Network World Public Sup720 Tests Proclaim the Catalyst 6500 “A World Class Winner”
“Our exclusive lab tests show that new line cards and management modules for Cisco's Catalyst 6500 switches push the performance envelope in a number of ways…
• Line-rate throughput with low delay and jitter. The Catalyst becomes only the second product tested to fill a 10G pipe.
• Fast failover. The Catalyst set records for recovery times.
• Perfect prioritization….• IPv6 routing. In the first-ever public test
of IPv6 routing, the Catalyst 6500 moved traffic at line rate even when handling 250 million flows. ”
– Dave Newman
“Simply put, this is the highest-performing 10G Ethernet product we've tested to date.” – Dave Newman

SP Deployment Activities
• Several Market segmentsIX, Transit Carriers, Regional ISP, Wireless/Mobile Operators
• SPs have to get an IPv6 prefix from their Regional Registry, e.g. ARIN
• Today, many trials but few commercial serviceslargely driven by customer demand
• Regional ISP focused on their specific marketsJapan is leading the worldwide commercial deploymentTarget is Home Networking services (dial, DSL, Cable, Ethernet-to-the-Home,…)
• business model evolution to focus on end-point and associated services

Japan Broadband Access ISP Deployment Model
CPEPEISP
Host
ISP provisioning system
The PE can also send RA’s on the PE-CPE link, and the CPE can auto-configure an “uplink” address. Prefix should be different from the prefix assigned to the user.
DHCP ND/DHCPAAA
(1) CPE sends DHCP solicit,
with ORO = PD
(2) PE sends RADIUS request for the user
(3) RADIUS responds with
user’s prefix(es)
(4) PE sends DHCP REPLY,
with Prefix Delegation
options
(5) CPE configures addresses from the prefix on its
downstream interfaces, and sends an RA. O-bit is set to
on.(6) Host configures addresses based on the prefixes received in the RA. As the O-bit is on, it send a DHCP INFORMATION-REQUEST message, with an ORO = DNS
(7) CPE sends a DHCP REPLY containing request options. Note that the CPE is configured as a DHCP client upstream, and as a DHCP server downstream. The DHCP downstream server acts as a cache, and uses the options received on the upstream interface.
