Primarily the difference between UDP and TCP. Can’t tell you how many times I have had to explain a TCP port being open does not equal UDP, and vice versa.

Send UDP messages to a destination IP address and port number, listen for incoming UDP messages on a user-defined port, and echo received messages back to the source. Combine the sender and receiver into a single "UDP ping" application to test the communication channel between two network hosts, and illustrate the notifier method to stop
An adversary sends a UDP datagram to the remote host to determine if the host is alive. If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target.
Nmap “ping sweep” is a method to discover connected devices in a network using the nmap security scanner, for a device to be discovered we only need it to be turned on and connected to the network. ping packets is a type of ICMP packets.Is there any relation between ICMP with TCP.In other can we guaranty their arrival in the network I want to know ICMP packets in the network is tcp or udp or Specifying the "udp" protocol causes the ping() method to send a udp packet to the remote host's echo port. If the echoed packet is received from the remote host and the received packet contains the same data as the packet that was sent, the remote host is considered reachable. SRX300,SRX320,SRX340,SRX1500,vSRX. In this example, you configure both the host (device A) and the remote device (device B) to act as TCP and UDP servers. You configure a probe for customerC, which uses TCP packets. UDP Packets (Unix-Style). This uses ports 33434 – 33500 and closely mirrors Unix’s traceroute command. This uses ports 33434 – 33500 and closely mirrors Unix’s traceroute command. This method will sometimes allow you to trace to a destination that isn’t reachable via ICMP, or might allow you to reach the internet even if your ISP is
