Document: draft-ietf-ippm-multipoint-alt-mark-06 Reviewer: Linda Dunbar Review Date: 2020-03-05 IETF LC End Date: 2020-03-06 IESG Telechat date: 2020-03-12 Summary: This document is to expand P2P flows marking methodology to measure unicast flows in multipoint-to-multipoint network. The mechanism is quite interesting. However, I do have some questions: Page 9 (Section 5: Multipoint Packet Loss): Second paragraph stating that "the sum of the number of packets on all ingress interfaces equals the number on the egress interfaces for the monitored flow". how to measure? with all nodes having different timer, it would be difficult to quantify the time period. At any given time T, egress node may count packets entered at T-x. Where to draw the line? packets may traverse different routes through the network, and can take different time. Section 6.1 Algorithm for Cluster Partition: How do you partition the cluster if the Application ingress the network via different nodes? Major issues: None Minor issues: None Nits/editorial comments: Page 5: first sentence on the policies to classify flows: should allow additional conditions that are not in the packet header as part of matching criteria Thank you very much.
