Abstract: A method for sending a multi-rate multi-receiver message containing a multi-receiver multi-response aggregate. The multi-rate multi-receiver aggregate is transmitted until a multi-receiver multi-response aggregate embedded within the multi-rate multi-receiver aggregate is encountered. Transmission of the multi-rate multi-receiver aggregate is suspended for a predetermined time period. After the expiration of the predetermined time period, transmission of the multi-rate multi-receiver aggregate resumes.

Abstract: A method of facilitating a telephonic response to an electronic message is described. The method includes determining at least one telephone number from a received electronic message, and assigning the determined telephone number dynamically to a button on the telephone to provide a speed dial button on the telephone. Determining the telephone number may include comparing an electronic mail address in an address field of the electronic message with a telephone directory to determine a telephone number associated with the address. If the electronic message is a text or a voice message, determining the telephone number may include parsing a body of the message to determine a telephone number, if present, which has been included into the body of the text message.

Abstract: In one embodiment, a method includes identifying a plurality of network elements for reinitiation, wherein the network elements are operative to manage at least one child element; selecting a first network element from the plurality of network elements, transmitting a disable message to the first network element; determining whether the at least one child element has migrated to one or more alternate network elements; and conditionally transmitting a reinitiation message to the first network element.

Abstract: In an example embodiment, a system for providing a Virtual Local Area Network (VLAN) by use of encryption states or encryption keys for identifying a VLAN. A table of data including a VLAN and an associated encryption state or key is provided for assignment of encryption states or keys, for devices in a wireless local area network.

Abstract: Particular embodiments provide for attenuating one or more microphone signals in a teleconferencing system upon detecting a non-audible signal. A far end voice signal is received from a sound source. A non-audible signal is added to the far end voice signal to create a composite signal, which is provided to one or more speakers. The speakers output the composite signal and the non-audible signal are detected in the composite signal after the composite signal is received at one or more microphones. The non-audible signal allows an attenuator to attenuate a microphone signal including the composite signal from a particular microphone in response to the detected non-audible signal to reduce far end echo.

Abstract: Methods and apparatus are provided for improving the configuration, management, and distribution of quality of service information in a fibre channel fabric using zoning mechanisms. Configuration of Quality of Service (QoS) information is made easy by using zones as a classifier for flows. QoS information is included in zone objects, thereby using the existing zone distribution mechanism to distribute QoS information. Devices not part of any zones are placed automatically in the default zone with a default QoS priority level. QoS information for a particular packet is available as soon as the zoning information is obtained.

Abstract: Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with a shift register with a dynamic entry point, which may particularly useful for aligning skewed data. The dynamic entry shift register typically includes a series of storage elements, with multiplexers distributed between the storage elements. Each of the multiplexers is configured to select between: (a) the output signal of a previous storage element, and (b) the input signal. A control is configured to configure the multiplexers for a data signal applied as the input signal to induce an appropriate delay of the data signal as the output signal. The dynamic entry shift register can be scaled to accommodate a longer delay while still using only 2:1 multiplexers between stages in the dynamic entry shift register(s).

Abstract: A method for providing fail-over capability in a local branch of a call center includes determining, by a local device, which of a plurality of phones are call center phones. The determination is based on a predetermined rule set. In an alternative embodiment, the method may also include determining, by the local device, which of the plurality of call center phones are available for receiving calls. This may include determining whether a “do not disturb” function of each respective call center phone is invoked, and in response, determining whether the call center phone is available. In addition, this method may involve placing, by the local device, each call center phone into a “do not disturb” mode if the call center phone does not answer a call sent to the call center phone.

Abstract: In one embodiment, a method includes receiving a multicast join message at a node having a plurality of interfaces, identifying the interface at which the join message was received, and selecting one or more of the interfaces to transmit the join message based on whether the join message was received on a ring interface. If the join message was received on one of the ring interfaces, the join message is transmitted on another of the interfaces. If the join message was not received on one of the ring interfaces, the join message is transmitted on both of the ring interfaces. The method further includes receiving multicast data and transmitting the multicast data on the interface at which the join message was received.

Abstract: An apparatus for limiting Virtual Private Network (VPNv4) prefixes per VPN in an inter-autonomous system environment are presented. A limit on the number of VPNv4 routes per VPN for a Route Distributor (RD) or a group of RDs associated with a VPN is defined, at an Autonomous System Border Router (ASBR). When the number of received routes at the ASBR exceeds the limit, then a soft notification is sent to a neighboring ASBR and routes exceeding the limit are discarded at the ASBR.

Abstract: A technique triggers optimization of a traffic engineering (TE) label switched path (LSP) that spans multiple domains of a computer network from a head-end node of a local domain to a tail-end node of a remote domain. The technique is based on the detection of an event in the remote domain (“event domain”) that could create a more optimal TE-LSP, such as, e.g., restoration of a network element or increased available bandwidth. Specifically, a path computation element (PCE) in the event domain learns of the event and notifies other PCEs of the event through an event notification. These PCEs then flood an event notification to label switched routers (LSRs) in their respective domain. Upon receiving the notification, if an LSR has one or more TE-LSPs (or pending TE-LSPs), it responds to the PCE with an optimization request for the TE-LSPs. The PCE determines whether a particular TE-LSP may benefit from optimization based on the event domain (i.e.

Abstract: A method for facilitating a data session in a communications environment is provided that includes initiating, by a first endpoint, a call that is intended for a second endpoint. The method also includes invoking, by the first endpoint, an eCamp-On™ feature in response to the second endpoint being unavailable. The eCamp-On™ feature initiates a new call between the first and second endpoints once the second endpoint is available. Presence data associated with the first endpoint may be leveraged in order to make the new call.

Abstract: Methods and devices for querying any-service-any-port policy systems. A method for a network device to route calls using policy considerations receives a call request associated with a call and queries a policy system to determine if the network can accept the call. A message is then generated that includes a response to the request.

Abstract: In an example embodiment, there is described herein a “Wireless Route Aggregation Protocol” (WRAP) that is used to aggregate multiple wireless links into a WRAP “route bundle” that functions as a single logical LAN bridge link. WRAP link aggregation can be used for example to increase the bandwidth and robustness of the wireless path between two wired Ethernet LANs.

Abstract: A method of distributing labels in a label distribution protocol multicast network having a root node and at least one leaf node comprises the steps, performed at a receiving node, of receiving a label and path vector from a distributing node, carrying out loop or convergence detection from the received path vector and, if convergence or no loop is detected, sending a receiving node label and path vector to its nexthop node in the network.

Abstract: A method for implementing a virtual line channel in a packet switched network includes reserving a virtual line channel associated with a first station and establishing a communication session between the first station and a second station over the virtual line channel. The reservation of the virtual line channel is maintained while the communication session is active. The communication session may be transferred to a different channel associated with a third station. The reservation of the virtual line channel is maintained while the communication session is active despite the transfer of the communication session. When the communication session has terminated, the reservation of the virtual line channel is released.

Abstract: A system for inter-enterprise telephony communications includes a central brokerage device that can receive a packet encoding a dialed telephone identifier generated by a first telephony device located in the first enterprise network, where the dialed telephone identifier is associated with a second telephony device located in a second enterprise network. The central brokerage device can also identify a network address of the second enterprise network using connectivity information if the dialed telephone identifier matches resolution information. The system also includes the first enterprise network, which can establish an encrypted communication link with the second enterprise network through a packet-based network using the identified network address if the dialed telephone identifier matches the resolution information.
