Trustworthiness management in sharing CDN infrastructure

Sharing Content Delivery Network (CDN) technologies such as CDN interconnection and cloud-based CDN have facilitated access to the huge volume of content in a cost-effective way. However, content distribution through shared CDN nodes is vulnerable to a wide variety of uncertainties, including unexpected node failure, intentional node disruption for maintenance or potential discrimination of content based on ownership. Trustworthiness can be considered as a key property to overcome the perception of uncertainty before delivering content through sharing CDN infrastructure and provide reliable broadcasting and telecommunications services. Establishing trustworthiness in sharing CDN infrastructure is a challenging task in the absence of the referenced framework. Therefore, we propose a trustworthiness management framework for sharing CDN infrastructure.
