Description of the research topic:
In the past years a new paradigm called Software Defined Networking (SDN) has emerged that aims at simplifying many aspects of networking. The key idea behind SDN is the separation of data and control planes in switching devices and opening the control plane to be supervised by a logically centralized software controller, greatly simplifying the definition and deployment of innovative services and also the management of SDN devices. Current SDN solutions only focus on the programmability of the control plane, and consider the data plane as a collection of simple forwarding elements. However, this limitation of the data plane has many drawbacks, obstructing the development of optimal networking solutions and the rapid innovation in computer networks. In 2014, with the leadership of Jennifer Rexford (Princeton University) and Nick McKeown (Stanford University) a group of researchers proposed a new architecture and programming language called P4 [1,2] for protocol independent packet processing. P4 is often regarded as a key milestone toward OpenFlow 2.0.
This research topic focuses on the new packet processing model of P4 and aims at answering different research questions from the following fields:
* New network algorithms for traffic engineering solely in data plane e.g. traffic shaping
* L4 load balancing in telecom and data centre networks
* Utilization-aware routing
* Data plane-driven TCP performance acceleration
* In-network Paxos
* Anomalous and malicious traffic behaviour detection and mitigation in data plane
* Detection and diagnosis of performance problems by measurements in the data plane
