Do you mean the taxonomy? (Or am I just totally brain dead today?)

Section 5 of the taxonomy describes inter-replica communication (I
need to go back and see what wording it uses to check that we're
covered for things like "Master Origin Server"), and 3.1.1 describes
client-replica communication.

While I agree that the discussion of CDNs, and the protocols that are
used to distribute content among replicas, is useful, I'm not sure
that this belongs in the taxonomy itself.
