Okay,

I was researching an arcane fact on the theoretical and practical sizes for RTP packet sizes for video conferencing.

What I have come up with is: There is specific RFC's about implimenting H.263, H.261, G.723, but I'm looking for just an overall practical size to check input buffer sizes.

RFC 1889 RTP packet structure referes to 768, RFC 791 RFC 768 UDP refers to obsolete RFC 760. RFC 791 states in the Glossory, ARPANET messages max size is about 1012 octets (8096)bits. ARPANET packet max size is about 126 octets (1008) bits.

As a client side EP, should I be concerned about the ARPANET message size or the ARPANET packet size?

RFC 760 states: 65,536 octets theoretically, put not practical Page 22, every destination should be able to receive a datagram of 576 octets in one piece or as fragments to be reassembled

so my guess here is 4608 bits max? Or is this too low level and there is another RFC that I should reference?

Any help in this direction?

Thanks,
