A Proposed FPGA Design and Implementation of Quintuple Service Identification Module for 10G EPON ONU

Abstract

As one of the mainstream technical solutions for optical access network, 10G EPON is increasingly favored by telecommunications suppliers. However, only as a simple two-layer bearer system, 10G EPON has defects such as transparent data transmission and lack of concern for protocols and services. As a result, the 10G EPON system is not efficient in carrying new services such as web video services, P2P services, VoIP services, instant messaging services, streaming media services, and online game services, and the bandwidth is seriously wasted. For this reason, this paper designs a set of 10G EPON ONU implementation scheme that supports service identification, and then implements FPGA implementation on the core modules of the DPI part of the scheme, such as quintuple identification, port identification, uplink packet feature extraction cache, data FIFO and other sub-modules. Finally, a simulation test is carried out on the designed scheme. The results show that the accuracy rate and recall rate of the two main indicators of the services identification function have reached more than 90% and 80% respectively, and the expected design goal has been completed.
