The emergence of Web-services as an open components supporting flexible and inexpensive set of distributed applications as well as exploiting them as a promising solution for integration with other application and providers of software-hardware resources is very much in demand. Using Web-services simplifies and enhances system functionality because of the availability of programs interaction with each other through Internet using open protocols. Thereby it is necessary to provide QoS provision issues such as distribution of request streams, enhanced efficiency of operations at peak loads. One of the ways to tackle these issues is to apply dynamic request distribution which ensures continuity of data transfer and processing ignoring crashes and equipment failures, redistribution of data flow to the available nodes in case of their loss. Abovementioned can be achieved using certain heuristics based on methods of Mathematical statistics and Probability modeling. Moreover, we provide analysis of methods and models developed for QoS provision.
