摘要： With multiple connections (20) communicatively coupling a User Equipment (UE) (12) to a wireless communication network (10), methods and apparatuses disclosed for performing flow control at the Radio Link Control (RLC) level advantageously control the shares of overall data conveyed on the respective connections (20) in a manner that accounts for changing conditions on the involved radio links (22) while accommodating signaling delays and other complexities that arise from distributed or virtualized implementations of the underlying processing apparatuses (18). The disclosed methods and apparatuses have applicability both to uplink multi-connectivity and downlink multi-connectivity, and apply to various multi-connectivity scenarios, including scenarios involving mixed Radio Access Technologies (RATs) and Carrier Aggregation (CA) configurations that aggregate two or more Component Carriers (CCs) for carrying user traffic between a UE (12) and the network (10).

摘要： Current data center deployments, particularly layer 2 (L2) deployments that use multi-chassis link aggregation group (MC-LAG) implementations, have limitations. Such deployments use a link, known as an inter-node link (INL)/inter-chassis link (ICL), to connect peer information handling system nodes. Because the peer nodes are coupled together via one or more INL connections, there are fewer ports available for each peer node to connect to end nodes. This configuration creates limitations to bandwidth and scaling, and also increase costs. Embodiments herein allow for the elimination of INLs by moving forwarding decisions to the spine node level. In one or more embodiments, a spine node determines ports to reach dual-homed, single-homed, and orphaned node that are connected to leaf node(s) based on information learned from the leaf nodes. For a leaf node, a sub-LAG (link aggregation group) may be created to reach single-homed/orphaned nodes connected to the leaf node.

摘要： Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a CIC value field in signaling information of a communication to provide an identification of the ingress network to an egress or receiving network of a long distance telecommunications network. The system and method provides for the provisioning of a signaling CIC for an ingress trunkgroup or network to a telecommunications network for downstream signaling purposes by overriding a received CIC value with a provisioned CIC value specific to the ingress network. This provisioned CIC value identifies the ingress network to the long distance network to the egress network for use by the egress network.

摘要： Embodiments of the invention provide efficient ways to transmit Broadcast, unknown Unicast, or Multicast (BUM) traffic for multiple Ethernet Virtual Private Network (EVPN) Instances (EVIs). In one embodiment, a method is performed by a network device, the method comprises identifying a plurality of sets of network devices, each set of network devices to include network devices belonging to one Ethernet Virtual Private Network (EVPN) Instance (EVI) of a plurality of EVIs, for which the network device serves as an ingress network device; selecting an aggregation set of network devices from the identified network devices to set up an aggregation tunnel label switched path (LSP) for multiple EVIs of the plurality of EVIs; and transmitting broadcast, unknown unicast, or multicast (BUM) traffic for the multiple EVIs using the aggregation tunnel LSP.

摘要： A method is executed by a network device for implementing conversation-sensitive collection for frames received on a port of a link of a link aggregation group. The network device executes an aggregator to collect the frames for aggregator clients, where each frame is associated with a service identifier and a conversation identifier. The service identifier identifies a data flow at a link level for a service. The conversation identifier identifies the data flow at a link aggregation group level, where each conversation data flow consists of an ordered sequence of frames, and where the conversation-sensitive collection maintains the ordered sequence by discarding frames of conversations not allocated to the port.
