Abstract: Techniques for provisioning single or multistage networks using Ethernet Service Instances (ESIs). In one embodiment, an ESI is a logical entity or object that stores information that may be used to provision a network. An ESI may represent a logical entity that identifies a grouping of elements of a network or network device and associated attributes. Hierarchical relationships may be created between ESIs. The hierarchical relationships are used to perform packet-level processing including performing network packet encapsulations.

Abstract: Service providers can reduce multiple overlay networks by creating multiple logical service networks (LSNs) on the same physical or optical fiber network through use of an embodiment of the invention. The LSNs are established by the service provider and can be characterized by traffic type, bandwidth, delay, hop count, guaranteed information rates, and/or restoration priorities. Once established, the LSNs allow the service provider to deliver a variety of services to customers depending on a variety of factors, for example, a customer's traffic specifications. Different traffic specifications are serviced on different LSNs depending on each LSN's characteristics. Such LSNs, once built within a broadband network, can be customized and have its services sold to multiple customers.

Abstract: A system is provided for facilitating assignment of a virtual routing node identifier to a non-routing node. During operation, the system assigns to a non-routing node coupled to a switch a virtual routing node identifier unique to the non-routing node. In addition, the system communicates reachability information corresponding to the virtual routing node identifier to other switches in the network.

Abstract: Congestion control techniques based upon resource utilization information stored by a network device. According to an embodiment of the present invention, a network device is configured to identify a data source causing congestion based upon information stored by the network device identifying a set of data sources, and for each data source, information identifying the amount of a resource of the network device being used for processing data received by the network device from the data source.

Abstract: An exemplary method for circuit emulation over a multi-packet label switching (MPLS) network comprises the steps of receiving a time division multiplexed data stream at an ingress end, dividing the data stream into a set of fixed sized packets, adding a service header to each of the packets, adding an additional header on top of the service header in accordance with MPLS protocols, removing the additional header after each packet has been processed by the MPLS network, and using the service header to recover the data stream at an egress end.

Abstract: Differentiated service classes on a label switch path are managed by comparing at least one packet field value included in a packet of data to mapping field values of a mapping that correlates the mapping field values with queues. The packet is stored into one of the queues based on the comparing. A first subset of the queues is scheduled using a first queue scheduling algorithm and a second subset of the queues is scheduled using a second queue scheduling algorithm. The packet is transmitted onto the label switch path in accordance with a predefined scheduling order of the first subset of the queues and the second subset of the queues.
