Techniques are disclosed relating to handling queues. A server-based platform, in some embodiments, accesses queue information that includes performance attributes for a plurality of queues storing one or more messages corresponding to one or more applications. In some embodiments, the platform assigns, based on the performance attributes, a corresponding set of the plurality of queues to each of a plurality of processing nodes of the platform. In some embodiments, the assigning of a corresponding set of queues to a given one of the plurality of processing nodes causes instantiation of: a first set of one or more dequeuing threads and a second set of one or more processing threads. The dequeuing threads may be executable to dequeue one or more messages stored in the corresponding set of queues. The processing threads may be executable to perform one or more tasks specified in the dequeued one or more messages.

A device for avionics full-duplex switched Ethernet (AFDX) communication can include a transmit port for transmitting AFDX data and a processor. The processor can be configured to obtain AFDX data frames for transmission over a plurality of sub-virtual links (subVLs) of a virtual link (VL), and maintain, for each of the plurality of subVLs, a corresponding data queue by storing AFDX data frames associated with that subVL in the corresponding data queue. The processor can transmit the AFDX data frames from the plurality of data queues on the plurality subVLs via the transmit port according to a scheduling policy that is based on subVL prioritization. The scheduling policy that is based on subVL prioritization can include static priority (SPn) scheduling, earliest deadline first (EDF) scheduling, or least laxity first (LLF) scheduling.

A stateful network packet processing system includes first and second stateful stages and a distribution mechanism. The first stateful stage includes a first state table and a first FSM table. The second stateful stage includes a second state table and a second FSM table. The distribution mechanism defines when a flow should be processed by either the first stateful stage or the second stateful stage or by a combination of the first stateful stage and the second stateful stage. At least one of the first or second FSM tables is extended with states and transitions that support the distribution mechanism.

A system, method, and apparatus for detecting remote control of a client device are disclosed. An example network security apparatus includes a network switch configured to route first data packets between a client device and a content provider device, determine IP addresses of other devices that transmit second data packets to or receive second data packets from the client device, and throttle the second data packets destined for the client device. The apparatus also includes a controller configured to receive signal packets indicative of activity in relation to a webpage provided by the content provider device to the client device and instruct the network switch to throttle the second data packets after receiving one of the signal packets. The controller is also configured to provide an indication of a malicious device remotely controlling the client device responsive to not receiving another signal packet within a specified time period.

A PHY chip for a synchronous Ethernet system includes N network input/output (I/O) ports, a first external recovered clock input, a first recovered clock output, and a first clock multiplexer having a plurality of data inputs, a select input, and an output coupled to the first recovered clock output, at least one of the data inputs coupled to a first recovered clock from a respective one of the N network I/O ports, a first additional data input coupled to the first external recovered clock input.

The present subject matter relates to methods, systems, devices, circuitry and equipment providing for communication service to be transported between first and second networks, and which monitors the communication service and/or injects test signals, and which can provide redundancy. At least one demarcation point or line is established between the first network and the second network, and/or between the first network, the second network and/or a third network. The Circuitry comprises a plurality of input amplifiers, output amplifiers, and multiplexer switches between a plurality of Port connectors. An SFP module or a WSFP module is inserted in the Ports.

The concepts and technologies disclosed herein are directed to a network-assisted Raft consensus protocol, referred to herein as NetRaft. According to one aspect of the concepts and technologies disclosed herein, a system can include a plurality of servers operating in a server cluster, and a plurality of P4 switches corresponding to the plurality of servers. Each server of the plurality of servers can include a back-end that executes a complete Raft algorithm to perform leader election, log replication, and log commitment of a Raft consensus algorithm. Each P4 switch of the plurality of P4 switches can include a front-end that executes a partial Raft algorithm to perform the log replication and the log commitment of the Raft consensus algorithm. The back-end can maintain a complete state for responding to requests that cannot be fulfilled by the front-end. The requests can include read requests and/or write requests.

A Top of Rack (TOR) switch operating with a Software for Open Networking in the Cloud (SONiC) platform is implemented using commodity switch hardware and is configured to maintain or retrieve flow state information for incoming data flows in a load balancer. In one embodiment, an application-specific integrated circuit (ASIC) informs a user mode container flow state information for each incoming data flow. The user mode container informs the ASIC of any affected flows that may result pursuant to a modified distributed system (e.g., added, updated, or removed servers). In other embodiments, the ASIC may utilize remote direct memory access (RDMA) to retrieve flow state information maintained by a remote device or may utilize the RDMA to retrieve network address translation (NAT) information for incoming traffic. In each of the implementations, the integrity of the load balancing system is maintained when the distributed system of servers changes.

In one embodiment, a networking device in a network detects an traffic flow conveyed in the network via the networking device. The networking device generates flow data for the traffic flow. The networking device performs a classification of the traffic flow using the flow data as input to a machine learning-based classifier. The networking device performs a mediation action based on the classification of the traffic flow.
