Sorry to have confused you. IB supports the notion of connection over IPv6, not exactly TCP. I just interchanged TCP and notion of connection provided by infiniband. Infiniband is a cluster of technologies like VI, IP, etc. So i felt that we can take advantage of this to do networking. Because the speed of IB ranges from 2.5Gbps to 30Gbps, even a slight overhead in software will affect performance very badly.
