Internet Protocol (IP) is a connectionless protocol that manages addressing data from one point to another, and fragments large amounts of data into smaller, transmittable packets. The major components of Internet Protocol datagrams are: IP Identification (IPID) Used to uniquely identify IP datagrams and for reassembly of fragmented packets.
If I understood well the initial IP payload should be fragmented in several smaller packets. Hence the first IP packet has the TCP/UDP header and probably the beginning of the UDP/TCP payload. The second one has the next part of the UDP/TCP payload, and so on until the whole UDP/TCP message is sent. Mar 26, 2012 · IP Header. Protocol Version(4 bits): This is the first field in the protocol header.This field occupies 4 bits. This signifies the current IP protocol version being used. Most common version of IP protocol being used is version 4 while version 6 is out in market and fast gaining populari May 13, 2020 · Identification is a 16 bit field used to identify each datagram. so that at destination if datagrams are received out of order then they can be reassembled in proper order. Fragmentation is done SRX Series,vSRX. Understanding IP Packet Fragment Protection, Example: Dropping Fragmented IP Packets, Understanding Bad IP Option Protection, Example: Blocking IP Packets with Incorrectly Formatted Options, Understanding Unknown Protocol Protection, Example: Dropping Packets Using an Unknown Protocol Running wireshark, one IP consistently has fragmented IP protocol. (proto=UDP) Going to a 239. address. How do you fix this? It is a video on demand server.
It appears to be fragmented. Then I decided to put the WLC, AP (in sniffer-mode) and the PC running Wireshark in the same layer 2, just to make sure my firewall did not fragment the packets, but my Wireshark still shows the packets as "IP Fragmented IP Protocol" UDP/17.
IP Routing, Format, Fragmentation Chapters 20-21, 23 IP • IP is connectionless in the end-to-end delivery – Data delivered in datagrams (packets / frames), each with a header • Combines collection of physical networks into single, virtual network • Transport protocols use this connectionless service to
