TDM transport of packets is no longer economically viable, lacks statistical multiplexing which makes it very expensive

Full transformation to NGN needs to occur from core to customer

Long term vision is critical, this will be the network for the next decade

What is the most effective technology choice that will:

Minimize CapEx and OpEx?

Provide carrier class service delivery?

Maximize service agility?

Carriers want the deterministic attributes of transport networks with the flexibility of the internet

RIR Pool

IANA Pool

Feb 3, 2011

*

May 3, 2012

Where do IP addresses come from?

• IANA (ICANN) used to give blocks to RIR’s

• RIR gives allocations to LIR’s

• LIR is typically an ISP, Enterprise, University

• W6L: Turn it on, leave it on.

Since 6/6/12, IPv6 becomes part of a regular business!

• Who will turn on IPv6 and AAAA forever?

Google & Youtube, Facebook, Yahoo!, Akamai, Microsoft Bing, AOL, Netflix, VK…

CPE vendors – Cisco/Linksys, D-Link
