ATM Reference Model

ATM Reference Model, defined by ITU-T, is a logical model to describe the ATM architecture and functionality that it supports. The ATM reference model is composed of the following planes, which span all layers: 1) Control—This plane is responsible for generating and managing signaling requests. 2) User—This plane is responsible for managing the transfer of data. 3) Management—This plane contains layer management and plane management components. The ATM reference model is composed of three ATM layers: physical layer, ATM Layer and ATM adaptation layer.
