摘要： A reliability processing method and system in networking of Metro Ethernet Network providing multi-service are provided. The method includes: establishing a Virtual Router Redundancy Protocol (VRRP) group with at least two service control gateways, establishing network connections between an access device (UPE) and the service control gateways in the Virtual Router Redundancy Protocol group by a Virtual Private LAN Service (VPLS); establishing Layer 2 service and Layer 3 service connections between an active service control gateway and the Access device after active and standby service control gateways in the Virtual Router Redundancy Protocol group are determined according to a processing result of a Virtual Router Redundancy Protocol message, and performing Layer 2 service and Layer 3 service processing. With the present invention, when the MAN service is in fault, all the Layer 2 and Layer 3 services may be switched to the standby service control gateway quickly, and the switching may be on the order of milliseconds. Therefore, the reliability of the Layer 2 and Layer 3 services of the MAN may be sufficiently guaranteed, and the overhead of the system may be reduced significantly.

摘要： The present invention discloses a method, system and device for removing Media Access Control (MAC) addresses. The method includes: sending, by a first User-facing Provider Edge (UPE), a MAC Address Withdraw message, when a handover happens on an access network; receiving, by a network provider edge (NPE), the MAC Address Withdraw message; and removing, by the NPE, a Backbone Media Access Control (B-MAC) address table corresponding to a Virtual Private LAN Service (VPLS) network and forwarding the MAC Address Withdraw message, if the message carries no specific identifier; or directly forwarding, by the NPE, the MAC Address Withdraw message, if the message carries a specific identifier. In the present invention, a specific identifier is added to a MAC Address Withdraw message so as to avoid unnecessary MAC address learning by NPE and UPE devices and to reduce the impact, caused by MAC address learning, on network devices.

摘要： Embodiments of the present disclosure disclose a method and an apparatus for protecting a subscriber access network, and relate to the field of communications. The method includes: connecting a Broadband Network Gateway BNG device and N predetermined Digital Subscriber Line Access Multiplexers DSLAMs to an aggregation device AGG; allocating an active BNG interface for each of the N DSLAMs, allocating a standby BNG interface set for the N DSLAMs to obtain a backup relationship, and sending the backup relationship to the AGG (102); and backing up subscriber data on the DSLAMs to the standby BNG interface set, so that when an active BNG interface fails, the AGG switches subscribers on a DSLAM served by the failed active BNG interface to a standby BNG interface in the standby BNG interface set.
