Ativa Pro comes
complete with everything you need to optimize and
enhance your internet connection speed and improve
PC to ISP reliability. What makes Ativa Pro
extraordinary is its built in DUN Tweaker which
provides the ultimate in Dial Up Networking
configurability.
Optimizing Dial-Up Modem
Connection Speed
By optimizing the
MaxMTU & MaxMSS settings, together with the RWIN
and TTL settings you can increase dialup modem
connection reliability and performance by as much as
200%.
What is the MTU
and MSS?
MTU stands for
Maximum Transmission Unit and
it defines the maximum size of a packet that can be
transferred in one frame over a network.
MSS or Maximum
Segment Size defines how much actual
data can put in that packet, and it should be a
slightly smaller value than MTU to allow for packet
addressing and other information.
Why do the
default values need to be changed?
By default Windows
hardcodes the value of MTU to equal 1500 bytes. This
value is adequate for normal LAN networking, but
when you're connecting to the Internet with a modem
this value is too high. This can show itself in
different ways, the most noticeable affect is less
than peak performance.
By adjusting this
value to more closely match the requirements of a
modem Internet connection, major performance gains
can be achieved.
Optimizing
the DefaultRcvWindow & DefaultTTL Settings
The optimization of RcvWindow and DefaultTTL,
together with the other registry settings - MaxMTU
and MaxMSS can speed up TCP/IP modem networking
connections (eg. Internet connections).
RWIN
(Receive WINdow) is the buffer your
machine waits to fill with data before attending to
whatever other TCP transactions are occurring on the
other threads and sockets WinSock has open while a
connection is in progress.
TTL
(Time To Live) defines how long
a packet can stay active before being discarded. The
default value is '32'
