20120327938 | MESSAGE TRANSMISSION IN VIRTUAL PRIVATE NETWORKS - The disclosure relates to a method for transmitting a message in a Hierarchical Layer 2 Virtual Private Network (H-L2VPN). A destination MAC address, to which a message is to be forwarded upon receiving the message, is determined by a first peer node of the network. The first peer node determines whether one or more equivalent pseudo wires (PWs) connected thereto form a path to the destination MAC address. When it is determined that more than one equivalent PW forms a path to the destination MAC address, an arbitrary equivalent PW is selected from the more than one equivalent PW by the first peer node. The first peer node sends the message, via the selected equivalent PW, to a second peer node of the network connected to the selected equivalent PW for forwarding to the destination MAC address. | 12-27-2012 |
20130044591 | ENABLING LOAD BALANCING FOR MPLS-TP - A method of and a device for enabling load balancing for Multiprotocol Label Switching Transport Profile (MPLS-TP) are provided. The method is applied to a process of transmitting data between two Provider Edge (PE) devices that adopt a protection mechanism of primary and backup tunnels. The method comprises allocating, by a source PE device located at a head node of a tunnel, traffic to each of the primary and backup tunnels in a current transmission period based on transmission performance information about each of the primary and backup tunnels in a previous transmission period fed back by a destination PE device located at a tail node of the tunnel, when a set transmission period comes; and obtaining, by said source PE device, the traffic allocated to each of the tunnels and transmitting data to the destination PE device via the corresponding tunnels. | 02-21-2013 |
20130089096 | METHOD AND SYSTEM FOR MANAGING PROTOCOL CONNECTION IN PBB NETWORK AND BEB NODE - A method and system for managing protocol connection in a PBB network and a BEB node. A first BEB node in the PBB network receives a Pseudo Wire (PW) connection requesting message sent by a second BEB node which has a PBB instance. When it is determined according to the PW connection requesting message that the first BEB node has the same PBB instance as that of the second BEB node, the first BEB node sends a PW response message back to the second BEB node and establishes protocol connection between the first BEB node and the second BEB node for forwarding backbone frame. | 04-11-2013 |
20130173788 | NETWORK ACCESS APPARATUS - A network access apparatus comprising a tunneling interface to collect device access information of network devices of a first computer network having a first network gateway device and device access information of network devices of a second computer network having a second network gateway device, wherein the apparatus is to send device access information of network devices of said first computer network to said second computer network upon receipt of an inquiry for request of device access information from said second computer network, and vice versa. | 07-04-2013 |
20130259042 | MULTICAST PACKET TRANSMISSION - A method for multicast packet transmission by a first provider edge device in a virtual switching instance, in which the first provider edge device transmits, to a second provider edge device in the virtual switching instance, a packet having an address of a private network multicast group and an address of a public network multicast group associated with the private network multicast group. The first provider edge device receives, from the second provider edge device, a join request packet to join the public network multicast group. The first provider edge device stores forwarding information for the public network multicast group, wherein the forwarding information relates to an interface over which the join request packet is received by the first provider edge device. The first provider edge device encapsulates a multicast packet for the private network multicast group with the address of the public network multicast group. The first provider edge device transmits the encapsulated multicast packet according to the address of the public network multicast group and forwarding information. | 10-03-2013 |
20140314100 | MAC ADDRESS DISTRIBUTION - According to an example, in a method for MAC address distribution by an apparatus, a MAC address is received in the apparatus, in which the apparatus includes a data store on which is stored a local slice set containing a plurality of slices, and in which each of the plurality of slices is assigned a respective slice identifier. An address value for the received MAC address may be determined and a correlation between the determined address value and one of the slice IDs of the plurality of slices may be identified. In addition, the received MAC address may be stored in the slice having the slice identifier identified as being correlated to the determined address value. | 10-23-2014 |
