$cat /proc/sys/net/ipv4/tcp_adv_win_scale 2 $ Scaling factor for calculating application portion of window. Count buffering overhead as bytes / 2 ^ tcp_adv_win_scale (if tcp_adv_win_scale > 0) or bytes – bytes / 2 ^ (-tcp_adv_win_scale), if it is <= 0. The default value is 2.

The x87 family does not use a directly addressable register set such as the main registers of the x86 processors; instead the x87 registers form a 8-level deep stack structure ranging from st0 to st7, where st0 is the top. x87 is a floating point-related subset (originally an extension) of the x86 architecture instruction set. …
$cat /proc/sys/net/ipv4/tcp_abort_on_overflow 0 $ The tcp_abort_on_overflow variable tells the kernel to reset new connections if the system is currently overflowed with new connection attempts that the daemon(s) can not handle. What this means, is that if the system is overflowed with 1000 large requests in a burst, connections may be reset since we can not …
regedit is the command to invoke registry editor. it can be used for windows TCP tuning. The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components as well as the applications running on the platform: the kernel, device drivers, …
[:–:]cat /proc/sys/net/ipv4/tcp_reordering 3 [:–:] The tcp_reordering variable tells the kernel how much a TCP packet may be reordered in a stream without assuming that the packet was lost somewhere on the way. If the packet is assumed lost, the TCP stack will automatically go back into a slow start since it believes packets may have …
frame —| 1. a border or case for enclosing a picture, mirror, etc. 2. A {data link layer} “packet” which contains the header and trailer information required by the physical medium
echo 1 > /proc/sys/net/ipv4/tcp_abc From RFC 3465. A Modified Algorithm for Increasing the Congestion Window As originally outlined in [Jac88] and specified in [RFC2581], TCP uses two algorithms for increasing the congestion window. During steady-state, TCP uses the Congestion Avoidance algorithm to linearly increase the value of cwnd. At the beginning of a transfer, after …
Certain principles of relativity have been widely assumed in most scientific disciplines. One of the most widespread is the belief that any law of nature should be the same at all times; and scientific investigations generally assume that laws of nature are the same regardless of the person measuring them. These sorts of principles have …
Mechanics is the branch of physics concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effect of the bodies on their environment.
