Research Of Aggregation And Adaptation Technique For Different Ethernet Servieces Based On10×10Gb/S Optical Transmitter Module

With the development of the mobile internet applications, especially Internet-based video applications and P2P, the network traffic grows rapidly, which is puting forward higher requests to the capacity of the communication network.10×10Gbit/s high-speed transmission technology will become the platform the industry is of interest. While the adding of transmission rates will inevitably bring equipment replacement. We have formed the coexistence of the Gbit/s links, lOGbit/s links and40Gbit/s links. How to complete the adaptation of Ethernet applications of different rates has become a pressing problem. Currently, the existing optical cross-matrix schemes has lower speed and high cost.In this article, we focus on the study of the adaptation of Ethernet applications of different rates in the edge network, we study the methods to complete the adaptation from Gbit/s link,10Gbit/s links to10×10Gbit/s link, and schedule wavelength resources flexiblely. Finally, we proposed a method to complete the adaptation of Ethernet applications of different rates based on PIC optical transmitter module. In the article, we complete the information extraction of Ethernet service of different particle size firstly. Then we do the business segments and port polling according to the source node and the destination node. Finally, we take advantage of caching service to complete the adaptation from Gbit/s link, lOGbit/s links to10×10Gbit/s links. And thus we both utilize the existing10GE ports, and improve the idle bandwidth utilization, saving fiber through WDM technology resources.In order to verify the feasibility of the scheme, we design the FPGA solutions for the adaptation of Ethernet applications of different rates in the edge network. In one side, we complete the access to different rates of Ethernet services, and in the other side, we complete the adaptation transmission to10x10Gbit/s link. Simulation results show that compared with the existing optical cross-matrix schemes, the mothod we proposed has higher speed and lower cost. At the same time, we initially build the hardware platform, test equipment datapath functionality, and verify that equipment and network are normal and stable work. In conclusion, the proposed method is an effective aggregation scheme applied in PIC large-capacity, multi-service platform.
