摘要： An example method comprises establishing, via a first data communication interface of a first computing device, a physical connection to between the first computing device and a second computing device. The method also includes receiving, at the first computing device, input data via a second data communication interface of the first computing device. The method further includes controlling an operation at the first computing device based on the input data when the input data is received prior to establishing the connection. The method further includes routing the input data to the second computing device via an input data switch of the first computing device when the input data is received after establishing the connection.

摘要： In one aspect, a wireless transmitter forms (1110) a first signal having a first integer number of symbol intervals in each of one or more time intervals of a predetermined length and forms (1120) a second signal having a second integer number of symbol intervals in each of the one or more time intervals of the predetermined length, the second integer number differing from the first integer number. The wireless transmitter simultaneously transmits(1130) the first and second signals in a frequency band, such that the first and second signals are frequency- domain multiplexed in the frequency band and such that a symbol interval starting time in the first signal is aligned with a corresponding symbol interval starting time in the second signal at least once per time interval.

摘要： In an embodiment, a plurality of hardware buffers each may store information associated with one or more virtual channels. In turn, a configuration logic is to determine an identifier corresponding to a maximum number of virtual channels commonly supported by first and second devices coupled via a link and to obtain a control value based on the identifier. A gate logic coupled to the configuration logic is to provide an operating voltage to corresponding ones of the hardware buffers based on the control value. In this way, the operating voltage can be withheld from at least one of the hardware buffers when the maximum number of virtual channels is less than the plurality of hardware buffers. Other embodiments are described and claimed.

摘要： This disclosure provides systems, methods, and apparatus for providing a crosspoint switch used in an optical fiber data network. The crosspoint switch can switch optical signals received from any of a plurality of input optical fibers to any one of a plurality of output optical fibers. The crosspoint switch converts the optical signals received from the input optical fibers into electrical signals, switches the electrical signals, and converts the switched electrical signals back into optical signals before transmitting them over the output optical fibers. A micro-electromechanical systems (MEMS) electrical switch array is utilized to switch the electrical signals. The MEMS electrical switch array includes MEMS switching elements that allow for high frequency and high bandwidth operation of the crosspoint switch. The crosspoint switch can utilize circuit switching methodology for switching decisions.

摘要： Example implementations described herein are directed to automatically determine an optimal NoC topology using heuristic based optimizations. First, an optimal orientation of ports of various hosts is determined based on the system traffic and connectivity specification. Second, the NoC routers to which the host's port are directly connected to are determined in the NoC layout. Third, an optimal set of routes are computed for the system traffic and the required routers and channels along the routes are allocated forming the full NoC topology. The three techniques can be applied in any combination to determine NoC topology, host port orientation, and router connectivity that reduces load on various NoC channels and improves latency, performance, and message transmission efficiency between the hosts.

摘要： Systems disclosed herein may allocate buffer space using methods, which prevent other resource allocation methods from apportioning the other resources in a way that inhibits system needs from being met. As such, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on the traffic priority class that each allocated buffer will handle. Alternatively, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on the bandwidth needs of each respective buffer being allocated. Alternatively still, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on a function of the traffic priority class that each allocated buffer will handle and the bandwidth needs of each respective buffer being allocated.

摘要： Flow control of data packets in a network may be enabled to at least one side of a virtual switching interface to provide a lossless environment. In some embodiments, wherever two buffer queues are in communication with at least one buffer queue being connected to a virtual switching interface, flow control may be used to determine if a threshold has been exceeded in one of the buffer queues. When exceeded, the transmission of data packets may cease to one of the buffer queues to prevent packet dropping and loss of data.

摘要： Disclosed are methods, systems, paradigms and structures for processing data packets in a communication network by a multi core network processor. The network processor includes a plurality of multi-threaded core processors and special purpose processors for processing the data packets atomically, and in parallel. An ingress module of the network processor stores the incoming data packets in the memory and adds them to an input queue. The network processor processes a data packet by performing a set of network operations on the data packet in a single thread of a core processor. The special purpose processors perform a subset of the set of network operations on the data packet atomically. An egress module retrieves the processed data packets from a plurality of output queues based on a quality of service (QoS) associated with the output queues, and forwards the data packets towards their destination addresses.
