Hi Greg, Thanks for your quick reply. I'm not sure how much help these comments will be in the development of the YANG model (which I intend to provide some feedback on separately), but here they are anyway. Editorial: ippmPDVMetricsGroup OBJECT-GROUP OBJECTS { pmForwardJitter, pmForwardJitterMaximum, pmReverseJitter, pmReverseJitterMaximum } STATUS current DESCRIPTION "Collection of one-way delay variation (jitter) metrics." ::= { twampGroups 5 } ippmReoMetricsGroup OBJECT-GROUP OBJECTS { pmForwardReordering, pmReverseReordering } STATUS current DESCRIPTION "Collection of one-way test packet re-order metrics." ::= { twampGroups 5 } The same oid is allocated for two objects. This can be resolved simply by bumping up the oid for ippmReoMetricsGroup and all subsequent members of twampGroups. Editorial: twampTest OBJECT IDENTIFIER ::= { twamp 2 } Since twampTest really provides a representation of the Server and Session-Reflector roles of RFC5357, it would perhaps have been better named twampServer. General: There is no way to configure more than one test session per control session via the controller, which is allowable by the protocol and potentially has good use cases. Similarly, on the server side, the ability to group the test sessions by the control session they belong to would be useful, along with providing access to properties of the control session, such as the far-end IP address and far-end TCP port.

However, in light of the recent publication of draft-cmzrjp-ippm-twamp-yang and its statement about progress on draft-elteto-ippm-twamp-mib being stalled, is it worth me articulating those comments? In other words, will there be any further updates to draft-elteto-ippm-twamp-mib? > > Thanks, > Rob >
