Abstract: A method is provided for content subscription in content network. As disclosed in the method, a content requesting node in the content network receives a first interest packet comprising a content identifier through a first port from a first user device, creates a subscription entry comprising the content identifier and an identifier of the first port, sends the first interest packet to the content providing node, receives a second interest packet through a second port from a second user device; adds an identifier of the second port to the subscription entry, receives multiple data packets provided by the content providing node according to the first interest packet, and sends the multiple data packets through the first port and the second port respectively to the first user device and the second user device according to the subscription entry.

Abstract: Embodiments of the present invention provide a container name server and a method for container name resolution. The container name server includes: a network interface configured to receive a resolution request packet sent by a network node, where the resolution request packet includes a container identification of a container to be resolved; and an execution engine configured to acquire a container identification of an access container of the container to be resolved according to the container identification of the container to be resolved. In embodiments of the present invention, possibilities for solving problems such as scalability and mobility support caused by routing based completely on a content name are provided by introducing a container name server and taking the container name server as a name resolution system in an ICN network.
