ICYMI: Group issues open source NFV app to spur expansion

In this week's SDN news, the OPNFV Project releases its open source NFV platform to help companies add virtual functions while NEC releases two new switches to help build large software-defined data centers.

In SDN news, the Open Platform for NFV (OPNFV) Project introduced Arno, open source software aimed at helping developers explore NFV's potential. NEC Corp. launched two SDN-compatible switches tailored to highly scalable large data centers. ONOS introduced Cardinal, the third release of its open source SDN operating system.

OPNFV introduces its first open source NFV development release

Following eight months of development, the Open Platform for NFV (OPNFV) Project released software aimed at helping companies build network functions virtualization (NFV) products and services. The software, OPNFV Arno, provides code that can support the use of NFV infrastructure (NFVI) and Virtual Infrastructure Manager (VIM) components of ETSI's NFV architecture. NFVI is a set of resources used to host and connect virtual network functions (VNFs). VIMs corral the necessary compute, switching and other resources from an SDN network's underlying infrastructure to enable the VNFs to work as designed.

"With Arno, we now have a solid foundation for testing some of the key resource orchestration and network control components for NFV," said Prodip Sen, chairman of the OPNFV board of directors, in a statement.

According to OPNFV, Arno enables continuous integration, automated deployment and testing of components from upstream projects including OpenDaylight, OpenStack and Open vSwitch. Users and developers can also deploy their own or third-party VNFs on Arno to test functionality and performance in various scenarios and use cases.

NEC releases SDN-compatible switches for large data centers

NEC Corp. has launched two switches engineered for software-defined data centers (SDDC). The SDN-compatible switches enable network configurations equivalent to several thousand server racks and are aimed at massive data centers operated by telecom carriers and service providers.

NEC said the switches, PF5340-48XP-6Q and PF5340-32QP, can support the design of a highly scalable data center.

PF5340-48XP-6Q is a top of rack (ToR) switch with a 48 10 GbE port interface to consolidate servers. The PF5340-32QP is an aggregation switch that consolidates multiple racks and is equipped with 32 40GbE ports.

"These new switches help resolve issues faced when increasing the size of data centers, among them the complexity of operation and difficulties in expansion," said Toshio Suzuki, general manager, Converged Network Division, NEC.

ONOS Cardinal to allow new deployments and POCs

ONOS has just issued the third release of its open source SDN Open Network Operating System, Cardinal, aimed at enabling new SDN deployments and proof of concepts (POCs). Among Cardinal's new features is a beefed-up southbound interface and enhancements to the application intent framework, the mechanism that enables applications to start a particular network component to perform specific tasks.

According to ONOS, the operating system will help service providers transform their legacy central offices into more modern data centers, a process popularly known as central office to be re-architected as a data center (CORD).

ONOS said Cardinal improves performance for flow operations, application intent processing and network topology maintenance by more than 25%.

The new flow-objective subsystem in the distributed core allows apps to use a variety of OpenFlow switches. ONOS says this is a big step toward making SDN more flexible and ending vendor lock-in.

Cardinal also adds several new protocols to the southbound interface, including NETCONF and PCEP.
