Abstract: Under growth of the Internet and increasing volume of video and other large - scale multimedia contents, key challenge is related to delivering the content to users. According the problem Content Delivery Network (CDN) and Peer-to-Peer (P2P) have been proposed and deployed. CDN and P2P have complementary advantages: high scalability and low cost of P2P and high reliability and good stability within CDN. As a result different hybrid approac hes were proposed. In the article we’ll assume CDN as basic architecture and that one user can connect to several content servers in same time (in parallel). One of the important problems that are solved in the network is request routing which combines choosing of the content servers (for sourcing) and traditional routing from the chosen servers to the user. The paper proposes a mathematical model which allows to formulate the problem of request routing in hybrid content delivery network as optimization problem and to resolve it in concordance with the traditional task of multipath routing in transport telecommunications network. In order to realize rigid guarantees proposed mathematical model includes tensor QoS-condition.
