Abstract

Network programmability based on the P4 language is gaining consensus in multiple scenarios, including edge computing. In this work, we present the P4-based edge networking solutions adopted in the framework of the EU-funded BRAINE Project. The project targets the design and development of a powerful edge micro data center (EMDC) aiming at boosting artificial intelligence (AI) at the network edge. The EMDC will encompass an embedded programmable P4 ASIC supporting unprecedented intra- and inter-edge/fog interconnection. In this paper, a selection of the solutions to be supported by the P4 switch embedded within the BRAINE EMDC is presented. They include decentralized traffic engineering solutions driven in-band telemetry (INT), quality of service enforcement and verification, 5G network function virtualization, and decentralized cyber-security at the edge.
