Frame Relays enjoy worldwide popularity, with most major service providers around the globe offering Frame Relay as one of their core services. It has become an important technology for connecting data networks across North America, Europe, and Asia. To meet the needs of the audience, Cisco Frame Relay Solutions Guide provides a collection of solution strategies for IT professionals looking to build more versatile, reliable, and efficient Frame Relays.
Part I begins by describing the basics of the technology, including the introduction of Cisco's Frame Relay implementation, followed by the configuration basics of Frame Relay on Cisco IOS. Part II, Cisco Frame Relay Solutions for Traffic Congestion and Management, tackles the configuration tasks for traffic shaping, router foresight, switching enhancements, SVC support, Frame Relay-to-ATM internetworking, PPP, and PVC bundles. Part III addresses the need for compression and fragmentation, providing solutions to common problems such as slow links, how to save bandwidth, when to use payload compression, and what to do when the network cannot support the original size of a particular packet. Part IV introduces congestion management solutions, and part V discusses Congestion Avoidance andSignaling. Within each chapter, the book addresses commons problems; details the associated solution, including configuration and command examples; and ends with a detailed, real-world case study based on a tested Cisco solution.

Jonathan Chins Cisco Frame Relay Solutions Guide (ISBN: 1587051168, Cisco Press) is a new book on an older WAN technology widely deployed in small companies, the enterprise, and service provider networks: Frame Relay. Although one might think that many Cisco Press Frame Relay books exist, there really are none that cover the technology comprehensively, including newer advancements in Frame Relay technology. The closest document would be the Cisco IOS Wide Area Networking Configuration Guide found online or on the Cisco Documentation CD. Jonathan Chin takes many technical aspects and explains them in friendlier terms with IOS command examples and case studies to reinforce the theory. His book includes twenty-two chapters broken out into five major categories: Frame Relay Technology, Policing & Shaping, Traffic Management, Congestion Management, Congestion Avoidance & Signaling. Just by looking at the major section headers, it is obvious that the book focuses on QoS strategies in a Frame Relay environment, and this is the real value and uniqueness of the book as it discusses updated modular QoS CLI (MQC) best practices in a Frame network. Frame Relay traffic shaping (FRTS) with low latency queuing (LLQ) and class based weighted fair queuing (CBWFQ) is a great example of a real world Frame/QoS strategy that is well documented in this book. FRF.12 fragmentation, compression, and FRF.16 multilink Frame Relay are other topics that Chin covers and helps to clarify their context and possible uses. Aside from QoS techniques, Chin also covers lesser known Frame Relay technologies such as PPP over Frame, Frame SVCs, and X.25 over Frame. Lastly, Chin spends some time going through different ways to configure a Cisco router to act as a Frame Relay switch, and what types of QoS can be used in those scenarios. Again, the QoS sections of the book are good and helpful, although at times it seems that too many different topics are covered leaving less in-depth details for any one topic. Readers familiar with MQC will have a much easier time with the book than those who havent spent anytime working with or investigating QoS strategy. The major drawback to the book is that it includes some sections that could either be reduced or not included at all. The first 90 pages are devoted to basic Frame Relay technology which in one sense is to be expected in a Frame Relay Solutions Guide, but on the other is unnecessary given that the basics are well documented elsewhere. Chin works in the Fancy Queuing techniques of Priority and Custom queuing on different occasions in the book, which at some level is more a topic of historical knowledge than real world practical. The MQC configs are much more valuable and applicable; more time should have been spent in those areas instead of priority queuing. The X.25 over Frame was a perplexing chapter as Chin states that the use of X.25 protocol on network backbones is fast becoming obsolete (p.332). Again, interesting from a posterity perspective, but the reality is that X.25 is obsolete. Chin would have better served his reading audience by providing just two major categories: Advanced Frame Relay technologies (PPP, Frame/ATM, ELMI Switching, etc) and Frame Relay QoS technologies (FRTS, fragmentation, compression, RSVP, WRED, etc.). The Cisco Frame Relay Solutions Guide has good information for the small company up to the enterprise and even at the service provider level, especially as it pertains to QoS. Some of the other advanced Frame technologies may be useful at the enterprise level, but the coverage depth is too shallow for the service provider. This is a good book to see what Frame Relay can do outside of configuring your standard PVCs and when you need to deploy QoS. It is not comprehensive or deep enough, however, to stand as an authoritative source for Frame Relay.
A very well written and complete book on Frame Relay technology. Provides an indepth insight to the design of FR networks. A good tool to understanding FR.
The title is accurate because the author begins each chapter with certain problems that are encountered with Frame Relay. Then he spends that chapter demonstrating how Cisco has addressed these obstacles with new features in their Internetwork Operating System (IOS). Chin deals with the problems of multi-access Frame Relay, but dedicates more time to hub-and-spoke networks, since this is the most common type seen in the industry. There are so many options for shaping and managing traffic across the Frame Relay links with the newer versions of the Cisco IOS. And Chin explains them all showing how they solve existing limitations and what new limitations they bring, if any. When a new feature is presented, he usually charts out the advantages and disadvantages of the new versus the old configurations. I found the book easy to use and tested some of the configurations and found them accurate and true. I could not find any proof-text errors either, rare in computer books. The reader should have some basic knowledge of wide area networking to find the information in the Cisco Frame Relay Solutions Guide useful. The person who will get the most use from the book is the service provider offering complete end-to-end solutions for customers who are looking to maximize their network budget. Network Administrators throughout the industry will find it useful for managing the Frame Relay network they lease. There are some examples of what can be done on only the end DTE routers, without the help of the service provider. This text would also be helpful to anyone preparing for the CCIE or the CCNP Remote Access exams. The author and the two technical reviewers all hold the CCIE certification. The chapters have excellent references with review questions. Nine of the chapters include case studies where real life problems are problems are described and solutions are shown with configurations. The author obviously has an excellent lab where the solutions were tested and documented. The author also presents solutions that would be helpful in countries where the infrastructure is out-dated. One nice trick is multi-plexing multiple DLCIs to increase bandwidth where a full T1 is not possible. I give this book a five star rating for layout, accuracy, and usefulness.
