Definitive MPLS Network Designs provides examples of how to combine key technologies
at the heart of IP/MPLS networks. Techniques are presented through a set of
comprehensive design studies. Each design study is based on characteristics
and objectives common to a given profile of network operators having deployed
MPLS and discusses all the corresponding design aspects.
The book starts with a technology refresher for each of the technologies involved
in the design studies. Next, a series of design studies is presented, each based
on a specific hypothetical network representative of service provider and enterprise
networks running MPLS. Each design study chapter delivers four elements. They
open with a description of the network environment, including the set of supported
services, the network topology, the POP structure, the transmission facilities,
the basic IP routing design, and possible constraints. Then the chapters present
design objectives, such as optimizing bandwidth usage. Following these are details
of all aspects of the network design, covering VPN, QoS, TE, network recovery,
and—where applicable—multicast, IPv6, and pseudowire. The chapters
conclude with a summary of the lessons that can be drawn from the design study
so that all types of service providers and large enterprise MPLS architects
can adapt aspects of the design solution to their unique network environment
and objectives.
Although network architects have many resources for seeking information on
the concepts and protocols involved with MPLS, there is no single resource that
illustrates how to design a network that optimizes their benefits for a specific
operating environment. The variety of network environments and requirements
makes it difficult to provide a one-size-fits-all design recommendation. Definitive
MPLS Network Designs fills this void.
“This book comes as a boon to professionals who want to understand the
power of MPLS and make full use of it.”

Case Studies and Straw Men
Why is MPLS being implemented so widely? To get your arms around this, you need to divide the question somewhat, and take a look at the different flavors of service providers and carriers that are building MPLS networks. In Definitive MPLS Network Designs, the authors have created strawmen for an Interexchange Carrier (USCom), a National Telco (Telecom Kingland), a Global Service Provider (Globenet), and a monstrously large enterprise (EuroBankwhich seems to have swallowed up so many other European banks as to be a kind of virtual service provider in its own right).
All four of these mythical entities build Layer 3 MPLS services, but they each have different requirements for QoS, restoration, traffic engineering, and other services provided by MPLS. USCom is a long distance voice service provider who needs very fast (telco quality) recovery over unprotected core transport. Telecom Kingland is adding a multiservice backbone that will be trunking public telephony as well as new services such as IPv6 and carrier of carrier services (in which all VPNs from one carrier are trunked in a single VPN across another carriers backbone). GlobeNet has unique traffic engineering concerns and a need to create viable peering agreements with local service providers in order to provide services in a shared fashion. Thus, inter-AS Layer 3 VPNs are discussed in detail here. EuroBank, with its vast resources, is building out its own MPLS core to support the variety of access infrastructures it has inherited. Each of these strawmen are described in terms of their design objectives, the services they offer, their topologies, and the constraints that lead to the choices made in building out these networks. Configuration snippets are provided throughout for illustration purposes.
The problem that this book solves is that there really is no one-size-fits-all design for any network technology, and MPLS is no exception. The set of services offered by network operators and enterprises vary greatly from one implementation to the next, and the best you can do is try to scaffold a set of likely use cases and thus provide a starting point for the network designers and engineers that have to take on unique project.
These case studies all validate the reasons that MPLS has emerged as a way to give you the simplicity and power of Layer 3 networks and still retain everything you loved about your last generation Layer 2 Frame Relay or ATM networkthe per-subscriber separation of virtual circuits, robustness against attacks, and the virtualization of the core infrastructure. The real sale in terms of manageability is the ability to maintain only a single converged network instead of many disparate networks. Initially it was the traffic separation capabilities in the form of Layer 3 VPNs that put MPLS on the way to wide acceptance, but with the growth of multimedia traffic and the trends towards advanced network services, the demand for resiliency, restoration and traffic engineering on a scale more commonly associated with optical transport has provided another wide area for MPLS to show its strengths.
Chances are that any network engineer responsible for turning up or maintaining an MPLS network is only going to be responsible for a network resembling one of the reference designs illustrated in this book. But it is well worth browsing all the different implementations to get an idea of the power of MPLS to fit into these different models. Finally, what really drives this book to 5 stars is the comprehensive technology primers it provides before even getting into the case studies. The first chapter is more edge-oriented and provides an excellent backgrounder on MPLS VPN services, as well as multicast, IPv6, and pseudowire. Chapter 2 covers core issues such as the many varieties of MPLS traffic engineering and QoS facilities. These chapters give you most of the hooks you need to hang onto the concepts that are introduced in the case studies, and they provide nice reference material in general to get a feel for these technologies before you go digging through the documentation for implementation specifics.
