Abstract: A disclosed method and device relate to defining a link aggregation group (LAG) media access control (MAC) address and assigning the LAG MAC address to two or more links to define a LAG. The LAG MAC address does not duplicate physical MAC addresses associated with the links in the LAG. Datagrams associated with the links in the LAG are routed based on the LAG MAC address.

Abstract: System and method for providing a layer 2 switch in the access network that switches based upon one or more carrier tags identifying customer traffic. Customer traffic conforming to any variety of different layer 1 or layer 2 protocols may be encapsulated and identified according to carrier tag values. The layer 2 switch may determine how to handle the traffic by interpreting and manipulating the carrier tag values. The layer 2 switch may be capable of switching TDM input traffic to either TDM or packet output traffic, and switching packetized input traffic to either TDM or packet output traffic. Handling classification values may also be processed by the layer 2 switch to affect prioritization of handling of encapsulated traffic.

Abstract: System and method for providing applets to remote devices in a communications network. A preferred embodiment includes a host device, which is the device from which the applet will be transferred, and a target device, which is the device to which the applet will be transferred. In one embodiment, the host device autonomously determines that an applet is to be pushed to the target device. The host device then determines the address of the target device and transmits the applet to the target device. Instructions and commands may be sent to the target device form the host, and the target device may transmit results to the host device. In another embodiment, the target device is customer premise equipment and/or a user device that requests an applet from the host device. The target device requests applets, for example, to perform service parameter verification, performance monitoring, troubleshooting, or the like.

Abstract: A device enables a disabled timer state for a link aggregation group (LAG) link if a disabled timer condition is determined for the LAG link, and enables a disabled state for the LAG link if a disabled condition is determined for the LAG link in the disabled timer state.

Abstract: An approach is provided for monitoring and analyzing network traffic. Traffic is monitored during a configurable time interval. A number of bursts associated with the traffic are tracked. A measured traffic rate is generated based on the number of bursts occurring within the time interval. The measured traffic rate is compared with a committed rate to determine if the measured traffic rate exceeds the committed rate.

Abstract: An approach is provided for fault detection and notification for a composite transport group (CTG). A component link of a CTG associated with a label switched path (LSP) is monitored. A fault is detected in the component link. It is determined whether traffic of the LSP can be transparently rerouted to another component link of the CTG based on resource availability of the other component link. The traffic is transparently rerouted to the other component link if resources are available. An upstream label switched node is notified if resources are unavailable.

Abstract: System and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.
