Deployment Option:	Onsite Training
Course Price:	$1499.00

Who Should Attend:

This course is useful for network engineers and managers who have responsibility in the following functional areas: network design, network management, network operations, network engineering and information systems. Internet providers and managers in enterprise organizations who have telecommunications or network responsibility can benefit.

Prerequisites:

This course has no prerequisites

Course Description:

This course provides the concepts you need to understand Asynchronous Transfer Mode (ATM) in both practice and potential. This class lays the foundation for ATM by explaining all the basics from formats and headers to virtual circuits and connections. We also explore the evolution to an ATM network from a non-ATM network. You will gain a business perspective on how ATM compares with alternative technologies, review the many interfaces, and examine the protocol. In addition to an ATM overview, specific topics featured in this course include: congestion control, the adaptation layer, carrier services, ATM backbones, IP over ATM, voice and video over ATM, Private Network-to-Network Interface (PNNI), MPLS and ATM standard interfaces.
