摘要:
A system for automated and optimized file transfers among devices in a network comprises a client configured to request a file transfer, a server configured to transfer the requested file to the client, and a scheduling module configured to schedule delivery of the file to the client. The scheduling module preferably schedules the delivery of the file to be completed by a deadline. In an alternate embodiment, the file is transferred to a device in the network that did not send the request. The file transfer may be requested by a user at the client or may be requested by a pre-fetch module of the client.
摘要:
Data transfer rates on a network are controlled in conjunction with TCP/IP protocols by limiting the available space in a receive buffer located on the receiver. Limits are generated by either moderating the rate that data is removed from the receive buffer or changing the receive buffer's size. Transfer rates are reduced to decrease the impact large transfers have on other network traffic and to reduce the total number of lost data packets. Reduced rates and priorities can be managed by scheduling systems.
摘要:
A system and method for scheduling transfers of data through a network, the system comprising a transfer module at each node in the network, the transfer module being configured to schedule data transfers according to available resources at each node. In one embodiment, the transfer module includes a scheduling module, a routing module, and an execution module. The scheduling module at each node evaluates a single hop request in view of objectives, such as a deadline, and the available resources at that node, for example transmit bandwidth, receive bandwidth, and storage space, all of which may change as a function of time.
