Load balancing of activities on physical disk storage devices is accomplished by monitoring reading and writing operations to blocks of contiguous storage locations on the physical disk storage devices. A list of exchangeable pairs of blocks is developed based on size and function. Statistics accumulated over an interval are then used to obtain access activity values for each block and each physical disk drive. A statistical analysis leads to a selection of one block pair. After testing to determine any adverse effect of making that change, the exchange is made to more evenly distribute the loading on individual physical disk storage devices.

A method for routing packets in a multipath network of nodes balances the loading of system resources while guaranteeing a FIFO network (i.e., First In First Out). Acyclic directed graphs based on local network information are used at each node with routing bias tables that allow for local preferences. A randomizing function may be used throughout the network to allow uniform utilization of system resources. A normalizing function may be used throughout the network to reduce bit operations in routing packets.

Systems and methods are provided that may be employed in a network environment to implement load balancing for multi-network interface controller (NIC) teaming applications using pause frame flow control communications received at an information handling system in situations where a given data path through a given NIC of the information handling system and a corresponding network switch is heavily loaded or otherwise congested relative to one or more other more lightly loaded data paths through other NICs of the information handling system and their corresponding network switches.

A method, system, and program for redirecting client connection requests among sockets providing a same service are provided. An application requests multiple sockets from a kernel. In addition, the application generates a socket call option to bind the sockets to a particular port number and passes a list of the sockets to the kernel, where the list indicates that the sockets will all provide access to server systems providing the same service. In response, the kernel sets up the sockets, bound to the same port, and set to reference one another. Then, when a connection request is received for a first socket in the list with a queue that is full, the kernel redirects the connection request to a second socket in the list with available queue space. Thus, rather than drop the connection request from the first socket when it lacks available queue space, the connection request is redirected to another socket providing access to the same service.

Aspects comprise a ray shooting method based on the data structure of a uniform grid of cells, and on local stencils in cells. The high traversal and construction costs of accelerating structures are cut down. The object's visibility from the viewpoint and from light sources, as well as the primary workload and its distribution among cells, are gained in the preprocessing stage and cached in stencils for runtime use. In runtime, the use of stencils allows a complete locality at each cell, for load balanced parallel processing.

A method for improving cell load balance in a cellular network and an associated user equipment (UE) are provided to improve cell load balance of the cellular network in a more flexible and effective manner. The method is used in the UE, and comprises receiving a first priority set and a second priority set from the cellular network and applying one of the first and second priority sets when selecting a new serving cell from the cellular network. Each of the first and second priority sets assigns a selecting priority to at least one carrier frequency or radio access frequency of the cellular network

A system and method for employing a key exchange key to facilitate secure communication is provided. The key exchange key can be employed, for example, to encrypt and/or decrypt dialog session key(s) that are used to encrypt and/or decrypt message(s) that form a dialog between an initiator system and target system. In one example, a key exchange key is unique to a service pair, while a dialog session key is unique to a particular dialog between the service pair. The system can facilitate end-to-end encryption of message data in a dialog—the message data is encrypted at one dialog endpoint and not decrypted until it reaches the other dialog endpoint. The system can be employed to facilitate secure dialog with minimal performance overhead when compared with conventional system(s). Optionally, the system can facilitate load balancing (e.g., among deployed instances of a service). In this example, secured dialogs to a service can be location transparent so that a dialog targeted to a service can be able to talk to any instance of the same service transparently without any additional security setup. The system employs both public key/private key asymmetric encryption technique(s) and symmetric encryption technique(s) to authenticate and secure information exchanged between an initiator system and a target system.

An invention enables network traffic rerouting, while avoiding the necessity of traffic to pass via a cluster's master node. By doing so, neither the master node, nor its communication link become a critical failure or load point, thus disrupting the cluster performance. At first a client sends a packet a certain server of the cluster. If the client is redirected, said server adds a redirection header, defined by a new redirection protocol, to the packet, and returns the packet to the client. A service address and a redirection flag are placed in the header. The client receives the packet with the redirection header and connects to the target server whose address is in the header. From then on, the target server handles the client's packet and the whole transmission related to it.
