Algorithm 1. Automatic protocol adaptation.

Input:  unknown packet: packet Output: matched protocol stack: ps Initialize: PS={ps1,ps2,…,psi,…,pss} //existing protocols stacks      PC={layer1,layer2,…,layeri,…,layerl} //protocol container      Layer = {pi1,pi2,…,pij,…,pip} //deployed protocol in layer i

SendToBus(packet); //send packet to protocol bus    for all protocol stack ps ∈ PS do      if (psi.PsAnalyze(packet)==1){Return psi;} end for      Ps ps=new PS();    for all protocol p ∈ layer1 do      boolean b=TryAnalyze(packet,ps,p,layer1);      if (b==false){Return Null;}      Return ps; end for Procedure TryAnalyze(packet,ps,p,layer) //p is located in layer     payload =p.Analyze(packet);     If (payload==0){       ps.push(p);       Return true;}     layeri = layer.next();     If (layeri == null){Return false;}    For all protocol pi ∈ layeri do     boolean b = TryAnalyze(payload,ps,pi,layeri);     if (b == true){ ps.push(p);}     Return b; end for Procedure End
