The telecommunications network is a global system of equipment and means that ensures the connections between the users of communication services, with the transmission and reception of the information involved. It is a set of communication nodes, in which processing procedures take place for the transmission and reception of information signals, switching connections and choosing routes between nodes to make connections between sources and destinations of communications, and a set of links between these nodes, made in a variety of technologies. This volume contains 5 chapters in which the different processes and types of systems within the telecommunications network are presented.

Go beyond layer 2 broadcast domains with this in-depth tour of advanced link and internetwork layer protocols, and learn how they enable you to expand to larger topologies. An ideal follow-up to Packet Guide to Core Network Protocols, this concise guide dissects several of these protocols to explain their structure and operation. This isn’t a book on packet theory. Author Bruce Hartpence built topologies in a lab as he wrote this guide, and each chapter includes several packet captures. You’ll learn about protocol classification, static vs. dynamic topologies, and reasons for installing a particular route. This guide covers: Host routing—Process a routing table and learn how traffic starts out across a network Static routing—Build router routing tables and understand how forwarding decisions are made and processed Spanning Tree Protocol—Learn how this protocol is an integral part of every network containing switches Virtual Local Area Networks—Use VLANs to address the limitations of layer 2 networks Trunking—Get an indepth look at VLAN tagging and the 802.1Q protocol Routing Information Protocol—Understand how this distance vector protocol works in small, modern communication networks Open Shortest Path First—Discover why convergence times of OSPF and other link state protocols are improved over distance vectors

Switching and routing are two types of procedures having the same fundamental purpose which is transferring information between different users of communication networks. But, while routing must be viewed at the overall level of the communication network, the information being exchanged between network nodes, switching refers to operations involving a single communication node, the information being transferred between its input / output access ports. It should also be noted that the routing is executed according to a routing protocol used on the network, while the switching is based on elements belonging to a single node in the network, namely its switching structure, routing table and path selection algorithm between ports.

Routing, also known as forwarding, is a function located in one or more layers of the stack of communication protocols. It aims to select paths in a network along which sent source traffic to destinations while satisfying the needs of users and considering the technical and administrative capabilities of service providers.
