Can I use linux stack nodes and ns-3 stack nodes together in one Network (DCE Cradle)

[richard.wi...@gmail.com]

Hi all,

 * I have a network model with 7 nodes all ns-3 TCP/IP.

 * Now I want to install the Linux stack on two of them, to get DCCP support.

Is this possible? Can the nodes communicate with each other?

I've looked through the example and it seems it's either only ns-3 or only Linux stack.

Thanks for the help,

you install the network stack on a node basis so it is possible. I had an experiment running MPTCP linux vs ns3 mptcp.

Hi Matt,

Does ns3 support MPTCP?. I was in an assumption that MPTCP is available only through DCE (MPTCP Linux stack).

If ns3 supports MPTCP, can you please provide some more information on this. 

Thanks

ns3 doesn't have an official mptcp implementation yet but efforts have
been made over the years to provide one, see
https://www.nsnam.org/wiki/Current_Development#Multipath_TCP_for_ns-3.29_and_ns-3.8

Can you please tell me how to create a queue in ns3, I'm a begginner and I don't know anything much about it can you please provide me small code of creating a queue?

Hi Matt,

Thanks for your answer.

I created a hybrid model using ns-3 nodes using tcp as well as dce nodes using DCCP to provide a tunnel for the other nodes.

It turns out the linux DCCP doesn't work when there are ns-3 nodes forwarding the packets in between. The tunnel paths have to be

all-DCE for whatever reason.

However the TCP end nodes using the tunnel can be ns-3 and communicate with the DCE nodes, so maybe it's a DccpSocketFactory specific problem.

However, work well enough for me currently.

Thank you,

Hi Monica,

There are a few MPTCP examples in the ns-3-dce projects examples directory,

maybe they could help you.

Thanks,
