. 2.2 Fast retransmission and fast recovery2.2 Fast retransmission and fast recoveryIf the time-out timer set by the sender has arrived but has not yet received confirmation, it is likely that the network is congested, causing the segment to be discarded somewhere in the network. At this point, TCP immediately reduces the congestion window CWnd to 1, and executes the slow start algorithm, while the slow start threshold value ssthresh halved. This is a situation where fast retransmission is not u

value ssthresh halved. This is a situation where fast retransmission is not used.The fast retransmission algorithm first requires the receiving party to issue a duplicate acknowledgment every time a sequence of messages is received (in order for the sender to know earlier that the message segment did not reach the other) and not wait for the sender to confirm the data.After receiving the M1 and M2, the receivers were given confirmation. Now assume that the receiver did not receive

This is a creation in Article, where the information may have evolved or changed. Both make and new are the ways in which the Go language allocates variable memory, where makes primarily targets memory allocations for slice, map and Chan variable types, and the initialization of corresponding internal structures, while new can request any type of variable memory, but when it gets memory, it assigns a value of 0 to slice, The application of map and Chan type variables is not very significant.

"Chinese remainder theorem" is a famous arithmetic work in the period of 5-6 century in China's northern and Southern dynasties, a "matter unknown number" in the book of grandchildren, a solution to the problem: Today there is no know its number, 33 of the remaining two,55 of the remaining three, 77 of the remaining two. Asking for geometry? Answer: 23.According to the above we can get a set of formulas:X≡2 (mod 3)x≡3 (mod 5)X≡2 (mod 7)ThatX% 3 = 2X% 5 = 3X% 7 = 2Then we set X = T1 * A + t2 * b

algorithm.The algorithm calculates the values of f (n), g (n), and H (N), and g (N) calculates the dissipation value of the path from the initial node s to the node n according to the result of the search. and h (N) relies on heuristic information, which is related to the problem and needs to be defined according to the specific problem. Usually called H (N) is the heuristic function, which is to estimate the direction of future expansion.Algorithm A is to arrange the nodes of the open table in

Difference between Debug and Release in Visual Studio, studiodebug In Visual Studio, there are two modes for generating an application: Debug and Release. How can we choose between them?

Using swfupload to upload the $ _ FILES variable is always blankToday, we use HiChina's M3 virtual host, linux system, and apache server. After a program tested locally and other servers is uploaded to the HiChina M3 host, the system prompts that the file cannot be uploaded. After debugging, it is found that the $ _ FILES variable required for file uploading is always blank, therefore, you cannot upload
