Will 2 applications work simultaneously on one node.

[Jakub Sphinx]

Hello,
I have tried to play around with the Third example from the the tutorials. I have managed to define two interfaces, two channels, two addresses for each node, and assigned different frequencies for each channel.
I know so far that the server can not be installed on the node using the node interface address, while it is possible when I will install client, as illustrated by the example.

 UdpEchoServerHelper echoServer (44);

  ApplicationContainer serverApps = echoServer.Install (wifiStaNodes.Get (0));
  serverApps.Start (Seconds (0.0));
  serverApps.Stop (Seconds (10.0));

  UdpEchoClientHelper echoClient (wifiInterfaces.GetAddress (0), 44);
  echoClient.SetAttribute ("MaxPackets", UintegerValue (10));
  echoClient.SetAttribute ("Interval", TimeValue (Seconds (0.0)));
  echoClient.SetAttribute ("PacketSize", UintegerValue (1024));

Instead, I have tried to install two Servers with different port numbers as the following, but it seems that they do not work simultaneously.

  Ipv4AddressHelper address;

  address.SetBase ("1.1.1.0", "255.255.255.0");
  Ipv4InterfaceContainer wifiInterfaces;
  wifiInterfaces = address.Assign (staDevices);

  address.SetBase ("2.2.2.0", "255.255.255.0");
  Ipv4InterfaceContainer wifiInterfacesx;
  wifiInterfacesx = address.Assign (staDevicesx);

  UdpEchoServerHelper echoServer (44);

  ApplicationContainer serverApps = echoServer.Install (wifiStaNodes.Get (0));
  serverApps.Start (Seconds (0.0));
  serverApps.Stop (Seconds (10.0));

  UdpEchoClientHelper echoClient (wifiInterfaces.GetAddress (0), 44);
  echoClient.SetAttribute ("MaxPackets", UintegerValue (10));
  echoClient.SetAttribute ("Interval", TimeValue (Seconds (0.0)));
  echoClient.SetAttribute ("PacketSize", UintegerValue (1024));

  ApplicationContainer clientApps = echoClient.Install (wifiStaNodes.Get (nWifi-1));
  clientApps.Start (Seconds (0.0));
  clientApps.Stop (Seconds (10.0));

  UdpEchoServerHelper echoServerx (55);

  ApplicationContainer serverAppsx = echoServerx.Install (wifiStaNodes.Get (0));
  serverApps.Start (Seconds (0.0));
  serverApps.Stop (Seconds (10.0));

  UdpEchoClientHelper echoClientx (wifiInterfacesx.GetAddress (0), 55);
  echoClientx.SetAttribute ("MaxPackets", UintegerValue (10));
  echoClientx.SetAttribute ("Interval", TimeValue (Seconds (0.0)));
  echoClientx.SetAttribute ("PacketSize", UintegerValue (1024));

  ApplicationContainer clientAppsx = echoClientx.Install (wifiStaNodes.Get (nWifi-1));
  clientAppsx.Start (Seconds (0.0));
  clientAppsx.Stop (Seconds (10.0));

Could anybody please comment on this

Regards
Jakub

Hi,

short and simple: you can install and use as many applications as you want on a single node. They'll all work together (provided that there's no collision on opening sockets and ports.

I must also point out a couple of imprecisions (for the sake of future readers).

You say "the server can not be installed on the node using the node interface address, while it is possible when I will install client"

This is not true.

The UdpEchoServer does not contain an address to be blinded to. I.e., it will reply to any UDP packet incoming on the specified port, regardless of the address.

This (of course) doesn't mind that you can't define a server bound to a specific address or interface... it's only a limitation of the UdpEchoServer.

Moreover, also for the client this is incorrect. You specify the destination address in the client, not the source address. The client will use the normal IP routing to decide the outgoing interface (and the source address).

This was the introduction.

The main body is: you could have found a bug, or you could have found a patched bug.

Without the full script and without knowing what version of ns-3 you're using, no conclusion is possible.

As a side note, I hope you're not using a version older than 3.21 (we're at 3.22 and working toward 3.23).

Hi,

two bad ideas:

  echoClient.SetAttribute ("Interval", TimeValue (Seconds (0.0)));

This will make the client send all its data at the same time. This will flood the ARP cache (the node still needs to probe for the next hop MAC address) and packets will be dropped.

Use a more logical interval.

  clientApps.Start (Seconds (0.0));
  clientApps.Stop (Seconds (10.0));

Have the client start after and stop before the server. Otherwise it could start sending packets before the server is ready (the opposite for the stop).

Cheers,

T.

[Jakub Sphinx]

Thank you. Well appreciated help

[Jakub Sphinx]

One Last concern please regarding this, I have changed the time Interval and made the both Servers starting one second in advance, following the examples.

Should not I expect to receive packet on the both interfaces of the client at the same time, Why I am still having delay, I expected to have two physically seperated interfaces.

At time 1s client sent 1024 bytes to 1.1.1.1 port 44
At time 1s client sent 1024 bytes to 2.2.2.1 port 55
At time 1.00817s server received 1024 bytes from 1.1.1.2 port 49153
At time 1.00817s server sent 1024 bytes to 1.1.1.2 port 49153
At time 1.0103s server received 1024 bytes from 2.2.2.2 port 49154
At time 1.0103s server sent 1024 bytes to 2.2.2.2 port 49154
At time 1.01331s client received 1024 bytes from 1.1.1.1 port 44
At time 1.02144s client received 1024 bytes from 2.2.2.1 port 55

​

[Jakub]

Sorry for being buggy here, but I am trying to understand a fundamental issue regarding Redundancy.

When I am sending more than one packet, there is no delay in receiving  any packet after the first one, but there is always presented delay with the first packet arrival? Do I miss something here ?

Thank you'r comments.

At time 1s client sent 1024 bytes to 1.1.1.1 port 44
At time 1s client sent 1024 bytes to 2.2.2.1 port 55
At time 1.00817s server received 1024 bytes from 1.1.1.2 port 49153
At time 1.00817s server sent 1024 bytes to 1.1.1.2 port 49153
At time 1.0103s server received 1024 bytes from 2.2.2.2 port 49154
At time 1.0103s server sent 1024 bytes to 2.2.2.2 port 49154

At time 1.01331s client received 1024 bytes from 1.1.1.1 port 44    --------------- 1st Packet reception delay on the two interfaces ??
At time 1.02144s client received 1024 bytes from 2.2.2.1 port 55
At time 2s client sent 1024 bytes to 1.1.1.1 port 44
At time 2s client sent 1024 bytes to 2.2.2.1 port 55
At time 2.0015s server received 1024 bytes from 1.1.1.2 port 49153
At time 2.0015s server sent 1024 bytes to 1.1.1.2 port 49153
At time 2.0015s server received 1024 bytes from 2.2.2.2 port 49154
At time 2.0015s server sent 1024 bytes to 2.2.2.2 port 49154
At time 2.00324s client received 1024 bytes from 1.1.1.1 port 44    ---------------No Delay for the second Packet
At time 2.00324s client received 1024 bytes from 2.2.2.1 port 55

[Tommaso Pecorella]

One word: random number generators.

The interfaces have random parts (e.g., the random backoff), so it's normal to have slightly different results.

This is the most plausible explanation. However, on my computer (0.1 sec interval, apps starting at 0.1) all is synchronous.

As a consequence, I'd suggets to check the pcap files to be sure of what's happening (i.e., that the packets are sent on the right channels).

Cheers,

T.

I hope it will be useful for future NS-3 beginners, when tackling the fundamental issues, it seems that port creation require about 8 ms in my case, and this is presented in the 1st packet reception, as soon as the time interval for echoClient is larger than 8 ms, nothing will be observed with the second reception.

If the interval in the both clients are set to be less than 8 ms such as

  echoClient.SetAttribute ("Interval", TimeValue (MilliSeconds (1.0)));

​

The delay is accumulated over every reception.

Thank you Tommaso.

...

[Tommaso Pecorella]

Not really... 8ms is the time needed to perform the ARP resolution :)

The port are created right away, but the first packet will trigger an ARP resolution (two indeed, one for the client, one for the server).

If the interval is too short, the packets will be queued until the ARP is finished. And they could be discarded too (the ARP queue is limited).

Never underestimate the ARP...

T.

[Jakub]

Thank you Tommaso for the clarification. It's the explanation try from who does not know anything about Address resolution involvement here, its always great to  know new things.

Jakub

Don't worry. The first time I met ARP effect I was puzzled too.

Sir, I am also facing same issue. I have two interfaces. One is 802.11n(10.0.0.0) and 802.11ac(192.168.0.0). When I am sending packets between 192.168.0.0 network's nodes they are received from 10.0.0.0. I am really struggling to this part. I will really appreicate your help sir.
