Creating standards for higher-speed networks of tomorrow

The networks of tomorrow will need higher speeds than networks of the past. 

That’s because new applications are increasing bandwidth needs in fiber optic networks.  In addition, cloud computing leads to greater variability in traffic destinations. Customers need new technologies to support communications and dynamic network reconfiguration at higher speeds.

For DWDM (dense wave division multiplexing) transport technologies, the Optical Internetworking Forum (OIF) is the leading industry standards body.  Recently the OIF completed work in 2 critical areas for cost-effective higher-speed networks: Multi-Layer Network and Next-Generation Optical Interconnects.

Defining Multi-Layer Network Standards

The Multi-Layer Network Control Implementation Agreement defines how low-speed services (such as Ethernet Private Lines) can invoke connections on high-speed networks, which enables greater new service velocity and lower cost for delivery.  Tellabs has been a key contributor to this Implementation Agreement, bringing in key concepts for Multi-Layer operations such as our patented methods for Multi-Layer routing.

Defining Standards for Next-Generation Optical Interconnects

The Next-Generation Optical Interconnects Framework focuses on the interconnects needed as interface speeds transition to 400G and beyond.  When networks operate at speeds more than 150 times greater than the typical interfaces of 10 years ago, increased interface speeds create new challenges for intra-shelf and intra-system connectivity.

The OIF Framework defines use cases that will guide future solutions. Tellabs was an early contributor to this Framework document, providing early requirements for multi-chassis system applications.

Initiating a Framework for Transport SDN

The OIF is extending its leadership in high-speed networks by initiating a new project to define a framework for Transport SDN (software-defined networking).  Proposed by Tellabs, the goal of this document is to define the internal and external interfaces required by a Transport SDN controller.

As with other OIF frameworks, the creation of actual specs for such interfaces will be a separate activity. OIF leverages the work of other standards bodies (such as the ONF's OpenFlow) whenever it’s possible.

Tellabs is committed to helping our customers advance with smart high-speed networks.  We’ve been a long-standing participant in the standardization of interfaces related to Fiber Optic communications. These standards include the FSAN and ITU-T standards for access, as well as IETF, IEEE, ITU-T and OIF for core technologies such as packet and DWDM.

Advancing the standards today is key to advancing networks tomorrow. The OIF facilitates standards discussions to enable interoperability and development of a broader ecosystem. For more detail on the latest OIF standards, click here.
