    MTU

    ! , .
    , () . , , 576 .
    :
    MTU
    Key: Tcpip\Parameters\Interfaces\ID for Adapter
    Value Type: REG_DWORD Number
    Valid Range: 68 - the MTU of the underlying network
    Default: 0xFFFFFFFF
    Description: This parameter overrides the default Maximum Transmission Unit (MTU) for a network interface. The MTU is the maximum packet size in bytes that the transport transmits over the underlying network. The size includes the transport header. An IP datagram can span multiple packets. Values larger than the default value for the underlying network cause the transport to use the network default MTU. Values smaller than 68 cause the transport to use an MTU of 68.

    The TCP/IP standard allows for a receive window up to 65,535 octets in size, which is the maximum value that can be specified in the 16-bit TCP window size field.
    - 64 Window Scale, RFC 1323. Windows registry Tcp1323Opts=1.
