[c-nsp] OT: Cisco WAAS Setup Scenario

No

Cisco WAAS is also transparent in the sense that accelerator appliances
can use auto-discovery to determine whether a peer accelerator is
available at the other end of the link. After auto-discovery, a pair of
accelerators can auto-negotiate an acceleration policy to be applied to
the application flow. If a peer accelerator is not discovered, the
application flow passes through unchanged.

Hi Team,
Pardon me for the OT.

I want to deploy Cisco WAAS as a proof of concept to a client with
several
sites connected in a hub-n-spoke topology.

I would deploy only one WAE (and a CM) at the hub/head office and one
WAE at
a selected spoke, in production.

I intend on setting the WAEs Inline for simplicity. However, I have some
doubts that I hope you could help clear.

If the WAE at the head office accelerates traffic going to a spoke site
without a WAE, would the traffic be dropped?

If the hub site receives non-accelerated traffic from spoke sites
without
WAE, would the head office WAE drop the traffic?

I am concerned because I know the acceleration process utilizes
compression
schemes which may require decompression at the other site by a WAE.

Labbing this up would give me the answers, but I felt I could leverage
your
skills for quick answers to these :-)

Your responses are appreciated.

Felix
