Content networking is an emerging technology, where the requests for content accesses are steered by "content routers" that examine not only the destinations but also content descriptors such as URLs and cookies. In the current deployments of content networking, "content routing" is mostly confined to selecting the most appropriate back-end server in virtualized web server clusters. This invention presents a novel content-based routing architecture that is suitable for global content networking. In this content-based routing architecture, a virtual overlay network called the "virtual content network" is superimposed over the physical network. The content network contains content routers as the nodes and "pathways" as links. The content-based routers at the edge of the content network may be either a gateway to the client domain or a gateway to the server domain whereas the interior ones correspond to the content switches dedicated for steering content requests and replies. The pathways are virtual paths along the physical network that connect the corresponding content routers. The invention is based on tagging content requests at the ingress points. The tags are designed to incorporate several different attributes of the content in the routing process. The path chosen for routing the request is the optimal path and is chosen from multiple paths leading to the replicas of the content.
