The below network diagram shows the telecommunication network architecture. It should be noted here that network architecture is a layout that provides a framework for drawing a network communication plan, network floor plan layout, LAN and WAN Diagram, and Cisco Network diagram. As shown below, an abstract generic system model and methodology that form the Telecommunications Network Architecture (TNA) are described. The below model represents controls and communication functions required to transfer information within a node or a network of nodes providing any service (message, packet, or voice). Use EdrawMax or EdrawMax Online to create a network diagram to understand the flow of packets in a telecommunication network architecture.
