Abstract


The emergence of optical communication technology has brought to the booming field of communication opportunities , optical technology penetration in the entire communication network , optical fiber communication has the all-optical network (AON) advancing trend. Since the electronic exchange process \In this case, the optical cross-connect (OXC) and optical add-drop multiplexing (OADM) device to become large -capacity communication backbone network construction of the main equipment . Therefore, switching equipment for optical networks is to improve the performance of research studies focus . In this paper, all-optical network and its node device , node interleaving module theoretical basis for the study and discussion , as a basis for cross- module structure made ??of two different routing algorithms and system optimization program, divided into three major parts: First of all-optical network structure and evolution , and the two kinds of optical network switching equipment were introduced, in-depth study of the optical cross-connect devices which function evaluation , the basic structure and its implementation. The second section discusses CLOS network of multi-stage switching , the part of the optical cross-connect theory of cross- module , focusing on the different characteristics of the three blocking CLOS network and gives such a network congestion conditions . Finally , we propose a cross- module switching node routing equipment scheduling algorithm and system optimization. The cross module is typically implemented using two CLOS network , based on rearrangement blocking CLOS network strictly non-blocking cross- module -based and cross CLOS network modules. Both approaches have advantages and disadvantages , and therefore the characteristics of the different methods , based on the rearrangement of the non-blocking cross CLOS network routing module scheduling algorithm proposed a new network based on strictly non-blocking cross- module routing CLOS algorithm to compare the pros and cons of the two types of routing algorithms . Design and Verification of system optimization program for optimization are presented and analyzed simulation results . Finally, the article summarizes research in optical cross-connect the device to work in an important innovation .
