    Abstract: A method, network and node device for data retransmission in network with double-layer. Management domains are arranged in the network, and virtual MAC addresses are allocated to the node devices in the domains according to predetermined convergent principle. An id which identifies the virtual MAC address domain of the node device is included in the virtual MAC address. When the network retransmits data, the node devices that are not convergent node devices encapsulate the received data with virtual MAC address, and send the data to destination node devices according to the retransmission tables of virtual MAC address. The present invention ensures that the ESP number of a destination device is not limited by the allocated VID number of PBT, increases the ESP number of a destination device, realizes 2 60 labels in finite network space, and realizes P2MP, MP2MP, multicast and broadcast in the network.

    Abstract: An access network system with separated controlling and bearing and an achieving method thereof. The system comprises: an access network control plane and an access network data plane for achieving the separation of the controlling and bearing; the access network control plane receiving the separated controlling information from the access network data plane, exchanging the controlling information with a core network, and controlling the data transferring of the access network data plane; the access network data plane separating the controlling information and the data based on the flow of the user network, transferring the controlling information to the access network control plane; transferring the data from the user network/core network according to the controlling information of the access network control plane.

    Abstract: The present invention provides a keepalive monitoring method, system and apparatus of a subscriber session to reduce the traffic flow generated when an IP edge device performs a keepalive monitoring to an access network and reduce the delay generated when the IP edge device processes the subscriber session. The keepalive monitoring method of a subscriber session includes: defining at least two subscriber sessions on at least one physical link to UE/CPE/RG through the same AN as a set of subscriber sessions, and binding the set of subscriber sessions to a L2C connection between the IP edge device and the AN; and the IP edge device performing a keepalive monitoring to the set of subscriber sessions using a keepalive monitoring mechanism of the L2C connection or a L2C message transferred on the L2C connection.
