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

RIPE Atlas Probes: Delays in Distribution
Alun Davies — 29 Mar 2018

The good news: RIPE Atlas is growing both in terms of geographical diversity and ASN coverage. What's more, RIPE Atlas is evolving, with a new generation of probe hardware having already passed the test phase and a pilot programme underway to assess the viability of VM anchors. The not so good news: With RIPE Atlas so much in demand, and with our current provider having ceased manufacturing of the probe hardware, we've had to dramatically reduce the number of probes we're distributing.… Read more

OpenIPmap - A Collaborative Approach to Mapping Internet Infrastructure
OpenIPmap - A Collaborative Approach to Mapping Internet Infrastructure
Jasper den Hertog — 14 Feb 2018

OpenIPmap, the RIPE NCC’s tool for geolocating core Internet infrastructure, has undergone a full architectural overhaul. With a new set of APIs and interfaces designed to cater to the needs of all users, the system integrates various methods for estimating the geographical locations of IXPs, core routers and other components of Internet infrastructure. In this, the first of two RIPE Labs articles on the topic, we look at the evolution of OpenIPmap from its inception to today. … Read more
