A Dynamically Reconfigurable Wireless Sensor Network Testbed for Multiple Routing Protocols

Algorithm 1

Packets process in switch plane.

Input: Payload; FlowTable]; TableLength mask=GetFlowMask(Payload);

offset=GetMatchField(Payload);

for each i TableLength do for each bit in the mask do

   if bit = 1 then

     state=CheckMatchField(offset, FlowTable[i]); if state is true then

       update offset to next match field; end

     else state=false;

       break; end

   end end

  if state is true then

    ExecuteAction(Payload, FlowTable[i]);

    break; end

end

if no action executed then

  ExecuteMiss(Payload); end
