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.

Systems, methods, apparatus and computer-readable medium are described for improving efficiency and robustness for sharing data across different users, agents, processes, drivers, and applications in a system. A shared buffer between multiple entities may be used for sharing data such that the data is only stored once and accessed by multiple entities without copying the data over and over again. An example system may be a network device. For a received packet at a network interface of a network device, the packet may be stored directly in memory. The application or process responsible for accessing and/or manipulating the packet can directly do so by simply using a buffer pointer provided by the buffer manager.

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.
