Patent ID: 7660896

Claim:
A machine-implemented method operative in a content delivery network (CDN) including a set of CDN servers, each CDN server provisioned with a manager process together with an application server on which one or more web applications are capable of being loaded and executed, comprising: for each CDN server and its respective manager process, identifying values for (i) a flit-capacity, and (ii) a memory capacity, where a flit is an arbitrary unit of work representing resource usage on the CDN server; using the values to generate a weighted mapping of web applications to manager processes for the set of CDN servers such that the flit and memory capacities for each CDN server are not exceeded, and wherein the weighted mapping of web applications to manager processes balances flits across the set of CDN servers; servicing requests at the CDN servers in proportion to the weighted mapping; and re-generating the weighted mapping of web applications to manager processes for the set of CDN servers if the flit values across the set of CDN servers becomes unbalanced.
