Abstract: Methods and apparatuses for routing and forwarding, establishing a routing table, and acquiring content are provided. The method for routing and forwarding includes: receiving a content request packet, where the content request packet carries a content name of requested content and container information of the requested content; determining whether any forwarding entry that matches the content name of the requested content exists in a FIB; determining whether any forwarding entry that matches the container identifier in the container information exists in the FIB when no forwarding entry that matches the content name of the requested content exists in the FIB; and when a forwarding entry that matches the container identifier in the container information of the requested content exists in the FIB, sending the content request packet according to a port in the matched forwarding entry.

Abstract: The present invention discloses a data source movement processing method, a packet forwarding method, and an apparatus thereof, which are applied to an information centric network (ICN). The data source movement processing method includes: when a target container from a first container enters a second container, registering a route of the target container in the second container; communicating with a resolution system, so that the resolution system updates an access container of the target container from the first container to the second container. In the data source movement processing method according to the embodiment of the present invention, a data source movement is supported without introducing frequent and cumbersome route updates and without changing a content name of content, thereby maintaining persistence of the content name, enhancing feasibility of an ICN architecture, and improving user experience.

Abstract: A method is provided for content subscription in content network. 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.
