Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail according to the accompanying drawings.

[0027] The specific implementation of the system is divided into two parts, which are the system steps based on P2P service identification and flow adaptive control and the system steps of QoS routing platform based on P2P service identification.

[0028] 1, System steps based on P2P business identification and traffic adaptive control

[0029] First, identify and control the incoming traffic, that is, identify the P2P service category according to the policy management requirements. The identification method used here is the characteristic process identification method. The present invention proposes a P2P traffic identification method based on the characteristic process. A process can usually be regarded as a running activity of a program with certain independent functions on a certain data set. If the existence of a certain process can indi...

Abstract

The invention discloses a P2P service identification-based QoS routing method. In the method, a P2P service is identified by using a character process identification method, and a differentiated services code point (DSCP) value of the identified P2P service is marked, so that the DSCP values of the P2P service with various requirements are classified; and on the basis of the DSCP value classification, QoS routing is performed by using a distribution QoS routing method to differentially shunt QoS routes so as to solve the problem of network blockage caused by lasting increment of the network flow and realize the creditability of a network. The method has the advantages that: routes which can meet the requirements of different networks can be selected according to the P2P service and concrete network conditions; and realization is simple, and maintenance and management are easy. And the method can be applied to a core network.

Description

technical field [0001] The invention relates to a QoS route selection method based on P2P service identification, which belongs to the network service quality based on P2P service identification in the technical field of network communication. Background technique [0002] QoS (Quality of Service) refers to a network's ability to provide higher priority services, including dedicated bandwidth, jitter control and delay (for real-time and interactive traffic situations), packet loss rate improvement, and different WAN, Designated network traffic under LAN and MAN technologies, etc., while ensuring that the priority given to each traffic does not hinder the progress of other traffic. QoS is a security mechanism of the network and a technology used to solve problems such as network delay and congestion. Under normal circumstances, QoS is not required if the network is only used for specific application systems with no time limit, such as Web applications, or E-mail settings, et...
