As networking devices become increasingly complex, so must the analysis equipment designed to assess their performance. Such sophisticated analysis systems must support multiple powerful routing/bridging protocol emulations that are flexible, highly scalable, and easy to use. In addition, the analysis systems must be able to generate wire-rate traffic and automatically analyze thousands of traffic flows with comprehensive QoS analysis. As a leader in performance analysis solutions, Ixia's Aptixia IxNetwork meets these requirements and is specifically targeted for the performance and functionality testing of high-speed, high-capacity routers, switches and application servers.

IxNetwork offers users the flexibility to customize the application to meet a wide range of requirements for testing complex network topologies consisting of thousands of network devices. Millions of routes and reachable hosts can be emulated within the topology. IxNetwork also provides users with the ability to customize millions of traffic flows to stress the data plane performance. Sophisticated configurations can be created using powerful wizards and grid controls in the graphical user interface. With its enhanced real-time analysis and statistics, IxNetwork is capable of reporting comprehensive protocol status and detailed per-flow traffic performance metrics.

As network functions continue to be aggregated into devices, it becomes increasingly important to consider security and encapsulation protocols, such as NAC, PPP and L2TP. IxNetwork provides the ability to authenticate emulated clients and to establish broadband sessions. Traffic can then be encapsulated over the tunneling protocols.
