基于UTOPIA接口的数据采集设计与实现

摘要

通过对信元的深入分析,提出基于ATM技术的UTOPLA接口的IP数据包的提取方法.用FPGA实现ATM层的数据分装与重组,可大大提高转换速度,然后通过对CpCS-PDU的分析采用软件提取IP数据包,最后给出了基于UTOPLA接口的信元提取的仿真结果.%This paper analyses cells and puts forward the ways of abstraction of IP data packet based on UTOPIA. Realizing packet segmentation and reassembly of ATM layer with FPGA can raise the conversion speed greatly. After analyzing the CPCS - PDU, users can adopt software to pick up IP data packet. The text finally provides virtual results based on UTOPIA.
