Network driver layer-based streaming media data distribution system

Abstract

The present invention discloses a network driver layer-based streaming media data distribution system. The system comprises 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 the external application, analyzing the external demand and transmitting the action demand to a system kernel through invoking the instruction sending module. The instruction sending module is preset with a configuration interface for being invoked by the application management module. During the initializing process of the instruction receiving module, an instruction receiving function is hooked to the network instruction linked list of the system. During the initializing process of the data distribution module, a data packet processing function is hooked to the network NAT interface of the system, so that the system is enabled to receive network data while invoking the above function. Meanwhile, the data distribution can be conducted according to a distribution table preset by the instruction receiving module. The system is high in forwarding efficiency, small in forwarding delay, low in requirement on server performances, applicable for miniaturization and strong in data security. Therefore, the system can be used for transmitting data over the internet.

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.
