摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In general, techniques are described for automatically and transparently providing service proxying to virtual machines using Network Interface Cards (NICs). In some examples, a service proxy implemented by a NIC of a computing device that hosts a virtual machine may mimic sidecar service proxy behavior. A NIC-based mesh agent may automatically detect the service offered by the virtual machine and interact with control plane components to dynamically incorporate the service into a service mesh.

摘要： In general, techniques are described for organizing execution of distributed operating systems for network devices. A device comprising hardware computing nodes may be configured to perform the techniques. The hardware computing nodes may execute a protocol by which to discover a topology of the plurality of hardware computing nodes, and determine, based on the topology, a subset of the plurality of hardware computing nodes to manage execution of a distributed operating system. The determined subset of the plurality of hardware computing nodes may execute a communication bus by which to synchronize operating system state information between the subset of the plurality of hardware computing nodes. The hardware computing nodes may further execute, based on the operating system state information, the distributed operating system to provide an execution environment in which one or more applications execute.

摘要： A system communicates, with a client device, to establish a first TLS communication session between the system and the client device, and with a server device, to establish a second TLS communication session between the system and the server device. The system generates a first session ticket associated with the first TLS communication session, and obtains, from the server device, a second session ticket associated with the second TLS communication session. The system sends, to the client device and via the first TLS communication session, the first session ticket, with the second session ticket included in the first session ticket. The system receives, from the client device and after the first TLS communication session and the second TLS communication session terminate, the first session ticket that includes the second session ticket, which the system uses to facilitate resumption of the first TLS communication session and the second TLS communication session.

摘要： Systems, devices and techniques for an adaptive application-specific probing scheme are disclosed. An example network device includes memory configured to store a network address and probe protocol usable for probing a first network device associated with a source of an application, and one or more processors configured to determine a network address and probe protocol usable for probing the first network device, wherein the first network device comprises a server that is responsive to the probing, the server executing the application for the data flow, or a closest network device, to the server, that is responsive to the probing. The one or more processors are also configured to send to a second network device at a location serviced by the application, a message specifying the network address and probe protocol usable for probing the first network device.
