Reverse Routing Header

Reverse Routing Header (RRH): RRH [7] uses source routing techniques to route packets on the best path of the nested mobile network while sending packets from the MNN to the CN. A mobile router (MR) connected to the MNN assigns "n" RRHs to the previous mobile router (MR) and the tunnel header. The last mobile router (MR) inserts its home address into the slot, the destination address of the external IPv6 header is the HA of the last mobile router (MR), and the source address is the care-of address of the last MR.

The source address is the address in the IPv6 header. The destination address is the final destination, if the IPv6 packet does not contain a routing header it will be the destination address of the IPv6 header, otherwise it will be the address of the last element of the routing header on the source node and will be received. On the node, it becomes the destination address of the IPv6 header. The value of the Next Header field is the protocol value of UDP: 17. The UDP length field is the length of the UDP header and data.

TCP / IP is a two-part system that functions as the basic "control system" of the Internet. IP stands for Internet Protocol, its role is to send and route packets to other computers using the IP header (ie IP address) of each packet. The second part, the Transmission Control Protocol (TCP), decomposes the message or file into smaller packets, routes the packet to the correct application on the target computer using the TCP header, and if the packet is lost in the middle I will resend it. Once the packet arrives at the other end, the packet is reassembled in the correct order.

A packet is a finite sequence of bits divided into a control header portion and a data portion. The header contains enough information to route the packet to its destination. A check is usually performed on each such packet so that the switch (or interface) through which the packet passes can be error-controlled. Packets are usually associated with the operation of the internal packet network and are not necessarily visible from hosts connected to the network. Finite length packets can be completely exchanged between hosts, with destination host address information (usually source address), regardless of all other datagrams sent over the packet switched network. Typically, the maximum length of a datagram is 1000 to 8000 bits.
