A Practice Guide of Predicting Resource Consumption in a Web Server

Optimum Software Aging Prediction and Rejuvenation Model for Virtualized Environment

“…The transmission delay of monitoring packets between service components and the AFD (Aging failure Detector) unit are chosen as the basic runtime metrics for aging detection [6]. Yongquan Yan proves that choosing a proper data set is more important than choosing a method for software resource consumption forecasting [7]. Some researchers have suggested rejuvenation based on the time estimation [8].…”

“…A-GARC algorithm executes crossover function to select the best host for accommodating aged VMs. The algorithm used for genetic algorithm (GA) based task placement or relocation is given as follows: Step- 1 Create VM and install applications on certain host node Step-2 Forecast software ageing probability based on aging indicator metrics Step- 3 Perform Initial mapping of VMs and connected hosts and then use it as initial population for GA Step- 4 Identify the aged hosts using Step-2 so as to avoid any probable SLA violation and conflict during rejuvenation Step- 5 Identify the list of VMs allied with each host node, which are not under migration, so that SLA performance violation could be avoided Step- 6 Perform aged VMs selection and retrieve the list of all VMs ready for migration Step- 7 Sort all VMs on the basis of its aging status Step- 8 Retrieve the complete active hosts possessing minimal workload and resource under-consumption Step-9…”

An Improved Nonlinear Multi-Objective Optimization Problem Based on Genetic Algorithm

“…About the same time the emergence of many multi-objective evolutionary Algorithms conference, the current evolutionary algorithm research has become in recent years, information science [4], artificial intelligence and computer science [5], one of the two major research focuses.…”

Web Spam Detection Based On Link Diversity and Content Features

“…When search engine indexes web pages according to user's request, it has to deal with a lot of web spam pages. So for the web search engines, it is one of the top challenges to combat with web spam [6].…”
