| 摘 要： | 给出了基于AMCC的NP7250、NPX5700和NPX5800交换套片的全IP交换平台的构建方案,重点介绍了在基于Vxworks的全IP交换平台上的进程通信模块的设计和实现方案。模块主要实现相同处理器内和不同处理器之间进程间通信功能,进程间的通信主要依靠调度任务从邮箱中接收消息,并把消息派发到各个进程的消息队列来实现,底层协议类型包括可靠通信协议(TCP)和不可靠通信协议(UDP)。

| Abstract: | This paper presented a schema about all-IP platform based on AMCC＇s switch chipsets including NP7250, NPX5700 and NPX5800 , mainly introduced designing and realization methods of the processes communicating module on the all-IP developing plat- form. It mainly realized processes communicating in the NPU and between NPUs. The scheduled task received messages from the mail- box and dispatched them to the message queue of the processes to realize the communication function between processes. The bottom protocols included TCP and UDP |
