1. REDUNDANCY - Broadband Dr. John P. Abraham Professor UTPA

2. This slide series is a summary of what we discussed in class. Power Broadband Hard Drive Backup Cluster

3. Broadband redundancy Determine highest speed you would need and that should become your primary broadband. Determine the lowest speed you can get by without damaging your business much, make that your secondary broadband. Both services should provided you with pool of public IP addresses. Assign one of those IP addresses to appropriate router or modem. In case of a modem the public IP should be passed on or bridged to the load balancer discussed below.

4. Redundancy and load balancer Purchase a router that is capable of load balancing. All Private LAN traffic should go through this router. A load balancer will have more than one WAN port. Assign appropriate public IPs to each of the WAN. Appropriate means the IP address should come from the appropriate service connected to the WAN port.

5. Stand by WAN service If the primary fails then the secondary should take over

6. Load balancing If either the download speed or the upload speed is similar you may want to load balance. Set appropriate policies for load balancing. For example, you may want to set a policy for secure connections to go through a designated WAN.
