A proactive worm containment (PWC) solution for enterprises uses a sustained faster-than-normal outgoing connection rate to determine if a host is infected. Two novel white detection techniques are used to reduce false positives, including a vulnerability time window lemma to avoid false initial containment, and a relaxation analysis to uncontain (or unblock) those mistakenly contained (or blocked) hosts, if there are any. The system integrates seamlessly with existing signature-based or filter-based worm scan filtering solutions. Nevertheless, the invention is signature free and does not rely on worm signatures. Nor is it protocol specific, as the approach performs containment consistently over a large range of worm scan rates. It is not sensitive to worm scan rate and, being a network-level approach deployed on a host, the system requires no changes to the host's OS, applications, or hardware.

Routing table update messages that include both network-level and link-level addresses of nodes of a computer network are exchanged among the nodes of the computer network. Further, a routing table maintained by a first one of the nodes of the computer network may be updated in response to receiving one or more of the update messages. The routing table is preferably updated by selecting a next node to a destination node of the computer network only if every intermediate node in a path from the next node to the destination node satisfies a set of nodal conditions required by the first node for its path to the destination node and the next node offers the shortest distance to the destination node and to every intermediate node along the path from the next node to the destination node. The shortest distance to the destination node may be determined according to one or more link-state and / or node-state metrics regarding communication links and nodes along the path to the destination node. Also, the nodal characteristics of the nodes of the computer system may be exchanged between neighbor nodes, prior to updating the routing table. Preferred paths to one or more destination nodes may be computed according to these nodal characteristics, for example using a Dijkstra shortest-path algorithm.

Disclosed herein is a two-level, network-based application control (NBAC) architecture for monitoring services provided via a packet-based network. The NBAC architecture includes a Network Trigger System provided at a network level to analyze data flows relating to services to be monitored to detect occurrence of configurable events, and to generate and send event reports; and a Usage Status Engine provided at a control level to configure the Network Trigger System to detect occurrence of events of interest, and to receive and process the event reports from the Network Trigger System to monitor the services.

The present invention provides a method and system for reducing power consumption in a Wireless Sensor Network. The Wireless Sensor Network includes a plurality of nodes forming a tree structure. The nodes send data towards a root node via parent nodes. The nodes adaptively control the wake-up schedules of radio transceivers based on the network level information of the nodes, thereby reducing the active wake-up interval of the radio transceivers and in turn decreasing the overall power consumption of the Wireless Sensor Network.

To address the problem of providing network-based security to mitigate and detect cheating in peer-to-peer (P2P) gaming architecture, an architecture suite called architectures with coordinator obfuscation for resilient P2P gaming networks (ACORN) is presented that uses a combination of low overhead, per-packet access authentication, moving-coordinator and cheat detection mechanisms to effectively mitigate security threats.

A computer program product is configured to control a modular transmission system having a control processor and at least N power amplifier modules, each having a controller submodule, wherein the system receives an input signal which may be a single carrier or multiple carriers. The signal is passed to a one-by-N divider which divides the signal N ways. Each of the N divided signals are independently amplified by the power amplifier (PA) modules "slices" (i.e., PA modules) that includes an RF amplifier module, a microcontroller module, and a power supply module, all of which are tightly coupled via a plurality of signal, power, control, and status connections. Each the PA slices amplifies its respective input signal and outputs a respective radio frequency output signal at a predetermined power level as controlled by the microcontrol module, the driver, and the system controller, or a network manager via a system input / output interface. The output coupler provides power coupling and status monitoring via feedback lines to support control at a module-level, a system-level, and a network-level.

A network operating system NOS for an agile optical network with a plurality of mesh interconnected switching nodes, manages the network using an object-oriented network information model. The model is common to all applications requiring the data stored in the network managed information base. The core model can be expanded for serving specific application areas. The NOS is organized in layers, at the optical module level, connection level and network level. A distributed topology server DTS organizes the physical, logical and topological data defining all network entities as managed objects MO and topology objects TO for constructing a complete network view. The network information model associates a network element NE information model, specified by managed objects MO and a topological information model, specified by topology objects TO. The MOs are abstract specific NE data that define network implementation details and do not include any topological data, while the TOs abstract specific topological data for defining a trail established within the network, and do not include any NE data. The models are associated in a minimal number of points to construct the model of a trial in response to a connection request.

A Personal Digital Key Digital Content Security System (PDK-DCSS) is used to protect computers from unauthorized use and protect the digital content stored on computers from being wrongfully accessed, copied, and / or distributed. The basic components of the PDK-DCSS are (1) a standard hard drive device, with the addition of a PDK Receiver / Decoder Circuit (PDK-RDC) optionally integrated into the hard drive's controller, and (2) a PDK-Key associated with the PDK-RDC. The PDK-Key and RDC technology is utilized to provide two categories of protection: (1) hard drive access control for providing Drive-Level and Sector-Level protection and (2) operating system-level independent file protection for providing File-Level and Network-Level protection.

An automatic service discovery approach allows a network management system to discover service managed objects from the network, eliminating the need for a user or other management application to provide such information. As a result, a network management system can automatically perform network-level or services level discovery of objects and services for which network components have no understanding. Embodiments are applicable, for example, in the context of management of packet voice (VoIP, VoATM) and metro Ethernet (TLS service) domains, as well as other domains.

A system for estimating call waiting time for a call in a queue takes into account multiple queues wherein agents are shared between queues, abandoned call history, and virtual and priority queues. The system in a preferred embodiment is a computer-telephony integration (CTI) software application adapted to execute on a CTI processor, which may be coupled to switching equipment at network level in a connection-oriented, switched telephony (COST) network or to a switch at call-center level, or both.
