In today's telecommunication industry, a grand challenge faced by many network service providers (NSPs) is how to cost-effectively allocate resources so as to agilely accommodate a variety of applications and services with diverse quality-of-service (QoS) requirements. To address this challenge, a promising technology is network slicing, with which tenants, can create different network slices with desired performance guarantees on the same network infrastructure. In the past three years, network slicing has attracted significant attention from academia and industry. However, most existing studies have focused on how to dynamically partition a physical network infrastructure into many network slices, and thus assumed that each tenant knows the right amount of resources which is necessary to accommodate certain traffic load with performance guarantees. This assumption causes a gap between tenants and NSPs, which compromises the adoption of network slicing. In this talk, we first introduce how to model the relationship among traffic load, resource, and performance. With this model, given the traffic load and desired performance, we can derive the amount of resource to be provisioned. We then introduce a network tomography based approach to infer a set of interested paths with the minimum number of monitors.
