OTN中ODU2数据顺序调整电路的设计与实现
Design and implementation of ODU2 data sequence adj ustment circuits in OTN
摘要
Abstract
In Optical Transport Networks (OTN),the main function of the Optical Channel Data Unit (ODUk,k= 0,1,2) segmentation module is to cut ODUk into a standard sized packets (±1 byte)in a fixed format.As ODU2 is 8-byte data,the number of the remaining data bytes is different after each insertion into the packet.This paper studies the implementation method and circuit design for the remaining data processing in the above process and completes functional simulation and logic synthesis.The results show that this method reduces the resource occupation ratio and increases the circuit operating frequency to 360 MHz.关键词
