A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies. [2]
Low Orbit Ion Cannon (LOIC) is an open-source network stress testing and denial-of-service attack application written in C#.LOIC was initially developed by Praetox Technologies, however it was later released into the public domain [2] and is currently available on several open-source platforms.
When a ping of death is initiated, it is my understanding that the command used, i.e. "ping -l 65536" will cause an oversized ping packet to be sent to the host by inserting 65536 bytes into the ICMP data field. As the ping is sending, then ICMP makes an ICMP_ECHO_REQUEST and this ICMP_ECHO_REQUEST is 65536 bytes.
The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay , which depends on the load on the responding node.
In actuality, a 64 kilobyte file is 64 × 1,024 × 8 bits in size and the 64 k circuit will transmit bits at a rate of 64 × 1,000 bit/s, so the amount of time taken to transmit a 64 kilobyte file over the 64 k circuit will be at least (64 × 1,024 × 8)/(64 × 1,000) seconds, which works out to be 8.192 seconds.

An effective throughput of 2.27 Mbit/s was achieved. The purpose of the test was to measure and confirm an improvement over RFC 2549. [ 8 ] Since the developers used flash memory instead of paper notes as specified by RFC 2549, the experiment was widely criticized as an example in which an optimized implementation breaks an official standard.
