摘要： In general, techniques are described that facilitate scalable wholesale layer two (L2) connectivity between customers and service providers and a demarcation between the L2 wholesale network and one or more ISPs with which customers communicate L2 PDUs. In one example, a network device receives PDU having both a service identifier identifying a service virtual local area network (SVLAN) and a customer identifier identifying a customer VLAN (CVLAN). A virtual switch determines whether an entry of a L2 learning table is associated with both the service identifier and the customer identifier of the PDU. When no such entry exists, a VLAN learning module updates the L2 learning table to create a new entry that maps to a network device interface and is associated with both the service identifier of the PDU and a plurality of customer identifiers that includes the customer identifier of the PDU.

摘要： A network device may receive first qualification indicators, for a first signal, from all line cards of the network device. The network device may, in response to the first qualification indicators, transmit instructions to all of the line cards to use the first signal. The network device may further receive second qualification indicators, for a second signal, from all of the line cards. In response to the second qualification indicators, the network device may store information for the second signal in order to use the second signal as a backup signal.

摘要： Techniques are described for selecting an alternate path for end-to-end service data traffic that traverses multi-homed routers that provide the service to customer networks. For example, as described herein, a router that is a member of a first multi-homing set connected to a layer two (L2) network with one of a plurality of first access links. The router advertises a status of one of the first access links to a second multi-homing set connected to the first multi-homing set with one or more core links. A core link database stores advertised status information for access links of the first and second multi-homing set. Upon a link failure, a path selector selects a core link to transport service data traffic and directs a switch module to switch to active a status a first access links that connects to a router in the first multi-homing set connected to the selected core link.

摘要： Techniques are described that facilitate performing accounting and billing separately for each customer of a service provider account registered to an owner of a shared customer device. An access router performs separate data usage accounting for each of the customers in sub-accounts of the registered service provider account based on customer virtual local area network (CVLAN) and service VLAN (SVLAN) tags included in data packets. A network operator may, therefore, generate a bill for the shared customer device that includes separate data usage charges for each customer. To facilitate the techniques, the access router may determine a CVLAN and SVLAN associated with a customer. The CVLAN and SVLAN tags are included in a service request toward a service provider, and copied into a service request reply toward the shared customer device. The shared customer device then includes the tags in data packets to identify the customer to the access router.

摘要： In general, techniques are described for performing scalable layer two (L2) learning in computer networks. A network device that includes interfaces and a control unit may implement these techniques. The control unit stores a L2 learning table having entries that are each associated with a service tag identifying a service virtual local area network. In response to receiving a packet that includes a service tag, the interfaces access the L2 learning table using the service tag to determine whether any of the entries of the L2 learning table are associated with the service tag. When none of the entries are associated with the service tag, the L2 learning module updates the L2 learning table to create a new entry defining an association between the one of the interfaces that received the packet and the service tag.
