Abstract

Radio access networks for future LTE/5G scenarios need to be designed so as to satisfy increasingly stringent requirements in terms of overall capacity, individual user performance, flexibility and power efficiency. This is triggering a major shift in the Telcom industry from statically sized, physically provisioned network appliances towards the use of virtualized network functions that can be elastically deployed within a flexible private cloud of network operators. However, a major issue in delivering strong QoS levels is the one to keep in check the temporal interferences among co-located services, as they compete in accessing shared physical resources. In this paper, this problem is tackled by proposing a solution making use of a real-time scheduler with strong temporal isolation guarantees at the OS/kernel level. This allows for the development of a mathematical model linking major parameters of the system configuration and input traffic characterization with the achieved performance and response-time probabilistic distribution. The model is verified through extensive experiments made on Linux on a synthetic benchmark tuned according to data from a real LTE packet processing scenario.
