Protocol Development under Layered Architecture (PDLA)

 

The need to communicate with each other has become an important criterion for everyone of us, irrespective of life styles and individual preferences. Gone are the days of slow Postal Letter Systems as Communication now happens with Computers working at super high speeds with superlative efficiency. Concentrated developments have taken place for a few decades now, leading to “Models” providing a near perfect solution. “Networking” is the buzzword when computers and Network Enabled Devices communicate. Network is also meant for a layman and facilitates sharing of resources. While using is a pleasure, understanding the way the network works, its functionality and its internals, is very much a professionally desired skill. It is an entirely specialized subject but sometimes unreachable.

 

A network consists of many rules and regulations, called Protocols. International Standards Organization (ISO) proposed Open Systems Interconnection (OSI) Model, a 7-layered architecture to inter-network computers. To fulfill the many desired skills, a new concept called Protocol Development under Layered Architecture (PDLA) is introduced. It is a concept that will simplify and bring the complexities of the Network, Protocols, and Protocol Development with a methodology that is unique and interesting, preserving all the important concepts required for the network.

Text Box: Need of the System Management of the Network consists of undergoing courses meant for System Administration, where in the art of managing a network is learnt. But Protocol Development is altogether a different issue and involves a much higher technical skill and delves into the subject much more in depth. The architecture of the network is the ISO's Open System Interconnection Model (OSI Model). The OSI Model is a reference model only and the practical implementations are based on it.   PDLA works at the bottom four layers of the OSI Model. It is based on the protocols at these layers forming the core part of the system. These concepts and protocols are used by many of the higher layer based Protocols.
