Embodiment Construction

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] The present invention is a method for real-time context perception and hierarchical marking of Internet service streams. It first parses the IP packets received from the service source and perceives the service types. For real-time multimedia streams, it is necessary to dynamically perceive the status of each IP packet. The importance of 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, as well as the importance level of the IP packet in the multimedia stream layer; Then, according to the analysis result and the pre-set IP packet marking strategy, pre-mark the relevant identification field of the IP packet to minimize ...

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 high priority 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 present invention relates to a method for real-time context perception and hierarchical marking of Internet service streams, belonging to multiple technologies related to the Internet and TCP / IP protocol family, DPI feature word recognition technology, video / audio coding standards, and MPEG-2TS and RTP The field of multimedia communication technology such as real-time streaming protocol. Background technique [0002] At present, traditional IP packet flow identification and QoS control technologies only analyze 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 flow. The traditional IP router also realizes a certain degree of traffic identification and OoS guarantee through the information obtained by the quintuple. However, with the continuous enrichment of application types on the network, only analyzing the content below th...
