One embodiment of the present invention provides a system for facilitating network service virtualization. During opera tion, the system receives a service request from a client, and initializes a communication session with the client. The sys tem constructs an interest using session state information that can identify the client and/or a previous communication ses sion. The interest comprises a hierarchically structured vari able-length name. The system then broadcasts 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.
