Problems solved by technology

However, the disadvantage of RSTP is that it can only back up and protect the Layer 2 link between the MG and the Layer 3 switch, but cannot protect the Layer 3 link between the MG and the core router. Once a problem occurs on the Layer 3 link, communication It will be interrupted; the switching time is long. Although RSTP has modified the original STP protocol and made many changes in the convergence speed, because the protocol is based on topology discovery, the convergence time is still relatively long; like Trunk, due to the optical link Due to the limitation of the road itself, RSTP only supports the optical link whose port duplex mode is self-adaptive, and does not support the optical link whose port duplex mode is forced full duplex
[0008] It can be seen that the existing uplink protection technologies all have defects in varying degrees.

Embodiment Construction

[0027] The core idea of ​​the present invention is: create one to three uplink port active / standby protection groups, configure the IP service data flow in the media gateway on each port of the active and standby port groups in the protection group, and form corresponding active and standby port groups. The active and standby link groups of the standby port group, the standby port group is disabled when applied, and the system continuously detects the physical status of each port in the active port group and / or each link in the uplink active link group When the system detects that any port in the active port group and / or any link in the uplink link group is abnormal, it will switch the active and standby port groups, and at the same time, the active and standby uplink link groups will be switched. The reliability of the network is guaranteed.

[0028] The active / standby protection method of the uplink link group of the present invention can protect the entire link between the ...

Abstract

A master-backup protecting method of up-link on media gateway includes setting up up-link port protection set on MG, making master port set and back-up port set separately be energized state and forbidden state, using up-level software to continuously detect master port set and forbidding to use port of master port set when port on master port set is found to be abnormal, energizing port on back-up port set and switching master up-link set corresponding to master port set onto backup up-link set corresponding to backup port set.

Description

technical field [0001] The invention relates to the protection technology of the uplink of the next generation network (NGN), in particular to an active / standby protection method of the uplink of the media gateway. Background technique [0002] NGN is a comprehensive broadband network platform system that takes Soft Switch technology as its core and can provide multimedia services such as voice, video, and data. Its characteristics are: adopting a layered fully open network, using the technology of separation of service and call control and separation of call control and bearer, so that the service is independent of the network, and the service provision is not limited by the underlying network technology. Softswitch technology is a new call control technology developed in recent years. Due to its open architecture, packet-based transmission, and ability to provide multiple access methods, it has gradually become the traditional circuit switching to packet switching evolutio...
