tailieunhanh - A comparative analysis on existing DNS performance measurement mechanisms

The software techniques provide burst of unrealistic data for limited time, restricting the scope of performance measurement and evaluation. Hardware data generation systems can be both expensive and inflexible. There is a need for more realistic DNS data traffic which can be used for flexible and cost effective performance measurement over a longer period for thorough evaluation. | International Journal of Computer Networks and Communications Security C VOL. 2, NO. 5, MAY 2014, 158–167 Available online at: ISSN 2308-9830 N C S A Comparative Analysis on Existing DNS Performance Measurement Mechanisms Ejaz Ahmad1 and Kashif Sarwar2 1 Ericsson Ltd, Middlesex University, London, United Kingdom 2 Cyber Age Ltd, London, United Kingdom E-mail: 1ejazahmad9@, 2kashif_sarwar78@ ABSTRACT DNS maps the complex IP addresses, making it crucial for internet communication for users and applications. DNS, an integral component of internet, is faced with many challenges. Enormous data growth and inherent security weakness demands continuous monitoring and performance measurement of DNS traffic. DNSSEC can improve security at the cost of DNS performance. This tradeoff needs to be evaluated before actual implementation. DNS performance measurement is critical for this evaluation. IPv6 will increase load on DNS exponentially, resulting in greater need for DNS performance evaluation. Despite the critical need for DNS performance measurement, very little research has happened on DNS performance measurement. Most of this little research has been done on client and authoritative layers of DNS. The most vulnerable and functionally important Caching layer performance measurement is hugely under researched. There are some software and hardware techniques available for DNS performance measurement. The software techniques provide burst of unrealistic data for limited time, restricting the scope of performance measurement and evaluation. Hardware data generation systems can be both expensive and inflexible. There is a need for more realistic DNS data traffic which can be used for flexible and cost effective performance measurement over a longer period for thorough evaluation.
