Title
QoS-Assured Service Composition in Managed Service Overlay Networks
Abstract
Many value-added and content delivery services arebeing offered via service level agreements (SLAs). Theseservices can be interconnected to form a service overlaynetwork (SON) over the Internet. Service composition inSON has emerged as a cost-effective approach to quicklycreating new services. Previous research has addressed thereliability, adaptability, and compatibility issues for composedservices. However, little has been done to managegeneric quality-of-service (QoS) provisioning for composedservices, based on the SLA contracts of individual services.In this paper, we present QUEST, a QoS assUredcomposEable Service infrasTructure, to address the problem.QUEST framework provides: (1) initial service composition,which can compose a qualified service path undermultiple QoS constraints (e.g., response time, availability).If multiple qualified service paths exist, QUEST chooses thebest one according to the load balancing metric; and (2)dynamic service composition, which can dynamically recomposethe service path to quickly recover from serviceoutages and QoS violations. Different from the previouswork, QUEST can simultaneously achieve QoS assurancesand good load balancing in SON.
