Understanding Next Generation Architectures
Book Now - 2 Delivery Methods Available:Scheduled Online Onsite
This course will provide engineers, sales and product management staff with an introduction to this new technology, how it has evolved and how it can be used. It will give an understanding of the protocols used as well as providing examples of the business potential for such new infrastructures.
The next generation of telecommunications networks will deliver broadband data and multimedia services to users over a common Multi-Service Infrastructure. Circuit switched voice services will replaced with IP packet switched infrastructures that will carry TV, video multi-media and Voice over IP. Streams of real time media will be switched between gateways under the control of call servers and media gateway controllers. The key to this new soft-switch technology will be the protocols that run between the Media Gateway Controllers and the switched core. The heart of the service will be IP running over MPLS and Gigabit Ethernet or SDH.
- Consider the business potential for current and future services
- Summarize architecture and technology options for Multi-Service Networks
- Identify the key technologies for core, access and infrastructure
- Examine benefits and limitations of SDH, ATM, IP, VoIP and Media Distribution
- Provide an understanding of likely future service demands.
