Abstract: Virtual networks may be launched in a provider network with an initial IP address space (e.g., an IPv4 CIDR block). Methods are described that allow additional IP address spaces to be added to a virtual network. A new IP address space for a virtual network may be specified via an API. The specified space may be checked to insure that it does not overlap with IP spaces that are associated with the virtual network. If there are no overlaps, the space is added to the network, for example by adding the space to the network's route tables.

Abstract: A Voice-over-IP (VOIP) system includes a plurality of multi control units (MCUs), in which a first MCU hosts a VOIP session. A method for recommending an MCU to host the VOIP session includes receiving MCU status associated with performance of each of the first MCU and a second MCU included in the VOIP system. The method further includes determining, based on the first and the second MCU status, that hosting the VOIP session on the second MCU can improve a VOIP system metric. According to the method, a recommendation is communicated to transfer hosting the VOIP session to the second MCU.

Abstract: A conference call management method, system, and computer program product include inferring an Internet Protocol (IP) address of a new user requesting to join a call including at least one other user, inferring a codec to stream an emulated network pattern for the call if the new user were to join the call, measuring a call quality perceived by the at least one other user in the call while the emulated codec is run on the call, and measuring an impact on the call quality in a case that the new user joins the call based on the perceived call quality and the network pattern.

Abstract: A Voice-over-IP (VOIP) system includes a plurality of multi-control units (MCUs). A first MCU in the VOIP system hosts a first VOIP session that joins a plurality of conference devices. Based on an impact metric being acceptable, and an alternate MCU accepting to host the VOIP session, the system joins the plurality of conference devices to a replacement VOIP session hosted on the alternate MCU.

Abstract: A computer system for improving the presentation of social media data from multiple social network feeds is provided. The computer system may include aggregating social media content received from the multiple social network feeds. The computer system may also include generating filtered data by eliminating repetitive data from among the received aggregated social media content. The computer system may further include analyzing the filtered data for determining at least one data category and presenting a digest of social media content based on the determined at least one data category.

Abstract: A method, system, and/or computer program product improve Voice over Internet Protocol (VoIP) call quality during a VoIP session. A VoIP session is established between an initial focus VoIP node and multiple slave VoIP nodes, where the initial focus VoIP node uses a first type of codec for the VoIP session. A user focus code score (UFCS) describes a VoIP call quality for each of the nodes based on predetermined network conditions related to use of a certain type of codec and nodal hardware specifications. The UFCSs are ranked to identify a highest-ranked VoIP node. The highest-ranked VoIP node is reclassified as a new focus VoIP node for the VoIP session, and the initial focus VoIP node is reclassified as a slave VoIP node. Thereafter, there is a simultaneous switching of 1) the focus and 2) the type of codec used in the VoIP session.

Abstract: A method of optimising a digital test signal for testing an analogue or mixed-signal circuit comprising determining a measure, for example a figure of merit, that is indicative of differences between the output of a fault free and the output of a known faulty circuit in response to an applied digital input signal. The digital input signal is then varied and another figure of merit is calculated for the fault free and the known faulty circuit for the new input signal. This is repeated a number of times, the digital input signal being varied each time. An optimum test signal is selected based on the determined figures of merit.
