In this practical book, Juniper Networks consulting senior network engineer, Peter Southwick, offers unique first-person field studies on designing, configuring, and troubleshooting new systems that are changing the networking world. Each chapter-long "travelogue" follows a team of Juniper Networks warriors as they solve specific needs with emerging network platform architectures. In these case studies, Southwick and his fellow warriors analyze a client’s particular situation, arrive at an architectural solution, and work through the deployment details. For anyone who operates, installs, designs, or works in IT, this book provides an intimate and entertaining look at what’s changing and why. Among the case studies, you’ll discover how: A service provider protected customers from malicious traffic with Juniper Networks IDP systems SRX5800s improved connectivity and security in a data center Ethernet WAN technology was chosen as a storage solution, rather than a proprietary design on dark fiber An enterprise severed communications between different departments to comply with government personal credit card standards Core network and edge devices helped a power company serve local customers and ISPs in the data services market A hosting company migrated its core, datacenter, edge, and access domains to a state-of-the-art network "In this uniquely written book, you will get a detailed view of life in the data center, the edge, the core, and the office of the customer’s CIO." Steve Fazio, CEO, TorreyPoint

Pick up where certification exams leave off. With this practical, in-depth guide to the entire network infrastructure, you’ll learn how to deal with real Cisco networks, rather than the hypothetical situations presented on exams like the CCNA. Network Warrior takes you step by step through the world of routers, switches, firewalls, and other technologies based on the author's extensive field experience. You'll find new content for MPLS, IPv6, VoIP, and wireless in this completely revised second edition, along with examples of Cisco Nexus 5000 and 7000 switches throughout. Topics include: An in-depth view of routers and routing Switching, using Cisco Catalyst and Nexus switches as examples SOHO VoIP and SOHO wireless access point design and configuration Introduction to IPv6 with configuration examples Telecom technologies in the data-networking world, including T1, DS3, frame relay, and MPLS Security, firewall theory, and configuration, as well as ACL and authentication Quality of Service (QoS), with an emphasis on low-latency queuing (LLQ) IP address allocation, Network Time Protocol (NTP), and device failures

Written by networking veteran with 20 years of experience, Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well. Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers: The type of networks now in use, from LANs, WANs and MANs to CANs The OSI Model and the layers involved in sending data Hubs, repeaters, switches, and trunks in practice Auto negotiation and why it 's a common problem in network slowdowns Route maps, routing protocols, and switching algorithms in Cisco routers The resilient Ethernet -- how to make things truly redundant Cisco 6500 multi-layer switches and the Catalyst 3750 switch Telecom nomenclature -- why it 's different from the data world T1 and DS3 Firewall theory, designing access lists, authentication in Cisco devices Server load balancing technology Content switch module in action Designing QOS and what QOS does not do IP design and subnetting made easy The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

When it comes to network security, many users and administrators are running scared, and justifiably so. The sophistication of attacks against computer systems increases with each new Internet worm.What's the worst an attacker can do to you? You'd better find out, right? That's what Security Warrior teaches you. Based on the principle that the only way to defend yourself is to understand your attacker in depth, Security Warrior reveals how your systems can be attacked. Covering everything from reverse engineering to SQL attacks, and including topics like social engineering, antiforensics, and common attacks against UNIX and Windows systems, this book teaches you to know your enemy and how to be prepared to do battle.Security Warrior places particular emphasis on reverse engineering. RE is a fundamental skill for the administrator, who must be aware of all kinds of malware that can be installed on his machines -- trojaned binaries, "spyware" that looks innocuous but that sends private data back to its creator, and more. This is the only book to discuss reverse engineering for Linux or Windows CE. It's also the only book that shows you how SQL injection works, enabling you to inspect your database and web applications for vulnerability.Security Warrior is the most comprehensive and up-to-date book covering the art of computer war: attacks against computer systems and their defenses. It's often scary, and never comforting. If you're on the front lines, defending your site against attackers, you need this book. On your shelf--and in your hands.

This cultural history of Ancient Sparta chronicles the rise of its legendary military power and offers revealing insight into the people behind the myths. The Spartans of ancient Greece are typically portrayed as macho heroes: noble, laconic, totally fearless, and impervious to pain. And indeed, they often lived up to this image. But life was not as simple as this image suggests. In truth, ancient Sparta was a city of contrasts. We might admire their physical toughness, but Spartans also systematically abused their children. They gave rights to female citizens that were unmatched in Europe until the modern era, meanwhile subjecting their conquered subject peoples to a murderous reign of terror. Though idealized by the Athenian contemporaries of Socrates, Sparta was almost devoid of intellectual achievement. In this revealing history of Spartan society, Philip Matyszak chronicles the rise of the city from a Peloponnesian village to the military superpower of Greece. Above all, Matyszak investigates the role of the Spartan hoplite, the archetypal Greek warrior who was feared throughout Greece in his own day and has since become a legend. The reader is shown the man behind the myth; who he was, who he thought he was, and the environment which produced him.

Though Arista Networks is a relative newcomer in the data center and cloud networking markets, the company has already had considerable success. In this book, renowned consultant and technical author Gary Donahue (Network Warrior) provides an in-depth, objective guide to Arista’s lineup of hardware, and explains why its network switches and Extensible Operating System (EOS) are so effective. Anyone with a CCNA or equivalent knowledge will benefit from this book, especially entrenched administrators, engineers, or architects tasked with building an Arista network. Is Arista right for your data center? Pick up this guide and find out. Topic highlights include: SysDB: the EOS system database that holds state, statuses, and variables Multichassis Link Aggregation (MLAG): for linking a port-channel to multiple switches instead of just one Latency Analyzer (LANZ): the interface-buffer troubleshooting tool with a reporting granularity of one millisecond VM Tracer: for adding, changing, and removing VLANs without human interaction Zero-Touch Provisioning (ZTP): for remote switch configuration Hardware advantages: including merchant silicon, low-latency networking, and power consumption Gotchas: issues with Arista switches or systems
