Abstract:
A method for allocating transmission resources to a constant rate connection, comprising:determining a maximum cell clumping value for a constant rate connection based on a peak cell rate and a cell delay variation tolerance for the constant rate connection; determining an allocation bandwidth for the constant rate connection based on the maximum cell clumping value, the allocation bandwidth comprising a bandwidth at which no cells of the constant rate connection are lost and the cell delay variation tolerance for the constant rate connection is satisfied; and wherein the determining the allocation bandwidth for the constant rate connection comprises: determining a maximum allowed cell queuing delay based on an end-to-end delay requirement for the constant rate connection; comparing the maximum allowed cell queuing delay to the cell delay variation tolerance; determining the allocation bandwidth to be the peak cell rate in response to the maximum allowed cell queuing delay being greater than or equal to the cell delay variation tolerance; and determining the allocation bandwidth to be greater than the peak cell rate in response to the maximum allowed cell queuing delay being less than the cell delay variation tolerance; and allocating the allocation bandwidth at a network element for transmission of the constant rate connection.
