Latest Patents
Harrington holds a patent titled "Multicast IP zones for fast spanning tree convergence in wide-area packet network systems." This invention focuses on systems and methods for confining multicast routing trees within single zones of multi-zone communication systems. By enabling faster convergence of the trees, his invention improves the overall performance of packet networks. The patent describes how separate multicast routing trees are established using different multicast addresses in a source zone and one or more listening zones. Packets for a call are distributed by routers within the source zone via a source zone multicast address. The source zone packet duplicator forwards these packets using unicast routing to various listening zone packet duplicators, which then distribute the packets within their respective zones.
