Document: draft-ietf-tsvwg-sctp-failover-14 Reviewer: Alexey Melnikov Review Date: 2015-12-23 IETF LC End Date: 2015-12-23 IESG Telechat date: (if known) N/A Summary: Ready with a couple of minor points that need to be clarified. Major issues: None Minor issues: In Section 5 However as [RFC4960] switchback behavior is suboptimal in certain situations, especially in scenarios where a number of equally good paths are available, an SCTP implementation MAY support also, as alternative behavior, the Primary Path Switchover mode of operation and MAY enable it based on users’ requests. Did you really mean "users" (human beings) and not "applications" (programs) here? I.e., is this something that needs to be exposed in APIs or User Interfaces. In Section 7.1: should new constants be defined with specific numeric values, in order to improve interoperability?
