A cluster system and method accesses from an internet network, a network server within one or a plurality of clusters, each cluster being identified by a single cluster public Internet Protocol (IP) address. The cluster system has a plurality of network servers organized in one of a plurality of clusters and a network load balancer system for selecting a destination network server in a cluster. Each cluster has one or a plurality of identical network servers, the network load balancer system being connected on one hand to an access routing device and on another hand to the plurality of network servers through a private network server subnet. The method includes the steps of at initialization time, on each network server defining, as a non-advertising alias, in an interface table, the public IP address of each cluster to which the network server belongs, and upon reception, by the network load balancing system, of a datagram having an IP header including a destination IP address field and a medium access control (MAC) header including a destination MAC address field, selecting a destination network server within the cluster corresponding to the cluster public IP address identified in the destination IP address field of the datagram IP header, replacing the destination medium access control (MAC) address field of the datagram MAC header by the MAC address of the selected destination network server, and sending the datagram through the private network server subnet, using the MAC address of the selected destination network server. Upon reception, by the destination network server, of the datagram sent by the network load balancing system, the MAC address in the destination MAC address field of the datagram MAC header is identified as being the MAC address of the selected destination network server, and the IP datagram is processed if the identified cluster public IP address in the destination IP address field of the datagram IP header, is defined as a non-advertising alias in the interface table of the destination network server.

Systems, methods, computer-readable media, and graphical user interfaces for presenting search results having collapsed domains are provided. A search result obtaining module obtains search results based upon a received query. Upon obtaining the search results, search results having the same domain are associated with one another. Thereafter, search result clusters of associated search results are formed. In some embodiments, the search result clusters may be formatted to include desired search result cluster attributes. The search result clusters are presented such that two or more associated search results form a single cluster of search results rather than being presented individually. In some embodiments, an option to view more search results with the same domain may be provided.

Backlighting systems for color display screens include clusters of LED devices of different colors that are configured to radiate the different colors in a light path that impinges on the color display screen, to provide backlighting on the color display screen. LED device controllers are provided, a respective one of which is configured to control operating parameters of a subset of the clusters of LED devices, a single cluster of LED devices and / or individual LED devices in the individual clusters. The LED device controllers may use a common data line.

A method and system for assigning unique words in an SDMA (spatial division multiple access) communication system is provided. A network management system logically arranges cell stations into clusters of stations, and monitors for a heavy traffic condition. Responsive to determining that a heavy traffic condition exists, the network management system may 1) redistribute unique words within a single cluster; 2) move one or more cell stations from a busy cluster to a less busy cluster; or 3) create a new cluster, and move cells from one or more busy cluster into the new cluster. In this way, the communication system continually adapts so that more unique words are made available at cell stations having heavier communication demands.
