Hi Yuhei, 

A victim (target) can be identified by one or + target-prefixes. 

The YANG module allows to return many pre-mitigations; each with a target clause:

             +--rw pre-mitigation* [telemetry-id]
                +--rw telemetry-id                     uint32
                +--rw target
                ...
                +--ro attack-detail
                   ...
                   | 
                   +--ro top-talker

A server can aggregate top-talkers for all targets of a domain, or when justified, send specific information (including top-talkers) per individual targets.

Cheers,
Med
