NETWORK PATH SELECTION USING BANDWIDTH PREDICTION

摘要

In an embodiment, a system routes a new data stream from a source to a destination through a plurality of forwarding devices interconnected with links. The system includes a control device that receives a request to create a path through the plurality of interconnected forwarding devices for a new data stream and determines a type of the new data stream. A data flow database stores historical usage characteristics of data streams having the determined type. A path computation module determines, based on the historical usage characteristics of data streams having the determined type, the requested path through plurality of interconnected forwarding devices from the source to the destination.

主权项

1. A computer-implemented method for routing a new data stream from a source to a destination through a network including a plurality of forwarding devices interconnected with links, comprising:
(a) receiving, at a control device, a request to create a path through the plurality of interconnected forwarding devices for a new data stream; (b) determining a type of the new data stream; (c) determining, based on the determined type, historical usage characteristics of data streams having the determined type; (d) determining, based on the historical usage characteristics of data streams having the determined type, the requested path through the plurality of interconnected forwarding devices from the source to the destination; (e) for respective forwarding devices along the path, determining a routing table indicating which port of the forwarding device to route data from the new data stream along the path determined in (d); and (f) for each of the respective forwarding devices, transmitting the routing table determined in (e) to configure the forwarding device.
