A multi-fabric VLAN configuration system includes a first fabric with server devices that are configured to communicate using VLANs, a primary I/O module coupled to the server devices, and a first fabric management system coupled to the server devices and the primary I/O module. The first fabric management system identifies VLAN information associated with the VLANs, automatically configures the primary I/O module using the VLAN information, and causes the VLAN information to be transmitted by the primary I/O module. A second fabric in the multi-fabric VLAN configuration system includes a leaf switch device that is coupled to the primary I/O module and that receives the VLAN information, and a second fabric management system that is coupled to the leaf switch device and that receives the VLAN information from the leaf switch device, and automatically configures the leaf switch device using the VLAN information.

A ring interconnect system comprises a plurality of nodes. Each node is connected to two other nodes to form a ring interconnect. Every pair of nodes is connected by an inter-node path for that pair of nodes distinct from the ring interconnect. Each of the nodes comprises a message buffer to buffer messages received from at least one device associated with the node. Each of the nodes also comprises activity level circuitry to transmit an activity indication, when a number of the messages in the message buffer is equal to or above a threshold, to each other node of the plurality of nodes via the respective inter-node paths. Each of the nodes also comprises arbitrator circuitry to receive the activity indications from each other node and from the activity level circuitry, and to allow ingress of a message from the message buffer onto the ring interconnect in dependence on the activity indications. Also provided is a method of operating a node of a ring interconnect system.

A processing device has a plurality of interfaces and a plurality of processors. During different phases of execution of a computer program, different processors are associated with different interfaces, such that the connectivity between processors and interfaces for the sending of egress data and the receiving of ingress data may change during execution of that computer program. The change in this connectivity is directed by the compiled code running on the processors. The compiled code selects which buses associated with which interfaces, given processors are to connect to for receipt of ingress data. Furthermore, the compiled code causes control messages to be sent to circuitry associated with the interfaces, so as to control which buses associated with which processors, given interfaces are to connect to.

Systems, methods, and computer-readable media are disclosed for an apparatus coupled to a communication bus, where the apparatus includes a queue and a controller to manage operations of the queue. The queue includes a first space to store a first information for a first traffic type, with a first flow class, and for a first virtual channel of communication between a first communicating entity and a second communicating entity. The queue further includes a second space to store a second information for a second traffic type, with a second flow class, and for a second virtual channel of communication between a third communicating entity and a fourth communicating entity. The first traffic type is different from the second traffic type, the first flow class is different from the second flow class, or the first virtual channel is different from the second virtual channel. Other embodiments may be described and/or claimed.

The disclosed systems and methods provide hyperscalar packet processing. A method includes receiving a plurality of network packets from a plurality of data paths. The method also includes arbitrating, based at least in part on an arbitration policy, the plurality of network packets to a plurality of packet processing blocks comprising one or more full processing blocks and one or more limited processing blocks. The method also includes processing, in parallel, the plurality of network packets via the plurality of packet processing blocks, wherein each of the one or more full processing blocks processes a first quantity of network packets during a clock cycle, and wherein each of the one or more limited processing blocks processes a second quantity of network packets during the clock cycle that is greater than the first quantity of network packets. The method also includes sending the processed network packets through data buses.

A method for traffic management of proprietary data, in a network system comprising a gateway and a sensor communicatively coupled to the gateway via a data bus, includes determining, by a processor of a bridging device, whether a dedicated pipeline for transmission to the gateway is available, in response to determining that the dedicated pipeline is available, transmitting, by the processor, a request for the dedicated pipeline, determining, by the processor, whether the dedicated pipeline has been established between the bridging device and the gateway, and in response to determining that the dedicated pipe has been established, requesting, by the processor, the proprietary data from the sensor, transmitting, by the processor, the proprietary data from the sensor to the gateway via the dedicated pipeline, and transmitting, by the processor, a dedicated pipeline release signal to the gateway indicating release of dedicated pipeline between the bridging device and the gateway.

A method and device for packet processing implemented by a packet processing device is described. The packet processing device is connected to a communication network from which the packet processing device receives and/or transmits packets in a context of network service chaining.

In accordance with implementations of the subject matter described herein, there is provided a solution for streaming communication between devices. In this solution, a memory of a first device comprising a ring buffer is allocated to be dedicated for storing a data stream of an application to be transmitted to a second electronic device. The application of the first device writes data to be transmitted into the ring buffer, to form a portion of the first data stream, and a write pointer of the ring buffer is thus updated. A portion of data is read based on a source memory address from the ring buffer via the interface device. The interface device also transmits the data portion to a second device. The read data portion is stored in a dedicated ring buffer of the memory. In accordance with the solution, an efficient streaming communication interface is provided between devices.
