Problems solved by technology

[0004] Large domestic video sites such as Sohu, iQiyi, and Youku have adopted FLASH P2P technology to reduce expensive bandwidth expenses. However, none of the three major sites has localized FLASH P2P, resulting in huge P2P traffic to the operator's backbone. The network is under great pressure

Embodiment Construction

[0032] The traffic localization optimization processing method in the FLASH P2P on-demand system solves the problem that a large amount of FLASH P2P traffic causes a large traffic pressure on the operator's backbone network. In the selection process of nodes, local nodes are the main nodes, and non-local nodes are used as data copies. The following FLASH P2P VOD system traffic localization process, its corresponding flow chart and sequence diagram are as follows figure 2 , image 3 As shown, the specific process is as follows:

[0033] (1) The process of traffic localization

[0034] The specific steps are as follows:

[0035] (1) When the node requests a video, the node will request the first video slice from the redirection server.

[0036] (2) The redirection server will redirect the request to the video storage server.

[0037] (3) The node acquires video slices from the video storage server and plays them.

[0038] (4) The node applies for a PEERID (unique 256-bit cha...

Abstract

A flow localization optimization processing method in an Internet video-on-demand system includes: a node periodically reports its own network status, IP address, playback progress, and bitmap to a Tracker server. According to the request of the node, the Tracker server selects nodes in the same area to form a list and sends it to the node. The node selects 6 nodes with the requested data block by analyzing the bitmap of the nodes in the peerList, and simultaneously responds to the 6 nodes Nodes send connection requests until the first node responds, and then data transfer occurs with the responding node. If the local node is not enough to ensure the smooth playback of streaming media, the node requests the non-local node from the Tracker server for P2P sharing. While ensuring traffic localization as much as possible, by adding non-localized node support reasonably, it can reduce the time delay when users receive on-demand programs in the FLASH P2P video-on-demand system, improve the fluency of video playback, and greatly reduce the traffic of operators' backbone networks pressure.

Description

technical field [0001] The present invention provides a traffic localization optimization processing method in the FLASH P2P on-demand system, which is mainly used to solve the problem that the excessive P2P traffic occupies the bandwidth of the backbone network in the webpage video on-demand based on the FLASH platform, and maximizes the user experience while ensuring the user experience. Minimizing the occupation of P2P traffic on backbone network traffic belongs to the field of computer networks. Background technique [0002] FLASH P2P is a P2P technology implemented on the FLASH platform developed by Adobe, which is based on RTMFP (Real-Time Streaming Media Protocol). Adobe introduced the RTMFP protocol in Flash Player 10 and subsequent versions. The RTMFP protocol provides a high-quality communication solution for live broadcast and real-time communication programs. [0003] RTMFP uses UDP to transmit data to increase the speed of data transmission, and uses a connect...
