A Framework for eBPF-Based Network Functions in an Era of Microservices

By moving network functionality from dedicated hardware to software running on end-hosts, Network Functions Virtualization (NFV) pledges the benefits of cloud computing to packet processing. While most of the NFV frameworks today rely on kernel-bypass approaches, no attention has been given to kernel packet processing, which has always proved hard to evolve and to program. In this article, we present Polycube, a software framework whose main goal is to bring the power of NFV to in-kernel packet processing applications, enabling a level of flexibility and customization that was unthinkable before. Polycube enables the creation of arbitrary and complex network function chains, where each function can include an efficient in-kernel data plane and a flexible user-space control plane with strong characteristics of isolation, persistence, and composability. Polycube network functions, called Cubes, can be dynamically generated and injected into the kernel networking stack, without requiring custom kernels or specific kernel modules, simplifying the debugging and introspection, which are two fundamental properties in recent cloud environments. We validate the framework by showing significant improvements over existing applications, and we prove the generality of the Polycube programming model through the implementation of complex use cases such as a network provider for Kubernetes

Environment for the People

Environment for the People, a joint publication of PERI and the Centre for Science and the Environment (CSE) in India, documents innovative strategies used by environmental activists around the world to build natural assets. In diverse landscapes, from Bangladesh's riverine delta to Somalia's arid uplands, ommunities are investing in ecological restoration. In 'extractive reserves' in the Amazon rainforest, the defense of sustainable livelihoods goes hand-in-hand with defense of bio-diversity. In the Peruvian Andes, indigenous communities are fighting to protect their lands and water from the ravages of the mining industry. And in cities around the world, from Los Angeles to New Delhi, communities are mobilizing to defend the right to clean air. These and other inspiring cases profiled in Environment for the People illustrate that humankind does not face an inexorable 'tradeoff' between protecting the natural environment and improving economic well-being. On the contrary, struggles for environmental protection and sustainable livelihoods are bound together
