Securing the Critical Internet Infrastructure is an ongoing challenge for operators that require collaboration across administrative boundaries. A lot of attention has been given in recent years to securing the Domain Name System through a technology called DNSSEC. However, in the last couple of years, the attention has shifted to the security of the Internet routing system and the best practices adopted by network operators around the globe in this area. The main questions these efforts are trying to answer are: is your network authorised to use resources such as IP addresses? Do my packets travel through the advertised path or are diverted on their way? These problem statements may sound too technical for the audience but in reality they can quickly be converted in real business impact. Unauthorised claiming of network resources are proven to cause downtime not only for one web server but to complete networks. Particularly, imagine a phishing attack where the IP address, the domain name and the TLS certificate are legitimate but you just interacting with the wrong network. The hijack of IP addresses is normally due to bad operational practices (basically miss-configurations that leak to the global Internet) but it is also suspicious of playing a role in SPAM and other sensitive areas in security.

In the blink of an eye, a Hotspot 2.0 industry milestone was achieved last week. Cisco joined with China Mobile and 15 other operators to provide a Next Generation Hotspot (NGH) Experience to over 400 attendees at the WBA Wi-Fi Global Congress in Beijing.
The NGH Experience included: Read More »

I recently had the honor to speak at the Wi-Fi Global Congress in Beijing. As evident by the more than 400 people in attendance, the importance and relevance of Wi-Fi continues to grow. The Wireless Broadband Alliance now has over 100 members, a doubling in less than 2 years. The membership includes a mix of leading Wi-Fi, mobile, and broadband network operators; global service providers and media players; as well as technology providers and partners.
I took away six key messages from this exciting conference:
- Next Generation Hotspots is Alive and Well. One of the most exciting things at the conference was the launch of the live NGH Experience with China Mobile as the host operator and Cisco as the network infrastructure provider. Attendees with a Samsung Galaxy or iPhone 5 could experience the first ever opportunity to seamlessly and automatically connect to the venue Wi-Fi. Participants also received valuable conference information and services seamlessly delivered to their mobile device through NGH. This is just the beginning. With 15 major carriers (and growing) signed up to deploy NGH, mobile users throughout the world will be able to experience the next generation of Wi-Fi early in 2014.
- Wi-Fi Roaming is Becoming a Reality. Several speakers described roaming as being where cellular roaming was 15 to 20 years ago. However, with the successful launch and upcoming deployment of NGH, seamless roaming amongst carriers is now becoming a reality. Indeed, the GSM Association recently approved a Wi-Fi Roaming Annex that will make it easy for mobile operators to support this. As such, the WBA expects roaming to be fully automated across more than 80% of public Wi-Fi networks by 2018.
- Wi-Fi is an Important Part of the Mobile Network. The world’s largest mobile operator, Read More »

“Software is Eating the World” is a quote attributed to Marc Andreessen and somewhat further explored by his business partner Ben Horowitz. Mark Andreessen gives compelling reasons to validate this quote. To some extend I have to agree with some of his reasons (but I am also a little bit biased as a software engineer). On the other hand, when I read this (and this is partly based on working in different domains on software), I wonder if software is that disruptive? If you look “under the hood” of software applications, you find that a lot of software is based on fundamental software principles that are already 20-30 years old, yet Read More »

This was the title of a November 19 2013 panel that I had moderated in Washington D.C. at the MPLS-SDN Isocore Conference.
The abstract for this conference was designed to be a bit provocative, specifically:
“ Virtualization as a concept is not new. However, in the context of Software Defined Networking,the virtualization discussion has been focusing on overlay functions e.g networking. What about virtualization overlays and interworking with existing architectures? What are the implications to performance and management? Are we speaking the same language?
The panelists will have an opportunity to articulate the virtualization problem space for the industry and the opportunity for the industry to address.”
My panelists included the following individuals: Read More »
