A new era of network services has evolved to meet the needs of IP-centric networking requirements and customer opportunity. The emphasis is on service as IP has become a prolific communications portal through which to deliver interactive solutions that improve business execution, tie the individual consumer into commerce, and extend market reach by removing the last barriers of time and distance.
Next-Generation Network Services presents an overview of converged IP network services, focusing on opportunities for service differentiation and introducing current service-oriented technology. These technologies allow service providers and large enterprises to build and operate networks that provide local, long-haul, mobile, and global data and Internet services to businesses and consumers.
This book explores the service provider opportunity in the new era, discussing what has changed and why a service-centric focus is the new ascendancy. This book introduces an extensive portfolio of network technologies and explains the market advantages and the service value of each solution, including IP, multiservice, virtual private network (VPN), optical, wireline, and wireless networks.
Whether you are a network architect or engineer driving service innovation within a service provider or enterprise network, or you are a network executive or technology analyst looking to gain a broad overview of the telecommunications sector, Next-Generation Network Services offers you insight into the evolving internetworking technologies that will shape the future of network growth.
