Abstract: A communications access point may provide access to a wireless communications network to a user device located at a first location. The communications access point may determine that the user device is moving from the first location to a second location where access to the wireless network is limited or not available. In response to the determination, the communications access point may provide access to the wireless network at the second location by extending a coverage area of the wireless network.

Abstract: The InfiniBand transport protocol supports the concept of a SRQ (shared receive queue) by which multiple QPs (queue pairs) can share the same receive queue resources. According to the InfiniBand Specification, when a SRQ is enabled, flow control needs to be disabled. The lack of flow control mechanism results in there being no fairness guarantees across multiple requesters. Fairness across requesters can be obtained by implementing a SRQ configured to receive request messages from requesters initiating transactions that consume WQEs (work queue elements) of the SRQ, monitoring consumption of the WQEs by the requesters, determining that a requester has a WQE consumption exceeding a policing threshold, and in response to determining that the WQE consumption of the requester exceeds the policing threshold, sending a response message to the requester that results in reducing the WQE consumption of the requester.

Abstract: A software-defined network (SDN) rule modification counter system provides counters that track all changes and edits to rules at SDN controllers and SDN switches on an SDN. The system compares counters at the SDN controller and SDN switch to determine if they match. If the counters do not match, a change has been made to the rules. With the addition of rule edit statistics the SDN controller will now have visibility that a rule modification was performed. The SDN controller then verifies that the state of the device is the same as its expected state as a secondary integrity check. Based on the rule modification notification, changes to a central rules table at the SDN controller and changes to rule settings at the SDN switch are made according to pre-programmed logic.

Abstract: In some implementations, a provider edge device associated with a link aggregation group (LAG) may maintain, according to a link aggregation control protocol (LACP), a set of links that connect the PE device to a consumer edge device. The provider edge device may determine that the provider edge device and another provider edge device associated with the LAG are not receiving link aggregation control protocol data units (LACPDUs) from the consumer edge device. The provider edge device may cause the set of links to have a maintain LAG status, which causes the provider edge device to keep up the set of links and to cease maintaining the set of links according to the LACP. The provider edge device may route, based on causing the set of links to have the maintain LAG status, one or more packets to or from the consumer edge device via the set of links.

Abstract: A wireless communication system non-collaborative, multiple input, multiple output (MIMO) space division multiple access (SDMA) system determines subscriber station combining and weighting vectors that yield a high average signal-to-interference plus noise ratio (SINR). Each subscriber station independently transmits information to a base station that allows the base station to determine a weight vector wi for each subscriber station using the determined combining vector of the subscriber station. The ith combining vector corresponds to a right singular vector corresponding to a maximum singular value of a channel matrix between a base station and the ith subscriber station. Each subscriber station transmits signals using a weight vector vi, which corresponds to a left singular vector corresponding to a maximum singular value of a channel matrix between the ith subscriber station and the base station. The base station uses the weight vector wi to determine the signal transmitted by the ith subscriber station.

Abstract: An information processing apparatus includes a first memory, a second memory, and a control circuit. The first memory stores a first table where entries, which indicate forwarding methods for packets, are stored at positions corresponding to hash values calculated from header information of the packets. The second memory stores a second table that is larger than the first table. The control circuit detects, when the first table is updated, a conflict state where there is conflict between storage positions of different entries in the first table. The control circuit moves entries stored in the first table to the second table in response to the detecting of the conflict state. The control circuit detects resolution of the conflict state when the second table is updated. In response to the detecting of the resolution, the control circuit moves the entries stored in the second table to the first table.
