Hi NANOG,
We often read that the Internet (i.e. BGP) is "slow to converge". But =
how slow
is it really? Do you care anyway? And can we (researchers) do anything =
about it?
Please help us out to find out by answering our short anonymous survey=20=
(<10 minutes).
Survey URL: https://goo.gl/forms/JZd2CK0EFpCk0c272 =
<https://goo.gl/forms/WW7KX5kT45m6UUM82>
** Background:
While existing fast-reroute mechanisms enable sub-second convergence =
upon=20
local outages (planned or not), they do not apply to remote outages =
happening=20
further away from your AS as their detection and protection mechanisms =
only=20
work locally.
Remote outages therefore mandate a "BGP-only" convergence which tends to =
be
slow, as long streams of BGP UPDATEs (containing up to 100,000s of them) =
must
be propagated router-by-router. Our initial measurements indicate that =
it can
take state-of-the-art BGP routers dozens of seconds to process and =
propagate
these large streams of BGP UPDATEs. During this time, traffic for =
important
destinations can be lost.
** This survey:
This survey aims at evaluating the impact of slow BGP convergence on
operational practices. We expect the findings to increase the =
understanding of
the perceived BGP convergence in the Internet, which could then help
researchers to design better fast-reroute mechanisms.
We expect the questionnaire to be filled out by network operators whose =
job relates
to BGP operations. It has a total of 17 questions and should take less =
10 minutes
to answer. The survey and the collected data are anonymous (so please do =
*not*
include information that may help to identify you or your organization).=20=
All questions are optional, so if you don't like a question or don't =
know the answer,
please skip it.
A summary of the aggregate results will be published as a part of a =
scientific
article later this year.
Thank you so much in advance, and we look forward to read your =
responses!
Laurent Vanbever (ETH Z=C3=BCrich, Switzerland)
PS: It goes without saying that we would be also extremely grateful if =
you could
forward this email to any operator you might know who may not read =
NANOG.=
