Abstract
In multiservice networks, admission control (AC) is a convenient means
of assuring high quality communications by safeguarding enough
availability for customer traffic. This can be particularly useful to
preserve the quality of services such as IP telephony and video
conferencing, and to ensure acceptable throughput to elastic flows.
This paper tackles the problematic of performing implicit AC in
multiservice networks, pointing out a flexible yet simple to deploy
solution for controlling flows which do not explicitly send signaling
admission requests. This allows to complement the explicit AC case,
widening the ability to integrate services and applications in a
transparent way. The versatility and self-adaptability of the proposed
distributed AC criteria in ensuring the quality of multiple services is
also proved.
