Uncovering Remote Peering at IXPs
Uncovering Remote Peering at IXPs
Vasileios Giotsas — 12 Dec 2018

Internet Exchange Points (IXPs) originally aimed to keep local traffic local and reduce dependence on third parties. However, ever-increasing traffic volumes create pressure for denser and more diverse peering that challenges the traditional IXP model. A fundamental shift in peering practices is Remote Peering (RP): networks may establish remote or indirect peering connections at IXPs, either over a ‘long cable’ (owned or leased) or over resellers that provide both IXP ports and Layer-2 access. RP has fired up a heated debate within the operators’ community about its effects on Internet economics, resilience and performance. Currently, we lack the tools to identify remote members and the implications of RP. To bridge this gap, we developed and tested a methodology to accurately identify RP, aiming to enable a more transparent peering ecosystem.… Read more

Now in article form, here's what I had to say about the status of the IETF standards for DNS over TLS (DoT) and DNS over HTTPS (DoH) as well as the deployment status of clients and servers for those technologies.… Read more

When the Internet Goes Down: Tracking Edge Outages at Scale
When the Internet Goes Down: Tracking Edge Outages at Scale
Philipp Richter — 30 Nov 2018

Uninterrupted availability of the Internet has become increasingly critical these days, not just for end users but also for service providers who need to meet Service Level Agreements (SLAs). Yet, outages affecting end-user connectivity are widespread, whether they be unintentional fibre cuts, natural disasters, cyber attacks, or intended Internet shutdowns by governments for political reasons.… Read more

Twelve Steps to Enable IPv6 in Government and Enterprise Networks
Twelve Steps to Enable IPv6 in Government and Enterprise Networks
Jordi Palet Martinez — 23 Nov 2018

In the first part of this two-part series, I shared a recent IPv6 deployment case study I worked on for a government network in the LACNIC region, concentrating on the hereditary peculiarities in the network that we had to overcome, many of which are common among government and organisational networks worldwide. This second post is a quick guide to the necessary steps such networks will face during an IPv6 deployment project.… Read more
