Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 The internal composition structure of a network element 100 is given. The network element 100 is a communication system, which is composed of multiple access nodes connected to the external network, multiple signaling processing modules, and multiple session processing modules. The multiple access nodes are respectively access node 1 and access node 2, the multiple signaling processing modules are respectively signaling processing module 1 and signaling processing module 2, and the multiple session processing modules The modules are session processing module 1 and session processing module 2 respectively.

[0032] Each access node may have a plurality of external ports, which are respectively connected to the external network for communication, and are responsible for receiving external packets, and classifying and forwarding...

Abstract

The invention discloses a communication system that realizes link measurement and link measurement method thereof. The link measurement method includes the steps of: configuring a probing message by an access node, parsing the probing message to obtain a piece of single link probing data and report it to a network management back stage or send the probing message to the access node. The access node parses the sent probing message to obtain a piece of double link probing data and report it to a network management back stage; the network management back stage obtains the link state information in real time according to received single link probing data and double link probing data. The measurement method of the invention based on an active measurement technology analyzes inner link quality problem in the signaling message in the system and positions the problem rapidly in the system, which improves problem screening efficiency.

Description

technical field [0001] The invention relates to a communication system in an IP network and a method for measuring internal links thereof. Background technique [0002] With the advancement of next-generation network construction and network integration, IP (Internet Protocol, Internet Protocol) packet technology is being widely used in telecommunication networks, and traditional telecommunication networks are gradually becoming IP-based. The contradiction between high availability required by telecommunication equipment and quality of service guarantee has become a problem that must be solved in the communication system based on IP. In order to collect relevant index data reflecting link quality, such as link connectivity, packet loss rate, delay, and jitter, it is necessary to use network measurement technology to measure and analyze the communication system. At present, the most commonly used measurement and analysis method is to connect a network analyzer to the switch ...
