Abstract: In some implementations, a network device may identify a segment routing traffic engineering (SR-TE) algorithm supported by the network device. The network device may determine, based on identifying the SR-TE algorithm, an identification value associated with the network device. The network device may generate an advertisement packet that includes the identification value and information identifying the SR-TE algorithm. The network device may send the advertisement packet to another network device to cause the other network device to update a data structure to indicate that the network device supports the SR-TE algorithm and that the network device is associated with the identification value. The other network device may determine, using the SR-TE algorithm, a forwarding path for a data packet that indicates the network device as a hop in the forwarding path.

Abstract: A method of simplifying the implementation of Synchronous Ethernet on an Ethernet device having a first port and a second port device using a predetermined protocol and signaling, comprises delivering a master clock from a Synchronous Ethernet system to the first port of the Ethernet device; transmitting the delivered master clock to the second port of the Ethernet device independently of the protocol and signaling of the Ethernet device; and transmitting the master clock from the second port of the Ethernet device to a downstream device that supports Synchronous Ethernet. In one implementation, the Ethernet device has a local clock, and the method synchronizes the local clock to the master clock. In another implementation, the Ethernet device does not have a local clock, and the master clock is transmitted from the second port of the Ethernet device to the downstream device without any synchronizing operation at the Ethernet device.

Abstract: In certain embodiments, a 5G RAN network has a distributed unit (DU) connected to at least one remote unit (RU) via a transport network (TN) that handles both mobile front-haul (MFH) traffic between the DU and the RUs as well as non-MFH traffic with other end users. A radio scheduler in the DU is configured to perform medium access control (MAC) scheduling for the mobile user traffic, while a TN scheduler in the transport network is configured perform TN scheduling for both the MFH and non-MFH traffic. The TN scheduler is configured to transmit information (e.g., MFH data-rate limits) to the radio scheduler that the radio scheduler uses to perform its subsequent MAC scheduling.

Abstract: Aspects relate to a physical cell identifier (PCI) change within a wireless network based on a primary synchronization signal (PSS) waveform. A scheduling entity, such as an integrated-access-backhaul (IAB) node within a radio access network (RAN), may communicate with a set of one or more scheduled entities, such as other IAB nodes and/or user equipment (UEs), utilizing a first PCI. The scheduling entity may then change from the first PCI to a second PCI, where the second PCI corresponds to a different PSS waveform than the first PCI. In some examples, the scheduling entity may change the PCI as a result of a PCI collision and/or PSS collision with a neighboring scheduling entity.

Abstract: Implementations of the present disclosure are directed to systems and methods for flow control using a multiple flit interface. A credit return field is used in a credit-based flow control system to indicate that one or more credits are being returned to a sending device from a receiving device. Based on the number of credits available, the sending device determines whether to send device or wait until more credits are returned. The amount of buffer space used by the receiver to store the packet is determined by the number of transfer cycles used to receive the packet, not the number of flits comprising the packet. This is enabled by having the buffer be as wide as the bus. The receiver returns credits to the sender based on the number of buffer rows used to store the received packet, not the number of flits comprising the packet.

The method may further include identifying, in response to determining that the signal quality does not satisfy the signal quality threshold or the congestion does not satisfy the throughput threshold, another path for the UE device to use when communicating with the anchor station.

Abstract: This document describes methods, devices, systems, and means for user-equipment-coordination-set (404) control aggregation that facilitates more efficient control-plane signaling in comparison to conventional wireless communication systems. Overhead for control-plane signaling is reduced by communicating reports and control commands for the multiple user equipments (110) in the user-equipment-coordination-set (404) in a single message instead of communicating a single control message for each user equipment (110). Additionally, the user-equipment-coordination-set (404) uses joint-reception and joint-transmission, to increase the reliability of communicating reports and control commands, especially in the case of challenging radio communication conditions between a base station (121) and an individual UE (110) located near the edge of a cell provided by the vase station.

Abstract: The present disclosure provides packet aggregation and disaggregation methods. In the packet aggregation methods, the protocol-independent packet processor (P4) switch stores plural message headers of plural packets in the ring buffer. When the plural message headers stored in the ring buffer reach a pre-defined amount of data, the P4 switch replaces the first flag header in the current packet with a second flag header so as to form a work packet. The egress pipeline of the P4 switch recirculates the work packet repeatedly, whenever it receives a work packet, a message header is extracted from a plurality of message headers in the ring buffer and added to the working packet for packet aggregation.

Abstract: A data link layer device and a packet encapsulation method are provided. The data link layer device includes a first and a second first-in-first-out (FIFO) module. The first FIFO module receives and stores multiple first data from an upper-layer module, and removes data gaps from the first data to store the first data in a continuous form. When the first FIFO module is not empty, the first FIFO module generates data of different lengths based on the current amount of data stored temporarily in the first FIFO module and a preset data length. When the data queue of the second FIFO module has enough space to receive the first data, the first FIFO module transfers the first data to the second FIFO module, and the first FIFO module transfers a header including the data length to a header queue of the second FIFO module.

Abstract: A base station transmits and a UE detects broadcast information when the UE operates in a Coverage Enhancement (CE) mode. The base station transmits repetitions of signaling conveying broadcast information in one or more subframes of each frame in a quadruple of frames. The transmission is intermittent in time. To detect the broadcast information, the UE blindly combines and decodes the repetitions of signaling assuming their existence. The base station informs the pattern for the intermittent transmissions of the signaling to UEs connected to the base station or to other base stations.

Abstract: A method and system for authorizing traffic flows in a computer network. The method including: receiving a packet from a traffic flow sent by a sender; determining whether the traffic flow has been previously authorized; if the traffic flow has not been previously authorized: determining a subscriber associated with the traffic flow, based on the data retrieved from the packet; requesting authorization from an authorization server based on the subscriber and the data retrieved from the packet; upon receiving a response from the authorization server, sending at least three duplicate acknowledgments to the sender, to generate a retransmission in advance of the standard retransmission timing; otherwise, if the traffic flow has been previously authorized, allowing the packet to continue to a destination.

Abstract: A method and apparatus for routing packets in a network, such as a satellite mesh network. For each one of multiple destination devices capable of further handling of the packet for routing to a destination (e.g. ground station) a respective cost or utility associated with forwarding the packet to that destination device is determined. For a given value k, an unsorted subset of k of the destination devices for which said costs are lowest or said utilities are highest is determined, without necessarily fully sorting the plurality of destination devices by cost or utility. The data packet is then forwarded to a selected one of this subset of destination devices. Cost may correspond to distance from destination device (e.g. satellite) to the further destination. Sorting networks and selector networks can be used, for example as implemented in hardware, to generate the unsorted subset.

Abstract: The present disclosure pertains to improving resilience to single event upsets (“SEUs”) in a software-defined network (“SDN”). In one embodiment, a system may include a communications interface to receive and transmit a data packet. A primary data flow repository may store a plurality of communication flows to be used to route the data packet. A secondary data flow repository may store a subset of communication flows to be used to route a data packet. A system may search the plurality of communication flows in the primary data flow repository based on a criteria associated with the data packet. If no communication flow satisfies the criteria, a secondary data flow repository may be searched. The data packet may be routed according to a communication flow in the secondary data flow repository. The communication flow from the secondary data flow repository may be duplicated in the primary data flow repository.

Abstract: Method, device, and system for providing hot reservation for in-line deployed network functions with multiple network interfaces. A system includes a first Network Function (NF) unit, connected to an ingress router and to an egress router; and a second NF unit, connected to the ingress router and to the egress router. The first NF unit is initially configured as a controlling NF. The second NF unit is initially configured as a backup NF. The two NF units periodically exchange keep-alive messages via the two routers. The second NF unit, operating as the backup NF, automatically triggers a switchover if the second NF unit did not receive a keep-alive message from the first NF unit for at least a pre-defined time-period. Additionally or alternatively, the controlling NF initiates a switchover if the maintenance status parameters of the backup NF are better than those of the controlling NF.
