According increasing popularity and volume of multimedia and other contents, content delivery networks (CDN) have been proposed and deployed. One of the important problems that are solved in the CDN is request routing which combines the content server choosing and traditional routing from the chosen server to the user. The paper proposes a mathematical model which allows to formulate the problem of request routing in CDN as optimization problem and to resolve it in concordance with the traditional task of multipath routing in transport telecommunications network.
Keywords: content delivery network, request-routing, mathematical model
