Methods, devices, and computer-readable media for load balancing in port channels

A controller comprising:

• a storage configured to store instructions;
• and
• at least one processor configured to execute the instructions and cause the at least one processor to:
• identify a first port channel and a second port channel within a network to perform load balancing of network traffic across links of the first port channel and the second port channel, respectively, using a default algorithm;
• cause a first change from the default algorithm for performing load balancing of first network traffic transmitted by the first port channel to a first hash algorithm for the load balancing of the first network traffic, wherein the first port channel is within a wide area network (WAN) that supports Layer 2 connectivity over Layer 3 networks, and wherein the first hash algorithm calculates a hash based on an inner source media access control (MAC) address and an inner destination MAC address of a packet transmitted over the first port channel;
• cause a second change from the default algorithm for performing load balancing of second network traffic transmitted by the second port channel to a second hash algorithm for performing the load balancing of the second network traffic, wherein the second hash algorithm is different from the first hash algorithm and is determined based on analyzing characteristics of network data on a network segment of the second port channel different from a network segment of the first port channel;
• and
• load balance the first network traffic using the first hash algorithm for the first network traffic over the first port channel and the second hash algorithm for the second network traffic over the second port channel.

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor, cause the at least one processor to:

• identify a first port channel and a second port channel within a network to perform load balancing of network traffic across links of the first port channel and the second port channel, respectively, using a default algorithm;
• cause a first change from the default algorithm for performing load balancing of first network traffic transmitted by the first port channel to a first hash algorithm for the load balancing of the first network traffic, wherein the first port channel is within a wide area network (WAN) that supports Layer 2 connectivity over Layer 3 networks, and wherein the first hash algorithm calculates a hash based on an inner source media access control (MAC) address and an inner destination MAC address of a packet transmitted over the first port channel;
• cause a second change from the default algorithm for performing load balancing of second network traffic transmitted by the second port channel within the network to a second hash algorithm for performing the load balancing of the second network traffic, wherein the second hash algorithm is different from the first hash algorithm and is determined based on analyzing characteristics of network data on a network segment of the second port channel different from a network segment of the first port channel;
• and
• load balance the first network traffic using the first hash algorithm for the first network traffic over the first port channel and the second hash algorithm for the second network traffic over the second port channel.
