Описание: Next-generation networks, or NGNs, have emerged through several key drivers:
- Industry drive toward IP as the converged network layer protocol for applications
- IP network technology evolving toward multiservice, carrier-class, and high-bandwidth
capabilities
- The opportunity for consolidation of disparate network infrastructures and
operational teams
The emergence of the Internet and IP has fueled unprecedented growth in IP-capable desktop
and laptop computers. This trend has quickly been embraced by the enterprise sector in terms of productivity tools for workers. Desktop applications such as word processors, spreadsheets, and electronic mail have revolutionized the workplace, allowing much greater effciency and cost effectiveness in companies of every size. Vendors realized the potential to disrupt entrenched communication technologies, such as voice and video, driving cheaper, more feature-rich IP products into these markets. This revolution heralded IP as the converged protocol for communications. The modern mobile phone, based on 3G or 4G, uses IP exclusively for communication of voice, signaling, and data, giving a reference for the extensive penetration of IP into application transport.
