Abstract:
1. A method of controlling link parameter values for a multihop route involving at least two links in a multihop network, wherein said method comprises the steps of: a first computer-controlled node determining a parameter value common to all links along the entire multihop route based on a given end-to-end (ETE) transmit parameter constraint for the entire multihop route; and a second computer-controlled node assigning, for each of a number of said links, a set of the following three interdependent link transmit parameter values, each interdependent link transmit parameter value also being dependent on local link characteristics: wherein the three interdependent link transmit parameter values are based on said common parameter value and said local link characteristics; and the second computer-controlled node using the three interdependent link transmit parameter values when sending data over each of said links, wherein said method further comprises collecting link transmit parameter information related to the ETE transmit parameter constraint, forming an aggregated ETE transmit parameter value from the collected link transmit information, and comparing the aggregated ETE transmit parameter value in relation to the given ETE transmit parameter constraint, wherein said determining a common parameter value is controlled based on the result of said comparison, and wherein said method further comprises distributing said common parameter value to a number of nodes along the multihop route to enable each of said nodes to allocate said set of interdependent link transmit parameter values based on said common parameter value and said local link characteristics.
