A method for communicating data packets is provided that includes receiving a data packet at a first processor. A packet handle and interface handle are attached to the data packet. The packet handle, interface handle, and data packet are communicated to a second processor. A plurality of data packets that are destined for the same output are multiplexed. At least one packet handle, one interface handle, and the multiplexed data packet are communicated to the first processor, and the multiplexed data packet is output.

A method for selecting an active router in a communication device includes providing multiple routers in the device, coupling the routers to a single physical link, monitoring a status for each of the routers, and selecting one of the routers as an active router by positioning its corresponding relay.

A method for monitoring noise associated with a communication link is provided that includes monitoring a plurality of communication links that facilitate a plurality of communication flows and determining whether an error parameter associated with a selected one or more of the communication links has exceeded a predefined threshold. An alert message may then be communicated to a next destination when the predefined threshold has been exceeded.

A method for selective recovery in a communications environment is provided that includes building a recognizable bit pattern into one or more subframes that are associated with a communication flow. One or more of the subframes may be positioned into a superframe. In cases where one or more errors are present in the superframe, the superframe may be demultiplexed such that one or more of the subframes included in the superframe are analyzed and then discarded or forwarded based on the presence of one or more of the errors.
