A switch architecture enables ports to stash packets in unused buffers on other ports, exploiting excess internal bandwidth that may exist, for example, in a tiled switch. This architecture leverages unused port buffer memory to improve features such as congestion handling and error recovery.

Transfer apparatuses perform communications for path control with a centralized control apparatus that performs centralized control from the outside of a switch cluster including the group of transfer apparatuses, through a path similar to D-plane (main signal). A packet flow controller serving as a separation unit that separates a packet for the inside of the cluster and a packet for the outside of the cluster transmitted through the similar path from each other, and an internal route engine that performs path control of obtaining a path for freely passing through a plurality of paths in the cluster are provided. The packet flow controller separates a path control packet for the inside of the cluster, and the engine performs, when a failure to communicate the path control packet for the inside thus separated occurs, path control of generating a path that bypasses a path with the failure.

A method is proposed for operating a network with multiple subscribers in the network. For this purpose, a network having at least one switch (20, 21), at least two terminals (10, 11, 12) and a controller (30) is provided. According to the invention, one of the subscribers now sends and/or receives data to another subscriber via an application protocol, with the data being sent and/or received as a TSN data stream. In order to integrate non-TSN-capable nodes in the network, it is proposed that the TSN data stream be divided into at least two partial data streams (1, 2, 3, 4). Such partial data streams (1, 2, 3, 4) can be configured across non-TSN-capable subscribers or between such subscribers.

Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A computing system includes multiple fabric interfaces in clients and a fabric. A packet transmitter in the fabric interface includes multiple queues, each for storing packets of a respective type, and a corresponding address history cache for each queue. Queue arbiters in the packet transmitter select candidate packets for issue and determine when address history caches on both sides of the link store the upper portion of the address. The packet transmitter sends a source identifier and a pointer for the request in the packet on the link, rather than the entire request address, which reduces the size of the packet. The queue arbiters support out-of-order issue from the queues. The queue arbiters detect conflicts with out-of-order issue and adjust the outbound packets and fields stored in the queue entries to avoid data corruption.

Method and apparatus for monitoring the status and location of personnel using a remote timer. In some embodiments, a system is provided having a network accessible device with a controller, a memory and a native sensor. A subject application (app) is installed as native programming by an original manufacturer of the network accessible device and has access to the native sensor. A timer circuit of a remote server initiates a monitored elapsed time interval responsive to execution of the subject app, and sends a notification signal to a monitoring device responsive to a conclusion of the monitored elapsed time interval without having received a disable communication from the network accessible device. The disable communication is generated by a biometric input supplied by a user of the network accessible device via the native sensor, with the biometric input serving as a personal identification (PID) for the user.

A system includes a storage system and circuitry coupled to the storage system. The circuitry is configured to perform operations comprising determining a type of a received data packet, determining a destination of the received data packet, and determining whether the received data packet is of a particular type or has a particular destination. The operations further comprise, responsive to determining that the received data packet is of the particular type or has the particular destination, rerouting the received data packet from the particular destination to a register of the storage system.

Devices and techniques for packet arbitration for buffered packets in a network device are described herein. A packet can be received at an input of the network device. The packet can be placed in a buffer for the input and a characteristic of the packet can be obtained. A record for the packet, that includes the characteristic, is written into a data structure that is independent of the buffer. Arbitration, based on the characteristic of the packet in the record, can then be performed among multiple packets to select a next packet from the buffer for delivery to an output.

Embodiments of the present disclosure relate to software-defined networks, and particularly, but not exclusively to programmable packet data processing systems, methods and computer readable products for use therein.

A method for setting up forwarding tables is described. A USAT part for a node is received. The USAT part includes glow definitions and a FGPL. Each glow describes network traffic flows and role instructions for the flows. Each FGP describes a role for the switching node; a validity rule; and relevant network topology. The method also includes determining a selected active FGP in the FGPL using the validity rule for the FGP, a network state and the ordering of the FGPs; initializing the glows, requesting a role identification to perform based on the selected FGP, determining the role instructions and instructing the TMS to update tables accordingly; and storing entries in software tables based on glows and the role instructions for the identified role, dynamically resolving conflicts among entries, and granting table updates to hardware tables. The tables include a software table for each hardware memory for forwarding packets.

A method for a time sensitive network (TSN) having a network topology is disclosed. The method includes determining a set of data flow permutations corresponding to the network topology, computing a respective full schedule corresponding to each data flow permutation of the set of data flow permutations, determining a respective time to compute the full schedule for each flow permutation of the set of data flow permutations, and computing a respective partial schedule for each data flow permutation of the set of data flow permutations. The method further includes selecting a data flow permutation of the set of data flow permutations based at least in part on the respective time to compute the full schedule for the selected flow permutation, and saving the selected data flow permutation to a memory.
