BPFabric: Data Plane Programmability for Software Defined Networks

Simon Jouet, Dimitrios P. Pezaros
2017 2017 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS)  
We introduce a control plane API that allows data plane functions to be deployed on-the-fly, reporting events of interest and exposing network internal state to the centralised controller.  ...  BPFabric leverages eBPF, a platform and protocol independent instruction set to define the packet processing and forwarding functionality of the data plane.  ...  This critical difference allows for a fully deterministic execution-time of a program, unlike a traditional instruction set, making it suitable for real-time processing in a bounded execution time environment  ...
