Next Page TCP/IP layers
- recall the 5-layer model above
- the network interface layer is often called the link layer
- we use the generic term packet for each block of data transmitted
- recall that each layer adds its own header, so nature of "packet" varies
- so in fact the following terms are usually used for "packets" at each layer
- frames at the link layer
- datagrams at the internet layer
- segments at the transport layer
- we focus on the transport layer in this section
