How can I determine which router to purchase based on port density and throughput ? I need to terminate two 45mbps ethernet connections into the router. A primary and 2ndary connection. The ethernet connections connect our office with two data centers about 2 miles away from the office. I will be doing file transfers over the lines that will approach 40 mbps of utlization. What is the lowest end router I can purchase that has the processing power to pass this amount of data ? The lines are active standby so the router will only be passing data over one of the links at any given time. This is a copper connection through the Cox network. A Metro Ethernet type situation if you will.
