Research On Experiment System And Adaptation Technique For Multi-Rates Ethernet Servieces Based On10×10Gb/s PIC Optical Transmitter Module

With the higher speed development of Internet emerging technology, such as virtualization, cloud computing, big data, higher requirements on the communication network transmission capacity of the basic network traffic transmission system. High speed transmission technologies have became the next high rate platform which draw the close attention of technology industry, and the demand of100G large capacity high speed transmission is also growing. And how to adapt the widely-used Ethernet technology to the new needs of multi services has become the industry’s concern. With the gradual commercial of40Gbit/sEthernet technology, it has formed the different granularities coexisting situation, including the Gigabit Ethernet business, the10Gigabit Ethernet and the40G bit/s Ethernet services. So how to realize the adaptation of multi-rates Ethernet services to10×10Gbit/s PIC optical transmission module up to100G transmission has become an urgent problem.This paper studies the multi-rates Ethernet services technology and the aggregation adaptation technology of multi-services. It focuses on the implementation scheme of multi-rates Ethernet services’access and the multi services adaptation transmission based on10×10Gbit/s PIC light emitting module,and the the design of the realize scheme is based on FPGA Devolpment Keyboard.The implementation scheme of services integrated access module is according to the format of standard Ethernet frame to deal with the data, with using of the cache technology to cache the business data. The design of multi service adaptation module is realized based on the round robin scheduling algorithm with priority,and the priority is determined by the particle size of access services.The paper makes full use of the existing10G bit/s port, with lower transmission costs, higher bandwidth utilization rate and fewer fiber resources by WDM technology. At the same time, this convergent adaptation scheme is based on the pure services data, so it is simple, flexible and easy to extend to higher rate Ethernet services.This paper describes the design scheme and realization process based on FPGA development board in detail. And show the simulation and debugging data results of the Gigabit Ethernet and the10Gigabit Ethernet service access unit,as well as the core processing unit, which includes the polling aggregation and service distribution function. Finally, build the experiment system basic platform system to veriflcate the experiments results. And the experimental results show that it is feasibility to study,design and implementation of multi-rates Ethernet service adaptation transmission experimental system based on10×10Gbit/s PIC optical transmitter module.
