For those enterprises that have yet to implement WAN redundancy, the time will come, probably sooner rather than later, when it will become vital to do so. Mission-critical applications such as IP telephony (IPT), e-commerce, and remote access demand highly available, highly reliable WAN connectivity. This research note will address the following aspects of building WAN redundancy:
- Why enterprises would need redundant WAN connectivity.
- Methods to implement WAN redundancy.
- Costs and benefits of building highly available WAN connectivity.
Enterprises are increasingly becoming reliant on WAN connectivity, and the associated costs with downtime are likewise increasing. Consider the implications of any disruption in WAN connectivity, and take action to prevent costly outages.
