Ethernet link state management device and its method

Abstract

The invention refers to a kind of Ethernet link state managing device and method. The primary processor gathers the link state information of Ethernet port connected by the message processor in the VoIP system, it can mange the Ethernet link state with high efficiency. In the VoIP system, through additional processor input circuit device, the invention can reduce the alarm sensing time when the Ethernet link occurs abnormity, thus it can reduce the time for restoring the service. Additional, the invention can assure the state of Ethernet link in real-time, it can carry on the maintenance and changing of link more conveniently, it can reduce the interruption of service extremely, at the same time, it can guarantee the consistency of service.

Description

technical field [0001] The invention relates to an Ethernet link state management, especially in a VoIP system, the main processor directly collects the link state information of the Ethernet port connected to the packet processor, and can efficiently manage the corresponding Ethernet link state An Ethernet link state management device and method. Background technique [0002] Generally speaking, the so-called VoIP (Voice over Internet Protocol) system refers to an IP telephone system composed of a series of devices that transmit voice information based on the Internet Protocol (IP). Internally transmit voice information in digital form, so as to realize voice telephone service, and provide domestic long-distance and international long-distance telephone services at the level of telephone charges equivalent to local telephone charges under the environment of the Internet and intranet. [0003] like figure 1 As shown, the conventional VoIP system required to connect an Ethe...

Problems solved by technology

Now there is such a problem that when the packet processor (12) did not notify the Ethernet alarm state, or when the packet processor (12) was not working normally, the main processor (11) just could not know the status of the Ethernet link. state

In addition, the firmware (Firmware) must go through a series of processes, that is, it must go through the communication protocol between the main processor and the packet processor to perceive the Ethernet alarm status, so there are problems such as prolonging the alarm perception time and service recovery time

[0012] In particular, there is a problem that since the VoIP system compresses and packages voice data for transmission, when the recovery time is extended, the compressed voice data cannot be restored to PCM data, resulting in a delay in service maintenance and restart. Service is maintained or restarted, and speech becomes disjointed
