A method for preventing or limiting the effects of Denial-of-Service attacks in a communication appliance having a packet-classification rule base which allows all legitimate packets to be forwarded to the communication appliance includes monitoring incoming packets to the communication appliance to determine whether conditions indicating a Denial-of-Service attack are present. If a Denial-of-Service attack is present, a rule base subset of the packet-classification rule base is selected from a plurality of rule base subsets based on a current one of a plurality of operating states of the communication appliance.

A contact center is provided that includes a plurality of agents for servicing incoming contacts and a target behavior identification module operable to (i) process a set of events to yield a corresponding measure; (ii) compare the measure to a plurality of rule sets, each of the rule sets corresponding to a different type of target behavior; and (iii) when the measure is defined by the a selected rule set, associate the measure with a type of target behavior corresponding to the selected rule set.

Methods and apparatus are provided for improving an admission control system using feedback control techniques based on a system performance measure. Generally, one or more performance metrics, such as system output error measurements, are fed back into the admission control system to adjust one or more system parameters and thereby improve the overall performance (e.g., reduce the error measurement). For admission control, one or more performance predictors are used to evaluate an expected quality of the call. The performance of the predictor is evaluated; and at least one of the one or more parameters is adapted based on the evaluation.

The application relates to the handling of content streams which are delivered to a telecommunications terminal during a call with an interactive voice response (IVR) system. When a content stream (whether video, audio, or both) is delivered to a telecommunications terminal during a call with an IVR system, a variety of events related to the content stream can occur, such as: completion of playback of the content stream; user control of the content stream (e.g., pause, stop, fast forward, etc.); a drop-off in quality of service (QoS) for the content stream (eg., due to network congestion, etc.); and so forth. In the prior art an event can be generated and caught in an IVR system script only when either (I) a caller provides input in response to a prompt from the IVR system script, or (ii) a prompt timeout occurs. It would however be advantageous if content stream-related events could be generated and caught by an IVR system script at any time during a call. This problem is solved in that the IVR system generates an asynchronous event (542) when there is a content stream-related occurrence during a call, and the asynchronous event is caught (552) by an appropriate event handler within the IVR system script. The event handler then spawns a separate thread (562) that handles the event accordingly and executes in parallel with the IVR system script (582), i.e the IVR system script continues handling the call while the thread executes.
摘要:
A method that seeks to provide a satisfactory quality of service for a stream of packets through a network. The illustrative embodiment of the present invention seeks to provide a satisfactory quality of service for a stream of packets by periodically or sporadically evaluating one or more alternative paths through the network and by sending the packets through a path with an acceptable quality of service. Normally, neither the source node nor any other node in a packet's path controls its route after it has left the node. In contrast, the illustrative embodiment of the present invention has the capability to affect the packet's path through the network by sending the packet to an intermediate or "ricochet" node in the network, which forwards the packet to the destination node. In effect, the source node can, if it deems appropriate, ricochet the packet off of the intermediate node rather than allowing the packet to take its normal direct path through the network.

An apparatus or endpoint device is disclosed for providing the capability to simultaneously manage multiple conference calls, move participants in the conference calls from one conference call to another and subdivide or join multiple conference calls together, and the like, wherein the apparatus or endpoint device provides a multi-conferencing capability that enables one or more teleconferencing participants to manage multiple teleconferences simultaneously. Each participant in the teleconference call manages their respective teleconference through their apparatus or endpoint device at their specific location by using it to adjust the teleconferencing topology, i.e., who should form what part of each specific teleconference call.

Methods and apparatus are disclosed for reducing wireless telecommunication costs for enterprises having a plurality of PBX-equipped sites, connected by either a public network ( e.g ., the PSTN, the Internet, etc .), a private network ( e.g ., leased lines, a virtual private network [VPN] over the internet, etc .), or some combination of public and private networks. In particular, the illustrative embodiments of the present invention attempt to reduce telecommunication costs by advantageously routing calls from an off-premises wireless terminal belonging to the enterprise via one or more of the enterprise's private branch exchanges. The present invention is especially advantageous in that it can reduce telecommunication costs for calls from an off-premises wireless terminal to any type of destination: another cell phone, a wireline terminal, a private branch exchange, etc .

The present invention provides a new network topology. More specifically, a peer-to-peer network is defined on a virtual private network. The peer-to-peer network comprises a set of specified users within a virtual private network that are allowed to communicate according to predetermined rules enforced by the peer-to-peer network itself. This affords secure communication between the specified users of the peer-to-peer network independent of the virtual private network.
摘要:
A method, apparatus and computer program product for transmitting broadcast/multicast data in a wireless network, is presented. The network includes either a plurality of multi-radio nodes, or a plurality of single-radio nodes, or a mix of multi-radio and single-radio nodes and the network further includes a control channel and at least one data channel. Transmission of the broadcast/multicast data occurs either on the control channel or on a data channel.
