Digital Audio Broadcast Server Network Redundancy Technology Research And Implementation

The broadcast video system from the traditional manual method gradually to broadcast automatic hard drive, integrated multimedia technology, database technology and computer network technology, to increased the volume of information storage and improve information transmission speed . With the increase in broadcast programs and contents, the existing broadcast system has many problems, the broadcast network security is the focus should be of concern. Broadcast network to ensure uninterrupted and timely resumption of error, system requirements on developers to take full account of a series of fault-tolerant mechanism, making system has good security, fault tolerance and stability.More fault-tolerant redundant network adapter technology enterprises in the field of radio and television network broadcast audio and video programmes to provide a cheap and safe solution. Currently the market of such technology is both software and hardware support to achieve, the hardware prices is expensive. This article is in response to digital audio broadcast systems, analysis and focus on achieving security of the system broadcast network connection assurances.Audio workstation system in the broadcast media broadcast network documents requested will not have interrupted network connections, although there are currently available in the market can increase the network bandwidth, but also failed to meet there will be no disruption of network products there.This paper around the digital audio broadcast system to meet the requirements of the network connection from the client-side of the Player and server-side of the network adapter starting to analysis and design, we completed the following:First,Detailed the design of the client software player on the buffer pre-reading function modules.Second,Detailed design the dual-network adapter by the main switch monitoring software.Third,based on the middle layer NDIS driver of the double-bonding network adapter, implemented the bonding function.Finally, given the software test result, and provide an alternative method for Digital Audio workstation.
