Abstract: A bandwidth manager sets a target packet loss probability under the assumption that the channel is perfect. A real-time estimation of an effective probability of packet loss caused by collisions (605) is then determined by filtering out statistics relating to packet loss probability that exceeds the target packet loss probability. The probability of packet loss caused by channel impairments (607) is computed after the estimates of both the load-specific packet loss probability and an overall packet loss probability is estimated. The channel quality (609) is then estimated in terms of the impairment-specific packet loss probability by considering the overhead due to retransmissions of lost packets caused by channel impairments.

Abstract: Disclosed is a method for aggregating parallel data links connecting two end-point devices into a logical link. If one of the parallel data links is a multi-point link, then an end-point device can still access that link to route traffic to an end station on the link (that is, to a device other than the other end-point device of the logical data link). In the terminology of this disclosure, the logical aggregated link is accessed through an "aggregated port" on an end-point device, while the constituent multi-point link is accessed directly through a "singleton port." By assigning a smaller cost to the aggregated port than to the singleton port, embodiments avoid creating routing loops. In some embodiments, the aggregation is performed at Layer 2 of the Open System Interconnection seven-layer protocol model. Then, the methods of the present invention work well with existing IEEE 802.1 bridging architectures and protocols.
