摘要：The Internet has experienced a phenomenal growth as a result of increasing demands for contents, content distributions and other services. CDNs have evolved as cooperative and collaborative groups of networks over the Internet where contents are replicated over the surrogate servers for efficient delivery performance to the clients and improved service cost to the CDN providers. However, a CDN is limited in terms of Point of Presence (PoP) and scalability. This work is concerned with content object replication among peering CDNs. It provides an analytical model for the replication problem in terms of a constrained optimization problem subject to a mix of QoS
