Method and apparatus for content-based routing and filtering at routers using channels
First Claim
1. A method for configuring a channel to facilitate content-based routing, comprising:
- establishing a channel providing a logical communication path between a plurality of nodes in a publish-subscribe network;
configuring the channel for use in content-based routing of information over the communication path; and
selecting a message format for transmission over the communication path based upon the channel.

Abstract
Channels between routers for use in packet routing via payload inspection. The channels constitute logical connections between routers and include subjects and attributes. Publishers create channels for routing particular types of content as defined by the subjects and attributes. The publishers also create proxies and notifications on the channels. The channel definitions for routers identify packet or message structures so that the routers can locate attributes in the packets for content-based routing. The routers apply the packet attributes to filters encapsulating subscriptions in order to perform the content-based routing in the network core. The routers also locally cache content, providing distributed caching of content throughout the network core.
