Hi, I hope you all are doing well! This is Shahrooz, a fourth-year Ph.D. student at the Department of Computer Science at the University of Massachusetts Amherst working under the supervision of prof. Arun Venkataramani. We often read that the Internet (i.e., BGP) has a long convergence delay. But why is it so slow? Moreover, can we (researchers) do anything about it? Please help us out to find out by answering our short anonymous survey (<10 minutes). Background: Measurements on the real Internet show that BGP, the Internet routing protocol, converges slowly upon link or node outages. Convergence delay of BGP can be defined (informally) as the time since a root cause event such as a link or node failure happens until all of the routers affected by that event on the Internet update their best route to a new stable one. According to the operators monitoring convergence time, BGP takes more than 30 seconds to converge upon remote outages, on average. This long convergence delay can result in long data-plane downtime for many destinations, during which packets towards many destinations are lost. During BGP convergence delay, each router will process a newly received route from its neighbors and announce its new best route to that destination to its neighbors. In order to reduce the number of times that a router announces a new route to its neighbors, RFC suggests that routers use a timer called MRAI (Minimum Route Advertisement Interval). After a router has sent an advertisement to a neighbor, it has to wait for at least the MRAI before sending a new route advertisement for the same destination to the same neighbor. The straightforward way to implement the MRAI would be on a per-destination basis, i.e., maintain a separate timer for each destination and each neighbor. However, in practice, usually, it is being implemented per-peer. The default value of MRAI suggested by RFS is 30 seconds. Juniper routers use an out-delay timer instead of an MRAI timer that specifies how long a route must be present in the Junos OS routing table before it is exported to BGP. This survey: This survey aims at finding the best current practices on the Internet about MRAI/"delay out" timer values. In addition, we expect the findings to increase the understanding of the perceived BGP convergence on the Internet, which could help researchers design better solutions for BGP long convergence delay. Survey URL: https://forms.gle/VNRpU2MzRU8DX1o57 We expect the questionnaire to be filled out by network operators whose job relates to BGP operations. It has a total of 6 questions and should take less than 10 minutes to answer. A summary of the aggregate results will be published as a part of a scientific article later (hopefully :) this year. Thank you so much in advance, and we look forward to reading your responses! We would also be extremely grateful if you could forward this email to any operator you might know who may not read RIPE. Best, Shahrooz
