The concept is called fractals where you can compress the image and send the
values and recreate the image. There was a body of work on the subject, I
would say in the mid to late eighties where two Georgia Tech professors
started a company doing it.

Andrew,
Earlier this week I had a meeting with the ex-Director of the Network
Operations Center for MFS-Datanet/MCI whose tenure was through 1999. From 1994
to 1998 they were re-architeching the Frame Relay and ATM networks to handle
the growth in traffic including these new facilities called
Some pseudo random thoughts and questions? (my BGP is rusty.)
1. Does it violate your AUP with APNIC?
2. If the larger routing prefix is from APNIC will your upstream in the EMEA
region filter or black hole the sub prefix since it is from APNIC and not RIPE
and would appear to be a hijacked
What is all this talk about AC. Real data centers use DC.

Jason,
Fore was purchased by Marconi who sold me the Fore ASX switches for a broadband
access network in 2001. Ericsson still seems to be selling ASX and TNX boxes.
Do you have access to an ATM protocol anlyzers with the port type and speeds
you are running?

Michael,
From my work in access networks they are:
IPv6 native support for:
Routed Access - Ethernet or Wireless, global prefix under the main or dot1Q isl
encapsulated sub-interfaces.
For DSL and ATM PVCs routed RFC 2684 encapsulation with a different IPv6 prefix
for each one of the PVCs.
for fuller
deployment of IPv6 to residential customers.

Mike,
Your latencies which suddenly appear for several hours and then go away and do
this on a regular basis sounds like a layer 2, facility switching issue. As
you indicated the problem comes on during the day and then lets up late in
the evening sounds like the under lying facility is
of the
lengthening delay and what other activity event would correlate with it.
