Overview

The P4 programming language offers the potential to facilitate more rapid testing and deployment of new network functions and services through an open source software interface to the underlying hardware of capable network equipment. There is a growing international P4 community, and a number of organisations interested in the technology within the European R&E community. P4 is primarily supported by vendors of “white box” equipment.

The GÉANT GN4-3 project started on 1 January 2019; it includes activities within WP6 Task 1 on white box technology and data plane programmability (DPP). The latter activity includes the initial use case of network monitoring (e.g., Netflow or counter-based monitoring, or in-band packet telemetry, generation of enhanced flow characteristics), but is expected to extend to other areas, potentially including DDoS mitigation. Platforms that are being used are expected to include FPGA equipment and also Tofino-based Wedge equipment. During the first months of the project the existing work done and anticipated use cases will be documented and proposed; this BoF aims to describe and solicit feedback and discussion on the proposals.

In the search for future Internet technologies (such as SCION, RINA and NDN) that can support secure, stable and transparent functions, the 2STiC Programme (a cooperation between NLnet Labs, SIDN Labs, SURFnet, TUDelft, UTwente and UvA) is looking at P4-enabled networks to be able to test these future Internet technologies in a multi-domain environment. Aspects like data plane, control plane including management functions will be of importance. The initial experience around a multi-domain P4 testbed using In-band Network Telemetry (INT) for hop recording will be shared with the community. Members of the 2STiC Programme will contribute to the BoF.

The BoF aims to help build a the P4 community within the R&E environment (including GÉANT, NRENs, campuses and research organisations), focusing on use cases for P4, building expertise through the sharing of best practices, including experiences and examples of P4 software being used, and exploring TNC2019 potential common use cases and opportunities.
