Home : Lectures : Lecture 13B : Internet Protocol (IP) & Datagrams Internet Protocol (IP) & Datagrams The IP layer communicates with packets called datagrams. Datagrams have headers of 20-60 bytes and data payloads of up to 65K bytes. Datagrams contain the basic IP source and destination addresses, e.g. 130.237.217.62. A few special nodes are Domain Name Servers that translate names like www.kth.se into the proper IP addresses. Datagrams may travel completely different paths as routers along the way dynamically choose paths for the same IP to avoid loading down any one link. So datagrams may be lost and/or arrive out of order from the order they were sent.
