Checksum Offload

[KEiGHT]

According to Microsoft;

*IPChecksumOffloadIPv4 IPv4 Checksum Offload > 0 = Disabled
Why in SG TCP Optimizer is Enabled: 0 ?

registry of Windows says:

"DisableTaskOffload"=dword:00000000

So? Is Enabled or Disabled !?

Why do you mix words ?

*IPChecksumOffloadIPv4 is one of Offload Service Registry Key.
SG TCPO using Global TCP/IP Protocol Registry Key.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\DisableTaskOffload
Setting this value to one disables all of the task offloads from the TCP/IP transport. Setting this value to zero enables all of the task offloads.

Now you see what I am talking about ?



so there must be "enable: 1" and disable: 0

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TCPIP\Parameters\DisableTaskOffload < For Windows 7
*Setting this value to one disables all of the task offloads from the TCP/IP transport. Setting this value to zero enables all of the task offloads.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ipsec\EnabledOffload < For Windows 2000/XP
*Setting this value to zero disables Internet protocol security (IPsec) offloads from the TCP/IP transport. The offloading of TCP/IP checksum tasks, large send offload version 1 (LSOV1),
and large send offload version 2 (LSOV2) are not affected. Setting this value to one enables IPsec offloads.

So there must be Written Enabled Offload or Disable Task Offload , why Checksum Offloading ? Most of the people have no idea what's for and are confused !
