摘要： A method for bypassing congestion points in a network includes sampling queues of a plurality of switches in the network. When packet congestion is detected at a congestion point of a first switch, the packet flow contributing to the packet congestion is identified. A congestion notification message indicating the identified packet flow is then propagated to upstream switches, which are upstream from the first switch in the network. The congestion notification message is then snooped by the upstream switches. Virtual queues within the upstream switches are associated with the identified packet flow to hold packets associated with the identified packet flow. The packets associated with the identified packet flow are then re-routed to bypass the packet congestion in the first switch.

摘要： A system is provided for enabling a non-speculative pre-fetch operation for processing instructions to be performed in the background ahead of immediate packet processing by a packet processor. The system comprises a packet-management unit for accepting data packets and en-queuing them for processing, a processor unit for processing the data packets, a processor core memory for holding context registers and functional units for processing, a memory for holding a plurality of instruction threads and a software-configurable hardware table for relating queues to pointers to beginnings of instruction threads. The packet-management unit selects an available context in the processor core for processing of a data packet, consults the table, and communicates the pointer to the processor, enabling the processor to perform the non-speculative pre-fetch for instructions.

摘要： A multi-channel telephonic communications system, (PBXA-PBXD), where voice, data, facsimile information is packetized and switched to the desired destination based upon a call number embedded in each packet which is based upon the digits dialed at the source. Aswitching architecture (44) is used to minimize the trunk line resource needed and to simplify system configuration and maintenance. Connection between the source and the desired destination are allowed if there is sufficient bandwidth to support the connection. Flow control is also provided, which dynamically varies the bandwidth provided. Flow control is also provided, which dynamically varies the bandwidth used by voice packets to adjust to changing traffic levels. Voice bandwidth is reduced when needed by the traffic volume, and voice bandwidth is increased when possible to improve voice quality.

摘要： A system for controlling the flow of data cells through a packet switch combines both input and output buffers in a feedback loop. The fullness level of output buffers is continuously monitored and reported to an access device on the input side of the switch. The access device includes input buffers and a throttling device to stop the flow of data cells, and hold them in the input buffers, when the fullness level of the output buffers exceeds a predetermined level. A status message of output buffers fullness is compared to an access message indicating which output buffers are addressed by cells in the input buffers, and only those cells addressed to overfull output buffers are stopped by the throttling device.

摘要： A communication method and packet switching system in which packets comprising physical addresses and voice/data information are communicated through the system by packet switching networks (116) which are interconnected by high-speed digital trunks (118) with each of the latter being directly terminated on both ends by trunk controllers (131, 140). Customer terminals (100) are connected to the switching system by access line controllers (112a) which insert the physical addresses into the packets. The line controllers attach to concentrators (112) which are interconnected to the switching networks via high-speed digital trunks (117). During initial call setup of a particular call, the physical addresses are obtained and stored in the line controllers by the transmission of a call setup packet and call reply packet between the originating and destination line controllers. Each processor (111) inserts into the call setup packet the necessary addressing information to route packets through the associated network. Each network comprises stages of switching nodes which are responsive to the physical addresses in a packet to communicate this packet to a designated subsequent node. The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols.

摘要： When a user of a mobile device attempts to use an application having high data demands, the mobile device queries its cellular data provider to determine currently available data transfer rates, based on the geographic location of the mobile device and the demands on the cellular base station from which the mobile device is being served. If the base station is experiencing data congestion, which is likely to result in a less than optimum user experience, the mobile device displays a warning to the user suggesting that the user postpone usage of the application or try using the application in a different geographic location that is experiencing less congestion.

摘要： For managing a traffic overload in a software defined network (70) having an SDN controller (10), when an indication of a traffic overload is received (200), there are steps of identifying (208) traffic flows which contribute to this, identifying (210) nodes (20, 21, 22) of the network controllable by the SDN controller and located along a path of the identified traffic flows before the location of the traffic overload. The SDN controller is used to control (220) the identified nodes to control the identified traffic flows to reduce the traffic overload. By using the SDN controller to control the reduction compared to diverting suspicious traffic flows to a separate external security server, the extra network resources used for carrying the diverted traffic flows are not needed, the separate security server is not needed, and the risk of such diverted traffic flows themselves causing overloads is reduced. It can be applicable to a range of causes of overload, including denial of service attacks.
摘要翻译：为了管理具有SDN控制器（10）的软件定义网络（70）中的业务过载，当接收到业务过载的指示（200）时，存在识别（208）有助于此的交通流量的步骤，识别（210）节点（20,21,22），其可由SDN控制器控制并且沿着所识别的业务流的路径在流量过载的位置之前定位。 SDN控制器用于控制（220）所识别的节点，以控制识别的流量，以减少流量过载。通过使用SDN控制器来控制与将可疑流量转向单独的外部安全服务器相比的减少，不需要用于承载转移流量的额外网络资源，不需要单独的安全服务器，并且存在这样的风险转向流量本身导致过载减少。它可以适用于一系列过载的原因，包括拒绝服务攻击。
