Embodiment Construction

[0021] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0022] as attached figure 1 Shown, the inventive method carries out route selection according to the following steps:

[0023] Step A, using a data packet capture tool at the ingress router node to capture the data packet in real time and put it into the cache queue; simultaneously collect the traffic of each link connected to the router;

[0024] In this step, real-time collection of data is performed at the ingress router node, and data packets are captured in real time by a data packet capture tool and put into the cache queue of the ingress router for business identification and traffic analysis; at the same time, the acquisition is connected to the router The traffic of each link of the link is prepared for predicting the traffic of the link at the next moment.

[0025] Step B, identifying the service category of the data packet and sending the d...

Abstract

The invention discloses an intelligent routing selection method based on flow analysis and node trust degree, which belongs to the technical field of networks and is suitable for the situation that a plurality of routings exist between an inlet router node and a target node and each routing only passes one intermediate node. The method comprises the steps of: implementing differentiation service among different businesses through business identification and marking, and then selecting a link with smaller load and higher trust degree through link flow prediction and the trust degree of an evaluation node. The method guarantees the safety at the same time of realizing load balance, thereby realizing the real-time, intelligent and dynamic routing.

Description

technical field [0001] The invention relates to a route selection method, in particular to an intelligent route selection method based on flow analysis and node trust degree, and belongs to the field of network technology. Background technique [0002] In recent years, with the development of Internet technology, network access technology has become increasingly diversified, and the management of increasingly complex networks has become the focus of attention. At the same time, the emerging new services also bring new problems to the monitoring and management of the network, and the technology of service identification emerges as the times require. Classifying and identifying various services from complex service flows is also the basis for ensuring network quality of service (QoS). [0003] On the other hand, abnormal traffic such as D0S attacks, a large amount of spam, and wanton P2P downloads occupy a huge bandwidth, causing network congestion and having a huge impact on...
