Embodiment Construction

[0042] In the process of applying the H.323 protocol, when the gatekeeper finds that it cannot receive part of the signaling sent by the node on the well-known port, that is to say, the gatekeeper finds that part of the signaling sent by the node to the gatekeeper is blocked by the network such as the firewall. When the device is filtered out, the gatekeeper can realize the port redirection process through the present invention, allowing nodes to redirect to the gatekeeper through other unknown ports, thereby continuing the original business; in addition, the present invention passes through the multi-protocol switching process , to realize the communication of nodes supporting multiple protocols in networks supporting different protocols.

[0043] The first embodiment provided by the present invention is a method for redirecting network communication ports, the core of which is: when the gatekeeper as the receiving end finds that it cannot receive part of the signaling sent by...

Abstract

This invention discloses one method and network communication system to network communication position, which comprises the following steps: when receive end determines communication end for position, then sending set address to send end through communication terminal, wherein, re-position address composed of position end address; achieving receive end through re-position end address information end, wherein, the said receive end address comprises original address, management send end or new agreement receive address; the send end tests the said position address through position end address information to communicate to end.

Description

technical field [0001] The invention relates to the communication field, in particular to port redirection technology. Background technique [0002] The H.323 (ITU Recommendations on Packet Multimedia Communication System) series of protocols suggested by the ITU (International Telecommunications Union; International Telecommunication Union) is currently the main multimedia communication standard. The H.323 communication system based on the H.323 protocol includes two components: a gatekeeper (Gatekeeper) and an endpoint (Endpoint). Among them, the gatekeeper is the manager of the entire H.323 communication system, responsible for completing functions such as area management, access control, address resolution, and bandwidth management. The endpoints include nodes, gateways, MCU (Multipoint Control Unit; Multipoint Control Unit), etc., and all need to perform RAS (abbreviation of Register Call Access Signaling, H. .323 agreement between the gatekeeper and the communication...
