However it must be noted that this model only represents a general guideline for developing usable network interfaces and protocols. Sometimes it may become very difficult to distinguish between each layer as some systems do not rigorously adhere to the model. Despite all this, however the OSI model has earned the honour of being "the model" upon which all good network protocols are based.
