The internal high - speed interconnection network of high - performance computer systems is a key factor in restricting the overall system performance , high bandwidth, low latency interconnect and exchange system is the most important performance indicators . High - performance parallel computer has been used electrical the interconnect switching technology , but electrical interconnection in bandwidth interconnect density , contorted clock , limit energy consumption, interference immunity , as well as the rapid development of optical devices , making light mutual even with the exchange of technology by the unprecedented attention . , Devices based on fiber optics and high-speed optical interconnect has been successfully used in high - performance computer systems to overcome the photoelectric conversion delay , and explore all - optical switching imminent . The subject first in-depth study and analysis of the optical wavelength switching , optical burst switching and optical packet switching basic principles , methods and key technologies , combined with demand for high - performance computer systems and electric interconnection network research of the three kinds of light switching technology to conduct a comparative analysis , the study shows that the optical packet switching technology can best meet the high-performance computer systems , optical switching technology . The realization of light exchange SOA , VOA and holographic optical device technology works , development and trends based on optical switching technology research , the subject of the analysis and research , studies have shown that the SOA device technology to achieve optical packet switching is the most the potential of high-performance computer systems , optical switching implementations . The subject on the basis of in -depth analysis of the Data-Vortex optical packet switching model for the complex network structure , system injection rate low shortcomings , propose a SOA-based optical packet switching model - SSDB, describe its working principle and the switching node design. Finally , this topic OMNet simulation tools on of SSDB the topology working mechanism and node design , modeling, simulation , and analysis , and the results show that the SSDB network model has a high injection rate and lower network delay .
