Hi Suman,
I'm afraid not, it would be required that the three-way handshake
happens against one server with TCP traffic and then data is sent.
As such one client must talk to one server for a single ESTABLISHED
TCP connection.
UDP is different, it's stateless so no handshake so you can use
OPS(One Packet Scheduling) to spray packets in a round robin fashion,
another trick with UDP when not using OPS is setting the timeout for
UDP to 1 sec which can give you a pseudo OPS when it's not available.
