WebFor TCP, application layer messages are reassembled through analysis of acknowledgement numbers between segments. For UDP, each datagram payload is interpreted as an application layer message. As of now, pcap-reassembler is compatible with Ethernet as link layer protocol, IPv4 as network layer protocol, and TCP or UDP as transport layer protocols. WebIP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.
