Using mutiple TCP ports with same interface

Hi Matlab Community,

I am facing some issues using the XPC blocks for TCP configure send and receive (Client / Server).

In fact I have a lot of data to transfer with one unique ethernet interface (Speedgoat use). I can configure without any problem the basic Client and Server Model but I am limited to a frame not exceeding 65 504 bytes.

I am currently using UDP protocol because I can choose on which port i am sending the data so I can send the 171 960 bytes I need to exchange between my two models without any problem.

However, TCP is better than UDP so I am slowly migrating into this protocol. But I can't use multiple ports on the same interface and I am not going to use 15 different cables between the two targets...

If you have any idea of how I can solve this issue ... :)

Thanks !

Hi Garbiel,

I believe it's unlikely that this limitation will be lifted in MATLAB R2018b, since no updates are released for this version any longer. But I strongly recommend that you submit a support ticket to the MathWorks to see if this limitation has been lifted in R2020b or more recent. As you might know, a major update was released for Simulink Real-Time in R2020b, which could perhaps be helpful in your case.

Best,

Dimitri
