Building open and disaggregated transport networks
Disaggregated Open Routers (DOR)
Led by:
Eva Rossi (Vodafone)
Kenji Kumaki (KDDI)
Diego Marí Moretón (Meta)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.

Physical Simulation Environment (PSE)
Led by:
Gert Grammel (Juniper)
Andrea D’Amico (NEC Laboratories America)
Sai Kishore Bhyri (Infinera)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.

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.

Technical Requirements Documents
These documents contain the set of Detailed Technical Requirements and recommendations defined within the Mandatory Use cases for SDN Transport (MUST) subgroup for:
MUST Optical SDN Controller NBI Technical Requirements Document
This document aims to define the base requirements for any SDN Domain controller entity (e.g., a SDN-C) which is intended to expose the management/control capabilities of any use case such as activation/configuration, service provisioning, path-computation, fault management and monitoring over a WDM/OTN network, through the interface defined in this document.
TIP MUST Use Cases Definition Document | Optical planning
The purpose of describing the optical planning use cases is to provide a base for reviewing how the function of online optical planning should be incorporated into the TIP MUST Open Transport SDN Architecture. The scope of the optical planning is to plan the properties of Open-Optical Networks O-ON with its O-OLS (Open-Optical Line System) and connected O-OLI (Open Optical Line Interfaces). To prepare a proposal for implementation of the use case functionality, all necessary topics of relevance should be reviewed. In section 4, input is given for consideration on a solution, however this is not a complete description but the first set of important topics shared by the operators. Any other topics of relevance have to be identified during the continuing work.
TIP MANTRA Use Cases Definition Document
IPoDWDM-capable routers’ coherent pluggable integration and management.
This Use Cases Definition document extends the current MANTRA Whitepaper: IPoWDM convergent SDN architecture – Motivation, technical definition & challenges with an extended description of the target applicability scenarios and use cases targeted by the TIP OOPT MANTRA operators subgroup.
Router – Provider Edge (DDBR – PE)
This document represents the technical requirements for a distributed and disaggregated PE router (DDBR-PE) that operators can deploy in current and future networks for the provision of backbone services. It describes the required hardware and proposes non-mutually exclusive software packages for the support of additional services or functionalities.
Currently wireless networks are operated through vendor Network Management Systems (NMS) using proprietary interfaces. Operations and configuration/maintenance activities are performed manually and statically.
This adds complexity toward the higher-level applications and OSS systems that need to manage many proprietary interfaces. In the case of Microwave (MW) networks, these scale upward to non-reasonable levels due to technical complexity.
The purpose of this document is to describe a set of guidelines and recommendations for a standard use of the SDN Northbound interface of the Optical SDN domain controller for the implementation of the interface between network systems in charge of the control/management of networks based on WDM/OTN technologies.
This document aims to define the base requirements for any SDN Domain controller entity (e.g., a SDN-C) which is intended to expose the management/control capabilities of any use case such as activation/configuration, service provisioning, path-computation, fault management and monitoring over a WDM/OTN network, through the interface defined in this document.
The purpose of this document is to identify, describe and compile the set of use cases as well as define the requirements, flows and details of each use cases in Network Element (router) and IP Domain controller. MUST Deliverables are incremental in terms of specified use cases.
The purpose of these documents is to describe a set of technical requirements and recommendations for:
- This document provides the technical requirements of the North Bound Interfaces (NBI) mandatory to be exposed by IP Domain Controllers, which includes an IP Domain Path Computation Element.
- The purpose of this document is to describe the Optical SDN Controller SBI Technical Requirements for Open Terminals defined within the Open Optical Packet Transport (OOPT) working group.
Distributed Disaggregated Backbone Router (DDBR) Technical Requirements & DDBR Detailed Requirement Documents
The purpose of these documents is to describe a set of technical requirements and recommendations for:
- A proposal for the shift in the IP backbone architecture from monolithic chassis- based to a disaggregated Spine & Leaf architecture
- Describes the technical aspects of a Disaggregated Open Router (DOR) which is a versatile device that can be deployed in IP core/backbone networks

TIP Greenlight addresses these issues by the application of common and standards-based technologies:
- This first release of TIP Greenlight focuses on the initial deployment of network elements with disaggregated hardware (e.g. a router or a transponder) and software components (“disaggregated devices”)
- Future iterations of TIP Greenlight will build upon the flexible and extensible mechanisms contained in this document to deliver additional use cases.
The purpose of these documents is to describe a set of technical requirements and recommendations for:
- The SDN interface to be exposed by IP/MPLS Network Elements (routers) which will be consumed by the South Bound interface of IP SDN Controller.
- The SDN Northbound interface of the Optical SDN Controller in charge of the control/management of WDM/OTN networks
TIP MANTRA Whitepaper – IPoDWDM PoC 2024 results readout
This Use Cases Definition document extends the current MANTRA Whitepaper: IPoWDM convergent SDN architecture – Motivation, technical definition & challenges [1] with an extended description of the target applicability scenarios and use cases targeted by the TIP OOPT MANTRA operators subgroup.
Performance data streaming in the network plays a vital part for many applications like monitoring, network management, closed loop automation, and much more. This is getting complex when it comes to optical transport network, where streaming of performance data from multiple domains is required to manage the end to end optical service.
Therefore, a systematic approach is required for telemetry data streaming from optical domain controllers to facilitate its utilization to northbound applications. The ONF TAPI v2.5 is proposed with a telemetry streaming improvements and recommended respective YANG models and protocols to effectively support streaming of performance data from multiple domains.
