Hash perturbation with queue management in data communication

A data processing system for hash perturbation with queue management in data communication, the data processing system comprising:

• a storage device including a storage medium, wherein the storage device stores computer usable program code;
• and
• a processor, wherein the processor executes the computer usable program code, and wherein the computer usable program code comprises:
• computer usable code for queuing, using a first set of queues corresponding to a first hash function, a set of data packets corresponding to a set of sessions in a data processing environment, the first set of queues forming a set of old queues;
• computer usable code for changing, at a first time, the first hash function to a second hash function;
• computer usable code for creating a second set of queues corresponding to the second hash function, the second set of queues forming a set of new queues;
• computer usable code for dequeuing, from a first old queue in the set of old queues, a data packet in the set of data packets;
• computer usable code for selecting, from a second queue in the set of old queues, a second data packet;
• computer usable code for computing a new hash value for the second data packet using the second hash function;
• and
• computer usable code for queuing the second data packet in a first new queue from the set of new queues such that the second packet is in position to be delivered first from the first new queue.
