networking - What is the meaning of “overbuffering” in RUDP? -


http://en.wikipedia.org/wiki/reliable_user_datagram_protocol

in order ensure quality, extends udp means of adding following features:

acknowledgment of received packets

windowing , flow control

retransmission of lost packets

overbuffering (faster real-time streaming)

i recommend reading ietf draft: http://tools.ietf.org/html/draft-ietf-sigtran-reliable-udp-00

the draft not talk mechanism overbuffering. however, rudp maintain explicit account of out-of-order messages , buffer it. receiver uses explicit ack tell sender out of order messages received; call extended ack. tcp not use explicit eack of out-of-order messages reported using sack option.
