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.

These white papers summarize a series of PoC, Packet and Optical, conducted by the CANDI work group and the lessons learned after the trials. CANDI will continue to contribute to conducting enhanced PoCs to test and confirm of agreed upon use-cases and find the issues for developing the technology required to confirm the feasibility of operator’s use-cases.

In this paper, we explain and outline the accomplishments and goals of the Open Optical & Packet Transport (OOPT) project group within Telecom Infra Project. This group defines open technologies, architectures and interfaces in Optical and IP Networking.

In this whitepaper, we explore the opportunities, use cases, and challenges of IP/Optical convergence through IP-over-WDM capable routers and we highlight the main objectives of the MANTRA Operator’s signing this whitepaper.

A worldwide top-ranked Network Operators group, formed by Telefonica, Vodafone, MTN, Telia Company,Deutsche Telekom and Orange, have joined efforts to collaborate on Open Transport SDN within the Telecom Infra Project Open Optical and Packet Transport (OOPT) project group. These operators will be leading a new workstream called MUST (MUST: Mandatory Use case requirements for SDN for Transport). This White Paper presents the common architectural view, the use case-based methodology and the selection of the most relevant standard interfaces to be implemented by the industry.

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.

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.
