| 摘要 |
The present invention is directed to technology for employing one or more virtual nodes in a communications network to schedule data transfers. A virtual node receives a scheduling request for a transfer of data from a first node in the network to a second node in the network. The virtual node determines whether sufficient resources exist at the first node for performing the data transfer. In some instances, the virtual node creates a schedule for making the transfer, and the second node employs the schedule to reserve bandwidth for receiving the future transfer. In further embodiments, the virtual node arranges for the requested data to be delivered to the first node, so the first node's scheduled data transfer to the second node can be performed.
