Volume based attack includes ICMP floods and UDP floods and there are other floods also which are performed with the aid of spoofed packets
Protocol attacks is the attack which is performed on the level of protocol and the categories are Ping of death, synflood and there are many more.
Application layer attack targets Apache, Windows, open BSD and other vulnerabilities on the software to crash the entire server.
