Is ARP Connection oriented or connectionless? It uses TCP, but does that consider it connection oriented?

ARP Connection oriented or connectionless?

Connectionless - it's just a request and a response (or a broadcast just letting everyone know about something).

It uses TCP

It doesn't use TCP - TCP is a layer 4 protocol, whereas ARP is glue between layers 2 and 3.

  • In the same sense would the following be connectionless too: HTTP, SMTP, SNMP, POP3, Frame Relay? – Rick Dec 11 '14 at 21:06

    @Rick Not at all, you're comparing apples and squirrels - HTTP, SMTP and POP3 run on top of TCP, SNMP runs on top of UDP, and frame relay is for encapsulation of layer 2 traffic. – Shane Madden Dec 11 '14 at 21:14
