User-oriented QoS-provisioning is a major problem in enterprises that run a huge number of applications using a computer network. Current approaches that try to improve the level of QoS provided by a computer network just focus on the compliance with technical aspects of QoS. The user-experience and also business objectives, which depend on business processes and the dynamic behavior of the user,...
Guaranteed, high-quality service in the computer network often requires a single reserved path. However, a single path can easily suffer from single point failures. This paper provides a solution to handle flows when their reserved primary paths fail. The solution pairs a reserved primary path with an unreserved backup path. When a failure occurs and a primary path fails, the initial service guarantee...
In order to preserve quality of service (QoS) in a computer network, implementation of traffic engineering (TE) techniques is critical to meet congestion control. In this paper a systematic control strategy based on discrete time sliding mode control considering the dynamics of the window based TCP flow is proposed. Robustness of the designed controller against disturbance and delay variations has...
