Understanding ATM, MPOA, and ATM Router Redundancy Concepts

Cell Header
After dividing the data into 48-byte segments for transmission, the end device
--that is, the ATM data service unit/channel service unit (DSU/CSU) or native
ATM device--attaches the required header information (Figure 1-2
).
Figure 1-2. ATM Cell Header
The fields in each ATM cell header provide all the information necessary for
networking. These fields include the following:
• Generic flow control (GFC): The first 4 bits of the cell header contain the
GFC. The GFC controls traffic flow onto the ATM network by controlling the
user-to-network interface (UNI).
• Virtual path identifier (VPI): The next 8 bits of the cell header (that is, the last
half of byte 1 and the first half of byte 2) contain the VPI. The VPI specifies a
virtual path on the physical ATM link. See the next section, “Data
Transmission,” for additional information about virtual paths.
