happy valentines day,
tproxy on wccpv2 L2 vs triangle routing(router mode tproxy)
single cache, gigatbit ethernet. which do you think would get high
req/sec? and smaller overhead.
Well, WCCP is a tunnel. So adds both bandwidth and processing overheads
from the encapsulation/decapsulation. Plus small additional overheads
from the WCCP protocol messages themselves.
triangular/*asymmetric* routing will kill TPROXY. Though I think you
just mean port routing.
On principle and in theory routing is the better one.
As an extra reason, WCCP is IPv4-only. Whereas IPv6 support is one of
the big reasons to move from NAT to TPROXYv4 this year.
