Embodiments of the present systems and methods may provide a consistent hash function that provides reduced memory use and complexity, reduced computational complexity, and relatively low numbers of keys that must be reshuffled compared to current techniques. For example, in an embodiment, a computer-implemented method for controlling computing resources may comprise storing a set of labels of potential resources comprising a plurality of labels of working resources allocated to actual resources and a plurality of labels of reserved resources available to be allocated, generating an initial assignment to one of the set of labels of potential resources, when the assignment to one of a set of labels of potential resources is to one of the labels of reserved resources, reassigning the request to another label of a resource selected from a subset of the labels of potential resources, and repeating the reassigning until the request is assigned to a label of a working resource.

Fast, low memory, consistent hash using an initial distribution

An embodiment of the invention may include a method, computer program product, and system for data transfer management. The embodiment may include receiving a data packet from a client computing device. The received data packet is part of a data flow. The embodiment may include determining that the received data packet is not part of a data flow tracking list. The embodiment may include computing a current mapping value for the received data packet. The embodiment may include determining that a global system state of expecting change exists. The embodiment may include computing an expected mapping value for the received data packet. The embodiment may include determining that the expected mapping value is not equal to the current mapping value. The embodiment may include adding the data flow to the data flow tracking list. The embodiment may include forwarding the received data packet according to the current mapping value.

Distributed affinity tracking for network connections

An embodiment of the invention may include a method, computer program product, and system for data transfer management. The embodiment may include receiving a data packet, by a first server, from a load balancer. The received data packet is part of a data flow. The embodiment may include determining, by the first server, whether the received data packet is part of an existing data flow connection served by the first server. Based on determining that the received data packet is not part of an existing data flow served by the first server, the embodiment may include determining, by the first server, whether the received data packet is part of a new data flow connection. Based on determining that the received data packet is not part of a new data flow connection, the embodiment may include notifying, by the first server, the load balancer.
