Abstract: A communication method, and a communication apparatus are provided. A first network apparatus forwards traffic based on a first forwarding entry in response to a determination that the first forwarding entry for forwarding traffic is not aged. The first network apparatus sends a first packet, in response to a determination that the first network apparatus is a network apparatus performing traffic switchover, to a third network apparatus so that the third network apparatus is to regenerate a forwarding path to reach a target network apparatus through the second network apparatus. The third network apparatus is an apparatus accessed by both the first network apparatus and the second network apparatus, and a path from the third network apparatus to the first network apparatus and a path from the third network apparatus to the second network apparatus are equal-cost paths.

Abstract: A computer-implemented method optimizes a routing of data traffic in a communications network by using a quantum concept processor. A set of potential short communication paths among possible communication paths between respective origin nodes and respective destination nodes of captured traffic demands is specified. The edges within the set of potential short communication paths are assigned a respective usage capacity limit. Fractional capacity usages of the edges are calculated based on respective usage capacity limits of the edges. The calculated fractional capacity usages are formulated as terms of a quadratic stress function. An optimized routing is determined by using a quantum concept processor, thereby selecting for each traffic demand one short communication path from the set of potential short communication paths such that the quadratic stress function is minimized.

Abstract: Techniques for a Software-Defined Networking (SDN) controller associated with a multisite network to implement jurisdictional data sovereignty polices in a multisite network, route network traffic flows between user sites and destination services over one or more provider sites, and/or perform a routing operation on the network traffic flow(s) based on the jurisdictional data sovereignty policies. The jurisdictional data sovereignty polices may be implemented using destination group tags (DGTs) and/or source group tags (SGTs). A secure access service edge (SASE) associated with the network controller may generate, store, and distribute the DGTs to provider sites and/or the SGTs to user sites. Based on the SGT and/or DGT associated with a network traffic flow, one or more services may be applied to the network traffic flow, and the network traffic flow may be routed through a particular region of a software-defined access (SDA) transit.

Abstract: A network interface controller (NIC) capable of efficient packet forwarding is provided. The NIC can be equipped with a host interface, a packet generation logic block, and a forwarding logic block. During operation, the packet generation logic block can obtain, via the host interface, a message from the host device and for a remote device. The packet generation logic block may generate a plurality of packets for the remote device from the message. The forwarding logic block can then send a first subset of packets of the plurality of packets based on ordered delivery. If a first condition is met, the forwarding logic block can send a second subset of packets of the plurality of packets based on unordered delivery. Furthermore, if a second condition is met, the forwarding logic block can send a third subset of packets of the plurality of packets based on ordered delivery.

Abstract: In one embodiment, a device obtains quality of experience metrics for an online application whose traffic traverses a particular interface of a router located at a first site in a network. The device identifies a correlation between throughput of the particular interface and the quality of experience metrics for the online application. The device makes a determination that the correlation is a root cause of degradation of the quality of experience metrics for the online application at least in part by determining whether throughput of an interface of a remote router located at a second site in the network is correlated with the quality of experience metrics. The device configures, based on the determination, a priority queue associated with the particular interface for use by traffic of the online application.

Abstract: In one embodiment, a controller features a first data store, a second data store and route determination logic. The first data store is configured to store current routing information from a source transit gateway within at least a first transit cloud network to a destination transit gateway within at least a second transit cloud network of the cloud network. Each of the source transit gateway and the destination transit gateway being one of a plurality of transit gateways associated with the cloud network. The second data store is configured to store alternative routing information between the source transit gateway and the destination transit gateway. The route determination logic is configured to (i) conduct analytics on all available route paths for a message intended to be sent from the source transit gateway to the destination transit gateway and (ii) select a best route path for the message.

Abstract: An assignment of demands to routes on a communication network can be improved by selecting and updating a subset of the routes. A network management system (or other communication network component) can obtain a representation of the communication network. The representation can include a network graph, sets of resources, and a set of paths for the network graph. The network management system can update the set of paths by selecting a path subset and updating the paths of the path subset. The updating can satisfy a total change condition and a network improvement condition. The updating can be limited to unused edge and resource combinations or edge and resource combinations used by paths in the path subset. The network management system can configure the communications network to satisfy the demand using routes corresponding to the updated set of paths.

Abstract: Systems and methods for zero touch configuration for a mesh of nodes using Segment Routing Flexible Algorithm define a Flex Algo Definition (FAD) of an auto-mesh plane. A method, in one embodiment, includes, responsive to the FAD, providing an advertisement of a Prefix Segment Identifier (SID) for a node in the auto-mesh plane; and including a flag in the advertisement designating whether the node is a destination node or a non-destination node in the auto-mesh plane. The destination node is one which requires transport connectivity to all other destination nodes in the auto-mesh plane, and the non-destination node is one used for reachability to all the destination nodes.
