Configuring network nodes in communication network

A method of operation of a computing device in a communications network, the method comprising:

• generating a performance model for a plurality of network nodes of the communications network, wherein the performance model relates configuration parameters of a network node to at least one energy performance parameter of the network node;
• transferring the generated performance model to the plurality of network nodes;
• receiving information from the plurality of network nodes, said information indicating configuration parameters and at least one energy performance parameter of the respective network node;
• identifying a first network node of said plurality of network nodes as having a poor performance;
• identifying a second network node of said plurality of network nodes as having a good performance;
• and
• causing the first network node to operate with cloned configuration parameters of the second network node.

A method of operation of a network node in a communications network, the method comprising:

• receiving information from a cluster computing device, said information defining a performance model, wherein the performance model relates configuration parameters of the network node to at least one energy performance parameter of the network node;
• setting the configuration parameters of the network node based on said performance model;
• updating said performance model, based on the at least one energy performance parameter of the network node;
• and
• when instructed by said cluster computing device, sending said configuration parameters to at least one other network node, or
• when receiving configuration parameters from another network node, setting the configuration parameters of the network node to correspond to the configuration parameters received from the other network node.
