ISP REDUNDANCY

As Internet access becomes increasingly critical to business, the costs associated with loss of that connectivity become greater. To protect against network downtime it makes sense to deploy redundant systems for mission critical Internet applications. Connecting to the Internet via more than one Internet Service Provider (ISP) provides that additional redundancy.

A typical deployment with a single ISP link, and redundant deployment with duplicate ISP links is shown below.
