This doesn't make much sense.  ssh and telnet both run over TCP; TCP 
handles any lost packets.  If you're talking about IPsec, it was 
engineered to make each packet cryptographically independent.  The only 
possible issue is that ssh packets are somewhat longer, thus rendering 
them slightly more expensive to transmit and slightly more liable to 
random bit errors.  But the latter is very unlikely -- you were talking 
about congestion -- and the effect of the former is minimal compared to 
the speed of any likely line.
