Abstract: The practice and need for active network measurement is well established, however, current tools are not well suited to this task, mostly because the protocols which they employ have not been designed for measurement of the modern Internet. The IP Measurement Protocol (IPMP) is based on packet-probes, and is designed to allow routers to participate in measurements by the insertion of path information as the probe passes between a pair of hosts.

Abstract: The practice and need for active network measurement is well established, however, current tools are not well suited to this task, mostly because the protocols which they employ have not been designed for measurement of the modem Internet. The IP Measurement Protocol (IPMP) is based on packet-probes, and is designed to allow routers to participate in measurements by the insertion of path information as the probe passes between a pair of hosts.

Abstract: A communication interface between an order generating program that generates orders and an order processing program that processes orders is managed. At least one metric that is based on orders passing from the order generating program to the order processing program is monitored. The communication interface between the order generating program and the order processing program is determined to have failed based on the monitored metric. The communication interface is then restarted based on when it has been determined to have failed.

Abstract: A telecommunications system and method for increasing communications bandwidth for an Internet Service Provider (“ISP”) to accommodate temporary fluctuations in demand. The present invention utilizes an Advanced Intelligent Network (“AIN”) to re-direct calls from a subscriber to an ISP from the ISP's modem pools to a shared modem pool operated by a telephone service provider (“telco”) when the ISP needs additional bandwidth. The shared modem pool is controlled by an access server and a remote authentication dial-in user service server managed by the telco. The telco servers identify the identified ISP to receive the call by looking at the original number dialed by the caller. The telco servers then communicate with the proper ISP which determines whether or not the caller is a valid subscriber of the ISP.

Abstract: A method for disrupting unauthorized communications between at least two communication devices is provided. The method comprises using an address resolution protocol (ARP) to redirect transfer of data that occurs using unauthorized wireless communication between a first wireless device and a second wireless device. In a preferred embodiment, the method maintains a layer two wireless link while the data are being redirected.

Abstract: A recovery method for use in a connection-oriented network having nodes interconnected by links for establishing connections within the network, the method described enables the recovery of connections in the network in the event of a failure. The recovery method includes the following steps: (a) assigning connection re-routing priority to the connections in the network based on configured polices in response to the failure; and (b) creating release message bundles based on the assigned connection re-routing priority for use by the nodes in the network to recover connections. More specifically, a failure (e.g., link failure) could affect hundreds or thousands of connections passing through a node. To recover these connections, the node determines which connections should be recovered first and which connections can wait (or may never be recovered). The recovery method determines the priorities of re-routing connections after failure.

Abstract: The system and method of the present invention enable the user to build and/or use an interactive visual instrument panel for monitoring and/or managing one or more target systems locally or remotely in real-time, with the instrument panel being configured based on the user-defined requirements and based on the attributes of the target system(s) being monitored and/or managed. In one embodiment of the present invention a novel data handling system is provided for ensuring that the target system is able to continuously transmit real-time data without any data loss and without interrupting its operation.

Abstract: A computer assembly for example for use as a network server comprises housing a host processor located within the housing and, a service processor also located within the housing for providing system management functions within the computer assembly. The housing includes a display that is located thereon for displaying the status of components of the assembly obtained from the service processor, and one or more manual switches located on the housing for enabling a user to vary information displayed by the display and/or to alter the status of the equipment. The computer assembly may include a console interface that communicates with the service processor to enable the system management functions of the assembly to be monitored and/or the status thereof to be modified from a remote console connected thereto in addition to or instead of by the display and switches.

Abstract: An improvement in the compilation of classification tables from across control lists increases the efficiency of memory utilization by fragments in the lower level tables and using the classification ID's from a pair of higher-level tables as pointers to the fragments and as indicators of the depth of the entries in the fragments. A further improvement makes use of aggregate bit vectors, thereby simplifying construction of the lower-level tables. The bit-vector sections preferably coincide with the cache lines of the processing, thereby maximizing the speed with which the relevant bits in the bit vector can be identified from the aggregate bit vectors.

Abstract: An invention is provided for data bit align. The invention includes a multiplexer that receives a data sample word as data input and also receives a clock sample word as select input. The multiplexer selects a data bit from the data sample word based on the clock sample word. Generally, the multiplexer can select the data bit from the data sample word corresponding to a position of the clock edge in the clock sample word. The invention also includes an output register, which is coupled to the multiplexer. The output register stores the selected data bit from the multiplexer and provides the selected data bit to remaining system components.

Abstract: The invention provides a system and a method for splicing network connections. In one embodiment, the method maintains first and second connections with first and second network nodes respectively; and selectively splices the first and second nodes based on application header information associated with inbound data packets received from the first node in reply to a request from the second node.

Abstract: Systems and methods are provided wherein call-blocking probability of a telecommunications system is calculated based on consideration of over flow paths and alternate routes. Once the routes and overflow pathways are identified, the total number of call attempts and calls failed, due to congestion, is determined from statistical route data. Dividing the number of failed calls due to congestion by the number of attempted calls results in the blocking proportion for each route that is used by the methods disclosed herein to calculate the probability of blocking for that route.
