摘要： 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.
