Transformation - the Real Business Case for NFV and SDN

2016 has seen a steady flow of announcements on successful Network Functions Virtualization (NFV) Proof-of-Concept deployments, mostly focused on virtualizing Customer Premise Equipment (vCPE). This has been a relatively straight forward starting point because unlike many other NFV applications, the vCPE use case does not involve complex activities like having to scale in or out individual services. more

Is the Internet Fragmenting? Join the Discussion Live - Tuesday, May 10, at 3:30pm US EDT

Is the global, open Internet moving away from a network of networks that is universally accessible to a series of networks fragmented along policy, technical or economic lines? As some governments pass laws related to data localization and restriction of cross-border data flows, what will the impact be? What about the increasing use of DNS and content filtering? What other factors have the potential for causing fragmentation? more

Declaring IPv6 an Internet Standard

I've already shared my thoughts following a session of the IPv4 Sunset Working Group at IETF 95 that considered whether to declare IPv4 an "Historic" specification. Of course, as one would expect for a meeting of a Standards Development Organization (SDO), that wasn't the only standards process discussion through the week. Another session, this time in the IPv6 Maintenance Working Group, considered the related topic of whether to make the IPv6 specification a full Internet Standard. Let's look at that proposal. more

Declaring IPv4 “Historic”

At the IETF 95 meeting at the start of April, I was in a meeting of the IPv4 Sunset Working Group, and heard Lee Howard, Director of Network Technology at Time Warner Cable, present on a proposal that recommended that IP version 4, or to be specific, that the technical protocol specification documented in RFC 791, be declared "Historic"... The rationale for this proposed re-designation of IPv4 was that this protocol has indeed been superseded by a more recent specification, namely IP version 6. more

IPv4 Market Outlook

When 2015 began, there were several million IPv4 numbers still in the American Registry for Internet Numbers (ARIN) IPv4 free pool, ARIN was processing 4-5 unique IPv4 transfer transactions per month, and fewer than 5 million numbers had been transferred publicly in the prior 12 months. The end of 2015 told a different story. In late September, the ARIN free pool was depleted. more

Reflections on NANOG 66

The North American Network Operators Group (NANOG) continues to be one of the major gatherings on network operators and admins, together with the folk who work to meet the various needs of this community. Their program committee produces a program that never fails to provide thought provoking interest. Here are my reactions to some of the presentations I heard at NANOG 66, held in San Diego in February. more

Thoughts on the Open Internet - Part 6: Final Thoughts

Today we just don't have an "Open" Internet. The massive proliferation of network-based middleware has resulted in an internet that has few remaining open apertures. Most of the time the packet you send is not precisely the packet I receive, and all too often if you deviate from a very narrowly set of technical constraints within this packet, then the packet you send is the packet I will never receive. more

Thoughts on the Open Internet - Part 3: Local Filtering and Blocking

The public policy objectives in the area of content filtering and blocking space are intended to fulfil certain public policy objectives by preventing users within a country from accessing certain online content. The motives for such public policies vary from a desire to uphold societal values through to concessions made to copyright holders to deter the circulation of unauthorised redistribution of content. more
