Abstract
A given data unit of a first protocol layer for transmission in a data unit based communication system is passed to a second protocol layer. A numeric value of a numerically quantifiable parameter associated with said given data unit of said first protocol layer is determined and the given data unit is embedded into one or more data units of the second protocol layer and transmission control for the one or more data units of the second protocol layer is performed in accordance with said numeric value of said numerically quantifiable parameter.
Claims17
A method of processing a first data unit of a first protocol layer for transmission in a data unit based communication system, the method comprising the steps of:
- receiving, at a second protocol layer, the first data unit of said first protocol layer, said second protocol layer lying below said first protocol layer;
- performing a buffering operation for said first data unit of said first protocol layer, wherein said first data unit is buffered with a plurality of other buffered data units of said first protocol layer, and
- performing a congestion alleviation procedure for said plurality of buffered data units of said first protocol layer when a predetermined triggering condition is fulfilled, said congestion alleviation procedure comprising:
- a decision step for deciding whether a congestion alleviation measure is to be performed with respect to the first buffered data unit of said first protocol layer, said decision step depending on one or more numeric values that belong to at least one numerically quantifiable parameter associated with the first buffered data unit of said first protocol layer,
- wherein said at least one numerically quantifiable parameter is one of:
- the size of said first buffered data unit of said first protocol layer, and
- an inter-arrival time of data units received from said first protocol layer at the second protocol layer.
