Re: Common operational misconceptions

Right, asymmetric paths are the norm for many inter-provider
communications.
A related misconception is that asymmetric paths are problematic.
Another mis-conception related to path is that more (visible) hops are bad
with the corollary that routers introduce (significant) latency.
Of course, propagation delay is the most significant contributor to latency
in WAN environments (or serialization delay for low-speed links).
