Abstract:
The Internet is composed of many separate
administrative domains called Autonomous Systems (ASs).
To enable the end-to-end Quality of Service (QoS) for
Internet applications, the inter-autonomous system QoS
routing plays an important role in advertising the
available network resources between domains. In this
paper, Border Gateway Protocol (BGP) is extended to
provide end-to-end QoS. The choice of using BGP is due
to 2 reasons: (1) BGP is currently the only inter-domain
routing protocol activated on the Internet. (2) The use of
attributes attached to routes makes BGP powerful and
scalable inter-domain routing protocol. This paper
introduces an extension to BGP to support multi-domain
feature for our new FICC-Diffserv architecture, which
was introduced in an earlier work [1]. Via simulation
results, we demonstrate the performance of the BGPextended
architecture, including route selection policy and
overhead reduction issues. The paper concludes by
highlighting some directions for future research.
