Ipv4 datagram and encapsulation
Did you know?
WebThis is exactly what the IP datagram is and this process is known as encapsulation. The entire contents of an IP datagram are encapsulated as the payload of an ethernet frame. You might have picked up on the fact that our IP datagram also has a payload section. The contents of this payload are the entirety of a TCP or UDP packet. WebLayer 3 - IPv4 datagram Protocol = 6 means data portion contains a TCP segment. Protocol = 17 means UDP. Version = 4 If no options, IHL = 5 Source and Destination are 32-bit IPv4 addresses Version IHL Diff Services Total Length Identification Flags Fragment Offset Time to Live Protocol Header Checksum Source Address (32-bit IPv4 address)
http://www.tcpipguide.com/free/t_IPDatagramEncapsulationandFormatting.htm WebFragmentation and Reassembly Using an encapsulation (IPv4-in-IPv6 or anything else) to carry IPv4 traffic over IPv6 will reduce the effective MTU of the datagram. Unfortunately, path MTU discovery [ RFC1191] is not a reliable method to deal with this problem.
