Abstract

Existing Content Delivery Networks (CDNs) exhibit the nature of closed delivery networks which do not cooperate with other CDNs and in practice, islands of CDNs are formed. The logical separation between contents and services in this context results in two content networking domains. In addition to that, meeting the Quality of Service requirements of users according to negotiated Service Level Agreement is crucial for a CDN. Present trends in content networks and content networking capabilities give rise to the interest in interconnecting content networks. Hence, in this paper, we present an open, scalable, and Service-Oriented Architecture (SOA)-based system that assist the creation of open Content and Service Delivery Networks (CSDNs), which scale and supports sharing of resources through peering with other CSDNs. To encourage resource sharing and peering arrangements between different CDN providers at global level, we propose using market-based models by introducing an economy-based strategy for content replication.
