The new IETF protocol ENUM uses the DNS to bind existing phone numbers into set of information's (email address, SIP phone number etc.). Success of ENUM will depend on whether the DNS can achieve a performance similar to the database used in classical voice services. In order to study the DNS performance we designed a new way to measure and model a single DNS server behavior. We also modeled and measured the IP links connecting the DNS devices: Resolver, Cache server and Authoritative servers. Finally we created a simulation model which enables us to simulate ENUM traffic. We then use the parameters obtained from the previous two models as input values into this simulator. The numerical results obtained from the simulation, was compared to real measurements in order to validate the global model. We plan to use the simulator to study different scenarios by varying different parameters. This will lead to recommendations of the new ENUM protocol to achieve the best performance.
