Virtual data center allocation with bandwidth guarantees

摘要

A virtual data center allocation architecture with bandwidth guarantees that provides for the creation of multiple virtual data centers from a single physical infrastructure. The virtual data center allocation is accomplished in three steps. First, clusters are created from the servers in the physical infrastructure. Second, a bipartite graph is built to map the virtual machines to the servers located in a particular cluster and finally a path is calculated between two virtual machines. The virtual data centers may be dynamically expanded or contracted based on changing bandwidth guarantees.

主权项

1. A system comprising:
a virtual data center manager in a physical data center for allocating bandwidth and allocating a plurality of routing paths for a plurality of virtual data centers, the physical data center comprising a plurality of servers and a plurality of switches; the plurality of servers configured to perform packet classification and to define a particular path of the plurality of routing paths with source routing; and the plurality of servers and the plurality of switches configured to implement priority queuing for the plurality of routing paths.
