Summary

The CATS working group meeting focused on updates and next steps for the three working group documents: Use Cases and Requirements, Framework, and Metrics. Key discussion points included issues with encryption, synchronization of data, and prioritization of requirements. There were discussions about collaboration with other standards organizations and whether to publish the use cases and requirements as an RFC.

Key Discussion Points

• CATS Framework: Discussion on handling encrypted service identifiers and how classifiers can function with encrypted traffic. Need to clarify which layer identifiers will be provided at. Concerns raised about manageability and the need for a document shepherd.
• CATS Use Cases and Requirements: Review of updates, including addressing comments and correlating use cases and requirements. Discussion of a new ISAC (Integrated Sensing and Communications) use case and associated requirements. Concerns raised about data synchronization. Prioritization of requirements and whether the use cases and requirements should be published as an RFC.
• CATS Metrics: Review of updates to the metric definition document. Discussions around the classification of metrics in several levels, clarification for vendors, and implementation guidance on using CATS metrics.

Decisions and Action Items

• CATS Framework:
  • Matt to send an email to the mailing list regarding the encrypted service identifier issue.
  • Working group to look at the PCE manageability considerations document.
