SONATA’s contribution to SDN & OpenFlow Congress is two-fold: it organises a workshop session and présents a paper on “Understand Your Chains: Towards Performance Profile-based Network Service Management”.
The workshop session at the SDN & OpenFlow World Congress is scheduled on October the 12th at 3:35 pm (2 hours)
Objective is two-fold:
In addition, the “Understand Your Chains: Towards Performance Profile-based Network Service Management” paper was accepted for EWSDN’16 which was co-located with the SDN & OpenFlow World Congress 2016. The paper is presented on October 10th. It analyses and discusses the components needed to generate such performance behavior information within the NFV DevOps workflow. It also outlines research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, it introduces a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure. Indeed, allocating resources to virtualized network functions and services to meet service level agreements is a challenging task for NFV management and orchestration systems. This becomes even more challenging when agile development method- ologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. One solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services.
Agile Service Development and Orchestration in 5G Virtualized Networks
SONATA is developing a NFV framework that provides a programming model and development toolchain for virtualized services, fully integrated with a DevOps-enabled service platform and orchestration system. SONATA initial results include:
