  In the context of Border Gateway Protocol (BGP), inbound inter-domain traffic
engineering (TE) remains a difficult problem without panacea. Each of
previously investigated method solves a part of the problem. In this study, we
try to complement the map by exploring the use of BGP communities. With BGP
community based polices enabled in transit provider networks, we are able to
manipulate incoming traffic for stub Autonomous System (AS) in a finer
granularity than known techniques by customizing the AS-paths perceived by
remote networks. We analyze the constraints using this technique, along with
its effectiveness and granularity.
