This paper describes a two-level simulated annealing heuristic for the joint problem of object
placement and request routing in a Content Distribution Network (CDN) with constraints
pertaining to server capacity and end-to-end object transfer delay. A CDN is a technology that
is used to eciently distribute electronic content throughout an existing network. The two-level
solution procedure is composed of an exterior and an interior simulated annealing algorithms.
Computational experiments are conducted by comparing the proposed procedure with several
truncated exact solution algorithms on randomly generated Internet topologies.
