Software architecture for developing distributed fault-tolerant systems independent of the underlying hardware architecture and operating system. Systems built using architecture components are scalable and allow a set of computer applications to operate in fault-tolerant / high-availability mode, distributed processing mode, or many possible combinations of distributed and fault-tolerant modes in the same system without any modification to the architecture components. The software architecture defines system components that are modular and address problems in present systems. The architecture uses a System Controller, which controls system activation, initial load distribution, fault recovery, load redistribution, and system topology, and implements system maintenance procedures. An Application Distributed Fault-Tolerant / High-Availability Support Module (ADSM) enables an applications( ) to operate in various distributed fault-tolerant modes. The System Controller uses ADSM's well-defined API to control the state of the application in these modes. The Router architecture component provides transparent communication between applications during fault recovery and topology changes. An Application Load Distribution Module (ALDM) component distributes incoming external events towards the distributed application. The architecture allows for a Load Manager, which monitors load on various copies of the application and maximizes the hardware usage by providing dynamic load balancing. The architecture also allows for a Fault Manager, which performs fault detection, fault location, and fault isolation, and uses the System Controller's API to initiate fault recovery. These architecture components can be used to achieve a variety of distributed processing high-availability system configurations, which results in a reduction of cost and development time.

An apparatus is provided for analysis of a repair for a structure by identifying component parts of the structure that have common material properties and geometric constraints, and based thereon determining a generic repair component for the component parts that also have the common material properties and the geometric constraints. A set of loads are extracted from a loads model of the undamaged structure and redistributed in a loads redistribution model at a damaged or defective portion of the component part. The set of redistributed loads indicate loading incurred by the generic repair component under an external load. The apparatus then uses the redistributed loads to perform an analysis to determine a margin of safety of the generic repair component and, in instances in which the margin of safety is positive, outputs the material properties and geometric constraints of the generic repair component to a fabrication system for production thereof.

A wireless network in which wireless terminals associate with particular access points maintains information about the positions and associations of the terminals and calculates loads on access points. To provide increased bandwidth at a heavily loaded access point, terminals associated with adjacent access points are handed over to more distant access points, so that the adjacent access points become less active and generate less interference. The hand-over is initiated and carried out by the access points concerned, rather than by the terminal that is handed off. Loads can accordingly be balanced promptly and interference can be reduced.

The invention discloses a method for implementing load redistribution. The method comprises: a RAN node receives an initial direct transfer message, wherein the routing parameter type carried by the initial direct transfer message is of direct routing type; and the RAN node selects a servicing CN node from CN nodes in non-unloaded state when CN nodes in unloaded state exist in the belonging domain.

Additionally, the servicing CN node is selected based on the load balance principle with regard of the five situations when the routing parameter type is of direct routing type, thereby ensuring the load balance between the CN nodes.

Embodiments are directed to redistributing authentication requests among a plurality of authentication servers and to centrally managing authentication affinities among distributed servers using a secure channels affinity service. A computer system instantiates a secure channel management service configured to manage secure channel connections. The secure channel management service receives state inputs from currently deployed authentication servers. The authentication servers may be configured to queue authentication requests for transmission to authentication servers. The computer system determines that, based on the received state input, at least one of the secure channels is to be remapped to a different authentication server. The computer system also remaps the determined secure channels to distribute future authentication requests among the authentication servers. In some cases, the current state of an authentication proxy server is embedded in communications transmitted by the authentication server, such that the secure channel connections are managed using the embedded state information.
