This paper presents Polycube, an open-source software framework based on eBPF, that enables the creation of arbitrary and complex network function chains. Each function can include an efficient in-kernel data plane and a flexible userspace control …
Iptables, which is currently the most common firewall on Linux, has shown several limitations over the years, with scalability as a big concern. This paper reports the first results of a project that aims at creating a (partial) clone of iptables, …
OpenFlow represents a new powerful paradigm that combines the flexibility of the software with the efficiency of a programmable hardware switch. However, such an approach is currently reserved for new hardware devices, specifically engineered for …
Virtual Network Functions (VNFs) are often implemented using virtual machines (VMs) because they provide an isolated environment compatible with classical cloud computing technologies. Unfortunately, VMs are demanding in terms of required resources …
