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.

The lightweight UDP protocol shim does not admit much in the way of additional functionality, and one possible approach is to insist that UDP-based applications limit themselves to the local MTU size or, to be even more conservative, limit themselves to the 1,280 octet IPv6 minimum unfragmented packet size.

WebUDP can be used in applications that require lossless data transmission. For example, an application that is configured to manage the process of retransmitting lost packets and correctly arrange received packets might use UDP. This approach can help to improve the data transfer rate of large files compared to TCP.
