I am reading information about VoIP technology For that i am concentrating on SIP (Session Initiation Protocol) and RTP (Real Time Transport Protocol).
I am interested in implementing RTP over TCP I found that there are some disadvantages of TCP, some are1) TCP doesn't support multicasting.
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.3) TCP congestion control mechanism decreases the congestion window when packet losses are detected.
Apart from these flaws i am interested in implementing RTP over TCP
Is it possible ? What is feasibility of implementing RTP over TCP ?
One more point is What is feasibility of implementing RTP over TCP in case of NAT (Network Address Translation) is there ?
Need your valuable suggestion.
Thank You !
