networking - Is ICMP a transport layer protocol? -


i going through video lecture on networking , there lecturer mentions icmp transport layer protocol. however, googling shows various forums describing network layer protocol. has confused me lot. can clarify?

transport layer protocols concerned send data end-to-end , ensuring (or explicitly not ensuring) reliability. tcp used send data 1 computer , includes logic necessary ensure data transported correctly, while udp used send data 1 computer while getting reliability.

icmp doesn't this. job routers figure out shape of internet , direction send packets different protocols. consequently, it's considered network-layer protocol, since job ensure data routed right place doesn't route data.

hope helps!
