Both the agent and manager implementors want fixed sized numbers to save time and memory, and not have to support more than one way of encoding a given data type. Unbounded integers are really not okay for data models. This is one difference between an info model and a data model, something Juergen knows all about. We standardize data models for NM for SNMP, and we should do the same thing for NETCONF. The value of a standard is in its deployment, after all. > /js > Andy _______________________________________________ NGO mailing list NGO@ietf.org https://www1.ietf.org/mailman/listinfo/ngo
