Abstract
The network architecture of the content delivery network (CDN) and methods of the load balancing were examined in this paper. We have described the algorithm of end users’ request routing which allows selecting the optimum edge server to receive a content with maximum quality. The use of network system monitoring was offered. This system allows to efficiently assess the status of the network and promptly report possible problems. It was defined which parameters are needed to be monitored. Graphic dependencies of CDN networks efficiency, hit ratio and response time depending on resizing cache were presented as result of the simulation. The dependencies demonstrate an important feature which means that increasing of the cache size doesn’t allow an effective use of CDNs. However, server response time to end users’ requests depends on a size of the cache. It was established that the use of CDN gives an opportunity to significantly save bandwidth, reduce server response time and in that way to provide services with a satisfactory quality and optimal use of network resources.
