International Classification:

G06F 1516

US Classification:

Abstract:

The invention provides a method and system for content-based filtering of multicast information. A set of sources (S) which desire to distribute potentially large numbers of categories of differing information each associates a content descriptor (CD) with messages including information in those categories, so that a set of recipients (R) can receive information in at least some of those categories. A mapping server (M) associates a multicast address (MA) and a content mask (CM) with each content descriptor, so that network elements (N), such as routers, in the network can distribute only those messages which are of interest to recipients in multicast distribution trees for those multicast addresses. Each source generates content descriptors for each differentiable topic in a tree structured hierarchy, and obtains a multicast address and a content mask for the broadest content descriptor it is capable of distributing. Each recipient obtains the associated source, multicast address, and content mask, for each content descriptor of interest, and uses that information to join the multicast distribution tree for that information.

International Classification:

H04L 12/56

US Classification:

370392

Abstract:

A router receives destination address information for a packet and determines, among entries in a first forwarding table, a closest match for the received destination address information. The router receives a pointer to a second forwarding table in accordance with the closest match determined in the first forwarding table and determines, among entries in the second forwarding table, a closest match for the received destination address information.
