摘要： One embodiment of the present invention provides a system for facilitating network service virtualization. During operation, the system receives (202) a service request from a client, and initializes a communication session with the client. The system constructs (206) an interest using session state information that can identify the client and/or a previous communication session. The interest comprises a hierarchically structured variable-length name. The system then broadcasts (216) the interest to a number of servers. The system subsequently forwards to the client data received from a server which responds first to the interest.

摘要： One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network (180). An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives (500) a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines (510) forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures (520) a forwarding engine with the forwarding information. The system then forwards (530) the packet based on the forwarding information.
