一种基于FPGA的媒体网关设计与实现

基于IP的软交换网络实现话音业务并能与PSTN交换网实现互联互通,关键要解决网络之间的信令互通和话音互通。现给出了一种与PSTN交换网络能够实现互通的一种媒体网关的硬件、软件和FPGA设计的实现方案介绍,该设计方案采用模块化设计,单板接口数量多,可通过控制软件灵活配置,还兼具有可扩展性。对媒体网关中FPGA的整体设计方案,以及上行数据处理和下行数据处理部分中各个模块的设计和功能进行了比较详尽的介绍,其中下行数据处理模块设计中还兼具有保证Qos的一种方法。

Design and Implementation of Media Gateway based on FPGA

Softswitch-based IP networks implement voice services and realize interoperability with PSTN exchange network.For this,it is critical to solve the signaling interworking between the network and voice exchange.This paper proposes an implementation scheme of hardware,software and FPGA design for media gateway interoperable with PSTN switching network.This scheme adopts modular design,many interfaces in each board could be flexibly configured through the control software and are of scalability.The overall desi...
