CD-JRA-1.3.3 Initial Concepts for Specifying End-to-End Quality Characteristics and Negotiating SLAs

The aim of this deliverable is two-fold. Firstly, it aims at defining the initial concepts for specifying and negotiating end-to-end quality, i.e., a service quality meta-model suitable for the definition and negotiation of service quality specifications and SLAs. The research method for creating this quality meta-model follows a design approach. Initially, requirements are collected dictating the information, structure, and constraints that this meta-model should capture. Then, based on these requirements, the meta-model is designed and finally created. Secondly, this deliverable aims at proposing a methodology for decomposing end-to-end quality into quality specifications for individual SLAs. The research method for achieving this goal follows a hybrid approach: a proof-of-concept and a paper-based approach. In particular, the meta-model’s effectiveness and sufficiency is highlighted by modeling a composite service negotiation scenario and its result, which is a decomposition of end-to-end quality into quality specifications of individual SLAs. Then, initial attempts (materialized in papers of WP members) are provided that address (composite) service negotiation.
