SHReQ: A Framework for Coordinating Application Level QoS @INPROCEEDINGS{ht05, title = {{SHReQ: A Framework for Coordinating Application Level QoS}}, author = {{Dan} {Hirsch} and {Emilio} {Tuosto}}, booktitle = {Proceedings of SEFM 2005, 3rd IEEE International Conference on Software Engineering and Formal Methods}, editor = {K.A. Bernhard and B. Bernhard}, pages = {425--434}, abstract = {We present SHReQ, a formal framework for specifying systems that handle abstract high-level QoS requirements which are becoming more and more important for service oriented computing. SHReQ combines Synchronised Hyperedge Replacement (SHR) with constraint-semirings. SHR is a (hyper)graph rewriting mechanism for modelling evolution of systems. The novelty of the approach relies on the synchronisation mechanism which is based on constraint-semirings, algebraic structures that provide both the mathematics for multi-criteria QoS and the synchronisation policies underlying the SHR mechanism.}, publisher = {IEEE}, year = {2005}, url = {http://www.cs.le.ac.uk/people/et52/LAVORI/shreqsefm05.pdf}, partner = {PISA}, status = {public}, task = {T1.3, T5.1, T5.2}, }
