Abstract
With the spread of survivable network the existing quality of service (QoS) classes are required to be expanded with service availability and maintainability issues. By including them in the service level agreements (SLAs) new and more complex requirements of commercial applications can be guaranteed. In this paper, a uniform framework of extending all types of QoS definitions with service availability characterization is proposed, and a new concept called quality of resilience (QoR) is defined. In addition, all service QoR parameters are expressed using the downtime probability density function and its derivatives. The new QoR factors meet the requirements of users, and the feasibility concerns of operators, which is illustrated by evaluating and comparing various resilience schemes in terms of the QoR framework
