Witryna26 sie 2024 · TCP New-Reno (1999) [RFC 6582], obsoletes [RFC 3782] New-Reno improves retransmissions compared to TCP Reno during fast recovery. New-Reno is able to detect multiple lost packets. The only problem with this algorithm mistakes some TCP reordering by more than 3 sequence numbers. WitrynaRFC 1323 [ JBB92 ] suggests that TCP connections utilizing large congestion windows should take many RTT samples per window of data to avoid aliasing effects in the estimated RTT. A TCP implementation MUST take at least one RTT measurement per RTT (unless that is not possible per Karn's algorithm).
RFC 6582 - The NewReno Modification to TCP
Witryna24 lut 2014 · RFC 1323 presents a set of TCP extensions to improve performance over high-bandwidth paths. Among other things, it defines a new TCP option carrying two four-byte timestamp fields. The first one is the current value of the timestamp clock of the TCP sending the option while the second one is the most recent timestamp received from … WitrynaRFC-1072 defined a new TCP "SACK" option to send a selective acknowledgment. However, there are important technical issues to be worked out concerning both the format and semantics of the SACK option. Therefore, SACK has been omitted from this package of extensions.

You can send multiple packets by way of HTTP persistent connections, where:... WitrynaThe user is now writing data to TCP in 512 byte blocks as fast as TCP will accept them. The user's first write to TCP will start things going; our first datagram will be 512+40 bytes or 552 bytes long. The user's second write to TCP will not cause a send but will cause the block to be buffered. barbara gaines bx ny
