Catalyst 6500 Sup2T Network Virtualization via MPLS/VPLS Performance

Visit the Link

Network virtualization, or the ability to divide a physical network into multiple logical networks with unique attributes, is a design that has grown in popularity as IT business leaders have sort ways to segment their network with different attributes for different user groups. This is popular in healthcare, education, travel and other industries. Network virtualization can be implemented either in IP, and/or MPLS. In addition connecting the Catalyst 6500 directly to service provider MPLS networks is another popular design; therefore we test throughput performance for both scenarios here.

For active-active data center operation, disaster planning and load balancing are best practices when connecting data centers via MPLS or VPLS. VPLS layer 2 connected data centers deliver LAN-like service over the campus and/or wide area network. Layer 2 connectivity is important as server-server communications expect layer 2 connectivity as most applications have been designed with this assumption. For connecting more than two data centers, VPLS offers mesh connectivity. Data centers connected via VPLS look and act as if they are on the same LAN. Therefore, we test that VPLS throughput performance rates are equally high performance in this scenario as MPLS.
