Abstract: Systems, methods, and apparatus for serial bus arbitration are described. A method for managing transactions executed on a serial bus includes configuring a slave device coupled to the serial bus with information identifying a first number to be used to count data bytes, initiating a first transaction to transmit a block of data that has a second number of data bytes to the slave device, the second number being greater than the first number, and providing an opportunity for the slave device to acknowledge receipt of an immediately preceding first number of data bytes after an integer multiple of the first number of data bytes has been transmitted.

Abstract: Systems, methods, and apparatus for serial bus arbitration are described. A method for bus arbitration includes determining that at least one device coupled to a serial bus has been assigned a dynamic address with a non-zero most significant address bit, determining that all devices coupled to the serial bus have been assigned dynamic addresses that have a common zero-value address bit, initiating transmission of an arbitrable address header while a line driver coupled to a data line of the serial bus is configured for an open-drain mode of operation, and configuring the line driver coupled to the data line for a push-pull mode of operation when a bit in the arbitrable address header corresponding to the common zero-value address bit has a non-zero value on the data line. In one example, the serial bus may be operated in accordance with an I3C protocol.

Abstract: Methods, systems, and computer readable media for computing label-switched data communication paths are disclosed. An example method includes receiving, by a path computation element (PCE) implemented on at least one processor, synchronization status information for routing nodes in a label-switched network. The method includes receiving, by the PCE, a request for a label-switched path (LSP) from a client. The method includes determining, by the PCE, a responsive LSP based at least in part on the synchronization status information. The method includes sending, by the PCE, an explicit route object (ERO) for the responsive LSP to the client.

Abstract: Methods, systems, and computer readable media for advertising network security capabilities are disclosed. According to one method, the method occurs at a network node. The method includes receiving a first route advertisement message that includes network security capabilities information indicating capabilities of a network security system associated with a route. The method also includes receiving a packet associated with a packet flow. The method further includes directing the packet associated with the packet flow to a downstream network node associated with the network security system.
