Abstract: A method of operation for a provider edge device of a core network includes receiving a customer frame from an access network; the customer frame having a first Virtual Local Area Network (VLAN) tag of a first predetermined bit length. The first VLAN tag including a service instance identifier. The service instance identifier of the first VLAN tag is then mapped into a second VLAN tag of a second predetermined bit length greater than the first predetermined bit length. 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. 37 CFR 1.72(b).

Abstract: Apparatus and method of detecting a fault in a network service includes an Ethernet access network domain in which a heartbeat message is broadcast at a periodic interval by each of a plurality of edge devices associated with an instance of the network service. Each of the edge devices also receives the heartbeat messages broadcast at the periodic interval from other edge devices. A fault occurrence is identified when the edge device fails to receive an expected heartbeat message at the periodic interval from one of the other edge devices.

Abstract: In one embodiment, a method associated with a multiple I-service registration protocol (MIRP) includes receiving into an 802.1ah I-component an MVRP TCN from an 802.1ad component. The TCN may be received, for example, from an 802.1ad bridge. The TCN may identify an affected service using an S-VID. Therefore, the example method may include identifying the S-VID specified by the TCN. The method may also include identifying I-SIDs related to the S-VID. The I-SIDs may be identified by consulting an S-VID to I-SID translation table associated with the 802.1ah I-component. The method may also include providing an 802.1ah MIRP PDU to another 802.1ah component. The MIRP PDU may be based on the MVRP TCN and on the I-SID.

Abstract: A broadband access node includes a port for connection with a Digital Subscriber Line and a processor to run code that implements a virtual maintenance end point (vMEP). The vMEP translates an IEEE 802.1ag Loopback Message (LBM) received from a device on an Ethernet access network into a legacy operations and maintenance (OAM) message that is transmitted to a residential gateway (RG) device. The legacy OAM message determines a link-level connectivity status between broadband access node and the RG device. The vMEP also transmits a reply message back to the device on an Ethernet access network in compliance with the IEEE 802.1ag specification. 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. 37 CFR 1.72(b).

Abstract: In one embodiment, a network device may participate in an election process to elect one of two or more Provider Edge devices of a Redundancy Group to be a Designated Forwarder for the Redundancy Group, where the Redundancy Group is in a Service Provider network, and where the Redundancy Group serves a Customer Edge device of a customer network. The network device may forward multi-destination traffic to the Customer Edge device according to whether the network device is elected to be the Designated Forwarder for the Redundancy Group. Multi-destination traffic may include multicast traffic, broadcast traffic, or destination unknown unicast traffic.
