Strubytskyi R. Methods and algorithms for construction of cloud data storages based on distributed telecommunication systems.

The thesis is devoted to development of elements of the telecommunications network architecture to transfer data through cloud storages. The model cloud data storage was improved, methods and protocols for cloud storage access were researched. The basic approaches and problems of cloud storage implementing were analysed. Methods for transporting data in distributed telecommunications systems were analyzed. New architecture of cloud storage made it possible to improve productivity and fault tolerance of the system as a whole. The transport protocol was created which based on UDP for regional distributed networks. The method of multi-protocol data transfer in cloud storages was developed, which has higher productivity as opposed to the method of selecting a one protocol. The method of multiplexing data from different data sources in the cloud storage got the further development. This method allows to use available data channels more effectively by their utilization as opposed to the method of load balancing. The method of choosing gateway by complexity of request was established, which provides a short way from user to the data storage system. Developed the cloud data storage based on the proposed architecture, protocol, and methods.
