主题: [bess] review of draft-www-bess-yang-vpn-service-pm

As abstract said:
“
This document defines a YANG model for
   Network and VPN Service Performance Monitoring that can be used to
   monitor and manage network performance on the topology at different
   layer or the overlay topology between VPN sites.
“
I believe YANG model described in this draft can be used to monitor network performance or can be used to monitor VPN performance.
  This two performance monitoring are two separate functionalities.
[MW]: Agree.

  Section 4 provide two layered topology which can be used to monitor network performance in the overlay topology and monitor in the service topology Separately which is good.
[MW]: Thanks.

  Section 6.1 describe network level parameter such as vpn topology, svc topo type, I think these network level parameters are not needed when monitoring network performance.
[MW]: The section 6.1 introduce how to augment the ietf-network model to support VPN performance monitoring.
For monitoring network performance, IMHO,  the section 6.1 can be ignored since the network-type and l3-topology-attributes have been defined in RFC8345 and RFC8346.

Please make this clear in the text.
[MW]: I’d like to add some text to introduce how to support network performance monitoring.
