A method for optimizing internet traffic from a plurality of local area networks (LANs) to an internet based server connected to internet includes instructions for analyzing an internet data by a gateway computer located in a first LAN of the plurality of LANs to determine a data that is latency sensitive and a data that is not latency sensitive; instructions for sending network steering data, by the gateway computer, to a Central Processing Matrix (CPM); instructions for sending data, by a plurality of customer premises equipment (CPE) located in a second plurality of LANs in the plurality of LANs to the CPM through a listener/reporter located outside of the plurality of LANs; instructions for receiving the network steering data by the listener/reporter from the CPM; and instructions for routing the data that is latency sensitive outside of the second plurality of LANs to the internet based server.

A network function virtualization service includes an action implementation layer and an action decisions layer. On a flow of network traffic received at the service, the action implementation layer performs a packet processing action determined at the action decisions layer.

A Storage Area Network (SAN) access includes a first aggregated switch device that is coupled to a host device, a Local Area Network (LAN), and a SAN, and a second aggregated switch device that is coupled to the host device, the LAN, and the SAN. The second aggregated switch device is connected to the first aggregated switch device via an Inter-Chassis Link (ICL). The second aggregated switch device detect that the ICL has become unavailable and, in response, prevents Internet Protocol traffic between the host device and the LAN while transmitting storage traffic between the host device and the SAN.

Methods and apparatus for smart switch centered next generation cloud infrastructure architectures. Smart server switches are implemented in place of Top of Rack (ToR) switches and other switches in cloud infrastructure that include programmable switch chips (e.g., P4 switch chips) that are programmed via data plane runtime code executing on the switch chips to implement data plane operations in hardware in the switches. Meanwhile, control plane operations are implemented in the server switches via software executing on one or more CPUs or are implemented via servers that are coupled to the server switches. The data plane runtime code is used to forward data traffic and storage traffic in hardware via the programmable switch chips in a manner that offloads forwarding to hardware in virtualized cloud environments.

Provided is a collision prevention system of a multi-master including: a plurality of external modules; and an integrated device. The integrated device includes: a plurality of interfaces connected respectively to the plurality of external modules and respectively controlled by corresponding external modules; a plurality of internal modules; a plurality of dedicated buffers connected respectively to the plurality of interfaces and the plurality of internal modules; and a common block connected to the plurality of dedicated buffers and controlled by the plurality of interfaces and the plurality of internal modules. The plurality of dedicated buffers includes a GBU and a plurality of LBUs. The GBU and the plurality of LBUs are connected to two neighboring GBUs and a plurality of LBUs to form a ring communication topology, which transmits ring communication data in one direction. The common block is connected to the ring communication topology through the GBU.

According to one or more embodiments of the disclosure, a supervisory networking device in an Ethernet ring obtains identity information for each of a plurality of other networking devices in the Ethernet ring. The supervisory networking device determines, based on the identity information, a relative position for each of the plurality of other networking devices in the Ethernet ring. The supervisory networking device generates, based on the relative position of each of the plurality of other networking devices in the Ethernet ring, a load balancing configuration for the Ethernet ring. The supervisory networking device implements the load balancing configuration in the Ethernet ring by blocking a first link of the supervisory networking device for a first subset of the plurality of other networking devices and a second link of the supervisory networking device for a second subset of the plurality of other networking devices.

A web handling system is described, including a plurality of web handling controllers and a web handling process logic controller networked to form a ring network. A processor of the web handling process logic controller being configured to determine whether a fault exists within the ring network, and responsive to determining that a fault exists within the ring network, to generate and send signals throughout the ring network to switch the configuration of the ring network to at least one linear network.

At this time, a communication line load transmission interval deciding unit selects a transmission interval from the load of the bus. An instrument load transmission interval deciding unit selects a transmission interval from the processing loads of at least one of the vehicle on-board instrument and the gateway. A delivery control unit compares the transmission interval selected by the communication line load transmission interval deciding unit with the transmission interval selected by the instrument load transmission interval deciding unit, and performs control so that the divided updating data is delivered at transmission intervals which are equal to or greater than the longer of these transmission intervals.

A network device includes a Network Interface Device (NID) and multiple servers. Each server is coupled to the NID via a corresponding PCIe bus. The NID has a network port through which it receives packets. The packets are destined for one of the servers. The NID detects a PCIe congestion condition regarding the PCIe bus to the server. Rather than transferring the packet across the bus, the NID buffers the packet and places a pointer to the packet in an overflow queue. If the level of bus congestion is high, the NID sets the packet's ECN-CE bit. When PCIe bus congestion subsides, the packet passes to the server. The server responds by returning an ACK whose ECE bit is set. The originating TCP endpoint in turn reduces the rate at which it sends data to the destination server, thereby reducing congestion at the PCIe bus interface within the network device.

A packet communication method that generates a header that includes information to route a packet through a ring communication network is described. The header can include a target node identifier that identifies a target node to which the packet is to travel, and a direction identifier that identifies a direction to be traversed by the packet through the ring communication network. In some embodiments, the direction indicated by the direction identifier can be clockwise or counter-clockwise relative to a starting node from which the packet is to travel.
