I found that there are some disadvantages of TCP, some are

1) TCP doesn't support multicasting.


I think multicasting is done by IP, not TCP.

2) Through TCP is reliable, it heavily depends on retransmission of

lost or corrupted packets. That increases Delay. Our aim is real

time delivery of packets not reliability.


Why not use UDP then ?

3) TCP congestion control mechanism decreases the congestion window

when packet losses are detected.


What are the other options ?


Apart from these flaws i am interested in implementing RTP over TCP

Is it possible ? What is feasibility of implementing RTP over TCP ?


AFAIK, RTP is a transport like protocol for real-time audio video data. What is the advantage of implementing it over TCP ?
