Ideal Binary Switch

[Damian Marek]

Attached is an ideal binary switch that works for single sampled optical signals, it uses a very simple comparison calculation to determine whether a signal should be at a top or bottom port. Try out the example OptiSystem project file.

Matlab code follows:

OutputPort1=InputPort1;
OutputPort2=InputPort1;

%Find lengths of vectors

sampledLength = length(InputPort1.Sampled(1).Signal);
seqLength = length(InputPort2.Sequence);

%Repeat elements of bit sequence so vectors match

samplesPerBit = floor(sampledLength/seqLength);
padding = mod(sampledLength,seqLength);
seqMatched=repmat(InputPort2.Sequence’,1,samplesPerBit)’;
seqMatched=seqMatched(:)’;
seqMatched=[seqMatched zeros(1,padding);];

%Find complement of sequence
compseqMatched = ~seqMatched;

%Multiply vectors to produce the outputs
OutputPort1.Sampled(1).Signal = InputPort1.Sampled(1).Signal.*seqMatched;
OutputPort2.Sampled(1).Signal = InputPort1.Sampled(1).Signal.*compseqMatched;

Hi Damian Marek

I am currently working on the Software Defined Optical Network and i need to design an OpenFlow switch in matlab which i have to interface with Optisystem later. Since I had a problem of even generating a stream of packets in optisystem so managed to find a model in simulink for packet communication as u can see in the attached file. From here i can get the syntex of packet headers which i have to compare with the flow entries in the OpenFlow switch yet to be designed in Matlab. I wanted u to check upon if the packet generation mentioned in model below is correct and please suggest how would i be able to analyse the packet headers which i need further. And can i add a Matlab component in simulink as well which would do the job OpenFlow switch of comparing packet headers and taking the required action.
