摘要 随着网络规模的扩大和用户需求的增加,大客户的概念有所扩展,总部-分支的网络应用越来越广。采用何种接入技术,降低组网、维护成本,满足客户实际需求是当前网络建设的焦点。通过对CPOS网络的架构的研究,提出2.5G CPOS网络FPGA设计的总体方案,重点突破2.5G CPOS网络的接入、解析、通道化处理等关键技术的研究和实现,并选用Altera公司的FPGA芯片进行设计实现,加载到FPGA芯片用QUARTUS II信号采集工具Signaltap进行采样验证。 With the increase of network scale and requirements of users,the concept of large customers is expanded, and the application of headquarters-branches network becomes become much wider. What kind of access technologies should be used to reduce network maintenance costs and meet customers' demand is now the focus of network construction. Based on the study of CPOS network architecture, the overall solu-tion of FPGA design for 2. 5G CPOS network is proposed, with emphasis on the breakthrough of key tech-nologies including access, analysis and channel process. Meanwhile, Altera's FPGA chip is selected to load onto FPGA chip, thus with QUARTUS II signal acquisition tool Signaltap for sample verification.
