Abstract :
Ethernet OAM is a requirement from network provider to maintain Ethernet service networks. So ITU-T developed Y.1731 protocol and IEEE developed 802.1ag protocol, they are the mainly standards about Ethernet OAM currently. Base on Y.1731, a resolution of Ethernet OAM for DSLAM is proposed and implemented successfully. The ETH-CC function is implemented by hardware to reduce consumption of the CPU resource. The transmitting MEP, receiving MEP and remote MEP should be created in hardware. The ETH-LB function is implemented by software because it is convenient and flexible and there is enough memory to store the repetitive ETH-LB result. When the ETH-CC or ETH-LB of MEP is activated a session will be created to manage the Ethernet OAM function instance.
