Go under the hood of an operating Voice over IP network, and build your knowledge of the protocols and architectures used by this Internet telephony technology. With this concise guide, youll learn about services involved in VoIP and get a first-hand view of network data packets from the time the phones boot through calls and subsequent connection teardown.With packet captures available on the companion website, this book is ideal whether youre an instructor, student, or professional looking to boost your skill set. Each chapter includes a set of review questions, as well as practical, hands-on lab exercises.Learn the requirements for deploying packetized voice and videoUnderstand traditional telephony concepts, including local loop, tip and ring, and T carriersExplore the Session Initiation Protocol (SIP), VoIPs primary signaling protocolLearn the operations and fields for VoIPs standardized RTP and RTCP transport protocolsDelve into voice and video codecs for converting analog data to digital format for transmissionGet familiar with Communications Systems H.323, SIPs widely used predecessorExamine the Skinny Client Control Protocol used in Cisco VoIP phones in networks around the world

Take an in-depth tour of core Internet protocols and learn how they work together to move data packets from one network to another. With this updated edition, youll dive into the aspects of each protocol, including operation basics and security risks, and learn the function of network hardware such as switches and routers. New chapters examine the transmission control protocol (TCP) and user datagram protocol in detail.Ideal for beginning network engineers, each chapter in this book includes a set of review questions, as well as practical, hands-on lab exercises.Youll explore topics including:Basic network architecture: how protocols and functions fit togetherThe structure and operation of the Ethernet protocolTCP/IP protocol fields, operations, and addressing used for networksThe address resolution process in a typical IPv4 networkSwitches, access points, routers, and components that process packetsTCP details, including packet content and client-server packet flowHow the Internet Control Message Protocol provides error messages during network operationsHow network mask (subnetting) helps determine the networkThe operation, structure, and common uses of the user datagram protocol

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 isnt 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. Youll learn about protocol classification, static vs. dynamic topologies, and reasons for installing a particular route.This guide covers:Host routingProcess a routing table and learn how traffic starts out across a networkStatic routingBuild router routing tables and understand how forwarding decisions are made and processedSpanning Tree ProtocolLearn how this protocol is an integral part of every network containing switchesVirtual Local Area NetworksUse VLANs to address the limitations of layer 2 networksTrunkingGet an indepth look at VLAN tagging and the 802.1Q protocolRouting Information ProtocolUnderstand how this distance vector protocol works in small, modern communication networksOpen Shortest Path FirstDiscover why convergence times of OSPF and other link state protocols are improved over distance vectors
