A server and method of its operation adapt the number of server applications within the server. The server is connected to a computer network. The server comprises one or more active server applications, a load detector, an inactive additional server application and an allocator. The load detector, which may be part of a load balancer, is connected to the one or more server applications and the computer network. The allocator is connected to the load detector and the additional server application. The allocator causes the additional server application to activate in response to a load condition. The method measures a load on the server, detects when the load exceeds a threshold and, in response thereto, activates an additional server application on the server. Optionally, the method also detects when the load is less than a deactivation threshold, and in response thereto, deactivates the additional server application. Also disclosed is a system comprising a plurality of computers, one or more connections to one or more servers, and a module. Each of the computers is capable of hosting a server application. The module is connected to the: computers and the connection(s). The module receives a request for an additional server application from one of the servers. Such a request may, for example, be generated when the server is experiencing a surge. In response to the request, the module activates the server application on one or more of the computers so as to support the requesting server.

A system and method are disclosed for enhancing the visibility and ensuring the correctness of terrain and navigation information on aircraft displays, such as, for example, continuous, three-dimensional perspective view aircraft displays conformal to the visual environment. More specifically, an aircraft display system is disclosed that includes a processing unit, a navigation system, a database for storing high resolution terrain data, a graphics display generator, and a visual display. One or more independent, higher precision databases with localized position data, such as navigation data or position data is onboard. Also, one or more onboard vision sensor systems associated with the navigation system provides real-time spatial position data for display, and one or more data links is available to receive precision spatial position data from ground-based stations. Essentially, before terrain and navigational objects (e.g., runways) are displayed, a real-time correction and augmentation of the terrain data is performed for those regions that are relevant and / or critical to flight operations, in order to ensure that the correct terrain data is displayed with the highest possible integrity. These corrections and augmentations performed are based upon higher precision, but localized onboard data, such as navigational object data, sensor data, or up-linked data from ground stations. Whenever discrepancies exist, terrain data having a lower integrity can be corrected in real-time using data from a source having higher integrity data. A predictive data loading approach is used, which substantially reduces computational workload and thus enables the processing unit to perform such augmentation and correction operations in real-time.

A routing protocol for a multicasting network, such as an ad hoc network, employs alternate tree or path computation algorithms that continually compute backup trees or paths that can be employed to replace failed trees or paths. The sets of alternate multicast trees or paths are preferably pre-calculated before a first tree or path fails to minimize delay in replacing a failed tree or path. Preferably, the algorithms are designed to compute the alternate multicast trees or paths in such a manner that they are maximally independent of the original set of trees and paths to minimize correlation between the original trees or paths and the replacement trees or paths and to possibly increase the useful time of the calculated trees. This helps insure that the replacement trees or paths will not be likely themselves to fail soon after failure of the original trees or paths.
