NCP+: An integrated network and IT control plane for cloud computing

摘要: Cloud computing, building on the idea of ''computation as a public utility'' is made possible by increased network capabilities in terms bandwidth and reduced latency. The cloud paradigm today sees adoption many businesses given its advantages, not only from customer point view (e.g., universal access to same applications across all company branches) but also application provider operator perspective software updates no longer need be distributed). To able offer computing services efficiently, service providers just an infrastructure comprising both IT resources, especially control system that orchestrate such integrated services. This paper offers new proposal for system: enhanced plane, NCP+, which based GMPLS plane with Hierarchical Path Computation Element (PCE) architecture jointly make routing server provisioning decisions. Indeed, assumed paradigm, user generally does care what exact offered using, long requirements are met: thus anycast principle applies. discusses (i) (ii) two IT-aware aggregation mechanisms used hierarchical PCE approach (iii) scheduling algorithms those mechanisms. We conclude this work thorough simulation analysis routing/scheduling policies showing Full Mesh where domain topology represented complete graph, although being less scalable computation time, provision efficiently using proposed load balancing policy. However, scenario stringent requirements, Star could parallel scenarios end-to-end setup times important.
