Indigenous Connectivity Summit Participants Share Their Stories

Madeleine Redfern, the mayor of Iqaluit – the largest and only city in Nunavut, Canada – has a colorful way of describing how sparsely populated the territory is. “The seals outnumber the people.” With a population of just over 35,000 people spread out over an arctic 1,750,000 square kilometers, Internet access is a challenge. In fact, according to Redfern, her most favorited tweet was that she couldn’t tweet… because the connection was too slow.

Madeleine Redfern participated in the first ever Indigenous Connectivity Summit last November. She and other participants shared their experience and expertise to help close the connectivity gap in Indigenous communities. Many also sat down for brief interviews with the 1st-Mile Institute, a New Mexico nonprofit that has initiated a local “Broadband for All” program. The videos are now available to watch on the 1st-Mile Institute’s website.

You can also find the videos on the Internet Society’s Indigenet page, which includes resources from the Summit including the presentations, the policy brief Spectrum Approaches for Community Networks, and other ways to get involved!

The DNS Negative Cache

Considering the DNS query chain—

  • A host queries a local recursive server to find out about banana.example
  • The server queries the root server, then recursively the authoritative server, looking for this domain name
  • banana.example does not exist

There are two possible responses in this chain of queries, actually. .example might not exist at all. In this case, the root server will return a server not found error. On the other hand, .example might exist, but banana.example might not exist; in this case, the authoritative server is going to return an NXDOMAIN record indicating the subdomain does not exist.

Assume another hosts, a few moments later, also queries for banana.example. Should the recursive server request the same information all over again for this second query? It will unless it caches the failure of the first query—this is the negative cache. This negative cache reduces load on the overall system, but it can also be considered a bug.

Take, for instance, the case where you set up a new server, assign it banana.example, jump to a host and try to connect to the new server before the new DNS information has been propagated through the system. On Continue reading

Demand for managed SD-WAN services skyrockets

Demand for SD-WAN delivered as a managed service is exploding as customers see the benefits that SD-WAN can bring to their distributed organizations.For example, communications service providers (CSPs) such as Verizon, NTT, and BT all report strong demand for SD-WAN services. Plus, hundreds of other CSPs, cable providers (e.g. Comcast), managed service providers (MSPs), and system integrators have recently deployed new SD-WAN services.Also on Network World: SD-WAN: What is it and why you’ll use it one day | How to make the transition to SD-WAN We also see that managed SD-WAN revenues are growing rapidly as they displace traditional managed WAN services (e.g. private lines and MPLS) — an addressable market of over $40 billion in business services.To read this article in full, please click here

BrandPost: The New SD-WAN Edge Enables Improved Security Architectures

With the beginning of the new year, it’s popular to opine on what the new year might bring in terms of technology advances. My predictions for the WAN in 2018 have been covered in several publications here, here and here. In this blog, I’m going to expand on one of my predictions: how the new WAN edge enables improved security architectures. I believe there are three primary ways the new WAN edge will enable improved security architectures for enterprises building an SD-WAN.To read this article in full, please click here
