基于VxWorks 的T比特路由器2.5GPOS接口板的设计

因特网流量的快速增长，对骨干网的传输提出了更高的要求，为此我们研制了总吞吐率高达1.28T 比特高性能IPv4/v6 路由器。本路由器提供2.5GPOS ，10GPOS，100M 以太网，1000M 以太网，10GLAN 以太网，10GWAN 以太网等接口，可方便组网。本文简要介绍了此路由器的体结构，并
深入研究了2.5GPOS 接口板的设计与实现。

Design and Implement based on VxWorks of 2.5GPOS Interface Board of T Bit Router Li Feng, Yang Jing (National Digital Switching System Engineering & Technological R&D Center,zhengzhou 450002,China) Abstract: The fast increase of Internet needs faster core transmission network, so we developed a high-powered IPv4/v6 router whose total throughput had reached 1.28 terabit bit. It is very convenient to set up a network because the router offers kinds of interfaces ,such as 2.5GPOS interface, 10GPOS interface，100M Ethernet interface，1000M Ethernet interface,10GLAN Ethernet interface，10GWAN Ethernet interface, and so on. This paper simply introduces the whole framework and deeply studies the design and implement of 2.5GPOS interface board. Key words: Router；SONET(Synchronous Optical Network)；SDH (Synchronous Digital
