Abstract:
BGP speakers at Internet Exchange Points typically exchange routes
with a large number of peers. To reduce the burden of maintaining
many sessions, IXPs implement and administrate BGP route servers.
Route servers announce to their clients the paths of multiple peers
by using a single eBGP session. Route servers, however, are
restricted to propagating a single path per NLRI per eBGP session.
This constraint affects the diversity of paths received by clients.
To overcome this limitation, we propose the extension of ADD-PATH to
eBGP peers. ADD-PATH allows a BGP speaker to send multiple paths for
the same NLRI, typically through different nexthops, over a single
session with a peer. By supporting ADD-PATH, a route server hence
allows a client to potentially select among all the available paths
for that NLRI, instead of the one arbitrarily chosen by the Route
Server.
