Distributed adaptive listening system, generation and monitor control method

Abstract

The invention relates to the communication safety supervising field, and provides a distributing type adaptive listening system and a generating and listening control method thereof. The listened domain of the listening system is generated based on a propagation model. The listening system comprises an operational management and maintenance module OAM, a listening agent management module IAMF anda listening information collection module IICF, as well as a listening agent functional module IA. The management domain of the system is composed of the OAM, the IAMF and the IICF, and the listened domain where the IA is positioned is listened, managed and controlled. The system overcomes the difficulty that a distributing type network is difficult to listen, has the advantages of highly-efficient distributed character, intelligent transmissibility and stable robustness, and is suitable for the network supervising field, in particular to the distributing type network supervising field.

Description

technical field [0001] The invention belongs to the field of communication security, and relates to VoIP (Voice over IP), P2P (Peer-to-Peer) voice communication and methods for real-time signaling flow monitoring and media flow monitoring of other distributed voice communication systems, in particular to distributed Adaptive P2P-VoIP monitoring method. Background technique [0002] VoIP system is based on IP, low in cost, fast in deployment, and fully utilizes the Internet, so it has developed rapidly in recent years. With the increase of users, the traditional VoIP system based on C / S (Client / Server) mode is completed by the central server to complete functions such as management, registration, authentication, call processing and media forwarding, resulting in an increase in server load, which is likely to become a system bottleneck and a single point fault source. Therefore, P2P technology was gradually introduced into VoIP, which broke through the bottleneck of the C / S...

AI Technical Summary

Problems solved by technology

[0009]2. In addition to the distributed characteristics of the P2P-VoIP network, the voice transmission also has the characteristics of multipath, which is necessary for setting reasonable monitoring points to capture and reconstruct different Same Conversational Voice on the Path Presents Big Challenges

[0010]3. In the P2P VoIP network, the failure caused by monitoring will lead to the failure of monitoring in the monitoring area of ​​the agent, which will cause the system robustness to decline and the monitoring command to be unexecutable , affecting the availability of the system
