9.2. m-Level Architecture

In this section, we will generalize our two-level to a multi-level architecture. With the m-level architecture, requests are submitted to a distributed server (DS) consisting of a number of centralized SM servers connected to each other via dedicated communication links [155], [16], [123]. Upon the arrival of a new request, the system has to locate a node (server) that has the requested object and the required resources to deliver the object. To deliver the SM object, with a consumption rate Rc, from the source Ns to the user N0, the system needs to establish a path (Figure 9.8).
