Over the years the Internet has become the main means of communication, where many companies and organizations use Internet as basis for its services, and in most cases, these companies have multiple Internet service providers (Multi-Provider Model). However, the current Internet does not provide guarantees of Quality of Service (QoS). To overcome this problem, companies define a Service Level Agreement (SLA), which must be applied between all the providers that are part of the end-to-end path. Within this context, this PHD project aims to develop an architecture for end-to-end SLA negotiation and management of virtualized network based on QoS classes. The negotiation process would deploy the virtual network with the desired characteristics for all the domains until you reach the desired target area. Besides the process of negotiating the architecture aims to enable the renegotiation of the SLA parameters on the fly. The validation of the proposal will be made through the emulator Mininet, which creates networks based on OpenFlow protocol. It is expected satisfy the QoS requirements of each traffic class defined, while reducing costs for companies.
