since many
current applications need only bandwidth as a resource.
Because of the analogy between the distributions of the
txaffic within and out ofVPN and the focus ofbandwidth
reservation, authors developed bandwidth guaranteed IP
tunneling router with a lightweight algorithm with the
queues whose sizes are measured for scheduling only with
regard to the number of packets. This paper reports an
evaluation ofthis router using an RTP [5] -based flexible
traflic generatorhnalyzer specially designed to generate
pseudo-traffic in many applications.
