    摘要: The present invention provides a method and system for estimating the optimum service rate or bandwidth requirement (BWR) for a switch or router in a communications network for a particular traffic flow which contains elastic traffic, i.e. traffic subject to a feedback mechanism. The invention provides an iterative technique to estimate the optimum service rate from calculated BWRs for the particular traffic flow without initially knowing the precise form of the BWR for various service rates at a buffer of a switch. This is done by initially configuring a service capacity, calculating the BWR to configure a new service capacity and repeating this until the calculated BWR and configured service capacity coincide.

    摘要: A apparatus for use in assisting a person in getting into or out of bed, adjusting position on a bed, or performing exercises on a bed. The apparatus comprises a sheet having one or more grasp able fabric handles situated in convenient positions which can be grasped by a person needing assistance in adjusting position, exercising, or entering or exiting a bed. The apparatus is secured firmly to a mattress be means of straps affixed on its bottom surface, so that stress caused by the use of the handles will not dislodge it from the bed.
