When you think about Layer 2 of the OSI model, we need MAC address information to identify stations on the LAN. This information is "encapsulated" onto the data. At Layer 3 of the model, we need IP address information. This is "encapsulated" on the data.
So you see, the process of adding additional fields worth of information to the data is termed encapsulation. By the way, when a receiving machine strips this information of, that is called, de-encapsulation. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ahmed Haji Munye Sent: Thursday, August 18, 2011 12:06 AM To: CC IE Subject: [OSL | CCIE_RS] encapsulation data Hi Could you please explain in easy English what encasulating data is and what it does?
