Novas propostas sobre redes orientadas a conte?do, como a arquitetura Entidade Titulo (ETArch), proveem novos servi?os para este tipo de cen?rios, implementados sobre o paradigma de redes definidas por software. Contudo, o modelo de transporte do ETArch ? equivalente ao modelo best-effort da Internet atual, e vem limitando a confiabilidade das suas comunica??es. Neste trabalho, ETArch ? redesenhado seguindo o paradigma do sobreaprovisionamento de recursos para conseguir uma aloca??o de recursos avan?ada integrada com OpenFlow. Como resultado, o framework SMART (Suporte de Sess?es M?veis com Alta Demanda de Recursos de Transporte), permite que a rede defina semanticamente os requisitos qualitativos das sess?es para assim gerenciar o controle de Qualidade de Servi?o visando manter a melhor Qualidade de Experi?ncia poss?vel. A avalia??o do planos de dados e de controle teve lugar na plataforma de testes na ilha do projeto OFELIA, mostrando o suporte de aplica??es m?veis multim?dia com alta demanda de recursos de transporte com QoS e QoE garantidos atrav?s de um esquema de sinaliza??o restrito em compara??o com o ETArch legado / Current Internet has confronted quite a few problems in terms of network mobility, quality, scalability, performance, etc., mainly due to the rapid increase of the number of endusers and various new service demands, requiring new solutions to support future usage scenarios. New Future Internet approaches targeting Information Centric Networking, such as the Entity Title Architecture (ETArch), provide new services and optimizations for these scenarios, using novel mechanisms leveraging the Software Defined Networking (SDN) concept. However, ETArch approach is equivalent to the Best Effort capability of current Internet, which limits achieving reliable communications. In this work, ETArch was evolved with both quality-oriented mobility and resilience functions following the over-provisioning paradigm to achieve advanced network resource allocation integrated with OpenFlow. The resulting framework, called Support of Mobile Sessions with High Transport Network Resource Demand (SMART), allows the network to semantically define the quality requirements of each session to drive network Quality of Service control seeking to keep best Quality of Experience. The SMART evaluation in both data and control plane was carried out using a real testbed of the OFELIA Brazilian island, showing that its quality-oriented network functions allowed supporting bandwidth-intensive multimedia applications with high QoS and QoE over time through a signalling restricted scheme in comparison with the legacy ETArch
