Mechanism Analysis and Quantitative Evaluation to Improve Network Availability
Tian Liqin · Journal of North China Institute of Science and Technology · 2011
With the growing popularity of network applications,increasing costs and effects caused by the interruption of network system is very clear.DoS(Denial of service) is very rampant now,although availability can't prevent denial of service attacks,availability is available to reduce the impact of such attacks and it allows the system to normal operation.This paper discusses the concept of network availability,evaluation criteria of Network availability mechanism,and four mechanisms to improve network availability and compared between four mechanisms.Finally,the formula and examples of quantitative assessment network availability is given,which lay to enhance network availability based on the theory and practice.
