Motivation driving IPDR use cases

DOCSIS downstream

DOCSIS upstream

Hot IPDR use cases in Cable

»  Today   Service aware capacity management

  DOCSIS aware subscriber usage monitoring

  Policy-based congestion mitigation (aka. ‘fair use’)

  DOCSIS network intelligence & subscriber analytics

»  Tomorrow   Node aware capacity management   Metered billing   Service assurance & proactive network maintenance

Engineering Change Status

OSSIv3.0-N-10.0968-2 Spectrum measurement, CM US, US/DS utilization and logging service changes

OSSIv3.0-N-10.0970-2 Update minimum intervals for IPDR Time Interval Session types

OSSIv3.0-N-10.0972-2 Correct references to SAMIS Session behavior OSSIv3.0-R-10.0971-1 SAMIS update for Multicast traffic accounting

DOCSIS 3.0 IPDR Engineering Changes

Other MSO IPDR enhancement requests

»  Security   Current ACL approach in connect message

  Address securing connection between CMTS exporter and collector

  Leverage standard TLS toolkit

»  Class based rate limiting   Large numbers of embedded CM devices

  Some Service Flows more interesting than others (eg. CM vs. ASTB)

  Desire method to configure time based record export intervals on a

per Service Class (Name) basis
