Abstract: Various embodiments providing for an indicator (termed the “Traffic Category Indicator,” TCI) to be encoded into packets, different values of which can be used, e.g., to distinguish Traffic Engineered (TE) packets and non-TE packets. In an example embodiment, the TCI can be used, e.g., to configure a network node to implement different packet queues, on each link, for TE packets and non-TE packets. In embodiments corresponding to the DiffSery TE paradigm, a node can be configured to implement different queues within each Forwarding Class for each link, said different queues distinguished by different respective TCI values. Example benefits of TCI include, but are not limited to fate separation of TE and non-TE packets in a node. The TCI concept can beneficially be applied to different packet-switching technologies supporting Source Routing, such as the IP, MPLS, Ethernet, etc.

Abstract: A method for implementing load balancing are applied to a 4-node network structure. Every two nodes in the 4-node network structure are interconnected, and the nodes are, e.g., dies. The 4-node network structure includes a source node (SN) and a destination node (DN). According to the method, when a bandwidth occupied by ingress traffic flowing into the SN and destined for the DN is greater than a bandwidth of a fabric side link (FSL) between the SN and the DN, the SN selects at least two transmission paths to send the ingress traffic to the DN; and when the bandwidth occupied by the ingress traffic is less than or equal to the bandwidth of the FSL, the SN transmits the ingress traffic on a direct link between the SN and the DN.

Abstract: A layer 2 (L2) modem provides traffic handling for low latency (LL) traffic. A filter is selected from an application traffic filter list. The filter determines LL traffic that is received and uses a DSC messaging process is used add a classifier for directing the LL traffic to the LL SF. If LL traffic associated with an LL traffic filter of the classifier begins to buildup in a queue, the LL traffic filter is removed from the classifier. This information is provided to a LL controller server that refines the application traffic filter list used to create the classifier. When LL traffic has not been received for a predetermined time, the classifier is removed. Once LL traffic is again detected by the L2 modem filters, a classifier is again added.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques performed at a user equipment (UE) provide for communicating directly with a base station using a first set of antennas and communicating indirectly with the base station (e.g., via a wireless node, a remote radio head, etc.) using a second set of antennas to fully exploit the potential capabilities of the physical antennas at the UE. For downlink communications, a UE may receive at least a subset of downlink signals from a base station via a wireless node, and, for uplink communications, the UE may transmit at least a subset of uplink signals to the base station via a wireless node. To facilitate these techniques, the UE may configure the wireless node to forward downlink signals received from the base station to the UE or to forward uplink signals received from the UE to the base station.

Abstract: In one embodiment, a device computes states of a network path associated with an online application by representing time series of telemetry data regarding the network path as discrete values. The device generates state trajectories from the states of the network path computed by the device. The device selects one or more sub-sequences of the state trajectories based on prediction performance metrics that represent how well the one or more sub-sequences are able to predict a failure condition of the network path. The device causes a networking entity to use the one or more sub-sequences of the state trajectories to perform predictive routing for the network path.

Abstract: Systems and methods implement multi-channel communication by remapping Ethernet frames. An Ethernet frame is captured leaving a first bridge of an Ethernet switch. A destination address of the Ethernet frame is matched to a remap rule and to a filter defined for the remap rule. The destination address of the Ethernet frame is updated based upon the remap rule, and the Ethernet frame is output to an Ethernet port corresponding to the updated destination address of the Ethernet frame. The remap rule and the filter allow the Ethernet switch to route traffic at an OSI model layer-4 level.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for configuration of time-sensitive networks. Time-sensitive networks utilize traffic shaping to provide for efficient and predictable flows of data through the network. A network configuration tool can be used to determine how data should be routed and shaped through the network towards its destination. The network configuration tool calculates the maximum burst size at an output port of a switch by analyzing groups of data flows that pass through the output port, rather than analyzing the data flows individually.
