470 ICMP is not a part of transport
This tissue has following status: blue
Created: 13 Feb 2007
Paragraph: Table -4
Category: Issue for edition 2 of this part
Issue: In table-4, ICMP(RFC792) comes as a part of Transport layer protocol and just above TCP. But as per RFC792 & RFC791, ICMP is more likely to be treated as a network layer protocol.
Proposal: RFC792 should come just above RFC791 and both should be a part of network layer. RFC793 & RFC1006 should respectively come above the same as transport layer protocols.
