The premise of the research is that both IP VPN and Ethernet WAN services offer enterprises a range of technology and business benefits and perform best when deployed in environments that closely match their capabilities. The paper first examines the major differences between an Ethernet WAN and a network-based IP VPN and then discusses the benefits and advantages of the two technologies. Typical examples are then reviewed of when it is best to use a network-based IP VPN solution, an Ethernet WAN solution, and a combined hybrid IP VPN/Ethernet WAN solution based on different enterprise requirements.
