The good news on IPv4 address supply'¦


'¦Is that they are expected to run out in exactly 12 months from today, on 14 July 2011. The bad news is a forecast exhaustion date only nine months hence.

According to Kate Lance, communications manager of consultancy IPV6Now, "In exactly 365 days from now, 14 July 2011, all IANA [Internet Assigned Numbers Authority] IPv4 addresses will have been allocated to the regional Internet registries, says APNIC chief scientist Geoff Huston."  [In his IPv4 address depletion counter]


She adds: "Unbelievably, that's the good news. The bad news is that April 2011 is Stephan Lagerholm's IPv4 exhaustion estimate: only 9 months away...

Not that Lance thinks there is much good news at all on the imminent depletion of IPv4 addresses and the transition to their replacement, IPv6, for "any organisation whose business model relies on large numbers of cheap IPv4 addresses."

"Do you think governments will fix this for you?" she asks. "They're too busy trying to catch up themselves. [And] the Internet industry is doing no better. In general it has shamefully lagged behind with IPv6."

Her conclusion: "Large or small business: you're on your own during this amazing transition from IPv4 to IPv6."

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
