sockets - Simulate a continuous client-server communication in ns3 -


i want simulate simple continuous client-server request-response behaviour; i.e. client sends packet server, server receives packet , responds client, client receives response packet , again sends out new packet server , on. have figured out send 1 round of communication (client->server->client) don't know how continue this. code achieve 1 round:

udpechoserverhelper echoserver (9);  applicationcontainer serverapps = echoserver.install (wifiapnode.get (nwifiap - 1)); serverapps.start (seconds (1.0)); serverapps.stop (seconds (10.0));  udpechoclienthelper echoclient (apdevicesinterfaces.getaddress (nwifiap - 1), 9); echoclient.setattribute ("maxpackets", uintegervalue (1)); echoclient.setattribute ("interval", timevalue (seconds (1.0))); echoclient.setattribute ("packetsize", uintegervalue (1024));  applicationcontainer clientapps;  clientapps = echoclient.install (wifistanodes.get (nwifista - 1)); clientapps.start (seconds (2.0)); clientapps.stop (seconds (10.0));

if set other int 1 in echoclient.setattribute ("maxpackets", uintegervalue (1));, able have many rounds problem start @ 1 second gap (due this: echoclient.setattribute ("interval", timevalue (seconds (1.0)));). want client starts sending out receives response server , not after waiting 1 second.

you need modify echoclient application , in particularly 'handleread' method respnsible reception of packets. prints 1 received. take @ udpechoserver application, handleread generating response.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
