“…The most common convention distributed web server system is based on round-robin domain name resolution (RR-DNS), which assigns HTML document requests to web server [3]. The round-robin technique is useful specifically in the case that HTTP requests access HTML document of a standard size and the load and service rate of web servers are fairly comparable [4].…”

Abstract-This paper presents an analytical model and the way of simulation for distributing workload on a distributed web server system. The increase in the Internet traffic has also necessitated the conventional Domain Naming Service (DNS) to operate at a much lower efficiency. Among a number of problems associated with the DNS, a key problem has to do with the authoritative DNS not being able to process complete knowledge of the proximity. This makes the authoritative DNS less effective in monitoring server availability and routing incoming requests around failed servers. The workload distribution strategy on the other hand, keeps track of the state and health of the web server. This avoids connection delay due to, for example, a failed server, which can be temporarily by passed by workload distribution. From a modeling standpoint, the conventional DNS assumes equal queue size for each web server in a round-robin setting. Under load balancing, the queue size for each web server differs based on the probability of accessing that server. This probability is based on such factors as the geography, server health, server response, server threshold, session capacities, and the round trip time. In this paper, both conventional and global workload distribution strategies are developed and compared based on a finite set of practical traffic scenarios.Index Terms-Domain name server, entropy, workload distribution strategy, round-robin setting.

“…What is interesting about this form is the possibility that there exists an optimal value for the TTL parameter (the inventory re-order time). In previous work this TTL parameter has been set essentially by hand, without much insight into its functional role [8,11]. We would like to investigate this causal role of the TTL value more carefully below by testing DNS implementations against simulated traffic patterns.…”

Abstract. With many organizations now employing multiple data centres around the world to share global traffic load, it is important to understand the effects of geographical distribution on service quality. The Domain Name Service is an important component for global load balancing. Using controllable simulations, we show that wide area sharing can play an important role in optimization of response times when traffic levels exceed that which can be supplied by a local infrastructure. We compute the probability of being able to meet Service Level Objectives as a function of DNS caching policy (Time To Live), so that service providers can account for DNS error margins in Service Level Agreements.
