An apparatus for switching network traffic includes an ingress packet forwarding engine and an egress packet forwarding engine. The ingress packet forwarding engine is configured to determine, in response to receiving a network packet, an egress packet forwarding engine for outputting the network packet and enqueue the network packet in a virtual output queue. The egress packet forwarding engine is configured to output, in response to a first scheduling event and to the ingress packet forwarding engine, information indicating the network packet in the virtual output queue and that the network packet is to be enqueued at an output queue for an output port of the egress packet forwarding engine. The ingress packet forwarding engine is further configured to dequeue, in response to receiving the information, the network packet from the virtual output queue and enqueue the network packet to the output queue.

Techniques for non-disruptive configuration changes are provided. A packet is received at a network device, and the packet is buffered in a common pool shared by a first processing pipeline and a second processing pipeline, where the first processing pipeline corresponds to a first policy and the second processing pipeline corresponds to a second policy. A first copy of a packet descriptor for the packet is queued in a first scheduler based on processing the first copy of the packet descriptor with the first processing pipeline. A second copy of the packet descriptor is queued in a second scheduler associated based on processing the second copy of the packet descriptor with the second processing pipeline. Upon determining that the first policy is currently active on the network device, the first copy of the packet descriptor is dequeued from the first scheduler.

An integrated circuit (IC) device includes a network device. The network device includes first and second network ports each configured to connect to a network, and an internal endpoint port configured to connect to first endpoint having a first processing unit and second endpoint having a second processing unit. A lookup circuit is configured to provide a first forwarding decision for a first frame to be forwarded to the first endpoint. An endpoint extension circuit is configured to determine a first memory channel based on the first forwarding decision for forwarding the first frame, and forward the first frame to the first endpoint using the determined memory channel.

Examples described herein relate to a network interface device comprising circuitry to: allocate a first number of buffers to store received packets associated with a first descriptor ring; allocate a second number of buffers to store received packets associated with a second descriptor ring; and based on receipt of a packet, copy the received packet into a number of buffers based on whether the received packet is associated with the first descriptor ring or the second descriptor ring. In some examples, the circuitry is to copy the received packet starting at an offset from a start of a starting buffer in a number of buffers, wherein the offset is based on whether the received packet is associated with the first descriptor ring or the second descriptor ring and wherein the number of buffers is based on whether the received packet is associated with the first descriptor ring or the second descriptor ring.

A communication apparatus comprises a rollback control unit to create a second process to roll back a currently working first process thereto; a storage to store states shared by the first and the second processes, the second process taking over a state(s) stored in the storage unit; a buffer; and a timing control unit that controls of timing of rollback. The rollback control unit starts event buffering to store in the buffer all of an event(s) received during when the first process is processing and destined to the first process, and upon completion of the processing of the event by the first process, the rollback control unit performs switching of a working process from the first process to the second process, sends the event(s) stored therein from start of the event buffering to the second process and stop event buffering.

A packet filtering system uses linked zero-based binary search trees to filter received packets. The binary search trees may be generated from filter conditions defining filter parameters for filtering packets.

A method for data transmission may be implemented on an electronic device having one or more processors. The one or more processors may include a master queue including a master queue head and a plurality of primary ports that are connected to each other using a serial link. The method may include operating the master queue head to obtain a message. The method may also include operating the master queue head to segment the message into a plurality of segments. The method may also include operating the master queue head to transmit the plurality of segments to a first primary port of the plurality of primary ports in the master queue. The method may also include operating the first primary port to transmit the plurality of segments to a second primary port of the plurality of primary ports in the master queue.

A method, computer program product, and a computing system are provided for de-duplicating remote procedure calls at a client. In an implementation, the method may include generating a plurality of local pending remote procedure calls. The method may also include identifying a set of duplicate remote procedure calls among the plurality of remote procedure calls. The method may also include associating each remote procedure call within the set of duplicate remote procedure calls with one another. The method may also include executing a remote procedure call of the set of duplicate remote procedure calls. The method may further include providing a response for the remote procedure call of the set of duplicate remote procedure calls with the other remote procedure calls of the set of duplicate remote procedure calls.

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.

Technologies for enforcing coherence ordering in consumer polling interactions include a network interface controller (NIC) of a target computing device which is configured to receive a network packet, write the payload of the network packet to a data storage device of the target computing device, and obtain, subsequent to having transmitted a last write request to write the payload to the data storage device, ownership of a flag cache line of a cache of the target computing device. The NIC is additionally configured to receive a snoop request from a processor of the target computing device, identify whether the received snoop request corresponds to a read flag snoop request associated with an active request being processed by the NIC, and hold the received snoop request for delayed return in response to having identified the received snoop request as the read flag snoop request.
