Only tracing require adding meta data to packet and that's also protocol specific.

Path Packet Counters Path-packet-counters feature is part of the passive OAM feature set, where the meta-data carried is to be interpreted by the passive OAM domain's encapsulating and decapsulating nodes. Sequence numbers are the main meta-data added and can be used to detect packet loss, packet reordering or packet duplication. David> Can we have more details on that : - What is the mechanism ? - what is the packet format ? +++DK: It's real data traffic determined by configured policy matching traffic. 3.3.3 Proof of Transit Proof of transit feature is part of the passive OAM feature set, where the path or the service chain is verified. Service or path verification uses methods like nested hashing or nested encryption of the meta-data. By definition of a service chain or a path, some of the nodes in the domain participate and some do not. David> the same ? +++DK: It's real data traffic determined by policy matching the traffic.
