MESCAL aims to propose and validate scalable, incremental solutions that enable the flexible deployment and delivery of inter-domain Quality of Service (QoS) across the Internet. This involves developing: templates, protocols and algorithms for establishing Service Level Specifications (SLS) between Internet Service Providers (ISP) and their customers, including their peers; scalable solutions for inter-domain Traffic Engineering (TE) based on enhancements to the existing Border Gateway Protocol (BGP) routing protocol and associated route selection logic. MESCAL will consider both unicast- and multicast-based services and ensure that the proposed solutions are applicable to both IPv4 and IPv6.
MESCAL views two major aspects as essential to the deployment and delivery of inter-domain QoS-based IP services: the definition of QoS-based connectivity services to be provided by stakeholders; and second, the means to engineer network resources to meet agreed performance and capacity targets for the contracted services. Together, these two dimensions aim at providing the means for a dynamically configurable Internet, with service requirements driving traffic engineering to meet end-to-end service demands.
