Because of the options, TCP header lengths vary. Thus, TCP needs the header length field to allow the receiver to separate the end of the header from the data. UDP has no options, no need for a length field, and no need to pad the options field out to a multiple of 32 bits in size. TCP supports flow control, but UDP does not.
What is the minimum UDP header size? 8 bytes. Put the steps in the most correct order for closing a TCP Connection. Client sends segment with FIN bit set The minimum frame size for IPv4 is 64 bytes, where the Ethernet header takes up 18 bytes, the IPv4 header 20 bytes, and the UDP header 8 bytes. The remaining 18 bytes are payload, where Netrounds places a sequence number, a timestamp, a checksum, and a stream ID. Both protocols use different types of header to pack the data for transmission. UDP header contains information only about the compulsory functions and it is 8 bytes in the length. TCP header contains information for both compulsory and optional functions. TCP header is 20 bytes and 24 bytes in length without options and with options respectively. ip.addr==192.168.10.1 and udp.port==47555 and (udp contains "k") and udp.length==4 But it doesn't seem to work. The Length column gives me 60, while the Info columns tells be that Len=4. From what I understand the first is what is returned by frame.len and represents the size of the whole frame while the second is limited only to the size of
See User Datagram Protocol. The UDP Header is 8 Bytes (64 bits) long. The mimimum size of the bare TCP header is 5 words (32bit word), while the maximum size of a TCP header is 15 words. Best wishes, Fabian

Aug 28, 1980 · The pseudo header conceptually prefixed to the UDP header contains the source address, the destination address, the protocol, and the UDP length. This information gives protection against misrouted datagrams. This checksum procedure is the same as is used in TCP.
