JOCN Special Issue on Advanced Monitoring and Telemetry in Optical Networks


Submissions Open: 1 February 2021
Submission Deadline: 24 February 2021

Service providers have made it clear that they are looking beyond physical capabilities when selecting their networking ecosystems. The network's ability to collect, aggregate and analyze performance metrics, and take action in response to this data analysis is of growing importance, with an increased emphasis on streaming telemetry rather than legacy polling techniques. In contrast to network attributes such as transmission capacity where growth has been slowed by physical realities, advancements in monitoring and processing capabilities have accelerated the potential use of telemetry to drive network operation. The challenge is to hone the effort and harness the tracked data to maximize the advantages that can be obtained. To more fully investigate these challenges, this special issue is focused on the intelligent use of monitoring and telemetry to control and manage optical networks.

While increased monitoring potentially exposes an array of performance metrics, data explosion is a prime concern. Solutions must remain scalable; it is essential to determine which telemetric data can be most effective in network management, whether it be automating common tasks or driving new and advanced applications. Other fundamental considerations are the monitoring frequency and where the data should be collected and/or analyzed (e.g., distributed at the network elements or more centralized), and the ensuing ramifications for communication/processing burden and optimality.

The ultimate goal, of course, is taking full advantage of the collected telemetric data. One can envision a wide range of applications. For example, it is natural for monitoring to become an integral part of a software-defined network to drive automation. Performance data can be tracked for purposes of failure prediction, to enable pro-active mitigation prior to connection failure. Similarly, monitoring can be used to provide advance warning of potential network-element misconfiguration. Telemetry from multiple networking layers or domains can be synthesized to achieve efficient multi-layer/multi-domain control. Data anomalies can be used to detect a security breach. It is also worthwhile to consider advanced monitoring that may be needed in the future to more fully reap the operational benefits.

The scope of the special issue includes but is not limited to the following topics:

  • Evaluation of which optical-network telemetric measures are the most beneficial to track and their optimal tracking frequency
  • Application and configuration of monitoring tools, including optoelectronic devices
  • Applications of telemetry for quality of transmission estimation, quality of experience evaluation, dynamic resource optimization, anomaly detection, failure prediction, misconfiguration prevention, and security
  • Centralized vs. distributed vs. hierarchical monitoring and processing of telemetry in an optical network
  • Optical-layer specific techniques for scalable data capture, storage, visualization, correlation and integration
  • Pros/cons of proactive response to telemetric anomalies: e.g., avoiding failed connections vs. false positives
  • Machine-learning based applications of telemetry in optical networks
  • Protocols/interfaces best suited for telemetry and real-time monitoring given bandwidth & latency constraints
  • Monitoring and telemetry in open/disaggregated optical systems, e.g., interoperability issues, determining the faulty entity when a problem arises.
  • Monitoring and telemetry in multi-layer / multi-domain / multi-band / multi-technology networks
  • Security issues and practical use of blockchain to track the veracity of collected telemetry

Submissions to the special issue should be prepared according to the usual standards for the Journal of Optical Communications and Networking and will undergo the normal peer review process. Manuscripts must be uploaded through OSA's online submission system specifying from the Feature Issue drop-down menu that the manuscript is for the issue on Advanced Monitoring and Telemetry in Optical Networks.
