Density-Based Server Placement for Collaborative Virtual Services

Abstract

The boundaries on different domains are blurring as corporations and infrastructure providers are collaborating to offer end-to-end services over the networks and infrastructures of various network, service, cloud, content delivery and other infrastructure providers as well as the customer premises. To capture opportunities and shine in competitive service market, infrastructure and service providers need to excel in addressing the changing customer requirements and in the operations and management of the resources. They should welcome effective collaboration with other network and infrastructure providers in delivering quality services to customers. Effective sharing of the infrastructure resources is essential in meeting the customer demands and reducing the cost. Server placement problem for end-to-end virtual services becomes a crucial optimization challenge for providers in such collaborative environments. We formulate the collaborative virtual server placement problem and suggest density-based clustering algorithms to address this problem.
