A Streaming Media Data Distribution System Based on Network Driver Layer

Abstract

The invention discloses a streaming media data distribution system based on a network driver layer, which includes an application management module, an instruction sending module, an instruction receiving module and a data distribution module. The application management module is used for interacting with external applications, and external After the requirements are analyzed, the action requirements are transmitted to the system kernel by calling the command sending module; the command sending module is preset with a configuration interface for the application management module to call; the command receiving module hooks the command receiving function to the network command of the system when it is initialized In the linked list; when the data distribution module is initialized, the data packet processing function is connected to the network NAT interface of the system, so that the system calls the function when receiving network data, and performs data distribution according to the distribution table set by the instruction receiving module. The invention has the characteristics of high forwarding efficiency, small forwarding delay, low requirement on server performance, suitable for miniaturization, capable of transmission on the Internet, strong data security and the like.

Description

technical field [0001] The invention relates to an application layer stream media distribution system, in particular to a network drive layer based stream media data distribution system. Background technique [0002] At present, mainstream streaming media servers are implemented based on application layer network data forwarding. The implementation technology is relatively simple, but the data forwarding efficiency is low, the forwarding delay is large, and the requirements for server performance are high, which is not conducive to the development of streaming media technology. promote. [0003] The existing application layer streaming media network data distribution process is as follows: image 3 As shown, the work of the link layer, network layer and transport layer is completed by the operating system and does not need to be developed, so the development work is completely completed by the application program at the application layer. The network data packet is copied a...

Problems solved by technology

Therefore, this method has relatively high performance requirements for network switches; at the same time, due to network storms, Internet routers cut off the transmission of multicast packets, and multicast packets cannot be sent and received normally on the Internet.
