A method, a system and a storage medium for network failure protection belonging to the field of network technologies. The method comprises: allocating, for each forwarding link of the ring topology, a protection ring bit position opposite to the direction of a working path; newly adding BRFT for storing adjacent forwarding table entries related to forwarding along the direction of the protection ring bit position; and when a BIER message is forwarded along the working path, if a BFR detects that the downstream adjacency fails, searching for entry content of the BTAFT, finding the correlation between the link bit position of the fault forwarding link and the protection ring bit position, and forwarding, on the basis of entry content of the BRFT, the BIER message to the opposite end fault point of the opposite end along the direction of the protection ring bit position.

A communication network includes relaying apparatuses, each including redundant-route ports providing communication routes between the relaying apparatuses. The relaying apparatus determines whether a first frame received via a usual port is highly important. The first frame being highly important is transmitted via the respective redundant-route ports; the first frame being not highly important is transmitted via one redundant-route port. The relaying apparatus receives a second frame being highly important via the respective redundant-route ports; the second frame has a transmission destination corresponding to an apparatus connected with the relaying apparatus via the usual port. The relaying apparatus makes determination whether or not all the second frames received via the respective redundant-route ports accord with each other. With affirmative determination, one of the second frames is transferred to the transmission destination. With negative determination, all the second frames are cancelled.

Method for operating a network having a prescribable topology, wherein the topology contains a plurality of network devices which are connected to one another and interchange data via multiwire data lines connected to their data ports, wherein test messages are also sent to the data lines in order to check whether or not two data ports on two network devices have the connection between them via the interposed data line, characterized in that, in a prescribable time interval, the number of cyclic redundancy check (CRC) errors which have occurred and the number of data items transmitted in this time interval are ascertained on a data line between two data ports, and at least these two values are used to calculate an error rate which is a measure of the operability of the multiwire data line.

An information processing device includes an acquisition unit that acquires information about sidelink communication, and a determination unit that determines whether to enable feedback related to a data automatic repeat request in the sidelink communication based on the information about the sidelink communication.

A robotic surgical system is disclosed having a ring network for communicating information between a controller and nodes of one or more robotic arms. A communications protocol is described by which synchronous and asynchronous information can be communicated to and from the nodes of the robotic arms. Also disclosed are various aspects of a physical layer that can be used with the network.

Fifth Generation (5G) Millimeter Wave (mmWave) cellular networks are expected to serve a large set of throughput intensive, ultra-reliable, and ultra-low latency applications. To meet these stringent requirements, while minimizing the network cost, the 3.sup.rd Generation Partnership Project has proposed a new transport architecture, where certain functional blocks can be placed closer to the network edge. In this architecture, however, blockages and shadowing in 5G mmWave cellular networks may lead to frequent handovers (HOs) causing significant performance degradation. To meet the ultra-reliable and low-latency requirements of applications and services in an environment with frequent HOs, a Fast Inter-Base Station Ring (FIBR) architecture is described, in which base stations that are in close proximity are grouped together, interconnected by a bidirectional counter-rotating buffer insertion ring network. FIBR enables high-speed control signaling and fast-switching among BSs during HOs, while allowing the user equipment to maintain a high degree of connectivity. The FIBR architecture efficiently handles frequent HO events in mm Wave and/or Terahertz cellular systems, and more effectively satisfies the QoS requirements of 5G applications.

Reception information of frames received at a redundant port may be stored to a data structure in group of data structures such that reception information of all frames in a sequence are not stored to the same data structure and the reception information can be quickly accessed for duplicate detection. The data structure includes reception information for a portion of consecutive frames in a sequence of frames transmitted by a specific transmitter node. A communications layer address of the transmitter node and information capable of identifying a portion of consecutive frames in a sequence of frames are derived from a received frame. The reception information for the received frame in the data structure is read on the basis of derived information capable of identifying the received frame within the portion of consecutive frames.
