摘要： In general techniques are described for applying differentiated services with a customer-aware network device. A network device comprising a control unit and an interface may implement the techniques. The interface receives a network packet that is associated with first and second labels. The first label uniquely identifies a Cable Modem Termination System (CMTS) within a plurality of CMTSs. The second label uniquely identifies one of a plurality of CPE devices coupled to the CMTS. The control unit determines at least one subscriber-specific service associated with the one of the plurality of CPE devices based at least in part on the first and second labels associated with the labeled network packet. The at least one subscriber-specific service comprises a service associated with the one of the plurality of CPE devices. The control unit applies the at least one subscriber-specific service to the labeled network packet received from the CMTS.

摘要： In general, techniques are described for transmitting MPLS labels over a network. More specifically, a network device such a router receives a packet to be forwarded according to a label switching protocol, such as Multi-Protocol Label Switching (MPLS). The router may determine a service instance for the packet based on a client device from which the packet originated. The network device may determine one or more services to apply to the packet based on the service instance for the packet and generate a label which having a service instance portion and a service information portion. The network device may append the label to the packet to form an MPLS-encapsulated packet, and may forward the MPLS-encapsulated packet via an output interface according to the label switching protocol.

摘要： In general, techniques are described for providing feedback loops for service engineered paths. A service node comprising an interface and a control unit may implement the techniques. The interface receives traffic via a path configured within a network to direct the traffic from an ingress network device of the path to the service node. The control unit applies one or more services to the traffic received via the path and generates service-specific information related to the application of the one or more services to the traffic. The interface then sends the service-specific information to at least one network device configured to forward the traffic via the path so that the at least one network device configured to forward the traffic via the path is able to adapt the path based on the service-specific information.

摘要： In general, techniques are described for extending routing protocol advertisements to include respective attributes of constituent links of an aggregation group. In one example, a network device includes a management interface that receives configuration information that specifies first and second constituent links for a layer two (L2) aggregated interface. The first and second constituent links are physical links connected to respective physical interfaces of forwarding units of the network device. A routing protocol daemon of the control unit generates a link state message that specifies layer three (L3) routing information associated with the aggregated interface and further specifies an attribute of the first constituent link and an attribute of the second constituent link. The routing protocol daemon sends the link state message from the network device to another network device of the network in accordance with a routing protocol.

摘要： Routers balance network traffic among multiple paths through a network according to an amount of bandwidth that can be sent on an outgoing interface computed for each of the paths. For example, a router receives a link bandwidth for network links that are positioned between the first router and a second router of the network, and selects a plurality of forwarding paths from the first router to the second router. Upon determining that one of the network links is shared by multiple of the plurality of forwarding paths, the router computes a path bandwidth for each of the plurality of outgoing interfaces so as to account for splitting of link bandwidth of the shared network link across the multiple forwarding paths that share the network link. The router assigns packet flows to the forwarding paths based at least on the computed amount of bandwidth for each of the outgoing interfaces.
