IP Networking
Historically, our group has followed a design philosophy for QoS which suggested that it was feasible, more scalable and more economical to provide QoS by means of an admission control system based on congestion measurements. Additionally this approach was based on sound theoretical basis and economic interpretation. However, throughout the years, we have realised how, in performing the crucial step of going from concept to a real-world solution, our approach needed to be adapted to different scenarios and our design flexed in order to cope with different requirements.
We are at a stage now where most of the requirements provided by the business have been captured and we have sufficient knowledge and expertise to re-visit and finalise our solution for a variety of scenarios. This also involves re-visiting the theoretical foundations of the work, with the purpose of validating them in the light of the newly emerged requirements. This - congestion notification and admission control - is going to be the core of this year's work.
Additionally, we have a number of corollary activities - inter-domain QoS, multi-criteria routing and multi-layer resilience - which complete the core one, providing the missing bits concerning interactions with other admission control systems, with routing protocols, and resilience mechanisms.
Finally, the scenarios, problems, solutions and architectures emerging from this work will be channeled to our internal and external audience, via two roadmapping activities, aimed at positioning our ideas, visions and solutions in a real-world context.
