IEEE International Conference on Cloud Networking, 4-6 November 2019 in Coimbra (Portugal).

This paper researched the issue with the vendor-independent programmability of traffic and buffer management of virtual switches in the cloud infrastructure, and proposed a way of how to implement this programmability with software-defined networking technologies, in particular with P4.

As a case study, the work also proposed a packet scheduling algorithm, which prioritizes the traffic based on user-defined classification and utilizes the available network resources in a scalable way, which improves the performance of latency-sensitive applications (e.g. HPC, Edge) deployed in the cloud infrastructure.

Apart from the easier deployment, SODALITE targets the performance. With the algorithm developed and traffic management programmability established, the work introduces application performance optimization targeting networking performance at runtime, which can be introduced to the platform as part of the runtime (dynamic) optimization. The work will be evaluated in the context of SODALITE.
