METHOD, NODE AND DISTRIBUTED SYSTEM FOR CONFIGURING A NETWORK OF CDN CACHING NODES

The invention relates to a method, a server and a distributed system for configuring a network of CDN caching nodes. The network comprises a hierarchy of virtual CDN caching nodes collocated in a single layer of physical CDN caching nodes. Each physical CDN caching node runs a client-server application and at least one physical CDN caching node runs a server instance of the application. The server instance of the application is operative to detect a modification in the layer of physical CDN caching nodes and to receive traffic load information from the physical CDN caching nodes. The server instance is also operative to compute a new network configuration for the virtual CDN caching nodes based on the modification detected, the traffic load information received and locations of the physical CDN caching nodes and to configure the network of physical CDN caching nodes with the new network configuration.
