A method and wireless communication device use a first processing unit to perform a first communication event within a first communication window by use of a first communication protocol, a second processing unit to perform a second communication event within a second communication window by use of a second communication protocol, and a wireless communication unit connected to a radio-frequency antenna to transmit and/or receive a packet wirelessly. The first and second processing units may perform the first and second communication events via the wireless communication unit. The second processing unit or the wireless communication unit may transmit an event signal to the first processing unit when performing the second communication event or receiving a packet, respectively, to allow the first processing unit to arrange the first communication window (or first communication event) with respect to the second communication window (or second communication event) to minimize interference.

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.

A network device is configured to route an ingress packet based on its L2 header. In some configurations the ingress packet is routed based only on the destination MAC (DMAC) address in the L2 header, which allows the network device to begin routing as soon as the DMAC is received. The DMAC can be used in a table look up operation to identify routing actions for a nexthop. An egress packet is produced from the ingress packet using the routing actions. The egress packet is then sent on an egress port specified in the routing actions.

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.

A method for processing state information updates. The method includes receiving, by a coordination point, a plurality of state information from a plurality of network elements; processing at least one of the plurality of state information to generate a result; and applying the result to at least one of the plurality of network elements in order to modify an operation of the at least one of the plurality of network elements.

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.

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 method and wireless communication device use a first processing unit to perform a first communication event within a first communication window by use of a first communication protocol, a second processing unit to perform a second communication event within a second communication window by use of a second communication protocol, and a wireless communication unit connected to a radio-frequency antenna to transmit and/or receive a packet wirelessly. The first and second processing units may perform the first and second communication events via the wireless communication unit. The second processing unit or the wireless communication unit may transmit an event signal to the first processing unit when performing the second communication event or receiving a packet, respectively, to allow the first processing unit to arrange the first communication window (or first communication event) with respect to the second communication window (or second communication event) to minimize interference.
