPN/VXLAN IP Fabric Migration  service manages the transition  of Virtual Chassis Fabric data  center deployments to new EVPN  platforms, using proven methods  and tools to provide a high degree  of confidence, speed to completion,  and reduced risk.  

This service is designed to interconnect and then incrementally migrate all elements  from the existing Virtual Chassis Fabric system to the new IP fabric 

Juniper Professional Services  QFabric to EVPN/VXLAN IP  Fabric Migration service manages  the transition of QFabric data  center deployments to new EVPN  platforms. Proven methods and  tools are used to provide a high  degree of assurance, speed to  completion, and reduced risk. 

As content and applications migrate to the cloud, the demand for network bandwidth is accelerating, and users’ quality-of-experience (QoE) expectations are reaching new heights. At the same time, service provider networks are struggling to keep pace using their current transport architectures and management approaches.

To more easily and affordably meet demand and improve user experiences, service providers need a network transport solution that will provide greater control, agility, application awareness, and simplified traffic management for their networks. Operators can get all these capabilities with Juniper’s segment routing solution.

Because the SR ingress node encodes path information in the SR header, transit nodes are not required to maintain information regarding each path that they support. They are only required to process the segment identifiers found in the packet header, forwarding the packet from the current segment to the next segment.

This is the major benefit of SR. Because transit nodes are not required to maintain path information, overhead associated with maintaining that information is eliminated. As a result, routing protocols are simplified, scaling characteristics are improved, and network operations become less problematic.
