Design of the Multicast Controller for the High-Capacity Internet Router

High-capacity routers that circulate multicast packets have unique properties. Their architecture is non-blocking even for the multicast traffic. It also provides delay guarantees. This paper presents the detailed implementation of the controller that circulates multicast packets through a router toward their destination ports. The controller was implemented on the FPGA device and its functioning was tested. Its scalability and speed were assessed, and shown to be satisfactory.
