Abstract
The work is devoted to the increasing quality of services in software-Defined Network by modifying the resource allocation during service provision and services' replication techniques. The well-known replication techniques are analyzed in the work. The result of the analysis shows that existing replication techniques that are used in distributed networks should be revised with the purpose to improve their effectiveness and as a result, increase the availability of services. With the aim to increase the effectiveness of replication techniques in software-defined networking the solution of next tasks are proposed: determining the decision about start replication procedure based on simultaneously increasing of service popularity and degradation of quality of service; determine the required minimum number of replicas and their allocation in the network based on intensive of incoming customers’ requests; checking the consistency of new replica of service with almost existing in the network. The complex method of dynamic service replication that is based on this particular solution is proposed. The model of complex services provision is also proposed in the work. The proposed model allows to analytically analyze the value of each monatomic service in complex solution. The case of using the proposed model of the monatomic services that included in complex service can be preplaced by the service with better quality characteristics.
