Building Open and Disaggregated Transport Networks
The Open Optical & Packet Transport (OOPT) Project Group 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.
Featured Technologies
DDBR (Disaggregated Distributed Backbone Router)
Disaggregated Distributed Backbone Router (DDBR) is a versatile device that can be deployed in IP core/backbone networks as an IP/MPLS core/edge routers (P/PE routers) or an Internet Gateway router (IGW).
Its unique Disaggregated and Distributed Architecture helps to disjoint the innovation paths and moving away from costly platforms with efficient scalability and deterministic latency.
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.

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.

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. It is based on disaggregated components (HW and SW) with 400G line interfaces.

Galileo
An Optical Packet Hardware platform design. It’s a 1RU form factor with 12 QSFP28 ports and 4 Plug-In Unit line card slots.
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.
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 Company, Cisco, Juniper, Politecnico di Torino and Facebook.
TAI
Transponder Abstraction Interface – An API that provides a vendor-independent mechanism to control optical components. It simplifies the integration work between a network operating system and the underlying optical hardware.

Mandatory use Case Requirement For SDN For Transport (MUST)
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.

Physical Simulation Environment (PSE)
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, Meta, Juniper, Microsoft, Orange, Politecnico di Torino and Telia Company — have made great contributions to build this tool.

Disaggregated Open Router (DOR)
This group works on the definition of open and disaggregated routers including Core (P), Provider Edge (PE), Aggregation Routers, Internet Gateways and Cell Site Gateway Devices that operators can deploy in their IP/MPLS networks and 2G/3G/4G and 5G cell sites. The team produces technical specifications that define software, hardware and API requirements that represent the needs of mobile / fixed network operators and build solutions meeting that specification through industry partners and Technology providers.

Metaverse-Ready Architecture For Open Transport (MANTRA)
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.
