Carrier-grade software must satisfy the stringent quality requirements of network operators whose systems provide mission-critical communications services. This book describes proven carrier-grade software techniques used in flagship products designed by industry leaders such as Lucent, Nortel, and Ericsson.

In the age of 24/7, software robustness is a competitive advantage. This authoritative guide for software engineers, managers, and testers of products that face carrier-grade requirements helps you to develop state-of-the-art software that will give you an edge in today’s marketplace.

Robust Communications Software: Extreme Availability, Reliability and Scalability for Carrier-Grade Systems

• offers advice on choosing the right technologies for building reliable software
  
• incorporates real-world examples and design rationales when describing how to construct robust, embedded software for communications systems
  
• presents a comprehensive set of carrier-grade design patterns that help you to meet extreme availability, reliability, scalability, and capacity requirements
  
• gives advice on how to protect against and recover from software faults
  
• discusses system installation, operability, maintenance, and on-site debugging

'Because of the recent debacle in the telecom sector, an entire domain of expertise is disappearing. Designers who knew about the topics in this book--availability, reliability, and scalability--have moved on to other things. The void that patterns fill has never been wider and deeper. I am so thankful that Greg has documented these vital techniques. The need for them will always be with us, and this book provides us with a solid reference.' Linda Rising, author of The Patterns Handbook, The Pattern Almanac, Design Patterns in Communications Software, and Introducing Patterns into Organizations

'In this book, Greg really cuts to the core of those elements of software architecture that I've found to be necessary to build a highly available, highly scalable system.' Bob Hanmer, Lucent Technologies

'You cannot add robustness by adding if statements. It must be designed in from the beginning. This book is an important contribution to the design of robust software.' Dennis DeBruler, Lucent Technologies
