Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The present invention is a method for real-time context awareness and hierarchical marking of Internet service flows. It first parses the IP packets received from the service source to perceive the service types. For real-time multimedia flows, it is necessary to dynamically perceive the status of each IP packet Importance in the service stream; if the real-time multimedia stream adopts layered coding, it is necessary to perceive the importance level of the multimedia stream layer where the IP packet is located, and also perceive the importance level of the IP packet in the multimedia stream layer; Then, according to the analysis result and the preset IP packet marking strategy, pre-mark the relevant identification field of the IP packet, so as to reduce the...

Abstract

The invention provides a real-time context perceiving and classification marking method of internet business flow, comprising the following steps: analyzing IP data packet received from a business resource terminal; perceiving business types thereof; dynamically perceiving importance of the each IP data packet in business stream for real-time multimedia stream; if the real-time multimedia stream is coded by the means of classification, not only perceiving importance level of the stream layer at which the IP packet is positioned, but also perceiving importance level of the IP packet in the stream layer; and according to an analyzing result and a preset IP packet marking strategy, previously marking correlative mark field of the IP packet. The method can be taken as foundation of marking algorithm for a traditional internet router or an autonomy network inlet edge router based on diffserv, to divide the IP packet with different importance into different QoS levels, minimize lose of highpriority IP packet when the network blocks, heighten probability for successfully transmitting the IP packet for bearing important information, and provide effective QoS guarantee for a user.

Description

technical field [0001] The invention relates to a method for real-time context awareness and hierarchical marking of Internet service flows, which belongs to the Internet and TCP / IP protocol family, DPI feature word recognition technology, multiple technologies of video / audio coding standards, and MPEG-2TS and RTP The field of multimedia communication technology such as real-time streaming transmission protocol. Background technique [0002] Now, the traditional IP packet traffic identification and QoS control technology only analyzes the five-tuple information in the IP packet header: source address, destination address, source port, destination port and protocol type to determine the basic information of the traffic. A traditional IP router also implements a certain degree of traffic identification and OoS guarantee through the information obtained from the quintuple. However, with the continuous enrichment of application types on the network, it is impossible to truly ju...
