IP WANs overtake proprietary technologies
For quite some time IP networks have been the technology of choice for LAN’s. It was thought to be totally inconceivable that IP based networks would overtake proprietary technologies such as ATM and Frame Relay for wide area networks (WANs). However, that is exactly what has happened.
There are a plethora of decisions to be made on how to deploy an IP based WAN and various technologies that have the potential to meet the many and varied requirements. Should you wish to deploy a layer two or layer three network there are a number of questions that need to be answered:
● How do IP Sec VPN and SSL VPN fit in?
● Is it necessary to implement MPLS?
● Do you move over in a phased approach or does it have to be ‘big bang’?
