Overview: This paper from Hewlett-Packard describes a secure network virtualization framework that helps realize the abstraction of Trusted Virtual Domains (TVDs), a security-enhanced variant of virtualized network zones. The framework allows groups of related virtual machines running on separate physical machines to be connected together as though they were on their own separate network fabric and, at the same time, helps enforce cross-group security requirements such as isolation, confidentiality, security, and information flow control. The framework aims at automating the instantiation and deployment of the appropriate security mechanism and network virtualization technologies.
