Appendix B Deployment Examples
Transparent Local-Listen
The flows from the perspective of the CSS are essentially a combination of what
is expected in transparent and non-transparent modes: the first two flow entries
(client to offloader) look like a non-transparent flow view, and the second two flow
entries (offloader to origin server) look like a transparent flow view. Again, it is
critical to keep in mind that although transparent local-listen is a hybrid proxy,
the model still creates two instances of the client's IP address and must employ
some means of differentiation. This is why even though network address
translation is occurring on the redirection of traffic from the client to the offloader,
ECMP (or some other hashing mechanism) is still necessary for proper routing of
traffic within the offloading triangle.
