A framework for SLA establishment of virtual networks based on QoS classes

The Internet has become the primary means of communication, where many companies have multiple Internet service providers to establish a Service Level Agreement (SLA). Within this context, this paper shows a framework for virtual networks establishment based on QoS classes, where traffic classification techniques are used to forward the traffic to the provider defined in the SLA. It is expected to ensure QoS requirements for each traffic class, and also to reduce the company costs. The experiments show the capacity of the framework to classify the traffic performing a feasible traffic differentiation according to the defined QoS classes.
