Wireless Network Infrastructure and Campus Network Trunking In Brief

A case study in Network Trunking
How can financial institutions effectively connect networks in buildings that are located in an urban campus environment?
• Victimized by success
Many financial institutions grow by merger and acquisition. This has the potential to rapidly expand the square footage required for operations by the successful organization. Many times, the expansion takes place in an inner city, where companies expand into adjacent building space. This is the urban corporate campus environment.
The challenge to IT planners is to provide high quality, high speed IT services to this urban campus, without busting the operating budget.

A case study in Convergence Toll-Bypass, Voice over IP, IP Telephony and QOS
How can financial institutions effectively leverage voice and data networking investments?
• Traditional Voice and Data Networking
Many financial institutions were built on legacy information systems. Many of these legacy systems used a proprietary communications system to connect users to the central processing units. One of the best known examples of this is IBM's' SNA (systems networking architecture). In the SNA architecture, the terminals, terminal controllers, communication links, front end processors and OS interfaces were all defined along with a communication protocol called SDLC. This was a completely proprietary data communications system and did not include provisioning for voice communications.

Solving the VPN Paradox

Deploying a comprehensive VPN solution without compromising network security
How can financial institutions effectively leverage voice and data networking investments?
• Don't believe the hype
In the past several years network equipment vendors sold a steady stream of Virtual Private Network (VPN) appliances with the promise of easy installation and quick return on investment (ROI). Although these claims have some validity, it is important to separate the facts from the marketing hype. For instance, it is mostly true that replacing dialup remote access solutions with remote access VPN saves a company from expensive toll charges. It is also mostly true that if your applications can tolerate the delay of the public Internet, then replacing dedicated circuits and other traditional Wide Area Network (WAN) links can save a company expensive recurring monthly telecommunication charges. Finally, it is true that VPN installations are quick and easy - as long as you choose the simplest possible design and ignore the more complex issues surrounding the technology.
