Systems and methods of detecting and assigning IP addresses to devices with ARP requests

摘要

A method of discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes includes continuously monitoring, by the device to be discovered, the network for address resolution protocol (ARP) requests. The discoverer node transmits a number of ARP request to the network. The device to be discovered receives the number of ARP requests. The device to be discovered determines whether the number of ARP requests are unanswered by other devices in the network. The device to be discovered answers to the number of ARP requests with an ARP reply to claim an IP address associated with the number of ARP requests. The discoverer node and the device to be discovered exchange a pair of User Datagram Protocol (UDP) packets to complete the detection process.

1. A method of discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes, the method comprising:
selecting, by a discoverer node, a first IP address for the assigning to the device to be discovered; continuously monitoring, by the device to be discovered, the network for address resolution protocol (ARP) requests; transmitting, by the discoverer node to the network, a plurality of ARP requests associated with the selected first IP address; receiving, by the device to be discovered, the plurality of ARP requests; determining, by the device to be discovered, whether the plurality of ARP requests are unanswered by other devices in the network; answering, by the device to be discovered, the plurality of ARP Requests with an ARP reply to claim the selected first IP address associated with the plurality of ARP Requests; and exchanging a pair of User Datagram Protocol (UDP) packets between the discoverer node and the device to be discovered.
