Hi All,

Please read the below mentioned details .

Could you please tell me what does
* salFlowService.addFlow(builder.build())    * do

Does it add flows on to my switch ...or some other function needs to be
wriiten to finally send flows on to switch .
What I mean is like for* packet out*
we use

 * TransmitPacketInput input = new TransmitPacketInputBuilder() //*
*                .setPayload(payload) //*
*                .setNode(new NodeRef(egressNodePath)) //*
*                .setEgress(egress) //*
*                .setIngress(ingress) //*
*                .build();*

       and finally to send packet out on to switch we use the below
function

             *   packetProcessingService.transmitPacket*(*input*);  (my
packet reaches switchafter this function)

so in case of *sending flow *

 AddFlowInputBuilder builder = new AddFlowInputBuilder();
                builder.setNode(new NodeRef(nodeInstanceId));
                builder.setVersion(x);
                builder.setType(y);
                builder.setLength(length);
                builder.setXid(0L);
                builder.setVendordata(vendorData);
                builder.setVendorid(1234L);

Now I do
         salFlowService.addFlow(builder.build());

So does it send the flow or it just adds flow ..finally to see flow on to
the switch what do I do ???

I hope my question is clear .If any doubt please do ask.

I am done with packet in and packet out ,now I need to *send flows.*

Regards
Ayushi
