Abstract: Methods related to communication between and within nodes in a high performance computing system are presented. Processing time for message exchange between a processing unit and a network controller interface in a node is reduced. Resources required to manage application state in the network interface controller are minimized. In the network interface controller, multiple contexts are multiplexed into one physical Direct Memory Access engine. Virtual to physical address translation in the network interface controller is accelerated by using a plurality of independent caches, with each level of the page table hierarchy cached in an independent cache. A memory management scheme for data structures distributed between the processing unit and the network controller interface is provided. The state required to implement end-to-end reliability is reduced by limiting the transmit sequence number space to the currently in-flight messages.

Abstract: Technology for mitigating traffic congestion is disclosed. A master evolved node B (MeNB) can identify service data unit (SDU) packets that are dropped in a retransmission buffer of a packet data convergence protocol (PDCP) layer of the MeNB. The MeNB can create a list of packet data unit (PDU) packets that are dropped at the PDCP layer of the MeNB, wherein the PDU packets that are dropped are associated with the SDU packets. The MeNB can send the list of dropped PDU packets, from the PDCP layer of the MeNB to the PDCP layer of a user equipment (UE), to enable the UE to distinguish between delayed PDU packets and the dropped PDU packets.

Abstract: In order to minimize traffic on a Zigbee network, a gateway of the Zigbee network represents end devices in communications with peripheral networks. The gateway receives messages, such as status request messages, from the peripheral network intended for an end device on the Zigbee network. The Zigbee network generates a response message by retrieving stored data for the end device instead of communicating the received message to the end device.

Abstract: To realize quick adaptation to a communication link between a transmitter and a receiver by using two different frequency carriers. A receiver detects a preamble from a transmission bit string. When determining that a total sum of the number of modified bits exceeds a certain threshold in a range of a payload following the preamble (when detecting that a reception state of a communication link has been degraded), the receiver issues, to a transmitter, a request for changing a transmission parameter (four parameters may be used for enhancement/lowering) for the transmission bit string by using a communication link, which is a relatively-low-frequency carrier. On the other hand, the transmitter receives the request for change, and executes the request for changing the transmission parameter for the transmission bit string while maintaining transmission of a payload in the transmission bit string.
