Objectives
MESCAL’s
key objective is: to propose and validate scalable, incremental solutions,
enabling flexible deployment and delivery of inter-domain QoS across
the Internet at large, with the following sub-objectives:
- To develop business
models, based on current commercial practice and emerging business
scenarios, describing the roles of and relationships between the stakeholders
involved in providing QoS-based services across domains.
- To specify a generic,
multi-domain, multi-service functional architecture for the flexible
deployment and delivery of inter-domain QoS-based services.
- To develop templates,
protocols and algorithms for the specification, negotiation, subscription
and invocation of QoS-based IP services between customers and ISPs
and between peer ISPs.
- To enhance existing
inter-domain routing protocols and algorithms and to investigate new
approaches to convey QoS information to enable scalable inter-domain
traffic engineering solutions.
- To examine the
impact of:
- IPv6 on inter-domain
traffic engineering and to ensure that the TE solutions proposed
by the project are applicable to both IPv4 and IPv6 infrastructures.
- both unicast-
and multicast-based services on inter-domain TE.
- inter-domain
aspects of SLS management and TE on corresponding intra-domain
aspects, and vice versa, and to investigate the co-operation required
between them
- To adopt a policy-based
approach to service provisioning and network operation and investigate
policies for SLS negotiation, admission, and inter-domain TE.
- To evaluate and
validate the devised algorithms and protocols through simulation and
testbed prototypes.
- To contribute to
international standardisation efforts, especially the IETF, and to
participate in other consensus-forming activities in the IST programme.
