Title: Towards superfluid Network Function Virtualization (NFV)
Abstract: Network Softwarization is an overall trend that is changing the way in which communication networks are designed, implemented, deployed and run. The Network Function Virtualization (NFV) paradigm is an important part of this trend: functions that were traditionally run in physical network nodes are now virtualized and executed over commodity hardware in data centers, similar to what happens with Cloud Computing for IT servers.
Starting from the NFV paradigm, the EU research project Superfluidity promotes the vision of “superfluid” network, which will have the ability to instantiate services on-the-fly, run them anywhere in the network (core, aggregation, edge), exploit heterogeneous hardware and virtualized resources. The Superfluidity solution is based on: a decomposition of network components and services into elementary and reusable primitives; a native, converged cloud-based architecture; the virtualization of radio and network processing tasks; platform-independent abstractions, which permit the reuse of network functions across heterogeneous hardware platforms.
In the talk, after presenting the Superfluidity vision, I will focus on a couple of specific topics:
– The Unikernels lightweight virtualization technology and its management aspects;
– Modeling and composing Virtual Network Functions: the quest for the Orchestrator.
