Abstract: Port parameters corresponding to a port of a network switching unit are received at one or more processing chips in the network switching unit. Both (i) serializer/deserializer (SerDes) parameters corresponding to the port, and (ii) transceiver parameters corresponding to the port, are obtained from a local storage based on the port parameters by the one or more processing chips. Signal processing operations of a SerDes unit are configured by the one or more processing chips using the SerDes parameters. The transceiver parameters are provided to a local platform of the network switching unit, for configuration, using the transceiver parameters, of a transceiver communicatively coupled to the port. The signal processing operations are performed by the SerDes unit, according to the SerDes parameters, on a signal received at the SerDes unit from the transceiver or on a signal transmitted from the SerDes unit to the transceiver.

Abstract: Systems, methods, apparatus, and a computer-readable medium are described for generating and receiving information regarding the current state of the active virtual machine in the host and switching the standby virtual machine from standby to active in response to determining that the current active virtual machine may no longer be able to service network packets.

Abstract: Provided are systems, methods, and computer-readable medium for enabling sharing of a multi-channel packet processor by multiple processes executing on a network device. The network device can include a memory management unit, configured to include an address map. The address map can include a reserved portion. The virtual machine can allocate a guest portion in the address map, where the guest portion is allocated in a part of the address map that does not include the reserved portion. A first channel from the packet processor can be assigned to the guest portion, and the virtual machine can use the first channel to receive packets. The reserved portion can be assigned to a host process executing on the network device. A second channel from the packet processor can be assigned to the reserved portion. The host process can transmit packets to the network using the second channel.

Abstract: Systems, methods, apparatus, and computer-readable medium are described for executing a foreground bound process with characteristics similar to a background process. In certain implementations, a code wrapper is executed before and/or after the foreground bound process is invoked that dissociates the process input/output with the standard input/output provided by the operating system and redirects the input/output such that the foreground process no longer blocks the input/output and another process can interact with the foreground bound process.
