Problems solved by technology

However, most of today's traffic characteristic parameters are classified and analyzed based on the time-domain characteristic parameters of the flow, and these time-domain parameters are easy to change with the complex network environment space and time changes.

Abstract

The identification method of the DVB-RCS protocol of the present invention, one is to send the control information to the RCST through the network control center, thereby obtaining the forward link signaling information, and the RCST analyzes the forward link signaling information according to the signaling table, and through the translation code to complete the identification of DVB‑RCS protocol; the other is to send control information to RCST through the network control center. Send the contract, and then complete the identification of the DVB‑RCS protocol through the traffic statistics of the data service burst. Identifying the DVB‑RCS protocol through two methods can improve the accuracy of identification and is suitable for the increasing trend of network information capacity today.

Description

technical field [0001] The invention belongs to the technical field of blind identification, and more specifically, relates to an identification method of a DVB-RCS protocol. Background technique [0002] Today's broadband market is experiencing a "two-dimensional" rapid growth: on the one hand, the number of broadband users continues to grow, and the number of global broadband users has exceeded 300 million; on the other hand, the network bandwidth continues to increase, from 512K to 1M, 2M , even 10M. Along with this growth, broadband applications are also showing a trend of diversification. In short, digitalization of analog signals (VoIP: Voice over Internet Protocol) is the integration of, peer-to-peer networks (P2P: PeertoPeer), online games, video... Various innovative applications continue to attract new users, making the broadband world more colorful, and at the same time making operators' network management and operation and maintenance work more complicated.
