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.
This paper is devoted to the solving the problem which occurs in cellular networks at times of peak busy hour when the radio resources are ended in one or more cells. Proposed method increases the availability of radio resources of mobile network through radio resources forced redistribution. Radio resources forced redistribution is transfer of a part of network load from congested sector to lower loaded sector. This is done by transferring subscriber load (forced handover) between closely-spaced sectors within the common coverage area.
Concept content delivery network (CDN) system and load balancing mechanisms were considered in this paper. The main task of the CND network — providing the qualitative information delivery to the end user. Content Delivery Network (CDN) — is a geographically distributed network, that contains a number of content servers and routers. As a rule, it consists of a main node (Origin), and caching nodes (Edges) — points of presence, which can be located in various parts of the world. All content are stored and updated on the Origin server.
