- I have sort of grown up with TCP/IP, and I feel comfortable with the notion
- of having sequence numbers on bytes, instead of on packets. I have always
- assumed this was to make the fragmentation/reassembly process easier. (Though
- I notice that XTP version 3.6, which doesn't have fragmentation, still uses
- sequence numbers on bytes - for backwards compatibility?)
-
- Anyway, I'm now facing the possibility of designing another (lightweight)
- transport protocol. (Please don't ask why - we're still in the evaluation
- stages and we *may* end up using an existing protocol). So my question is:
-
- What are the arguments for sequence numbers on bytes instead of packets,
- given that the protocol in question will *not* have fragmentation?
