Abstract
This thesis examines Internet Small Computer System Interface (iSCSI) storage architecture and introduces a framework to furnish Quality of Service (QoS) for the qualified storage traffic. The framework incorporates IO scheduler that does priority scheduling for desired IO request and receives higher degree of service in its journey through the network by adopting Differentiated Services (DS) network architecture with each node exhibiting Expedited Forwarding (EF) behavior. In this thesis, to achieve end-to-end QoS for the application, a novel functional module is introduced in storage server to provision QoS for the requested data and the proposed framework is examined subsequently with an analytical model to estimate the maximum delay bound. The results derived in the analytical model are compared with the available experimental results in the literature. The distinct implication of the proposed framework is in achieving its objectives of guaranteed transmission of data with deterministic maximum delay, without modifying existing structural components and network protocol semantics.
