Gerenciamento Dinâmico de Qualidade de Serviço em Redes OBS Baseadas no GMPLS

Fernando Nazareno Nascimento FariasRafael Pereira EstevesAntônio Jorge Gomes Abelém

This paper presents a proposal to dynamically control the Quality of Service (QoS) in optical networks based on optical burst switching (OBS) which use a GMPLS control plane. In this proposal, monitoring agents are used to verify the quality of service experienced by the burst classes and to deploy reactive mechanisms in order to guarantee absolute performance levels and, through GMPLS traffic engineering, offer idle resources to traffic flows whose service level is not being achieved. Simulation results show that the proposal can minimize the blocking probability when there are violations of burst flows parameters.
