  • Resource allocation framework for wireless/wired networks
    Patent number: 8351331
    Abstract: A resource allocation framework for wireless/wired networks is described. In an embodiment, methods of end host based traffic management are described which operate separately from the underlying access control protocol within the network (e.g. wireless MAC protocol or TCP). The rate limits for each flow are set based on per-flow weights, which may be user specified, and based on an estimate of the utilization of the shared resource and the rate limits are adjusted periodically so that the resource is not underutilized or saturated. Some embodiments compute a virtual capacity of the resource which is adjusted to optimize the value of the utilization and then the virtual capacity is shared between flows according to the per-flow weights. Methods for estimating the utilization of a wireless network and the capacity of a broadband access link are also described.
