摘要： Verifying subscriber host connectivity is disclosed. In some embodiments, a unicast address resolution protocol (ARP) request is sent to a subscriber host, and based at least in part on whether a response to the request is received from the subscriber host, it is determined whether the subscriber host remains connected to a network.

摘要： A multilink trunk from a client device in a communication network is split between two aggregation devices such that each aggregation device is connected to at least one link of the multilink trunk. The aggregation devices work in conjunction to appear to the client device as a single device connected to the client device over the multilink trunk. The aggregation devices transmit identical bridge protocol data units to the client device over their respective links of the multilink trunk. The aggregation devices exchange operational information and data packets over inter-device communication ports. A failure of the split multilink trunk at one aggregation device is restored through the other aggregation device.

摘要： Providing network access is disclosed. Use of a provider equipment port via which network access is provided to two or more downstream nodes, each having one or more classes of network traffic associated with it, is scheduled on a per class basis, across the downstream nodes.

摘要： A method and apparatus for providing a Virtual Private Network (VPN) over a connectionless network connecting a plurality of Local Area Networks (LANs), such as an Ethernet network, is disclosed. The method and apparatus comprises associated each VPN with a unique identifier and each LAN of the VPN with a interface device connecting the LAN to the connectionless network, which may be for example, a Synchronous Optical Network (SONET). The interface device may service a plurality of LANs. Accordingly, each LAN is associated with a User-Network Interface that forms part of the interface device. Each data packet destined for a second LAN, such Ethernet frames, received by the interface device for a first LAN is encapsulated with, if known, a Media Access Control (MAC) address of the interface device connected to the second LAN, the VPN's unique identifier, and the port on the interface device connected to the second LAN. Additionally, the corresponding MAC and port address of the first interface device is also used to encapsulate the Ethernet frames. If the MAC and port address is not known (i.e., it is not stored in a database on the first interface device), the first interface device multicasts an encapsulated Ethernet packet to the entire VPN. The first interface device maintains (i.e., updates and appends) its database of MAC and port addresses in response to encapsulated data frames received by the first interface device.

摘要： Managing a network resource is disclosed. An indication that a resource assigned to a subscriber host by a resource allocating node is no longer to be used by the subscriber host is received at a node other than the subscriber host or the resource allocating node. A resource release communication is sent to the resource allocating node from said node other than the subscriber host or the resource allocating node. The resource release communication appears to the resource allocating node to originate from the subscriber host and indicates to the resource allocating node that the resource is no longer to be used by the subscriber host.
