Abstract:
In a network arrangement having an interior network which consists of interior nodes, and is positioned between edge nodes, wherein requests belonging to corresponding data microflows that continually arrive at any interior node do not establish any microflow reservation states, but these requests can establish, maintain and release either a part of, or an entire aggregated reservation state, using a combination of reservation soft state and explicit release principles, a method comprising the steps of:detecting each of said requests arriving at said interior network during a selected time cell in a sequence of time cells; computing a first resource count after said selected time cell, said first count representing the cumulative result of all reserve, maintenance and release requests arriving at said interior network during a first time period defined by a sliding window, said first time period comprising said selected cell and a specified number of additional time cells preceding said selected cell in said time cell sequence; reserving a number of resource units corresponding to said first count for a first reservation period following said selected time cell; sliding said window to define a second time period which includes the time cell next following said selected cell in said sequence, and which excludes the oldest cell of said first time period; and computing a second resource count associated with said second time period for use in reserving resource units for a second reservation period following said first reservation period.
