Abstract: Methods and computer program products for using a front-end server to access content stored on one or more back-end servers. The front-end server receives requests for content from client systems. Back-end servers store the content, but to the client system, it appears as if the front-end server is the content's source. Upon receiving the request, the front-end server checks the validity of the request and examines a global catalog that dynamically maps client system requests to the back-end server or servers that store the requested content. In some circumstances, the content will be stored at a single back-end server and the front-end server directs the request to that server. Alternatively, a list of back-end servers storing the requested content may be generated. If so, the front-end then uses an authentication token as a key to a hash operation that is performed on the list and a single server that is capable of satisfying the request for content is identified.

Abstract: A multi-tiered server management architecture is employed including an application development tier, an application operations tier, and a cluster operations tier. In the application development tier, applications are developed for execution on one or more server computers. In the application operations tier, execution of the applications is managed and sub-boundaries within a cluster of servers can be established. In the cluster operations tier, operation of the server computers is managed without concern for what applications are executing on the one or more server computers and boundaries between clusters of servers can be established. The multi-tiered server management architecture can also be employed in co-location facilities where clusters of servers are leased to tenants, with the tenants implementing the application operations tier and the facility owner (or operator) implementing the cluster operations tier.

Abstract: A network identification system for use in a process control system creates and stores a unique network identification tag for input/output networks in the process control system. During the configuration process, each process controller is assigned a unique controller identification tag. In addition, each input/output device installed on each process controller is assigned a device identification tag. The network identification system creates a network identification tag for an input/output network by concatenating and combining the unique controller identification tag and the device identification tag. The network identification system may be configured to periodically transmit the network identification tag or to provide the network identification tag is response to a request for identification.

Abstract: In a digital telecommunications network having first and second addressing zones, a name and address server in the first addressing zone receiving from a first address of the first zone, assigned to a source machine, a request to provide an address in relation to the name of a destination machine situated in the second addressing zone, sends to a second address of the first zone a first packet containing at least the said name of destination machine, said second address of the first zone being associated in a static manner to a first address of the second zone, assigned to a management unit. The management unit sends to an interface a second packet destined for the name and address server comprising as origin address, a second address of the second zone assigned to the destination machine.

Abstract: A method for operating a telecommunications network is explained. A network element (16) at a network node of the telecommunications network is controlled by a control computer (36). The control computer (16) is maintained from a service computer (24). Allomorphy is taken into account in the development of application programs (102, 104) so that even a service computer (24) which is not developed can maintain the control computer (36). Making allowance for allomorphy results in little additional expenditure because an interface program (100) is used in which essential processing steps are carried out for all the application programs (102, 104), said processing steps ensuring that allomorphy is taken into consideration.

The method includes generating an observed mapping of the nodes in the interconnection fabric showing a location of a first node relative to an x-axis of the fabric and relative to a y-axis of the fabric, comparing the observed mapping of the nodes to a set of expected mappings, and identifying the expected mapping which is most similar to the observed mapping.

Abstract: A method for efficiently sending notifications over a network. A client system requests to be notified when an event occurs. A server system receives the requests and monitors for the occurrence of the event. When the event occurs a single packet using a connectionless protocol (such as User Datagram Protocol) is sent to the client to notify the client of the occurrence of the event. Using a connectionless protocol to send notification reduces the overall amount of data on the network and thus reduces network congestion and the processing capacity of the server and client. When the client system receives notification an attempt to establish a connection using as connection-oriented protocol is executed. Additional data associated with the occurrence of the event is transferred over the connection. The server may repeatedly send notification using a connectionless protocol until a connection using a connection-oriented protocol is established.

Abstract: A method of provisioning a connection across a SONET/SDU network formed from multiple sub-networks comprises: determining a model of the entire network, the model indicating the connections between all sub-networks, and representing each sub-network as a single unit; calculating a route between the sub-networks containing the first and second nodes using the model; passing the signals along the determined route, and determining the route between nodes within each sub-network locally within the respective sub-network. This method enables a simplified model of the network to be stored in each node of the network, so that a route calculation can take place at the sending node. The specific route through the network is determined as the signal passes through the network, as the specific path through individual sub-networks is determined locally.
