A kutatási téma leírása:

Research objectives:
Network routing is the aspect of network engineering dealing with mapping user traffic to the network infrastructure, so that data is delivered to the destinations in a reliable and timely fashion. It encompasses a wide array of topics, including large-scale routing and packet forwarding architectures and algorithms, failure localization and recovery, traffic engineering and resource optimization, the design and implementation of fast switch/router dataplanes and general packet classifiers, etc. The aim of the research under this Proposal is to improve our understanding of, and to gain new practical and theoretical insights into, the intrinsics of modern packet routed telecommunications networks.

Open problems:
- Design, analysis, and evaluation of programmable data-plane devices. Today's software-defined networks depend on a reconfigurable data-plane whose functionality can be modified online, through an open and standardized control protocol. This topic includes all aspects of research on programmable data-planes, like algorithms/data structures, security, scalability, compilation, and evaluation.
- Dataplane programmability beyond L3/L3: the emerging service mesh data plane implements complex packet processing functions that go beyond the capabilities of current programmable data plane models and implementations, which are limited to Layer-3/Layer-4 protocol processing (IP/TCP/UDP). This topic aims at extending programmable data plane models to these new container networking to these Layer-7 centric (HTTP, gRPC, WebSocket, etc.) use cases.
- General theory of packet routing: comparison and development of distributed and centralized approaches, the study of routing in emerging network architectures and routing paradigms, scalability studies, complex networks, etc.
