ABSTRACT
With the increasing popularity of handheld devices and wireless lo-
cal area networks (LANs), real-time applications such as Internet
telephony are poised to become ubiquitous. While there has been a
substantial amount of research on quality of service problems in the
Internet, most end-to-end bandwidth allocation approaches, such as
RSVP, have had limited success due to scalability and deployment
issues. Starting with the observation that reserving bandwidth in
the Internet backbone requires substantial infrastructure support,
but reserving bandwidth in the first hop does not, we only focus on
the first-hop reservation. We evaluate several first-hop allocation
schemes and determine their effectiveness in improving end-to-end
performance. Since utilization of the reserved first-hop bandwidth
depends on the remaining Internet path throughput, we character-
