Host device and slave device controlling method

摘要

A host device is provided, which includes a network communication unit connected to network; a local communication unit locally connected to a slave device; a virtualization unit to virtualize the slave device as a network device within the network; and a controlling unit to control the virtualized slave device as the network device. Therefore, a developer may implement an application in consideration of a single type of network without considering various physical input and output ports.

主权项

1. A host device, comprising:
a network communication interface to connect the host device to a network device on a network; a local communication interface to connect the host device to a slave device on a local network; a virtualizer comprising at least one processor to virtualize the slave device as a virtual network device within the network by allocating an Internet Protocol (IP) address to the slave device; a controller to control the slave device as the virtual network device; and a storage to store the IP address of the slave device, wherein the virtualizer allocates the IP address to the slave device by using a same IP address previously allocated to the slave device or by using a different IP address each time the slave device is connected to the host device.
