Optical Internetworking Forum tests SDN transport API

Optical Internetworking Forum (OIF), in collaboration with MEF, successfully concluded its 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) multi-vendor interoperability demonstration.


The multi-vendor demo led by four network operator labs included lab deployed and cloud deployed systems testing new dynamic behavior use cases and deployment scenarios. The demo also incorporated service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines extensions to T-API in support of Carrier Ethernet services.

“The OIF SDN Interoperability demonstration has successfully brought together carriers, vendors and integrators with a common goal of moving to an open API (TAPI),” said Jack Pugaczewski, Distinguished Architect, CenturyLink. “T-API is a key enabler for providing automated service fulfillment and assurance. We have tested the Connectivity, Topology and Notification software patterns that T-API provides. Common APIs reduce design, development and deployment cycles for all involved, thus getting to market faster and realizing the financial benefits of automation.”

Participating network operators were CenturyLink, China Telecom, SK Telecom and Telefónica and vendors included ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) was a participating academic institution and TELUS Communications participated as a consulting network operator.

“The OIF’s goal for interop events is to improve the quality and clarity of specifications being tested,” explained Jonathan Sadler, OIF VP and Networking & Operations Interoperability Working Group Chair. “As the tests were performed, we noted possible points for misunderstanding and places where the specifications may be enhanced. These results will be liaised to ONF and MEF for review at future meetings.”

Acacia offers Coherent ZR Optics for CFP and CFP2 Pluggable Modules

Acacia Communications announced the general availability of two new high-speed coherent optical interconnect products for “ZR” applications in access, edge, and enterprise campus networks.

Acacia's new 100G/200G CFP2-DCO ZR and next generation low power 100G CFP-DCO ZR are enabled by the company's proprietary digital signal processor (DSP) and silicon photonic technologies.

Acacia said its new products support the requirements of unamplified applications beyond the 40km reaches standardized in the industry and extend to 80km and beyond.

Acacia’s CFP-DCO ZR module is capable of supporting the 18W power class that was widely deployed for 10km client applications. Both modules also offer high-capacity and low-power consumption solutions designed to reduce the complexity, power usage and cost of high-bandwidth interconnects.

“Traditionally, coherent optical transmission was primarily used for longer reach applications, but traffic patterns are changing in ways that are leading to the need for high capacity interconnects that target shorter reaches in a power efficient and cost effective manner. ZR optics address this need,” said Tom Williams, Senior Director of Marketing for Acacia Communications. “Acacia pioneered the coherent ZR offering with our industry first CFP-DCO form factor and our vision is to continue to expand the use of coherent technology in shorter reach applications.”

IEEE adopts OpenFog Reference Architecture

The IEEE Standards Association (IEEE-SA) has adopted The OpenFog Consortium’s OpenFog Reference Architecture for fog computing as an official standard.

The new standard, known as IEEE 1934™, relies on the reference architecture as a universal technical framework that enables the data-intensive requirements of the Internet of Things (IoT), 5G and artificial intelligence (AI) applications.

“We now have an industry-backed and -supported blueprint that will supercharge the development of new applications and business models made possible through fog computing,” said Helder Antunes, chairman of the OpenFog Consortium and senior director, Cisco. “This is a significant milestone for OpenFog and a monumental inflection point for those companies and industries that will benefit from the ensuing innovation and market growth made possible by the standard.”

The OpenFog Consortium, which was founded more than two years ago, describes fog computing as a system-level horizontal architecture that distributes resources and services of computing, storage, control and networking anywhere along the cloud-to-things continuum. It supports multiple industry verticals and application domains, enables services and applications to be distributed closer to the data-producing sources, and extends from the things, over the network edges, through the cloud and across multiple protocol layers.

“The reference architecture provided a solid, high-level foundation for the development of fog computing standards,” said John Zao, Chair, IEEE Standards Working Group on Fog Computing & Networking Architecture Framework, which was sponsored by the IEEE Communications Society's Edge, Fog, and Cloud Communications Standards Committee. “The OpenFog technical committee and the IEEE standards committee worked closely during this process and benefited from the collaboration and synergies that developed. We’re very pleased with the results of this standards effort.”

OpenFog Consortium Releases its Reference Architecture

The OpenFog Consortium, whose founding members include ARM, Cisco, Dell, Intel, Microsoft, and Princeton University, published its OpenFog Reference Architecture, a universal technical framework designed to enable the data-intensive requirements of the Internet of Things (IoT), 5G and artificial intelligence (AI) applications.

Fog computing is the system-level architecture that brings computing, storage, control, and networking functions closer to the data-producing sources along the cloud-to-thing continuum. The new reference architecture aims to enable high-performance, interoperability and security in complex digital transactions.

In brief, the OpenFog Reference Architecture contains a medium- to high-level view of system architectures for fog nodes (smart, connected devices) and networks, deployment and hierarchy models, and use cases. It is based on eight core technical principles, termed pillars, which represent the key attributes that a system needs to encompass to be defined as "OpenFog." These pillars include security, scalability, openness, autonomy, RAS (reliability, availability, and serviceability), agility, hierarchy and programmability.
