Abstract

The domain name system (DNS) is an existing and implemented network service in Internet providing host and service reachability, which is essential to every IP connection setup. Merge of mobile networks with Internet results in large flow of frequent updates to the DNS database, which is a threat for DNS database consistency, because of strong caching it uses. Even though DNS wasn´t originally designed for networks supporting host mobility, it gets enabled, if caching of resource records, carrying mobile host´s locator information, is disabled by setting the time-to-live (TTL) field to 0 and by enabling dynamic DNS updates from mobile hosts to authoritative name servers. In this paper we are interested in the impact of TTL value 0 on DNS system performance. Based on the modeling of DNS caching behavior, we have a quantitative evaluation of the TTL value 0 impact on DNS performance of the mobile enhanced Internet
