By The Console Connect Team|24 June, 2019 ![Resized blog image - What does SD WAN mean for the future of MPLS](https://blog.consoleconnect.com/hubfs/Resized%20blog%20image%20-%20What%20does%20SD%20WAN%20mean%20for%20the%20future%20of%20MPLS.jpg) MPLS has been the de facto WAN technology standard since the turn of the century, providing organizations with a robust way of connecting their branch offices together and to more important sites like the corporate headquarters where the data center would reside. Optimal routing means MPLS can achieve very low latencies, and the fact that it is a private network bolsters the security. MPLS can also guarantee sufficient bandwidth and managed variation in latency (AKA “Jitter”) to ensure application performance. However, when it comes to new deployments, MPLS is a slow contender, with installations often taking several months to complete. It can also be prohibitively costly to deploy in remote, rural or low-traffic locations as it’s an expensive form of transport. This means that when it comes to capacity, many networks are under-provisioned from the start, or reconfigured on the fly, making for an intensely manual management process. The operations team tends to buy exactly what they need in terms of capacity over a multi-year term, without any form of buffer for future traffic demand. They will then use hierarchical application and service rules to ensure critical traffic is prioritized. [Learn to exploit the WAN for network orchestration with our e-book: **The Essential Hybrid Networking Guide**](https://cta-service-cms2.hubspot.com/web-interactives/public/v1/track/click?encryptedPayload=AVxigLI9Qi1LtHv6V17CcNd4KdOg2MABuzfbqEPlJ6ntMgtoYl%2FpPo5u%2BUmlLqyovjXoUr%2Bmp77Lj55OIKu0g2yVxVUzLHa47qQKhYgWfm9o2CbWG%2BR5otbPRmMw%2BQpXMUN1fwYD%2F04zbzClugc5pae9kSFalXRmLzt2j%2FblpdCztYanA3RRXIEyZ8PfdaGaPUqMDbxiuAbOGVbF%2BqCht3%2Fdq73i&portalId=3076203) ## The cloud introduces challenging dynamics The widespread adoption of public cloud-based applications and services has introduced a new and most challenging dynamic into the mix – the need for branch offices to connect directly to assets in the cloud. Although [MPLS](https://blog.consoleconnect.com/how-to-manage-networking-for-a-modern-enterprise?hsLang=en-us) is the workhorse of the [WAN](https://blog.consoleconnect.com/as-the-wan-becomes-more-critical-so-does-the-wan-provider?hsLang=en-us), it struggles to adequately support the highly accessible nature of the public cloud because it needs a pre-configured termination point and an end-to-end bandwidth management of the connection. This is easily done in the corporate data center and sufficed when heavy applications were all backhauled through a managed network to central site, but as the public cloud is owned and operated by other organizations, deploying appliances is not an option, and neither is managing the bandwidth on other organizations’ networks. Furthermore, the Trombone Effect also comes into play. There is little point in adopting SaaS applications to help your business agility if you end up hauling the traffic to and from your private data center through the internet. The variable latency and possible congestion may well wipe out any benefits. A [special study](https://www.businesswire.com/news/home/20170928006218/en/IDC-Survey-Finds-Bandwidth-Optimization-Consistent-App) from International Data Corporation (IDC) in late 2017 found that "bandwidth optimization", "consistent application security", "integration with existing WANs", and "improved automation and self-provisioning" were the top four motivators identified by respondents considering SD-WAN adoption (36 percent, 31 percent, 28 percent and 28 percent, respectively). “In parallel with the proliferation of cloud-based applications and services, the enterprise WAN is being rapidly re-architected to cost-effectively deliver new, secure capabilities," said Rohit Mehra, vice president, [Network Infrastructure](https://www.consoleconnect.com/services/network/) at IDC, in the study. ## MPLS remains critical infrastructure Yet the key here is that optimization and consistency are talked about in the same breath as integration with existing [WAN](https://blog.consoleconnect.com/productivity-gains-the-true-benefit-of-sd-wan?hsLang=en-us). This is because the consistent, optimized and critical nature of MPLS is still required and as such, MPLS is not going anywhere. “There's a huge popular perception out there that SD-WAN has killed MPLS,” according to [Nemertes analyst John Burke](https://nemertes.com/home-field-advantage-sd-wan-and-mpls/) in late 2018. “Our research consistently shows this to be untrue.” The analyst says that a large majority of organizations with MPLS plan to keep it even after they deploy SD-WAN. “Almost all of them have no goal of eliminating it. Most do plan on changing their relationship to MPLS, though. They may be capping spending on it. Or they may be going from a strategy of putting MPLS everywhere to only putting it in larger or more critical sites,” he said.
