Re: DoS attack ?

YangWoo,

I wouldn't refer to this as a DoS attack, rather as a mechanism for the
(unauthorized) replication (of some or all) of the store.

It may matter that what amounts to an unauthorized zone transfer ties up
the data flow source node, or its local bandwidth, and that these may be
synchronized across multiple sink nodes to fully consume either host cpu
or subnet i/o resource, but that is only one case (discard-at-sinks) of
resource replication.

We see the latter in data mining against whois servers, and I would expect
that resource capture isn't confined to telemarketers mining for telephone
contact data.
