Network Mergers and Migrations: Junos Design and Implementation

Description

This book provides a complete reference to network mergers and migrations using the Junos operating system Network Mergers and Migrations provides readers with a comprehensive guide for network migration activities by detailing a variety of internetworking case studies. Both enterprise and service provider scenarios are examined based on the experience and expertise of two senior Juniper Networks engineers. From MPLS Layer 3 VPN migration approaches to comprehensive network protocol consolidation and integration, each case study covers planning, design and implementation, as well as discussing alternatives and leveraging additional specific services and Junos resources, to ensure successful completion at each migration phase. These case studies are complemented with solid state-of-the-art protocol analysis and with practical application notes focused on specific functionalities. Readers are shown, not told, how to accomplish one of the more critical tasks of modern day networking – merging two or more networks or migrating one into the other. This is a book that truly describes the challenges that involve networks in modern environments, in both enterprise and service provider milieus. Key Features: Provides an invaluable reference for engineers needing to upgrade networks, consolidate activities, or deploy new features or services. Contains case studies and application notes of network migrations, moving well beyond theoretical technology descriptions. Offers advanced techniques from engineers who have planned, designed, and accomplished complicated internetwork migrations, offering lessons learned from their success stories and pitfall situations. Covers specific Junos resources for routing tables, link-state interior gateway protocols, BGP, MPLS label distribution protocols, MPLS Layer 3 VPN and many more Junos related features and functionalities Network Mergers and Migrations will be of immense interest to network engineers, network designers, architects, and operators, as well as network planners and consultants. Networking engineering students will discover a treasure trove of real-world scenarios and solutions and the book is additional recommended reading for students pursuing Juniper Networks Technical Certification Programs. Endorsements: ''Having been through the network migrations of both SBC-Ameritech, and SBC-AT&T, this book provides valuable direction and advice to an operator that would be useful when dealing with mergers and migrations. It is about time that someone wrote a book covering not just green field network design, but how do you merge networks together while maintaining the needs of the business.” Tom Scholl, Principal IP Network Engineer, IP/MPLS Backbone Design and Development, AT&T Labs “I have never read such an excellent book detailing so much about Juniper router operation and design knowledge in depth, not only it has helped me with operating all of our Juniper routers in our national backbone network more efficiently, but also on improving my design knowledge as well.” Ji Hui, Senior Manager, China Telecom Group Corporation “ NMM gives a clear idea of the difficulty of merging or migrating IP networks, and it is a great help for engineers that have to face this type of operation for the first time or even repeatedly.” Chiara Moriondo, Senior Engineer, Telecom Italia Labs “ Network Mergers and Migrations provides an original approach to IP and MPLS instruction that is right on target. When combined with the depth of technical information and case studies contained within, the result is an irreplaceable resource for any network engineer.” Chris Grundemann, Senior Engineer, tw telecom , inc. “Network Mergers and Migrations is a thorough guide for anyone involved in a wide range of network consolidation and integration exercises. The authors use Junos as a technical focus for their examples keeping the concepts related to some of the more relevant protocols and topics in current IP and MPLS networks. It’s a must-have book for anyone wishing to further enhance their protocol knowledge base.” Shafik Hirjee, Bell Canada, Director, National MPLS/IP Core Network Engineering “We operate the largest R&E network in the world using Juniper T640s, and my job often involves network planning and design. I have found this book to be just the one I need. I thought I knew Junos, but these authors are at an unprecedented level.” Zheng Zhiyan, Senior Engineer, Network Operation Center, CNGI-6IX/CERNET2 “Recommend reading for networkers who like to look into complex and detailed network migration scenarios, as well as those interested in a better understanding of Junos implementation of common ISP protocols.” Andreas Weiner, Network Engineer/IP Backbone, Telekom Austria TA AG “ Network Mergers and Migrations provides network operators a comprehensive reference for network migration. The level of detail included in this book is exceptional. It's a thorough guide for any network professional who are involved with network migration.” Mazen A. Baragaba & Eid Al HarbiCommunications Engineers, Communications operations department, Saudi Aramco “Efficient IP network planning and management involves more than just the in-depth knowledge of theory. This book helps the reader gain a thorough understanding of the Junos routing architecture via practical and useful case studies, resulting in smooth and clean transitions between different network implementations. The clear and concise exposition make this book a pleasure to read and a useful companion during work.” Giorgio Lembo, R&D Director, Tinet S.p.A. “ Network Mergers and Migrations describes in detail the basics of L3VPN architectures while providing a clear and detailed roadmap for various migration scenarios. Even for telcos (operators) that are not implied in migration phases, a lot of great advice is provided for designing network architectures based on Junos software.” David Roy, Orange France, RBCI IP Technical Assistance Center “ Network Mergers and Migrations is much more than a reference for all relevant IP protocols today, it is a book of practical examples for your daily work and should be on the desk of everyone who has to deal with network migrations and mergers.” Christian Kaufmann, Senior Manager Network Architecture, Akamai Technology “An invaluable guide for anyone about to undertake a network merger, full of appropriate case studies and Junos tips to back up the concepts discussed.” Keith Slater, NOC Manager, Cable&Wireless Worldwide “The best book on operating Junos router networks!” Jia Yan, Director, Network Maintenance Center, China Telecom Group Beijing Corporation
