The goal of the

Open Optical & Packet Transport

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

background

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.

Join the Open Optical & Packet Transport Project Group to help accelerate innovation in optical and IP networks.

Building open and disaggregated transport networks

Disaggregated Cell Site Gateways (DCSG)

Led by:

Eva Rossi (Vodafone)

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)

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)

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.

Mandatory Use Case Requirements for SDN for Transport (MUST)

Led by:


Eva Rossi (Vodafone)

Esther Le Rouzic (Orange)

Juan Pedro Fernández Palacios Giménez (Telefónica)

Johan Hjortas (Telia Company)

Lloyd Mphahlele (MTN)

Andreas Gladisch (Deutsche Telekom)

 
The main objective of MUST (Mandatory Use Case Requirements for SDN for Transport) is to accelerate and drive the adoption of SDN standards for IP/MPLS, Optical and Microwave transport technologies.

Disaggregated Optical Systems (DOS)

Led by:

José Antonio Gómez (Vodafone)

Hideki Nishizawa (NTT)

Johan Hjortas (Telia Company)

 

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

  • Cassini: A new open packet/optical transponder contributed by Edge-core.
  • Phoenix: An open white-box L0/L1 transponder that operators can deploy on top/together with their existing line systems to increase the capacity of their optical networks.
  • Galileo: An Optical Packet Hardware platform design.

Network Operating Systems (OOPT-NOS)

Led by:

Wataru Ishida (NTT Electronics America)

Kingston Selvaraj (PaIC Networks)

 
This group focuses on a reference open source Network Operating System (NOS) that supports OOPT disaggregated hardware platforms offering the following benefits to accelerate the innovation in IP and Optical networks:

  1. Enable Hardware technology providers to validate the hardware functionality and performance,
  2. Allow NOS technology providers to benchmark against, or give NOS technology providers or SI a leg up to build on,
  3. Allow Optical solution technology providers (SI) to validate optical solutions without partnership with commercial NOS providers,
  4. Offer Connectivity operators with in-house service and software development and operations skillsets to be more agile to meet new business requirements. (shorter time to business).

Disaggregated Open Routers (DOR)

Led by:

Kenji Kumaki (KDDI)

Eva Rossi (Vodafone)

 
This group focuses on defining a build open and disaggregated aggregation and core routers that operators can deploy in their current IP/MPLS networks making the network ready for 5G deployments. The team produces technical specifications that define software, hardware and API requirements and build solutions meeting that specification through industry partners and Technology providers

Highlighted technologies

OpenBNG

The TIP OpenBNG Technical Requirements document is the result of the collaboration between Telefónica, Deutsche Telekom, BT, Vodafone, with large scale fibre-to-the-home (FTTH) networks, within the Telecom Infra Project (TIP).

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:

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.

Deliverables

This paper provides the TIP OOPT MUST target architecture for Disaggregated Open Optical Networks. We describe the meaning of “Open”, the functions associated with the use cases and the degree of “Disaggregation” of the monolithic transport optical system.
The main sections of this white paper will discuss Open-Optical Terminals (O-OT), focusing on Open-Optical Line Interfaces (O-OLI), Open-Optical Line Systems (O-OLS), Open-Planning and Impairment Validation (O-PaIV) and the management guidelines via SDN and APIs.
