Performance driven software defined networking

A method for configuring a network, comprising:

• receiving performance data with respect to a first time period for communication pathways between a local router and routers in a core network, the performance data including a measured at least one of a delay, jitter, and a frame loss ratio of a class of service during the first time period;
• comparing at the least one of a measured delay, jitter, and the frame loss ratio with a corresponding threshold value in a first set of thresholds to determine a primary tunnel and a secondary tunnel;
• in response to a comparison between the at least one measured delay, jitter, and the frame loss ratio and the corresponding threshold value in the first set of threshold values, setting, by the local router, a first tunnel delay threshold and a second tunnel delay threshold to configure the primary tunnel and the secondary tunnel, respectively, from the communication pathways, wherein the first tunnel delay threshold includes a lesser value than the second tunnel delay threshold;
• measuring the at least one of the delay, jitter, and the frame loss ratio of the class of service during a second time period;
• and
• in response to a comparison between the at least one measured delay, jitter, and the frame loss ratio of the class of service during the second time period with the corresponding threshold value in a second set of threshold values, reconfiguring allocations of data streams in the primary tunnel and the secondary tunnel that were configured from the communication pathways during the first time period.

One or more computer-readable storage media storing instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• monitoring performance of communication pathways between routers in a core network and a local router, with respect to a first time period and via performance measurement pipes configured to include multiple data streams, the monitoring including independently measuring each of key performance indicators of a class of service during the first time period;
• comparing the at least one of the measured key performance indicators with a corresponding threshold value in a first set of thresholds to determine a primary tunnel and a secondary tunnel;
• setting a first tunnel delay threshold and a second tunnel delay threshold for communication pathways to configure the primary tunnel and the secondary tunnel, respectively, based at least on a comparison between the at least one of the measured key performance indicators and the corresponding threshold value in the first set of thresholds;
• measuring the at least one of the key performance indicators of the class of service during a second time period;
• comparing the at least one of the measured key performance indicators of the class of service during the second time period with a corresponding threshold value in a second set of thresholds to determine allocation of data stream flows of the class of service in the primary tunnel and the secondary tunnel that were configured from the communication pathways during the first time period;
• and
• allocating the data stream flows to the primary tunnel and the secondary tunnel based at least upon a comparison between the at least one measured key performance indicator of the class of service during the second time period with the corresponding threshold value in the second set of thresholds.
