    摘要: In one embodiment, for each port of an access node in an access-based computer network, one access server of a plurality of access servers is configured as a preferred access server for that port. Upon receiving a session initiation message at a particular port, the access node forwards the session initiation message to one or more of the access servers based on the configured preferred access server for the particular port.

    摘要: In one embodiment, a method includes receiving, by an access node, multicast control parameters for white, black, and grey lists of multicast groups. The access node applies the multicast control parameters to an IGMP process running on a port associated with a subscriber. In response to receiving an IGMP message requesting joining a multicast group, the access node either: autonomously forwarding the multicast group on the port where the multicast group in on the white list, blocking the multicast group on the port where the multicast group in on the black list, or relying on a Layer 3 broadband network gateway (BNG) to instruct the access node whether to add a forwarding entry on the port for the multicast group where the multicast group in on the grey list. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

    摘要: Techniques for providing remote access to a service provider network include exchanging multiple Dynamic Host Configuration Protocol (DHCP) formatted messages instead of any Point to Point Protocol (PPP) message to provide all PPP functions for accessing a service provider network from a customer node. The service provider network is on provider premises and the customer node is on customer premises different from the provider premises. The DHCP format is used to exchange authentication messages, user profile data on Authentication, Authorization and Accounting (AAA) servers, or session keep-alive echo messages, alone or in some combination. When all are message types are combined, these techniques provide a remote access server (RAS) with the capability to perform all functions presently provided by PPP processes. In some combinations, these techniques allow a modified DHCP server to replace a legacy AAA server.

    摘要: A method of operation for a node of an Ethernet access network includes issuing a multicast message on the Ethernet access network by a maintenance end point (MEP) of the node. The multicast message contains a name of a target MEP. The node is further operable to receive a unicast reply message from the target MEP, the unicast message reply containing a MEP identifier (MEP-ID) and a MEP Media Access Control (MAC) address of the target MEP. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要: Methods and apparatus for enabling a layer 2 node associated with an open systems interconnection (OSI) reference model to perform resource reservation protocol (RSVP) processing are disclosed. According to one aspect of the present invention a layer 2 device associated with an OSI reference model includes a first interface, a processing arrangement, and a second interface. The first interface intercepts a message associated with a on-path signaling protocol for at least one selected from a group including resource reservation and admission control at a layer above layer 2. The processing arrangement processes the message, and the second interface sends the message.

    摘要: A system includes a multi-stack subscriber, a gateway, and a web portal. The web portal determines whether the subscriber is authenticated to access the Internet using a first Internet Protocol by receiving logon information from the subscriber. The subscriber requests to access the Internet using a second Internet Protocol. The gateway and/or the web portal determine whether the subscriber is authenticated to access the Internet using the second Internet Protocol without sending a second logon to the subscriber.

    摘要: A customer edge device is automatically configured. A request for customer edge device configuration data may be transmitted to a provider edge device via an Ethernet-layer operations, administration, maintenance, and provisioning (OAM&P) protocol. The request for configuration data may be relayed from the Ethernet-layer OAM&P protocol to a configuration protocol. The request for configuration data may be transmitted from the provider edge device to a configuration repository server via the configuration protocol. The configuration repository server may transmit the requested configuration data to the provider edge device via the configuration protocol. The provider edge device may relay the configuration data from the configuration protocol to the Ethernet-layer OAM&P protocol and transmit the configuration data to a customer edge device via the Ethernet-layer OAM&P protocol. The customer edge device may automatically configure itself using the configuration data.
