The minimum length is 8 bytes, the length of the header. The field size sets a theoretical limit of 65,535 bytes (8-byte header + 65,527 bytes of data) for a UDP datagram. However, the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 bytes − 8-byte UDP header − 20-byte IP header). [8]
A typical ROHC implementation will aim to get the terminal into Second-Order state, where a 1-byte ROHC header can be substituted for the 40-byte IPv4/UDP/RTP or the 60-byte IPv6/UDP/RTP (i.e. VoIP) header. In this state, the 8-bit ROHC header contains three fields: a 1-bit packet-type flag (set to '1' only for longer ROHC headers)
Static Context Header Compression (SCHC) is a standard compression and fragmentation mechanism defined in the IPv6 over LPWAN working group at the IETF. It offers compression and fragmentation of IPv6 / UDP / CoAP packets to allow their transmission over the Low-Power Wide-Area Networks (LPWAN) .
The Total Length field of IPv4 and the Payload Length field of IPv6 each have a size of 16 bits, thus allowing data of up to 65 535 octets. This theoretical limit for the Internet Protocol (IP) MTU, however, is reached only on networks that have a suitable link layer infrastructure. While IPv4 has no facilities to exceed its theoretical IP MTU ...
Data: Data is of variable length, limited by the maximum ICP message size (including header) of 16,384 octets. The ICP header consists of 8 fields, with 2 optional fields. The fifth and sixth field is optional (pink background in table) and appropriately named “options” and “option data”.
In computer networking, the Reliable User Datagram Protocol (RUDP) is a transport layer protocol designed at Bell Labs for the Plan 9 operating system.It aims to provide a solution where UDP is too primitive because guaranteed-order packet delivery is desirable, but TCP adds too much complexity/overhead.

The maximum segment size (MSS) is a parameter of the Options field of the TCP header that specifies the largest amount of data, specified in bytes, that a computer or communications device can receive in a single TCP segment. It does not count the TCP header or the IP header (unlike, for example, the MTU for IP datagrams).
