Performance Analysis of Multipath BGP
Multipath BGP (M-BGP) allows a BGP router to install multiple 'equally-good'
paths, via parallel inter-domain border links, to a destination prefix. M-BGP
differs from the multipath routing techniques in many ways, e.g. M-BGP is only
implemented at border routers of Autonomous Systems (ASes); and while it shares
traffic to different IP addresses in a destination prefix via different border
links, any traffic to a given destination IP always follows the same border
link. Recently we studied Looking Glass data and reported the wide deployment
of M-BGP in the Internet; in particular, Hurricane Electric (AS6939) has
implemented over 1,000 cases of M-BGP to hundreds of its peering ASes.
In this paper, we analyzed the performance of M-BGP. We used RIPE Atlas to
send traceroute probes to a series of destination prefixes through Hurricane
Electric's border routers implemented with M-BGP. We examined the distribution
of Round Trip Time to each probed IP address in a destination prefix and their
variation during the measurement. We observed that the deployment of M-BGP can
guarantee stable routing between ASes and enhance a network's resilience to
traffic changes. Our work provides insights into the unique characteristics of
M-BGP as an effective technique for load balancing.Comment: IEEE Global Internet (GI) Symposium 202
