Hierarchal SDN is a key enabler for hyperscale cloud data centers, says Brad Booth



Microsoft announced several new Azure networking services and features, including expanded ExpressRoute connectivity to other Microsoft Cloud services like Office 365 and Skype for Business Enterprise Voice. Some of the new features include: Standard VPN gateway enabling Site-to-Site (S2S) connectivity to a Virtual Network that also has a gateway connected to an ExpressRoute circuit.

We want a scalable, highly-available, high-performance network operating system, says Guru Parulkar




A new version of the Open Network Operating System (ONOS), named Blackbird, has been released (the first version of ONOS was out in December 2014). 

ONOS features a highly available, scalable SDN control plane featuring northbound and southbound open APIs and paradigms for a diversity of management, control, and service applications across mission critical networks. It is architected as a distributed but logically centralized control plane to achieve high performance, scale-out and high availability. ONOS' high availability characteristics include full recovery from events such as switch and link failure, node failure, entire ONOS cluster failure, single node cluster failure, cluster partitioning and device-node communication failure.

The ONOS Blackbird release defines the following set of metrics to effectively measure performance and other carrier-grade attributes of the SDN control plane.

The end goal of open networking is to have a scalable infrastructure that is also lower cost to manage, says John Healy



The end goal of open networking is to have a scalable infrastructure that is also lower cost to manage, says John Healy, General Manager of the SDN Division at Intel.

Open means more open in terms of standards and vendors. It also means being capable of working with the open source community.

Update on OPNFV with Prodip Sen




OPNFV is an open source project under The Linux Foundation aimed at accelerating the introduction of NFV products and services. Prodip Sen, CTO of Network Functions Virtualization at HP and Chair of the OPNFV Project, provides a quick update of the community and its first release -- "Arno".

Arno provides an initial build of the NFV Infrastructure (NFVI) and Virtual Infrastructure Manager (VIM) components of ETSI NFV architecture. The baseline release enables continuous integration, automated deployment and testing of components from upstream projects such as Ceph, KVM, OpenDaylight, OpenStack and Open vSwitch.
