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.

Disclosed are a system and method for aggregating micropayment hash chains. An end user (the “payer”) cryptographically signs “commitments” and transmits then to a vendor. The commitments include an “accumulated count” field which tracks the total number of micropayments made thus far in the payment transaction between the payer and the vendor. The payer can also transmit payment tokens to the vendor. These payment tokens include micropayments verified by a hash chain. When the vendor seeks reimbursement from a broker, the vendor tells the broker the total number of micropayments in the payment transaction and sends verification information to the broker. The broker checks this information against a verification system established with the payer. If the information is verified to be correct, then the broker reimburses the vendor for the services provided and charges the payer. The verification information ensures that the payer and vendor cannot cheat each other.
