A first forwarding VM may execute in a first availability zone and have a first IP address. Similarly, a second forwarding VM may execute in a second availability zone and have a second IP address. The first and second IP addresses may be recorded with a cloud DNS web service of a cloud provider such that both receive requests from applications directed to a particular DNS name acting as a single endpoint. A service cluster may include a master VM node and a standby VM node. An IPtable in each forwarding VM may forward a request having a port value to a cluster port value associated with the master VM node. Upon a failure of the master VM node, the current standby VM node may be promoted to execute in master mode and the IPtables may be updated to now forward requests having the port value to a cluster port value associated with the newly promoted master VM node (which was previously the standby VM node).

Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized content fabric. In some implementations, one or more processors are configured to provide fabric nodes of an overlay network, including one or more fabric nodes that receive a client’s request to access digital content on the overlay network. The request includes an authorization token digitally signed by or on behalf of a user of the client. The fabric node(s) extract a user identifier (ID) from the authorization token, then determine that one or more rules maintained on the overlay network are satisfied. The one or more rules condition access to the digital content upon the extracted user ID matching an ID associated with an owner of a digital instrument. The digital instrument, which can be a non-fungible token, is stored in a blockchain ledger as a unique representation of the digital content.

A packet processing technique can include receiving a packet, and parsing the packet based on a protocol field to generate a parse result vector. The parse result vector is used to select between forwarding the packet to a virtual machine executing on a host processing integrated circuit, forwarding the packet to a physical media access controller, multicasting the packet to multiple virtual machines executing on the host processing integrated circuit, and sending the packet to a hypervisor.

An avionics data network includes a network switch core configured for a time-sensitive networking (TSN) schema, a first and second set of networking end nodes communicatively coupled with the network switch core. The first set of networking end nodes includes a first subset of networking end nodes configured for a TSN schema and second subset of networking end nodes configured for a legacy Ethernet schema. The network switch core is configured to receive, from the first set of networking end nodes, a set of data frames, determine the respective schema of the set of data frames, forward the set of data frames to a predetermined queue on an egress port based on the determined respective schema, and transmit set of data frames to an end node having a corresponding schema.

Systems, methods, and computer-readable media are presented herein for providing lower level physical-layer gateway functionalities and upper-level application functionalities; a system designed with flexible configurations in order to support a wide range of connected applications. The system can include a processor that executes machine instructions to perform operations. The operations can comprise: receiving, from a first device, a first packet representing first data formatted in a first protocol language; transforming the first data to second data formatted in a second protocol language; and transmitting a second packet representing the second data to a second device.

Embodiments of this application disclose a collective communication method, apparatus, and system. The method includes: A first network device receives a first packet; the first network device receives at least one second packet; and the first network device sends a third packet based on the first packet and the at least one second packet. When no connection is established between the first network device and a terminal device, the first network device may aggregate and distribute collective communication packets by using a connection between the first terminal device and another terminal device.

A packet processing technique can include selecting a protocol field from the packet, and performing a comparison of the selected protocol field with comparison data in a compare logic array to output a protocol index. The protocol index can be used as an address to read parsing commands from a parse control table, and a parse result can be generated based on executing the parsing commands on the packet. The parse results are used to derive a parse result vector, which can be used by a forwarding engine to forward the packet.

An apparatus and method for path creation element driven dynamic setup of forwarding adjacencies and explicit path. In one embodiment of the method, a node receives an instruction to create a tunnel between the node and another node. The node creates or initiates the creation of the tunnel in response to receiving the instruction, wherein the tunnel comprises a plurality of nodes in data communication between the node and the other node. The node maps a first identifier (ID) to information relating to the tunnel. The node advertises the first ID to other nodes in a network of nodes.

Data is received at a buffer used by a protocol processing stack which protocol processes the received data. The received data is made available to, for example, an application, before the protocol processing of the data is complete. If the protocol processing is successful, the data made available to the application is committed.

A switching device relays data in an on-vehicle network and has a plurality of communication ports. The switching device comprises: a detection unit that detects a failure in communication with another switching device connected to one of the communication ports; and a processing unit that transmits failure information indicating at least any one of a site where the failure in communication occurs and a communication port to be used when the failure in communication occurs by a target switching device being a switching device different from said another switching device, to the target switching device if the failure in communication is detected by the detection unit.
