Junos Enterprise Switching

JUNOS Enterprise Switching is the only detailed technical book on Juniper Networks' new Ethernet-switching EX product platform. With this book, you'll learn all about the hardware and ASIC design prowess of the EX platform, as well as the JUNOS Software that powers it. Not only is this extremely practical book a useful, hands-on manual to the EX platform, it also makes an excellent study guide for certification exams in the JNTCP enterprise tracks. The authors have based JUNOS Enterprise Switching on their own Juniper training practices and programs, as well as the configuration, maintenance, and troubleshooting guidelines they created for their bestselling companion book, JUNOS Enterprise Routing. Using a mix of test cases, case studies, use cases, and tangential answers to real-world problems, this book covers:Enterprise switching and virtual LANs (VLANs) The Spanning tree protocol and why it's needed Inter-VLAN routing, including route tables and preferences Routing policy and firewall filters Switching security, such as DHCP snooping Telephony integration, including VLAN voice Part of the Juniper Networks Technical Library, JUNOS Enterprise Switching provides all-inclusive coverage of the Juniper Networks EX product platform, including architecture and packet flow, management options, user interface options, and complete details on JUNOS switch deployment.

Interconnections, 2nd Edition

This latest release of Interconnections is a competent update of a networking classic. Radia Perlman explains hundreds of details about getting computers--and computer networks--to talk to one another smoothly, accurately, and efficiently. Perlman, inventor of the spanning-tree bridging algorithm, covers the Open Systems Interconnect (OSI) reference model, bridges, switches, hubs, Virtual Local Area Networks (VLANs), plus connection-based and connectionless networks. She also does a great job of explaining the underpinnings of internetworking protocols, including packet format, addressing, routing (both generically and in terms of RIP, RTMP, OSPF, and other protocols), and security. There's plenty of IPv6 information here, mostly from a theoretical vantage point. The best parts of Perlman's approach to her subject are the little thought experiments that explain why various aspects of internetworking behave the way they do. For example, Perlman talks about Maximum Transmission Unit (MTU) discovery by presenting four different hypotheses for figuring out MTU. For each possible solution, she discusses strengths, weaknesses, and real-life considerations. She applies this method to dozens of other problems and phenomena, making Interconnections a very close approximation of learning by experiment. --David Wall Topics covered: Open Systems Interconnect (OSI) reference model, bridges, switches, hubs, Virtual Local Area Networks (VLANs), and internetworking protocols.

Packet Guide to Routing and Switching

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.
