Even though reads and writes are full duplex, a write cannot proceed until the flush of previous writes has been acknowledged with an HTTP response—a full round-trip is necessary between each flush.
Data Centre TCP DCTCP was designed to provide predictably low queuing latency, near-zero loss, and throughput scalability using explicit congestion notification ECN and an extremely simple marking behaviour on switches. When this happens, New Reno mistakenly enters fast recovery, but when the reordered packet is delivered, ACK sequence-number progress occurs and from there until the end of fast recovery, every bit of sequence-number progress produces a duplicate and needless retransmission that is immediately ACKed.
In when SNA was designed, such redundancy would be prohibitively expensive, or it might have been argued that only the Defense Department could afford it. Furthermore, this approach would work only for HTTP clients.
Psiphon clients authenticate servers using SSH public keys obtained out of band, a process that is bootstrapped with server keys embedded in the client binaries. Our experiences with deploying circumvention systems has led us to conclude that other potential means of censorship—e.

Visitors can test all these claims. Most recent papers first based on date of the first published version. We compare two traffic traces. The Azure columns are estimates of what we would pay if we did not have a special research grant.
While we identify some features that may give a censor leverage in distinguishing circumvention traffic, we believe that the systems we have deployed are sufficiently resistant to the censors of today, and do not block the way to future enhancements to traffic analysis resistance.
We speculate that censors find such tests unattractive because they require storing significant state and are susceptible to misclassification.
Today, however, simple routers cost no more than a PC. This change allows meek-server to distinguish new and existing sessions when a client sends a request after a long delay such as after an Android device awakes from sleepingwhen meek-server may have already expired and discarded its session.
In battlefield conditions, the loss of a node or line is a normal circumstance. TCP treats the data as a stream of bytes.
It has been produced to inform and provide structure to the debate as researchers work towards pre-standardization consensus on this issue. How does the router make a decision between routes? But finally BBR is not the best in all the cases, and we have to deal with 13 different algorithms.
