UNIFY Service Provider DevOps: opportunities for NRENs

The FP7 UNIFY project enables flexible and rapid service introduction in software-defined infrastructures combining compute, network and storage resources within the telecom carrier network domain that supports service chaining and network function virtualization. The roles of developers and operators in a software-defined telecom infrastructure change with respect to traditional TMForum or ITIL definitions. We discuss these changes in line with our draft submitted to the NFV Research Group at IRTF. A significant part of the configuration management tasks of Operators, as well as of Developers attempting to test their code in production-like environments, are expected to be automated by resource orchestration processes in the UNIFY architecture. The SP-DevOps Observability process in turn is expected to automate a significant part of the tasks related to monitoring and performance management. In this presentation, we will focus on functionality related to the Observability process as basic building blocks are more advanced in terms of development. Two tools developed to support the SP-DevOps Observability process with particular focus on software-defined networks will be presented. One tool allows evaluating packet loss and potentially delay on traffic described using aggregate flow descriptors in OpenFlow-compatible switches. The second tool produces accurate load estimates locally, close to where the raw data is produced was developed and evaluated. The approach is based on local high rate flow counter updates, including a flexible mechanism to install and modify monitoring functions that read the counters at variable rates. Finally, we examine opportunities for integrating our functionality with perfSONAR.
