The largest telegram that can be transmitted without* fragmentation is 1500 bytes long. The network header requires fourteen* (14) of those bytes; therefore the largest amount of user data that can be* transmitted without fragmentation is 1486 bytes.  The sliding window* protocol's buffer has 32 entries, which results in a window of size 16.* The number of fragments that the packet can be broken into is limited by* the size of the sequence field in the network header.  The example* interface adapter can handle up to 10 fragments, which results in a* maximum packet length of 14860 ((1500 - 14) * 128) bytes.
