preventing timeouts on slow TCP-based VPN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




 Hi,

  I'm using a TCP connection which carries SSL-wrapped PPP stream to make
a VPN. (let's call this "the primary TCP connection")

  Now there is (by nature, nothing that can be fixed) a big packet loss on
the physical media carrying the primary TCP connection, so the TCP has
timeouts, say, 15% of the time. However, since the underlying PPP that's
being carried in turn carries other "secondary TCP connections", the
secondary TCP connections then time out *much more*. ( It seems it's
something like a square function of timeouts of the primary TCP
connection. )

 The Question :

  How can I tell the TCP stack for the PPP interface that media for the
PPP connection is SLOW (because the primary TCP times out often) but
LOSSLESS (since it *is* a TCP conection which guarrantees delivery), *so
that the PPP TCP stack prevents timeouts and never resends a packet* ?!


   Thx,

     JV
