Presentation Transcript

  1. Proposal • Provide standard methodologies to cover a wide range of Network / Device Operational events • Complement - Augment existing ‘Device Reset Characterization’ document (RFC Ed Queue) • Many Operational events not covered by the recently approved RESET draft ’ are (but not limited to) HW and or SW Upgrades – Device failures / Crashes • Initial e-mail exchange http://www.ietf.org/mail-archive/web/bmwg/current/msg02257.html by Ilya Varlashkin

  2. Current Status • Current methodologies to characterize a reset / outage that may be applicable for additional events (time derive loss – start stop timer) • BMWG members indentified the need to go above and beyond current reset specific scenarios • Take these discussions and work to the OPSAWG (first need to scope the work)

  3. Scope of Work • Existing discussions within WG • Complexity of characterization of a ‘crash’ in a ‘black box’ testing exercise (induce the failure) • Device upgrade (RP / LC / firmware / hardware) real value in a production environment ? ( re-route traffic) (max-metric) • ISSU– (In Service Software Upgrade) relatively simple to scope, any real added value • Software patches ….. others ….

  4. Thank you • Valuable comments so far from: Al Morton, Ron Bonica, Ilya Varlashkin, Carlos Pignataro, Andrew Yourtchenko, Sarah Banks
