Network optimization for mitigation of crosstalk between network links

A network controller, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to:
• receive link metrics for a plurality of network links on a plurality of cables between network devices in a communication network, the link metrics including metrics indicative of crosstalk experienced by network links among the plurality of network links on the plurality of cables, the plurality of cables comprising respective cables having maximum bandwidth ratings,
• determine, based at least in part on the link metrics, respective link settings for respective network links among the plurality of network links, the link settings for a first respective network link determined based on i) link metrics for the first respective network link and ii) effects that transmission of signals on the first respective network link has on concurrent transmission of signals on other ones of network links among the plurality of network links, to mitigate crosstalk experienced by the respective network links as a result of transmission of signals in at least some of the network links at baud rates that correspond to bandwidths that exceed maximum bandwidth ratings of respective cables of the corresponding ones of the network links, and
• cause configuration of the respective network links based on the link settings to optimize performance across the plurality of network links in the communication network.
