IEEE 802. 17 Resilient Packet Ring Draft D 0. 2 Section 1 Comment Resolution May, 2002 Ottawa, Canada ra_sultan@yahoo. com May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Clauses 1 – 4 and Annex A • Intro material derived from clauses – Due on same date as other clauses – Follows that intro always lags by one cycle (2 months) • exceptions when material provided early to editor • Clause 1 provides an overview of the specification – Some text too detailed and will be adjusted – Reflects normative text of other clauses • Technical decisions not made in the overview May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Statistics • 50 technical non-binding – 1 rejected – 29 accepted-modified – 23 accepted • 49 technical binding – 5 referred to section 0 (and resolved) – 7 rejected – 25 accepted modified – 8 accepted • 69 editorial May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Rejected / Referred • Rejected – Disallow ‘jumbo’ frames – Incorrect comment on ‘ringlet’ figure – Mandatory wrapping • Five items referred to chief editor – Notation will be moved to clause 3 (will move for change to ‘Terms, Definitions, and Notation’ – Should, shall, etc. referenced in Style Manual May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Significant Resolved Issues • Frame size 9216 (jumbo) as specified in D 02 C 8. 1 (11) • Least cost vs. shortest path / ring selection by client or MAC (8) • Classes A 0, A 1, B, C from RAH (7) • Circumference, not span (4) clause? • Editor’s questions (4) no action needed • Maximum number of stations on ring (3) clause? • Remove HOL blocking reference (3) • Ringlet naming (3) (eg. CW, CCW) clause? Chief editor? • Intent is to be lossless (3) (avoid specifying conditions) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Significant Resolved Issues • Describe multicast operation (4) • Delete reference to cut-through (4) • Delete material on reservation and provide editors’ note until defined (4) clause ? • Reject mandatory wrapping (conflicts D 0. 2) (1) • Remove reference to authentication/encryption (1) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Editorial In Nature • Remove unnecessary NOTE describing ‘fairness’ (2) • Fairness algorithm doesn’t restrict traffic (1) • Not all fairness message hop-by-hop (1) • RPR header terminology included in overview when adopted in clause 8 (1) • Correction in Qtag description (2) • Remove Qtag/CID from features list as too detailed. (1) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Editorial in Nature • • • Omit justification for header checksum (2) Additions/corrections to notation (2) Editors’ note on reference to OIF docs (1) Add steering for multicast when available (1) Add HEC and IOP to acronyms (understood that IOP may change) (2) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Editorial in Nature • • • Picture improvements (3) Provisioning terminology included when approved (1) Correct description of allowed rate (1) Clarification of delay properties (1) Header clarifications (2) Move notation subclause to clause 3 (1) Add c-code reference to references (1) Remove text regarding network layer as client (1) ‘Looping’ replaced by ‘indefinite circulation’ (1) Description of insert, strip, etc. (1) (will edit into overview as appropriate) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan

Editorial in Nature • Specify ‘fairness’ as ‘weighted fairness’ (1) Correct definition of ‘reclaimable’ (1) • Remove incorrect reference to leaky bucket (just refer to policing) (1) • Replace description of “uncommitted and reclaimable” from approved text (1) • Remove “uncommitted and reclaimable” as too detailed for features list (1) May 9, 2002 IEEE 802. 17 RPRWG Bob Sultan
