IPTV-Oriented Network Architecture

[EN] Although it emerged as a means to improve switching speed at the core network, MPLS has spread rapidly as a very !exible and robust solution for network providers to enable triple play services and reduce costs at the same time. As network complexity grows and a higher scalability is required to meet customer demands and give them the necessary Quality of Experience, more advanced features and functions must be included at the 'brains' of the network. To this end, a more automated and video delivery oriented path reservation mechanism based on RSVP-TE has been developed and tested in a lab environment with real-world ISP network equipment. We have added additional video intelligence capabilities to the network using Juniper routers and taking advantage of the JUNOS SDK for third-party developers. Finally, some measurements have been taken to validate our IPTV-oriented architecture, showing that it is possible to achieve a reasonably better bandwidth utilization by using the proposed video LSP reservation scheme.The work described in this paper was carried out with the support and network equipment of Juniper Network's Partner Solution Development Platform program.Murcia Olivares, V.; Delgado Calot, AP.; Arce Vila, P.; Guerri Cebollada, JC.
