SYSTEM FOR PROTECTION AGAINST DDOS ATTACKS

A method is presented that enables a server to make use of client or third party resources. The client request data contains data about the network location of the client. The server may store this location data of each client. Before or after execution of the request, the server determines if the server is in or close to an overload situation. If the server is not in an overload situation, no further changes are needed. If the server is in or close to an overload situation, the server selects a new location in the network from the database with all client locations. The server allocates a new instance of the server function at a resource provider on (or close to) this new location. The server may select one or more clients from the database. The selected clients are transparently redirected to the offloaded server function. Subsequent requests from clients are handled by the offloaded server function. The offloaded server function employs the same functionality and thus may decide to offload a server function to another network location.
