In the past, different vertical networks addressing different needs and distinctive networks with definite management strategy were the easiest approaches taken by operators. However, in a world where operators need to find ways to differentiate their offer- ings and keep the margins healthy, the above "stovepipe" approach is no longer sufficient and could hamper good business practice. With advances in technology, the communications network and its manage- ment are becoming more complex as well as more dynamic and fluid in nature. As with any other field of study involving the term management, the world of telecom- munications management also tends to be opaque and filled with jargon and ter- minology. It is a field that would benefit immensely from literature that demystifies and simplifies all its various aspects. Fundamentals of EMS, NMS, and OSS/BSS has excellent coverage of the basics of telecom management, from legacy management systems to the next generation systems. In this book, Jithesh introduces the principles of EMS, NMS, and OSS/ BSS and goes in-depth on implementation guidelines including the most com- mon design patterns in use. This book makes two important contributions. First, it shows the roles that EMS, NMS, and OSS/BSS can play in the telecom environ- ment with complex real-time systems. Second, it provides a very realistic view of use cases and implementation examples
