Dates, Locations and Registration


This network training course provides a foundation in the technology, terminology and network configurations used in commercial data communications. An end-to-end view of the equipment, network services and business processes employed is presented, focusing on the business justification, decision processes and practical considerations in building and maintaining these networks. While the topics are technical, the presentation makes these issues accessible and meaningful to both business and technical managers.

Who Should Attend
This training seminar is ideal for communications analysts/managers, equipment vendors, and carrier representatives who need an objective, business-oriented understanding of data communications applications, services, and technologies.

By attending this training program, you will learn About:

  • Major data and VOIP network configurations that are used in enterprise environments, and the mix of equipment, technology, and network services that are used to support them.
  • The fundamental differences between circuit and packet communications and understand the major quality of service (QOS) options to insure quality and performance of both voice and data applications.
  • OSI Reference Model, how TCP/IP incorporates those concepts, and describe the IP protocols used to support voice and data applications.
  • How the Internet is put together, and why new services like MPLS VPNs are replacing frame relay as we move toward converged voice and data networks.
  • How router networks are configured, how the overall process of routing works, and how Quality of Service features like MPLS and DiffServ are delivered.
  • The range of security issues that that must be addressed in data and VOIP networks, the major attack strategies that are employed, and understand the role of firewalls, intrusion detection systems, network access control, SSL/VPN secure tunnels, and the other tools used to combat them.
  • Wired and wireless LANs, the evolving cabling options, and how features like virtual LANs (VLANs) and QOS impact the network's ability to in support an IP PBX deployment.
  • Range of wide area network services that are available, their overall capacities, pricing elements, and their ability to provide QOS and other features to support converged networks
  • Range of broadband access options that can be used for telecommuter and remote access applications and describe their abilities with regard to both voice and data services.
  • The expanding range of wireless services including Wi-Fi Hot Spots, Muni Wi-Fi, WiMAX, and 2.5G/3G cellular, their costs and capabilities, and the special challenges involved in supporting mobile wireless applications.
