Paper Summary:

This paper describes the Asynchronous Transfer Mode layers, which include the ATM Layer, AAL Convergence sub-layer, ATM Adaptation Layer or AAL, the AAL Model Segmentation and Reassembly sub-layer and the Higher Layer Protocols for control, management and application. The author points out that the ATM technology is a very detail oriented and maybe the most complex technology ever created in the current technologically driven society. The paper relates that the network-to network cell is used to define the interface between nodes throughout a network's switches or between two or more unique networks.

From the Paper:

"As noted, the ATM Cell utilizes a 5-byte header for the UNI and NNI cell formats. Although the fields of these formats are similar, there is an exception for the UNI cell format which includes a 4-bit generic flow control or GFC to assist in the overall flow control for the UNI level. The exception is based on the fact that the NNI level flow control is inadvertently created through longer VPI's which permits for more virtual paths, 12 bits vs. 8 bits for UNI. Other fields for the header are the VCI which consists of 16 bits, the payload type which consists of 3 bits, the cell loss priority which is 1 bit and the header error correction of 8 bits."
