Embodiment Construction

[0057] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0058] The invention discloses a streaming media service system and its attack defense system. The attack defense system is used to defend against DoS and DDoS attacks of the streaming media service system. see figure 1 , the streaming media service system includes a service host Server and at least one client client; the attack defense system is connected to the service host Server and each client client. The attack defense system includes: at least a first-class media service proxy module Proxy and a control center module. The streaming media service proxy module Proxy is responsible for the forwarding of streaming media control information and data information, the collection of various statistical information, and the final execution of defense decisions; the RTSP request sent by the Client to the Proxy is modified by the Proxy to become...

Abstract

The invention discloses a DDOS attack defense system and a method for a streaming media server application layer, the attack defense system is used for defending against DoS and DDoS attacks of a streaming media server system; the streaming media server system comprises a server host and at least one client; and the defense system is connected with the server host and the client. The attack defense system comprises at least one streaming media service proxy module and a control central module. The streaming media service proxy module is responsible for forwarding of streaming media control information and data information, collection of a variety of statistical information and final implementation of a defense decision; and the control central module is used for overall monitoring of the current state of the whole streaming media server system and emitting a command to a proxy for carrying out defense. The prospective study is based on various DDOS attacks of the streaming media RTSP, and a set of streaming media DDOS defense system based on a PROXY GROUP is designed, thereby effectively ensuring the safety of streaming media service on Internet without authorization.

Description

technical field [0001] The invention belongs to the technical field of network multimedia and relates to an attack defense system, in particular to a stream media server application layer DDOS attack defense system and method. Background technique [0002] With the rapid development of network technology and multimedia technology, streaming media technology emerges as the times require. Streaming media technology is a technology that allows users to broadcast live broadcasts, on-demand audio and video and other multimedia files through the Internet or Intranet. The streaming media server transmits media data continuously and in real time to the user computer. Users process the streaming media data through the player application, and then play back the media content. During the content playing process, the user can enjoy the media content without waiting for all the media files to be downloaded. After playback ends, no data resides on the local computer. These characteris...
