Abstract-- Carrying IP traffic over connection-oriented net-
works requires the use of bandwidth allocation schemes at gate-
ways or network interfaces. A new virtual queue occupancy,
which is more accurate than the classical queue status parame-
ter, is being proposed for periodic bandwidth allocation. Based
on this virtual queue occupancy, an enhanced approach for loss-
less services, referred to as LAVQ, is simulated and evaluated in
an IP/SONET environment. Simulations show that LAVQ out-
performs its counterpart LAQ in terms of bandwidth utilization,
without compromising the performance of queue occupancy.
I. INTRODUCTION
WITH the explosive growth of Internet users, carrying IP
traffic over connection-oriented networks such as ATM
has been intensively studied [1-5]. Moreover, the industry [6-
