Abstract: Methods and systems for loading and receiving traffic from a broadband communication link, such as an OC-3, link are disclosed. A system for loading a broadband communication link includes a simulated traffic generator for generating simulated traffic to be sent over the broadband communication link. Cascadable processing modules receive and aggregate the simulated traffic to load a broadband communication link. The cascadable processing modules can also receive and process data from a broadband communication link. Each cascadable processing module filters and processes a portion of received traffic. A single platform can be configured to simultaneously load a broadband communication link and receive traffic from the broadband communication link.
