packet-filtering
b. Payload that's what the data in a packet is called. The other parts are "header" and "trailer" depending on if they are at the beginning or end of the packet
That is called an IP address.
ATM use cell switching. it use a 52 by long packet where 48 byte is data and 4 byte is header.
Data is transmitted on a network in pieces called packets, datagrams, or frames. Specifically, the frame is the header and trailer surrounding the data. The entire header, trailer, and data is called the packet or datagram. A token is a small packet used on Token Ring or FDDI networks. The token is passed from node to node to indicate to the node that data can be sent on the network.
The header of an IP packet does not include fields required for reliable data delivery. There are no acknowledgments of packet delivery. There is no error control for data.

ip packet header
ip packet header
Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet. ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead
header, packet(data), and trailer
See time-to-live (TTL) packet
An IP packet can contain data about the format of the internet header and the abstract parameters such as the header checksum. The IP packets also provide an internet time stamp.

the answer is a Header,the a Payload, then last is the Trailer
That is the way the standard designed the header. They could be placed anywhere as long as everyone understood where in the packet header it was placed.
