Consistent flow assignment in load balancing

Abstract:

A device may receive first information identifying multiple server devices and second information identifying multiple flows. The device may assign the multiple flows to the multiple server devices in a first order. The device may store the second information in multiple data structures to record the assignment of the multiple flows to the multiple server devices. A data structure, of the multiple data structures, may correspond to a respective server device of the multiple server devices. The device may receive an indication that a server device has been added to, or removed from, the multiple server devices after storing the second information. The device may reassign a subset of the multiple flows in a second order using third information identifying an order in which the multiple flows were assigned to the multiple server devices. The second order may be different from the first order.
