Previous issue date: 2014-07-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / A Internet atual vem sofrendo v?rios problemas em termos de escalabilidade, desempenho,
mobilidade, etc., devido ao vertiginoso incremento no n?mero de usu?rios e o surgimento
de novos servi?os com novas demandas, propiciando assim o nascimento da Internet do
Futuro. 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
