Modular Industrial Automation Device and Method for Configuring a Modular Industrial Automation Device
Modular industrial automation device and method for configuring a modular industrial automation device, wherein in order to configure the modular industrial automation device which includes a central unit and at least one communication module which each comprise a router module and a routing configuration unit, the routing configuration units transmit routing information stored in their routing table to routing configuration units of other router modules, and the routing configuration units update their respective routing table based on routing information which is received from routing configuration units of other router modules and relates to routes to IPv4 subnetworks assigned to other router modules, a default gateway and a connection between the associated router module and a backplane bus system.
BROADCAST SIGNAL TRANSMISSION APPARATUS, BROADCAST SIGNAL TRANSMISSION METHOD, BROADCAST SIGNAL RECEPTION APPARATUS AND BROADCAST SIGNAL RECEPTION METHOD
A broadcast signal transmission method comprises outputting an RoHC channel that includes one or more RoHC streams and a signaling table that includes information related to header compression by performing header compression for Internet Protocol (IP) packets, which include broadcast data, in accordance with an adaptation mode, a header of each IP packet including an IP header and a User Datagram Protocol (UDP) header, generating at least one first link layer packet that includes the RoHC channel and generating at least one second link layer packet that includes the signaling table, and physical layer processing the at least one first link layer packet and the at least one second link layer packet and transmitting through one or more Physical Layer Pipes (PLPs), wherein the signaling table includes adaptation mode information indicating the adaptation mode, and each RoHC stream in the RoHC channel includes RoHC packets.
Managing bandwith in fibre channel over internet protocol communication channels
Methods and systems include managing bandwidth in Fibre Channel over Internet Protocol (FCIP) communication channels. A method includes monitoring traffic demand at an FCIP communication channel and, in response to an anticipated period of throughput demand on the FCIP communication channel, reallocating physical throughput bandwidth of the FCIP communication channel by configuring bandwidth of one or more tunnels of the FCIP communication channel.
Transmission apparatus, transmission method, reception apparatus, and reception method
The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that enable channel selection information and time information to be transmitted effectively. A transmission apparatus acquires channel selection information for selecting a service and time information used for synchronizations on a transmission side and a reception side, generates, as a physical layer frame constituted of a preamble and a data portion, the physical layer frame in which specific information including at least one of the channel selection information and the time information is arranged at a head of the data portion right after the preamble, and transmits the physical layer frame as digital broadcast signals. The present technology is applicable to IP packet broadcasting, for example.
MANAGING BANDWITH IN FIBRE CHANNEL OVER INTERNET PROTOCOL COMMUNICATION CHANNELS
Methods and systems include managing bandwidth in Fibre Channel over Internet Protocol (FCIP) communication channels. A method includes monitoring traffic demand at an FCIP communication channel and, in response to an anticipated period of throughput demand on the FCIP communication channel, reallocating physical throughput bandwidth of the FCIP communication channel by configuring bandwidth of one or more tunnels of the FCIP communication channel.
COALESCING PACKETS WITH MULTIPLE WRITERS IN A STATELESS NETWORK FUNCTION
A method including receiving a batch of events at a processing system of a distributed stream processing system including multiple processing systems in data communication with a shared state data store. The method also can include determining, at the processing system, database operations associated with the events. The method additionally can include coalescing, at the processing system, the database operations into one or more speculative database operations with one or more associated reject rules. The processing system stores a speculative state of at least a portion of the shared state data store. The one or more associated reject rules are based on the speculative state. The method further can include sending the one or more speculative database operations and the one or more associated reject rules from the processing system to the shared state data store to cause the shared state data store to determine whether to reject one or more of the one or more speculative database operations based on an authoritative state in the shared state data store. The method additionally can include receiving, at the processing system, one or more responses from the shared state data store. Other embodiments are described.
Roaming by binding a host with a device identifier
Roaming methods and hosts are provided. In the present disclosure, a TCP/IP connection established between a host and an opposite end is modified from binding a first IP address of the host in a current first network to binding a host address within the first IP address which does not change during host roaming, so that all parameters associated with the TCP/IP connection established between the host and the opposite end do not change when the host roams from the first network to a second network.
METHODS AND APPARATUSES FOR ENABLING MULTI-HOST MULTIPATH SECURE TRANSPORT WITH QUIC
Methods and apparatuses for enabling multi-host multipath secure transport with Quick User Datagram Protocol (UDP) Connections (QUIC) are described herein. A method performed by a client endpoint may involve sending, to a network node, a request to establish a QUIC connection with a destination endpoint, the request to establish the QUIC connection including a flow identifier (ID). The method may involve receiving, from the network node, a response including an indication that the request to establish the QUIC connection with the destination endpoint is accepted. The method may involve encapsulating inner QUIC packetized data within outer QUIC packetized data, the inner QUIC packetized data including the flow ID. The method may involve sending, to the network node, the outer QUIC packetized data for forwarding toward the destination endpoint based on the flow ID.
WIRELESS DEVICE OF A WIRELESS LOCAL AREA NETWORK COMMUNICATING WITH A DEVICE OF AN EXTERNAL NETWORK ON A TCP SESSION BEFORE AND AFTER DISASSOCIATION FROM THE WIRELESS LOCAL AREA NETWORK
A wireless station associates with an access point to join a wireless local area network (WLAN). The access point is part of the WLAN and operates as a switching device between wireless stations of the WLAN. The wireless station forms a TCP session via the access point with an external device which is external to the WLAN. The wireless station exchanges (i.e., transmits and/or receives) a first sequence of packets on the TCP session. The wireless station receives a frame from the access point, the frame indicating that the wireless station has been disassociated after having associated earlier with the access point. The wireless station re-associates with the access point. The access point then communicates with the external device on the TCP session after re-associating, the communicating involving exchanging a second sequence of packets with the external device after the re-association.
Transmission apparatus, transmission method, reception apparatus, and reception method
A transmission apparatus that includes circuitry configured to generate transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard; and transmit, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information, and the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport).
