Abstract
Methods and apparatus for load balancing across member ports for traffic egressing out of a port channel are provided herein. An example method according to one implementation may include: assigning a quantized value based on current load to each of the network ports in the port channel; receiving a data packet addressed to egress through the port channel; identifying a traffic flow with which the received data packet is associated; determining whether the identified traffic flow is a new traffic flow; and selecting one of the network ports in the port channel as an egress port. Selection of the egress port may be weighted according to the quantized value of each of the network ports in the port channel.
