The definitive guide to Enterprise and Carrier Metro Ethernet applications
Metro networks will emerge as the next area of growth for the networking industry and will represent a major shift in how data services are offered to businesses and residential customers. The metro has always been a challenging environment for delivering data services because it has been built to handle the stringent reliability and availability needs for voice. Carriers will have to go through fundamental shifts to equip the metro for next-generation data services demanded by enterprise customers and consumers. This is not only a technology shift, but also a shift in the operational and business model that will allow the incumbent carriers to transform the metro to offer enhanced data services.
Metro Ethernet from Cisco Press looks at the deployment of metro data services from a holistic view. It describes the current metro, which is based on TDM technology, and discusses the drivers and challenges carriers will face in transforming the metro to address data services.
Metro Ethernet discusses the adoption of metro Ethernet services and how that has led carriers to the delivery of metro data services. With a changing mix of transport technologies, the book then examines current and emerging trends, and delves into the role of virtual private networks (VPN), virtual private local area networks (VLAN), virtual private LAN services (VPLS), traffic engineering, and MPLS and Generalized MPLS (GMPLS).

Sam Halabi's book is described on the cover as "the definitive guide to enterprise and carrier metro Ethernet applications". As you would expect from the author of the justly-celebrated "Internet Routing Architectures", Halabi does a superb job.Chapter 1 reviews traditional TDM ways of getting to the customer. With traditional SDH/SONET-based transmission, carriers pay a high price in operational complexity, cost and provisioning delay. Ethernet's advantages include fast provisioning, fine-grained bandwidth granularity (inherent in packet technologies) and a scalability from kbps to Gbps. The customer also expects a lower cost service, although carrier pricing remains volatile, partially from fear of cannibalising their existing connectivity revenues. Chapter 2 looks at metro Ethernet technologies. Carriers with already deployed SONET/SDH networks naturally consider how to use them efficiently to carry Ethernet. The problem of mapping continuously-scalable packet flows into the... Read more

I recently read the book titled "Metro Ethernet", authored by the legendary Sam Halabi. ISBN: 158705096X. Let me be the first to say that this title lives up to Mr. Halabi's high standards for delivering top quality information. Sam Halabi does an excellent job of taking away the smoke and mirrors of the often misunderstood world of Metro Ethernet. This book explains, in superb detail, every way to skin the Metro Ethernet cat. The author does it in a way that helps to give the reader a complete understanding of a particular application of Metro Ethernet without dropping the reader off the deep-end of this hybrid technology. The book is organized very well. The author has taken a crawl, walk, run approach to the layout of this book. The introduction alone gives the reader a great road map of the book, so the reader can pinpoint a given topic, rather quickly. In the past I've had to rely heavily on the Index to provide pointers to a given topic, but the Introduction of this book...

Sam Halabi did it again.This is a rare and very informative book on Metro Ethernet developments.It has very clear explanation on all the subjects.I particularly like the VPLS section.One thing tough,the HVPLS section needs to have more coverage on real world scenario. |
Introduction.
I. ETHERNET: FROM THE LAN TO THE MAN.
II. MPLS: CONTROLLING TRAFFIC OVER YOUR OPTICAL METRO.
