Abstract
Data flow in a communications network is controlled by a downstream node specifying the maximum average speeds of a plurality of data streams sent from an upstream node on a plurality of data paths.
Claims22
A system for controlling the flow of data in a communication network of the kind in which a plurality of data streams are sent from an upstream node to a downstream node via a respective plurality of data paths carried on a link connected between said nodes, comprising
- means for said downstream node to specify information concerning permissible speeds of said data streams on the respective paths, and
- means for said upstream node to update the speeds of said plurality of data streams when necessary in response to said information.
A system for aiding the control of the flow of data in a communications network having more than two nodes interconnected by links that carry data paths, and in which a data stream is sent from an upstream node to a downstream node on a data path that spans possibly one or more intermediate nodes, comprising
- means for the downstream node and each of said intermediate nodes to specify to an immediately preceding node along said data path information concerning the permissible speed of the data stream on the portion of said path carried by the link from said immediately preceding node, and
- means for said immediately preceding node to update the speed of said data stream when necessary in response to said information, whereby the speed of said data stream on said data path is controlled distributively by said downstream node and said intermediate nodes.
A method for controlling the flow of data in a communications network of the kind in which a plurality of data streams are sent respectively via a plurality of data paths from an upstream node to a downstream node, comprising
- the downstream node specifying information concerning permissible speeds of said data streams on the respective paths, and
- said upstream node updating the speeds of said plurality of data streams when necessary in response to said information.
