Connectivity Services Management in Multi-Domain Content-Aware Networks for Multimedia Applications
This paper proposes a new framework, for connectivity services management in overlay Virtual Content Aware Networks (VCAN) built over multi-domain, multi-provider IP networks. The framework is part of a Future Internet-oriented Multimedia networked architecture developed inside a FP7 European ICT research project, ALICANTE. The VCAN new concept is a stronger coupling between network and applications. The VCANs are managed by CAN Providers, and the high level services by Service Providers (SP). The CANP offers to SPs enhanced connectivity services, including unicast, multicast, in a multi-domain networking context. The management framework is based on vertical and horizontal Service Level Agreements(SLA) negotiated and concluded between providers and possibly also on content/service description information (metadata) inserted in the media flow packets by the servers.
