Thus, when the host number becomes large, the ARP traffic becomes prohibitively high. The amount of broadcast traffic roughly increases linearly with the number of hosts. For example, in a network with about a few thousand hosts, studies have shown that a host can receive a thousand ARP request per second. Previous researches have pointed out that broadcast traffic causes issues like scalability and security. Accordingly, a broadcast packet usually consumes much more resources than a unicast packet. Broadcast traffic is sent to all hosts within a broadcast domain. Examples of such protocols include the address resolution protocol (ARP) and dynamic host configuration protocol (DHCP). Some protocols utilize broadcast to perform their functionalities. Patent Publication 2017/0126615, is incorporated herein by reference. Provisional Patent Application 62/250,487.
