The benefits of using a layered model
Assisting in protocol design because protocols that operate at a specific layer have defined
information that they act upon and a defined interface to the layers above and below
Fostering competition because products from different vendors can work together
Preventing technology or capability changes in one layer from affecting other layers above and
below
Providing a common language to describe networking functions and capabilities
Protocol model this type of model closely matches the structure of a particular protocol suite
Reference model this type of model provides consistency within all types of networking protocols and
services by describing what to be done at a particular layer
Segmentation breaking communication into pieces
Multiplexing multiple communications are interleaved, giving each user a part of the bandwidth
