We present a new method for selecting between replicated servers distributed over the Internet. First, we introduce a novel utility framework that factors in quality of service metrics. Then we design an optimization algorithm, solvable in polynomial time, to allocate user requests to servers based on utility while satisfying network transit cost constraints, mapping service names to service instance locators. We then describe an efficient, low overhead distributed model which only requires knowledge of a fraction of the data required by the global optimization formulation. Next, a load-balancing variant of the algorithm is explored that substantially reduces blocking caused by congested servers. Extensive simulations show that our method is scalable and leads to higher user utility compared with mapping user requests to the closest service replica, while meeting network traffic cost constraints. We discuss several options for real-world deployment that require no changes to end-systems based on either the use of SDN controllers or extensions to the current DNS system. date: 2018-02 publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC official_url: http://dx.doi.org/10.1109/TNET.2017.2780257 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1514288 doi: 10.1109/TNET.2017.2780257 lyricists_name: Griffin, David lyricists_name: Phan, Truong lyricists_name: Rio, Miguel lyricists_id: DPGRI47 lyricists_id: TKPHA06 lyricists_id: MJGRI50 actors_name: Phan, Truong actors_id: TKPHA06 actors_role: owner full_text_status: public publication: IEEE/ACM Transactions on Networking volume: 26 number: 1 pagerange: 245-258 pages: 14 issn: 1063-6692 citation: Truong, KP; Griffin, D; Maini, E; Rio, M; (2018) Utility-Centric Networking: Balancing Transit Costs With Quality of Experience.
