In reality, the information that the user sees is routed through the layers represented in the following models. Each layer modifies the information a user is either sending or receiving, according to the standards or protocol established for each individual layer. BRIM-A6 User’s Guide Page B-5... - Page 44 All of the upper layers (that is, Transport and higher) generally follow the same rules. The bottom three layers of the ATM model, however, replace the bottom three layers of the OSI model.
