Abstract
We study possible Service Level Agreement (SLA) objectives corresponding
network service availability in packet switched networks, focusing on IP
networks. Service availability is looked from ISO-OSI reference model layers
and cross-layer point of view. Both IETF and ITU-T metrics and definitions are
discussed. We define IP network service availability, briefly IPavailability,
as a set of metrics and consider the feasibility to measure these metrics.
Regarding to a possible SLA, we also consider whether it is possible to affect
or control a given single domain network in such a way that the performance
regarding to an individual metric is improved.
