Coming from the TM WG, we (Raj Jain's group) see that the explicit rate indication can change potentially at every RM cell (send as well as receive). Hence, if the TCP/IP stream doesnt adapt reasonably, source congestion will be more serious than network congestion. By the same token, the source might underload the network even if it has the load to offer if it does not change its sending rate to match the current ACR (available cell rate). -Shiv -- Shivkumar Kalyanaraman (shivkuma@cis.ohio-state.edu) http://www.cis.ohio-state.edu/~shivkuma Office phone : (614)-292-7043 (or 292-7036) Home phone : (614)-299-8634 |
