Question

I have two interfaces in a solaris host. I would like to initiate two TCP connections to a single TCP server via both interfaces as shown in the diagram. Are there any options in Java to bind the interface to the TCP socket to override the local routing table?

I am attaching the network diagram,

I would like to use both the serial links bandwidth to get the data from server. Hence I would like to initiate the connection on both the interfaces.

thanks,

You can use

Socket s = new Socket(hostname, port, localInterface, 0);

However, many OSes do not honour this “hint” and will use the routing table anyway.
