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.
