DNS Based Approach Load Balancing In Distributed Web Server System
Jyoti Vashistha · IOSR Journal of Engineering · 2013
In this paper, we consider the high level scheduling and load sharing properties offered by the Domain Name System, as implemented in popular DNS software packages.We explore the performance and capabilities of high-level DNS-based load balancing, where we draw special attention to the choice of caching policy (time-to-live) for DNS data.Further, we analyze the use of a database-supported DNS service for allowing highly dynamical query responses, and show that this approach has both potentially negative (single point of failure) and positive (improved balancing flexibility) properties.The objective of this paper is we discuss the performance requirements of the DNS, and argue that the robustness and performance of the DNS could be improved and also discuss the impact of TTL on response time in DNS I.
