Method for monitoring P2P traffic of wide area network and system thereof

Abstract

The invention discloses a method for monitoring P2P traffic of a wide area network and a system thereof which effectively identify and monitor the P2P traffic in a wide area network environment. The method comprises the following steps: capturing a network message to acquire traffic data in a plurality of time intervals; screening network nodes in the traffic data according to the protocol type, the IP address and the port comparison technology to acquire a screening result; calculating and accumulating the data traffics which take the IP address in the screening result as a source IP or a target IP in the current time interval to acquire a screened traffic; performing traffic filtration on the data traffic in the plurality of the time intervals by adopting the port identification technology to acquire filter traffic; comparing and combining the screened traffic and the filter traffic to acquire the P2P traffic; and generating a monitoring result according to the P2P traffic acquired by the plurality of the time intervals. By acquiring and analyzing the actual traffic, the method and the system realize identification and monitoring on P2P application therein.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a wide area network P2P traffic monitoring method and system. Background technique [0002] The network monitoring system is widely used at present, and it is an important means of network security protection. Through the real-time monitoring of the network status, the network monitoring system can achieve the discovery of specific security events, the deployment of network resources, the management of network traffic and many other security purposes. It is an effective method to realize IT management and control. [0003] With the development of the network, more and more P2P applications appear in the current network environment. The P2P network structure and application can improve the utilization rate of network resources and increase the resource sharing rate, which is a major trend of future network development. However, due to the lack of unified standards and usage spe...

Problems solved by technology

In a wide area network environment, connection characteristics are often lost in massive traffic data, and it is difficult to effectively identify

Another example is that some technologies use node uplink and downlink traffic comparison technology to identify P2P applications. However, due to the unpredictability of traffic patterns in the wide area network environment and the resulting storage problems, it becomes impossible to implement
