Hi all,
What is a "client" in CTP? Is it possible that more than one clients reside
on a single mote?
In "CtpP.nc", the size of the queue of packets to send is defined as:
QUEUE_SIZE = CLIENT_COUNT + FORWARD_COUNT,
and in "CtpForwardingEngineP.nc"
command error_t Send.send[uint8_t client](message_t* msg, uint8_t len) {
......
qe = clientPtrs[client];
qe->msg = msg;
qe->client = client;
qe->retries = MAX_RETRIES;
dbg("Forwarder", "%s: queue entry for %hhu is %hhu deep\n",
__FUNCTION__, client, call SendQueue.size());
if (call SendQueue.enqueue(qe) == SUCCESS) {
if (radioOn && !call RetxmitTimer.isRunning()) {
post sendTask();
}
clientPtrs[client] = NULL;
return SUCCESS;
}
.......
both of which mean there is at most one packet from a client pending to be
sent in the sending queue. Why isn't it possible that more than one packets,
say two, from the same client are waiting in the queue and eventually
transmitted in FIFO order? Thanks.
