The types of technologies that can be used for network edge connectivity can broadly be separated into two groups: commercial-grade and high-grade WAN connection technologies. The distinction between the two has to do with available speeds, reliability, services, and cost. High-grade WAN connectivity technologies include Metro Ethernet and MPLS, while commercial-grade options include cable and xDSL. In this article, we examine the commercial-grade WAN technologies (cable and xDSL), how they function, and their most typical implementation scenarios.

With DaaS, you rent the equipment for a small monthly fee without having to pay anything up front, and the monthly payments count as an operating expense rather than as a capital expense. Offering a DaaS equipment rental program to your customers is a great way to provide equipment for companies who might not have the budget allocated to buy equipment, or who would prefer to account for the expense as an operating expense. In this article, we show you how you can easily offer a DaaS rental program to your customers.
