![]() Our contributions include: (1) a faster algorithm for obtaining optimal service tiers (2) a new formulation and optimal algorithm to optimize jointly the number and magnitude of each service tier and (3) the concept of ?TDM emulation? in which all service tiers are multiples of the same (software-configurable) bandwidth unit, and a suite of algorithms to select jointly the basic unit and service tiers. In this work, we study a number of problem variants related to service tier selection. Such a service has the potential to simplify a wide range of core network functions, allowing the providers to scale their operations efficiently. ![]() Many network operators offer some type of tiered service, in which users may select only from a small set of service levels (tiers).
