Embodiment Construction

[0041] The core of the present invention is to obtain the link state of the SIP network node through the general SIP protocol, that is, to use the existing SIP message / operation in the SIP protocol standard to complete this function, so as to ensure the generality of the solution. Moreover, a SIP node uses the SIP protocol to subscribe to other node status change messages and accept the change information, that is, when a SIP node has obtained the status of another SIP node, the node notifies other nodes of the status information of the monitored node. SIP nodes to reduce the number of network transfers and SIP messages required to maintain node state.

[0042] Those skilled in the art know that standard SIP messages are based on plain text. A message consists of four parts: start line, message header, blank line and message body. in,

[0043] The start line is divided into request line and status line, corresponding to SIP request message and response message respectively. ...

Abstract

This invention discloses one method and system to get the initial dialogue network joint, wherein the method comprises the following steps: setting dialogue initial agreement SIP management points; monitoring the SIP network other points through the standard SIP messages; getting other joints status information through management joint order information. The system contains the following parts: at least one reliable servo to provide network linkage; status management servo to monitor network linkage status; at least one reliable order servo to order the forms of the servo joint changes to the status management servo.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for acquiring the status of SIP network nodes. Background technique [0002] SIP (Session Initiation Protocol) is a protocol developed by IETF for controlling IP-based multimedia communication systems. It defines the signaling process for controlling multimedia sessions, including session establishment, teardown, and modification. It is a an application layer protocol. A session refers to an application-level link between two SIP nodes. Specific tasks may be multimedia links, such as Internet phone calls, multimedia broadcasts, multimedia conferences, and the like. The SIP protocol is only responsible for enabling communication, and needs to cooperate with RTP (Real-time Transport Protocol) and SDP (Session Description Protocol) to complete the communication function. [0003] A SIP node can have multiple working modes, such as UserAgent (user...
