Abstract: A first network device may receive a first advertisement of a network destination from a second network device and may detect multihoming with the second network device. The second network device may detect the multihoming with the first network device. The first network device and the second network may enable egress protection for the multihoming. The first network device may allocate, from a first pool, a protection group identifier for a group of multihomed network devices and may allocate, from a second pool, a network destination identifier for the network destination. The first network device may provide, to a network and the second network device, a second advertisement that includes the protection group identifier and the network destination identifier. The protection group identifier and the network destination identifier may cause the network to direct traffic for the network destination, via the group of multihomed network devices.

Abstract: A network management system (NMS) is described that provides a granular troubleshooting workflow at an application session level using an application session-specific topology from a client device to a cloud-based application server. During an application session of a cloud-based application, a client device running the application exchanges data through one or more access point (AP) devices, one or more switches at a wired network edge, and one or more network nodes, e.g., switches, routers, and/or gateway devices, to reach a cloud-based application server. For a particular application session, the NMS generates a topology based on network data received from a subset of network devices, e.g., client devices, AP devices, switches, routers, and/or gateways, that were involved in the particular application session over a duration of the particular application session. In this way, the NMS enables backward-looking troubleshooting of the particular application session.

Abstract: Techniques for EVPN Host Routed Bridging (HRB) and EVPN cloud-native data center with Host Routed Bridging (HRB) are described. A host computing device of a data center includes one or more containerized user-level applications. A cloud native virtual router is configured for dynamic deployment by the data center application orchestration engine and operable in a user space of the host computing device. Processing circuitry is configured for execution of the containerized user-level applications and the cloud native virtual router. The cloud native virtual router comprises a containerized routing protocol process configured to operate as a control plane, and a data plane for the containerized router. The data plane is configured to operate an ethernet virtual private network (EVPN) encapsulation/decapsulation data path of an overlay network for communicating layer two (L2) network traffic of the containerized user applications over a switch fabric of the data center.

Abstract: Techniques are disclosed for maintaining processing unit core affinity for fragmented packets. In one example, a service physical interface card (PIC) implementing a service plane of a network device receives fragmented and/or non-fragmented packet data for a traffic flow. The service PIC comprises at least one processing unit comprising multiple cores. A routing engine operating in a control plane of the network device defines one or more core groups comprising a subset of the cores. The routing engine assigns the traffic flow to a core group and a forwarding engine operating in a forwarding plane of the network device forwards the packet data for the traffic flow to the assigned core group. A core of the assigned core group applies a network service to the fragmented and/or non-fragmented packet data for the traffic flow, and the forwarding engine forwards the packet data for the traffic flow toward a destination.

Abstract: An ingress network device may receive a core domain network segment identifier associated with a core domain network of the multi-domain network. The ingress network device may receive location data of an egress network device associated with a second leaf domain network of the multi-domain network, wherein the location data may include data identifying the core domain network segment identifier, a second leaf domain network segment identifier associated with the second leaf domain network, and an egress network device segment identifier associated with the egress network device. The ingress network device may store the core domain network segment identifier and the location data, and may utilize the core domain segment identifier and the location data to route traffic to the egress network device.

Abstract: A controller device receives, from a plurality of assisted replication network devices, respective utilization information associated with the plurality of assisted replication network devices. The controller device generates, based on the respective utilization information associated with the plurality of assisted replication network devices, load balancing information for a network device associated with two or more assisted replication network devices of the plurality of assisted replication network devices, and sends, to the network device, the load balancing information. The network selects, based on the load balancing information, a particular assisted replication network device of the two or more assisted replication network devices. The network device receives a traffic flow that is to be multicast and sends the traffic flow to the particular assisted replication network device, wherein sending the traffic flow to the particular assisted replication network device permits the particular assisted replication network device to multicast the traffic flow.

Abstract: An optical transmitter can generate probabilistically shaped quadrature amplitude modulation (PS-QAM) signaling for transmission over a fiber to a destination without optical amplification. The single fiber can transmit the PS-QAM signaling using dense wavelength division multiplexing having a relatively large number of channels that are closely spaced. A coherent receiver can receive the PS-QAM signaling for decoding without implementing chromatic dispersion compensation.

Abstract: Disclosed are embodiments for estimating risk associated with a user of a wireless device. In some embodiments, the risk relates to a risk of infection by a contagious disease. For example, in some embodiments, the contagious disease is Coronavirus 2019. In some embodiments, locations of multiple wireless devices are estimated based on signal strengths of signals associated with the devices. Neighboring devices are identified based on highest probability regions of the devices that are determined based on associated signals. A measure of proximity to other devices is then determined based on probabilities that each device is located in neighboring regions. The risk is then based on the measure of proximity. In some embodiments, a risk of a first user associated with a first wireless device is based, in part, on a risk of a second user within a proximity of the first user.
