Research

My major research areas of interest are as follows:

Service-based Architecture

The solutions developed in the H2020 POINT and RIFE project have been further developed into a service-based architecture (SBA) platform with full ETSI NFV compliant orchestration of control and user plane services. In the H2020 FLAME project, we embed this platform into a future media internet delivery platform, together with advanced monitoring and control capabilities developed by IT Innovation. Trials and showcase efforts aim at developing use cases on future media delivery with user-facing delivery in smart city environments deployed in Bristol and Barcelona. We also deploy the platform in the UK-funded 5G Smart Tourism project with a final delivery planned for March 2019. The technologies developed for this platform are disseminated into standard organisations such as the IETF or 3GPP.

Flexible Service Routing

After joining InterDigital Europe in London in 2013, I started working on solutions that apply my work on information-centric networking in the context of flexible (service) routing. Within the EU-funded H2020 project POINT, we are currently developing solutions for IP/HTTP-level flexible routing. These solutions provide significant performance benefits for operators deploying this solution in their networks, particularly SDN-enabled ones. This work is complemented by efforts within the H2020 project RIFE, where we develop solutions that lower costs of provisioning Internet access, striving for universal Internet access for everybody. In the two projects, I have been acting as Technical Manager (POINT) and architecture leader (RIFE), leading a small team at InterDigital towards developing and building the solutions designed within these projects.

Architectures and Technologies for the Future Internet

Since leaving BT Research in 2009, I focussed on Internet architecture related issues during my work at Cambridge University. The activities were a mix of technical but also community-related work.

Seamless and Context-aware Services

After joining Nokia Research in 2000, I started my work in the area of seamless and context-aware services. This topic comprises aspects to provide protocol and service functionality in a multi-dimensional heterogeneity, i.e., in the presence of heterogeneous access networks across operators and device boundaries. It further considers the adaptation of service and application functionality based on the currentcontext of the user. Context includes, but is not limited to, information about location, presence, current activity, affective state, or other information of the user.
