Abstract: A method is disclosed of optimizing calls set up in a private telecommunication network including two subnetworks using the QSIG protocol and the Session Initialization Protocol, respectively, when a first terminal belonging to the subnetwork using the SIP requests the setting up of a call with a server associated with a first switch belonging to the subnetwork using the QSIG protocol and the call must be transferred to a second terminal belonging to the subnetwork using the SIP. The two subnetworks are connected by a QSIG/SIP gateway associated with a second switch of the subnetwork using the QSIG protocol. The method conventionally sets up a first call between the first terminal and the first switch and a second call between the first switch and the second terminal and then joins the two calls in the first switch so that the first and second terminals communicate via the gateway, the first switch, and the second switch.

Abstract: The present invention provides a system and method of calculating a service disruption in a communication network comprising network elements, including nodes connected via links and at least one originating node. Each node is able to detect a failure in an adjacent network element. Upon detection of a failure, a first timestamp is generated. The detecting node generates a release signal which is transmitted, together with the first timestamp, to an originating node which releases the affected connection. The originating node establishes a new connection and initiates a new call. Upon establishing a new connection, a node affected by the failure, which forms a part of the new connection, records a second timestamp. The second timestamp is chosen to reflect, as closely as possible, the actual time of restoration of service in the network. Service disruption is measured as a difference between the first and second timestamps.

Abstract: Customer e-mail service requests are allocated to plural working groups for response through virtual queues that store unanswered e-mail and meter the unanswered e-mail to working queues that make the e-mails available to associated working groups. The working queues are replenished from the virtual queues to maintain above a minimum and up to a maximum number of e-mails. The virtual queues are manipulated to control e-mail flow rates by allocating e-mails to virtual queues based on desired factors and by moving e-mail between virtual queues as needed to manage working groups. The virtual queues allow tracking of e-mail response metrics and monitoring of working group performance and timeliness.

Abstract: A method, system, and product in a data processing system are disclosed for providing centralized management of an INFINIBAND distributed system-area network that includes multiple end nodes. A manager application is established in one of the end nodes. An agent application is established in one or more end nodes. Each agent application is independent from the manager application. The manager application maintains a current list of active agent applications and uses the list to manage the agent applications in the end nodes.

Abstract: A client issues a first electronic request to access a service at a server. The server receives the request and identifies a type of challenge form among a number of different types of challenges (e.g., represented by a number of different XML schemas). The server issues a challenge, in accordance with the identified type of challenge, to the client. The challenge can include state information that indicates to the server when an appropriate response to the challenge is received. The client receives the challenge and formulates a response (including the state information) to the challenge in accordance with the identified type of challenge. The client issues a second electronic request, which includes the formulated response. The server receives the response and determines, based on the response, if the second electronic request is to be processed.

Abstract: A rental company system 100 comprises a branch master table 124 for unitarily registering and managing the content of inquiries made at each branch office. In response to an operation performed by a branch operator, a branch terminal 112 in each branch office displays a “reception registration and modification” screen 907 and receives input of a plurality of types of inquiry content information. The branch terminal 112 registers the inputted inquiry content information in the branch master table 124 via an internal network 110. In response to an operation performed by a branch operator, the branch terminal 112 displays an “inquiry content information transfer” screen 980 and transfers the inquiry content information inputted into the “reception registration and modification” screen 907 to a portable telephone 801 of a transmission receiving party inputted into the aforementioned screen 980.

Abstract: An intelligent computer switch is described. The intelligent computer switch has an automatic detection capacity to control a plurality of computers with at least one keyboard, at least one mouse and at least one monitor. The intelligent computer switch comprises an input port, a control device, an output port, and a plurality of computer connection ports. The input port receives input commands and data, and the output port sends output commands and data. While a series connection cable connected to the input port, the intelligent computer switch is determined to be a slave. While the series connection cable is not connected to the series connection cable, the intelligent computer switch is determined to be a master. The intelligent computer switch further comprises an on-screen display function and an authority-setting function with at least 4 sets of passwords for different users.

Abstract: A Denial of Service (DoS) mitigation scheme increases the ability of a call processing server to fend off DoS attacks. The DoS mitigation scheme identifies a probability for dropping or denying a call request according to the current load on the call processing server. The probability is then weighted according to certain characteristics of the call request. For example, a call request from a previously authenticated source may be given a different weight than a request from an unauthenticated source. The weighted probability is then compared with a randomly generated number and the call request accepted or rejected according to the comparison.

Abstract: A method of performing automatic Trivial File Transfer Protocol (TFTP) firmware download, includes: obtaining, by either a network-connected device (i.e., DHCP) or user (i.e., command file), a configuration file, where the configuration file includes an Internet Protocol (IP) address of a target device and a file name of a target file in the target device; retrieving a software image from the target file; determining if there is a match between the software image from the target file and another software image currently running on the device; and downloading to the network-connected device the software image from the target file if the software image is compatible and different from the software image currently in the device.

Abstract: Peer-to-peer endpoint devices discover a localized IP address realm that minimizes the traversal of the Network Address Translators. Each endpoint device sends a query from its corresponding local address realm to its corresponding destination endpoint device using the corresponding available address for the destination endpoint device. The available address has a value outside the address realm of the endpoint device sending the query. The query also specifies a unique identifier that is identifiable solely by the endpoint device. The destination endpoint device receives the query, having traversed one or more NATs and at least two address realms, and sends a response that specifies the unique identifier for the query source, a unique identifier for the destination endpoint device, and multiple alias addresses for reaching the destination endpoint device. The query source selects one of the alias addresses that is determined reachable by the query source.

Abstract: A system and method of predicting network data traffic includes coupling a first group of clients to a current server that results in a current CPU utilization of the current server. A second group of clients are coupled to the current server. A load multiple is determined and the current CPU utilization is compared to a predicted CPU utilization. A server requirement is increased if the current CPU utilization is greater than or equal to the predicted CPU utilization.
