Flow control in distributed gateways
The resultant traffic flows in a preferred direction within a set of cooperative gateway nodes is optimized taking into consideration the internal rate-delay products. The internal rates on directed links among adjacent gateway nodes are included in the set of control variables. It is also shown that the optimal internal rate-delay product of a set of connected gateway nodes can be obtained by locally optimizing in each node the rates of either the input ports or the output ports. The effectiveness of the proposed optimization algorithm is demonstrated for a typical sample gateway of three nodes with inhomogeneous arrival and service rates.
