     16== Requirements for Management of Timing Protocols ==
     17At IETF-92 the issue of requirements for management of timing distribution protocols was raised,
     18and it was suggested that we use this wiki to propose issues that need to be addressed.
     19
     20First one needs to consider the mechanism used to distribute the management information
     21i.e., native mechanisn inside the timing protocol, use of a standard management protocol (e.g., SNMP, netconf, restconf), etc.
     22
     23Next one should address the data modeling language (MIB and YANG being the 2 prime examples).
     24
     25One should also realize that there are at least 2 different actors that require different treatment, master/servers vs. slave/clients. There may be other types of "clocks" as well, including boundary clocks and transparent clocks.
     26
     27Regarding content, there are two kinds of parameters in timing mangement, namely configuration and performance monitoring. Configuration information includes things like the list of master/servers a slave/client should be observing, IP addresses, packet rates, modes and feature set to be used, stratum level of a master/server clock and from whom it received timing, security mechanisms, etc. Monitoring information includes ToD and/or frequency accuracy (if can be ascertained by comparison to a known reference), observed PDV, dispersion, etc. I am not sure that the requirements need to include an exhaustive list.
