stor-serv: Adding Quality-of-Service to Network Storage
Coshall John, I-Hsun Chuang, Marvin A. Sirbu · 1999
Network caching, while robust and adaptive, can only be considered a best-effort network storage service. Cache misses introduce significant variations in data access times, and this may be unacceptable to some applications that require consistently fast access to their data objects. The stor-serv framework, inspired by the intserv and diffserv frameworks in the data transmission domain, brings the concept of Quality-of-Service (QoS) to the network storage domain. The framework supports multiple service classes, each with varying degrees of QoS, to cater to the requirements of different applications.
