Appendix A: New Features Supported on Line Cards

When multiple routers are connected together, only the router using Network Address Translation requires the -AA or T-series line card. In Diagram 2, only Router W requires the -AA or T-series line card since it is the only router performing translation to the global Internet. Note that Routers A and B are connected to the -AA or T-series line card on Router W.

Load Balancing (LSNAT)

Load balancing distributes clients’ requests to a predefined group of servers with no changes required on the clients or servers. To distribute requests to multiple servers, a server group must first be created with a virtual server address. Servers can then be added to this server group to handle clients’ requests through the virtual server address. The SSR forwards requests to servers inside the servers group according to a load-sharing algorithm. The SSR currently supports three types of load-sharing algorithms: round- robin, weighted-round-robin, and least-loaded.
