Greetings Routing Working Group,
Next week on Friday June 25th at 14:00CEST during TNC (https://tnc21.geant.org/) we will
be holding a Routing Working Group Birds of a Feather (BOF) session. Please find the
abstract and connection information below.
We hope to see you there!

Routing Working Group Co-Chair
Identifying and Addressing R&E Routing Anomalies
14:00 - 15:30 CEST
Adding or removing capacity from the global R&E network infrastructure can have
unexpected routing results that are often difficult to detect and impossible to correct
without coordination. For example, after changes in transatlantic capacity, we see
significant volumes of traffic with both source and destination in Europe traversing
exchange points in the US (traffic from CERN destined for universities in Europe routed
via New York). Similarly, with other additions to transcontinental capacity, we see Asian
traffic destined for Europe routed via the US (often crossing the Pacific twice), and also
traffic with both endpoints in Africa routed via New York. We can identify these anomalous
flows fairly easy with current and expanding tools, such as NetSage
(http://portal.netsage.global) However, due to the number of different organizations
along the international paths, it remains a challenge to bring the right people together
to make adjustments that would potentially correct!
the erroneous paths. This type of routing problem is prevalent, and we expect this issue
is one many NRENs will need to address in order to maintain a robust, reliable, high-speed
global R&E network. With new intercontinental links coming on-line over the past few
years, and more planned for the near future, we believe the time is right for our
community to come together to begin addressing this issue in a more coordinated way. This
BOF will bring together R&E networking engineers in an open community discussion on
how to approach this problem systematically.
