As virtualization becomes more and more popular, how to guarantee survivability of a virtual infrastructure (VI) over a wide-area optical network is increasingly important. In this paper, we approach the problem of survivable VI mapping (SVIM) from a few unique perspectives. One of the most distinguishing perspectives is that a large-scale regional failure could destroy one or more facility nodes...
Under the emerging paradigm of federated computing services (FCS), one can create multiple virtual infrastructures (VI), one for each distributed computing application or service offering. Each VI may consist of a number of geographically distributed computing clusters that are connected with a set of dedicated circuits. In general, a VI submitted by a user to the FCS provider is unmapped at the time...
