Open Optical & Packet Transport

Our goal is to accelerate innovation in optical and IP networks and ultimately help operators provide better connectivity for communities all around the world.

Open Optical & Packet Transport

The Open Optical & Packet Transport group is a project group within Telecom Infra Project that works on the definition of open technologies, architectures and interfaces in Optical and IP Networking.

The project is an engineering-focused effort led by major operators, technology vendors and research institutions. It concentrates on different parts of the Transport network architecture, including optical transponders, line systems, IP access devices, open APIs and network simulation and planning tools.

Open Optical & Packet Transport

Group Structure

The Open Optical & Packet Transport project group is currently divided into five different subgroups, focusing on different parts of the stack.

Co-Chaired by Hans-Juergen Schmidtke (Facebook)
Co-Chaired by Victor Lopez (Telefónica)

Disaggregated Cell Site Gateways (DCSG)

Led by Eva Rossi (Vodafone) and Luis MartinGarcia (Facebook)

This group works on the definition of open and disaggregated whitebox cell site gateway devices that operators can deploy in their current 2G/3G/4G cell sites, as well as in the upcoming 5G deployments. The team produces technical specifications that define software, hardware and API requirements that represent the needs of mobile network operators and also works with industry partners to develop devices that meet the specifications.

Physical Simulation Environment (PSE)

Led by Gert Grammel (Juniper) and Gabriele Galimberti (Cisco)

This group represents the first industry-wide effort to develop an open-source multi-vendor tool for optical network planning. The tool is in active development and with it, operators will no longer have to depend on their suppliers to plan routes and network capacity, but will have an independent way to lay out their requirements and simulate network conditions. Project group members — including Cisco, Facebook, Juniper, Microsoft, Orange, Politecnico di Torino and Telia Company — have made great contributions to build this tool.

Converged Architectures for Network Disaggregation & Integration (CANDI)

Led by Hirotaka Yoshioka (NTT) and Oscar González de Dios (Telefónica)

This group focused in defining operator use cases in open converged packet and optical networks. Also, prove that use cases can be met with architectures based on open technologies and finally leverage the opportunity provided by TIP to involve different players to accelerate technical developments and help operators in real-world scenarios.

Controls, Information Models & APIs (CIMA)

Led by Alan Gibbemeyer (Acacia), Harald Bock (Infinera), and Stephan Neidlinger (Adva)

The focus of this group is to drive practical, multi-vendor implementations supporting operator-driven open optical use cases Define a recommended set of control architectures, information models and APIs to enable focused implementation efforts and progress toward real-world deployment.

Disaggregated Optical Systems (DOS)

Led by José Antonio Gómez (Vodafone), Hideki Nishizawa (NTT), and Johan Hjortas (Telia Company)

This group focuses on defining a build open and disaggregated Optical devices and taking them to market.

Highlighted Technologies

DCSG

DCSG is a 1RU fully-featured cell site router with a wide range of Ethernet connectivity options for client and network sides. As a cell site gateway, DCSG supports Layer-2, Layer-3 and MPLS features – with native time synchronization protocols such as
IEEE-1588 v2 and Synchronous Ethernet for the mobile base stations.

For more information, download our DCSG at a glance PDF.

Voyager

Industry’s first open and disaggregated converged packet/optical transponder. Voyager was an original design contributed by Facebook that is now being evolved and taken to market by Adva Optical, running software from Cumulus Networks.

Cassini

A new open packet/optical transponder contributed by Edge-core. Cassini integrates 100GbE switching with Layer-1 optical transport functions as line-card modules, and covers data center interconnect, metro and access backhaul use cases.

For more information, download our Cassini at a glance PDF.

GNPy

An open-source library for building route planning and optimization tools for real-world multi-vendor optical networks. GNPy is a community effort participated in by partners such as Orange, Microsoft, Telia Carrier, Cisco, Juniper, Politecnico di Torino and Facebook.

Key Software, Device and Component Vendors in the Telecom Infra Project Create Industry-First Standard Software Interface for Optical Modules and Systems

October 16, 2018

Device, component and software vendors work together to create an industry-first interface for optical modules to allow fast integration of elements in disaggregated optical systems.

Disaggregation is a trend on the rise that speeds up innovations by breaking a technology into smaller discrete pieces that different companies can independently work on in parallel. This brings flexibility to choose the best technology for each piece at any point in time, but also requires integrating all the components into a final product.
