This development work seeks to meet the performance challenges associated with complex interdependencies, state, and scale in mobile telecommunications networks, without the use of costly special-purpose hardware. Similar to the trend in general data centers, decoupling software functions from the underlying hardware through advances in NFV and Software- Defined Networking (SDN) enhances flexibility, compared to using equipment that is performance-optimized for a specific network function. As demand for telecom services continues its dramatic expansion, infrastructure capacity challenges become more prevalent among Communication Service Providers (CSPs). Transforming carrier networks to take advantage of general-purpose hardware using approaches such as NFV has become a competitive and strategic imperative. At the same time, however, workload characterization and performance measurement for mobile network infrastructure has remained primarily the province of the large manufacturers of special-purpose equipment. Proprietary Key Performance Indicators (KPIs) specific to a single vendor’s equipment have been the industry norm, leaving a gap in terms of identifying workloads and techniques to specify requirements and measure performance on virtualized mobile network infrastructure. This paper represents a step toward developing test workloads and processor, memory, and I/O capacity requirements for transformed mobile carrier networks based on NFV and general-purpose, standards-based Intel® architecture by testing an Evolved Packet
