Embodiment Construction

[0025] Throughout the description, the preferred embodiments and examples shown should be considered as exemplars of the invention and not intended to limit the scope of protection of the invention.

[0026] The application scenarios of the embodiments of the present invention are as follows figure 1 As shown, including HSAPN network, packet switching network (for example, IP network, ATM network or FR network) and border entity (E.D) equipment, HSAPN network communicates with IP network, ATM network or FR network through E.D equipment, in HSAPN network All equipment and E.D equipment are equipped with an HSAPN address, and all equipment and E.D equipment in the IP network are assigned IP addresses. Because the addresses of the HSAPN network and the IP network (taking the most widely used IP network as an example) are different, the HSAPN network also includes an address translation entity (ADT), and the mapping relationship between the IP address and the HSAPN address is stor...

Abstract

A method and an apparatus for establishing peer to multi-peer tunnels are provided by the embodiments of the present invention. The method for establishing peer to multi-peer tunnels concretely includes a method for requesting to establish the peer to multi-peer tunnels and a method for responding the establishment of the peer to multi-peer tunnels. By branching the request message for the establishment of the peer to multi-peer tunnels and aggregating the response information for the establishment of the peer to multi-peer tunnels at the branch node, the occupation of bandwidth is reduced, and the number of messages is reduced.

Description

technical field [0001] The invention relates to the field of multicast technology, in particular to a method and device for establishing a point-to-multipoint tunnel. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the transition from analog technology to digital technology, and digital technology has experienced the transition from circuit switching technology (such as TDM) to packet switching technology (such as IP, ATM and FR). In the evolution process, the transition from TDM (Time-Division Multiplexing, Time-Division Multiplexing) technology to packet switching technology is currently underway. The following three packet switching technologies (IP, ATM, and FR) will be introduced respectively. [0003] The transition from TDM technology to ATM (Asynchronous Transfer Mode, asynchronous transfer mode) packet technology has not been realized due to technical difficulties and unsuccessful commercial ...
