Abstract
Network resource management and service differentiation according to user requirements and network constraints are crucial elements of the business and operations support systems of any telecommunications operator. These two key capabilities are particularly challenging considering the steady increase in the number of services/applications, their heterogeneous quality of service (QoS) requirements, and the overall traffic that the network has to provide. Service function chaining (SFC) is an enabling technology for the flexible management of specific service/application traffic, providing solutions for classifying flows and enforcing adequate policies along the flow routes according to the service requirements and considering the availability status of the network. SFC is defined as a chain-ordered set of service functions (SFs) that handles the traffic of the delivery (data plane), control, and monitoring (control plane) of a specific service/application.
