If you are about to renew your MPLS contract, or if you need to upgrade your capacitySTOP! Dont commit to another year of MPLS until youve had time to consider if its the right technology to carry your business forward. Modern enterprises now have alternatives to MPLS that are more flexible and just as reliable for building a WAN.

In short, SD-WAN aims to remove the constraints of legacy connectivity technologies, namely MPLS and the unmanaged public Internet , ushering a new age of flexible, resilient and secure networks. As such, SD-WANs impact on the substantial ongoing IT investment in MPLS is limited. Enter SD-WAN.

Unless you were living under a rock, you probably heard about SD-WAN and its promise to transform enterprise networking as we know it. And, by enterprise networking we mean the use of MPLS at the core of enterprise networks. So, to SD-WAN or to MPLS? The MPLS architecture and its guarantees are now under pressure.

Its become the favorite whipping boy of networking. Since the early days of the Internet, routers were shaped by a myriad of technical constraints. General purpose processors lacked the processing power, forcing router vendors to rely on custom hardware. MPLS services are not the answer. The Internet is erratic.
