Abstract: Method and system for adapting access to a packet switching network including a dynamic bandwidth adjustment mechanism which continuously monitors the mean bit rate of the signal source and the loss probability of the connection. These values are filtered to remove noise and then used to test whether the values fall within a pre-defined acceptable adaptation region in the mean bit rate, loss probability plane. Values falling outside of this region trigger bandwidth adaptation procedures which, in turn, result in acquiring a new connection bandwidth, and determining new parameters for the adaptation mechanism.

Abstract: Method and system for adapting access to a packet switching network including a dynamic bandwidth adjustment mechanism which continuously monitors the mean bit rate of the signal source and the loss probability of the connection. These values are filtered to remove noise and then used to test whether the values fall within a pre-defined acceptable adaptation region in the mean bit rate, loss probability plane. Values falling outside of this region trigger bandwidth adaptation procedures which, in turn, result in acquiring a new connection bandwidth, and determining new parameters for the adaptation mechanism. Furthermore, the mechanism controls the number of connections that can be adapted by a single processor, given its processing capability. It ensures fairness between the connections in the sense that it prevents a single connection to use, on the average, a unconsiderate portion of the processor capacity.

Abstract: PROBLEM TO BE SOLVED: To estimate and adjust the band width dynamically for lots of and high speed traffic fluctuation by providing a method that defines an adjustment area and corrects a frequency band width assigned for the connection between a sender node and a destination node in response to a pair of a mean bit transfer speed not set within the adjustment area and a missing rate. SOLUTION: This method includes a process that measures a mean bit transfer speed mn of a signal from a sender node and a process that uses a leakage packet module 107 to control a traffic flow from the sender node to a network, and also includes a process that measures a packet missing rate brought into the network by the packet module 107, a process that defines an adjustment area with respect to measured values of a mean bit transfer speed and a missing rate, and a process that corrects a frequency band width assigned for the connection between the sender node and the destination node in response to the mean bit transfer speed and the missing rate which are not contained in the adjustment area.

Abstract: PROBLEM TO BE SOLVED: To ensure impartiality among all connections supported by a same processor by including processes which measure an average bit transfer speed, control traffic flows, measure a packet missing rate, filter it and request correction of a frequency band width thereby controlling the adjustment of a plurality of connections. SOLUTION: This method includes a process that measures the average bit transfer speed of a signal from a sender node, a process uses a leaked packet control circuit to control a traffic flow from the sender node to the network, a process that measures the missing rate of a packet brought into the network by the leaked packet control circuit, a process filters a missing rate measured value, a correction request process that corrects a frequency band width assigned for connection from the sender node, and a process that corrects a frequency band width of a missing rate measurement low pass filter based thereon.
