IPv6… Canada About to Score?

USA-Canada World Championship hockey games never fail to elicit great excitement. In the IPv6 adoption world league however, the US seems to have a convincing lead over their northern neighbour but the game is not over yet, here come the Canucks. Internet evolution, and IPv6 in particular, were the major themes at the ISACC (ICT Standards Advisory Council of Canada) Plenary meeting in Ottawa mid April... more

The Cybersecurity Act of 2009

Four senators (Rockefeller, Bayh, Nelson, and Snowe) have recently introduced S.773, the Cybersecurity Act of 2009. While there are some good parts to the bill, many of the substantive provisions are poorly thought out at best. The bill attempts to solve non-problems, and to assume that research results can be commanded into being by virtue of an act of Congress. Beyond that, there are parts of the bill whose purpose is mysterious, or whose content bears no relation to its title. more

Traffic Management: An Undefined Term

In Europe yet another package is discussed, and it includes issues related to what I guess one could call Network Neutrality. And, as usual, at the end of the game, texts are negotiated that does not have much meaning in reality. Negotiations on what words imply, while I as an engineer have absolutely no idea what either of the parties actually mean... more

Will ENUM Deliver?

ENUM (E.164 NUmber Mapping) is a technology that has been around for a little while that has promised much and, so far, delivered little to the average user. As Nominet has recently been awarded the contract to administer the UK 4.4.e164.arpa delegation, I thought it was time that I put my thoughts on this subject down in writing. I'm going to cover the potential of ENUM in the telecoms industry and what it could mean to you, along with how it is currently being used and what potential security issues surround ENUM. more

Designing Secure Networks with Cisco Technology, Part 4

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 3 of this series I began to discuss Cisco technologies as a standard for enterprise data security. In this article we take a look at how Cisco firewall and packet filtering technologies can be used at the network perimeter to enhance enterprise security. more

DPI is Not a Four-Letter Word!

As founder and CTO of Ellacoya Networks, a pioneer in Deep Packet Inspection (DPI), and now having spent the last year at Arbor Networks, a pioneer in network-based security, I have witnessed first hand the evolution of DPI. It has evolved from a niche traffic management technology to an integrated service delivery platform. Once relegated to the dark corners of the central office, DPI has become the network element that enables subscriber opt-in for new services, transparency of traffic usage and quotas, fairness during peak busy hours and protection from denial of service attacks, all the while protecting and maintaining the privacy of broadband users. Yet, DPI still gets a bad rap... more

WiMAX vs. LTE

Mobile WiMAX, with the release of 2×2 MIMO chips in 2008, gives WiMAX a lead of two or so years on its major competitor -- the 3GPP's LTE. However, 3G cellphones using 3GPP UMTS technologies, extended to higher speeds with HSPA, is widely used in handsets in many countries. In North America, 3GPP2 CDMA2000 and EV-DO are widely used, but these are likely to be replaced over time by LTE and to some extent WiMAX. more

More Cracks Appearing in Mobile Market

When I wrote the BuddeComm analysis on the introduction of Apple's iPhone I commented that the most significant element of this event was that it would begin to create cracks in the flawed business models of the mobile operators, who are desperately hanging on to their closed networks very much like the fixed operators were fighting tooth and nail against opening up their networks. We have seen that the fixed operators have largely lost this battle and we predict that the future of the mobile networks will be no different... more

The Slow Mainstreaming of IPv6

Slowly, we’re making progress mainstreaming IPv6. I wanted to post on a few interesting developments. Late last month, Netflix got an IPv6 allocation from ARIN, and they’re advertising it in BGP... I look forward to the day I can stream movies to my Netflix set-top box over IPv6. more

A Seismic Shift: IPv4 Numbers Becoming Transferable and Consequently Property

A Tipping Point for the Internet? Catching the precise moment of a tectonic shift in a global system as large and important as the Internet may be viewed as an exercise in the improbable. However, I point out in this summary that I think we are precisely in the midst of such a shift... more
