基于全IP开发平台的NP7250的数据转发机制
Mechanism of Data Transmission Based on NP7250 in All-IP Developing Platform
摘要
Abstract
Traditional mobile network products were developed independently,which were not developed on a unified hardware and soft-ware platform. But multi-services integrated developing communication platform based on IP can avoid repeated work due to various modules developed independently. Present a scheme about all-IP developing platform oriented to communication field based on AMCC's switch chipsets including NP7250,NPX5700 and NPX5800,all-IP developing platforms have two level switching architecture. One-level switching is based on Crossbar+line card,two-level switching is Ethernet way. It mainly introduced designing scheme of data transmis-sion module based on the network processor-NP7250. The data transmission module included three major parts:the first part is the core routing module;the second part is one-level switching module;the third part is two-level switching module. Realize the basic cell and packet routing and forwarding function on the platform.关键词
