ON.Lab Lets New SDN OS Fly

By Paula Bernier June 04, 2015

ON.Lab this week uncaged the latest iteration of the software defined networking Open Network Operating System with the introduction of Cardinal. This release, which is version 1.2, includes enhancements related to interoperability, MPLS, and performance on a number of fronts.

The non-profit organization, whose members include AT&T, Cisco, Ericsson, Fujitsu, Huawei, Intel, NEC, and NTT Communications, lets a new release of ONOS fly every three months. The previous releases were Avocet and Blackbird.

Cardinal delivers performance improvements of more than 25 percent for application intent processing, flow operations, and network topology maintenance. Its Application Intent Framework, which enables apps to specify their network control requests based on policy, now has extensions for MPLS and tunneling. And Cardinal creates several new use cases for ONOS by allowing the central office to be re-architected as a data center; ON.Lab refers to this concept as CORD.

Other improvements with Cardinal include the introduction of a flow-objective subsystem in the distributed core. This allows for device-agnostic SDN deployments, enabling apps to use various OpenFlow switches with multiple tables. ON.Lab says this is a big step toward interoperability and the elimination of solution silos that have become so common in legacy networks.

NETCONF and PCEP southbound interfaces are also supported by Cardinal, and ON.Lab is working on TL1, which it expects to deliver for open source distribution in the future.

“The ONOS team has been running on all cylinders and continues to increase momentum with the help from the community,” said Bill Snow, vice president of Engineering at ON.Lab. ”The code base continues to add functionality, while keeping code quality high and continually improving performance. ONOS’ use cases really show its unique capabilities to transform service provider and mission critical networks.”
