Coriant Enterprise End-User SDN Service Trial and New SDN Solutions Portfolio


October 24, 2014

Virtualization is a major, if not the major component of transforming network infrastructure and it is happening both in enterprise data centers, service provider data centers and involves the interoperability of both. Much of this activity involving both Software Defined Networking (SDN) and the closely related Network Functions Virtualization (NFV) now underway with service providers is reflected in the recent announcement from SDN solutions provider Coriant.

The company is out with its Coriant Transcend™ SDN Solution. It is characterized as providing an advanced programming environment and open interfaces that, “Empower on-demand, application-centric service agility and direct monetization of network assets (NaaS), while retaining optimal end-user performance in an increasingly unpredictable traffic environment.” At the same time it introduced its SDN solution, it also announced its deployment in a live service trial of enterprise end-users with a Tier 1 service provider in Asia.

A comprehensive approach to SDN

Coriant, which has established itself in the metro-to-core transport solutions space serves over 500 customers globally, including 90 percent of the world's top 50 service providers. It has leveraged its transport expertise in the development of the Coriant Transcend™ SDN Solution which is comprised of two major components:

  • An SDN software suite that includes the Coriant Transcend™ Orchestrator based on the OpenDaylight Project, the Coriant Transcend™ Transport Controller, the Coriant Transcend™ Application Suite, and integration of Open Virtual Switch (OVS) functionality for Network Function Virtualization (NFV).
  • The SDN enablement of the Coriant Dynamic Optical Cloud™ product and services portfolio, including industry-leading metro-to-core packet optical transport (mTera™ UTP, 7100, hiT 7300, 7090) and smart router (8600, 8800) offerings.

The solution couples the benefits of SDN and NFV. It is aimed at the delivery of new services and functionality not just for not only enterprises but the mass market as well.  These include such capabilities as: application-based forwarding, network virtualization and defragmentation, and zero-touch service provisioning.

"An SDN-based solution transforms today's rigid transport infrastructure into a highly programmable network, one that is just as flexible, efficient and seamlessly scalable as data center computing and storage resources," stated Stu Benington, VP of the Cloud and SDN Business Unit for Coriant. "The Coriant Transcend™ SDN Solution enables true SDN capabilities, versus other solutions that fail to fully address the requirements related to multi-layer, multi-domain and multi-vendor integration."

The company also points out that the solution is SDN ecosystem friendly providing data center connectivity, mobile backhaul and IP/optical transport infrastructure, and is designed to speed the development of new applications and services by vendors, third-party developers, and the service providers themselves.

While we are still in what has been called the “nascent” stages of SDN and NFV transformations, with lots of issues to be ironed out and promises kept, there is no denying that SDN and NFV are the future of network infrastructure. Making networks simpler to manage, cost-effective, scalable, adaptive to the accelerating pace of innovation, and secure using software to automate “E”verything is the consensus path forward. As noted at the top, network virtualization is the key to accelerating business transformations for enterprises and service providers alike and we are starting to see some innovative approaches that tie all of the necessary pieces of the SDN and NFV puzzle together so that compelling customer experiences can be offered with high quality and performance assured.

Day 4 was the final day of our first ever Cisco Live! We had a great show, with many great conversations and new connections with existing and potential end users, resellers, partners and job hunters.

Day 3, Cisco Live! 2017

Day 3 of Cisco Live is history! For Fiber Mountain, we continued to enjoy visits from decision makers and influencers who were eager to share their data center and structured cabling challenges.

Day 2, Cisco Live! 2017

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.
