Redefining Enterprise Networking with SD-WAN

May 23, 2016

The wide area network (WAN) has proven itself invaluable for keeping globalworkforcesconnected and linking customers with the applications and data they rely on. However, its also proven to be a pain point in its own right, thanks to congested long-haul Internet links and the need for multi-protocol label switching (MPLS) and other slow-acting services.

Older technologies likeMPLSwere never meant for the near real-time needs of todays enterprises. As more applications are migrated to the cloud, global enterprises are clamoring for technologies that allow for faster connections and on-the-fly deployment, especially when the difference between success and failure for an enterprise can be measured in mere minutes.



The great thing about software-defined networking (SDN) is that the control and forwarding functions are no longer tied directly into the underlying hardware, taking much of the complexity out of networking while eliminating vendor lock-in. Networkadminscan also automate tasks that normally would have been done manually and even add and update software apps whenever necessary, all in near real-time.

However, there are a couple of bottlenecks that have a tremendous impact onSDN. The first is the fact that mostSDNvendors are selling forklift upgrades of their networking solutions instead of integratingSDNinto existing systems. This move often leaves enterprises locked into theSDNvendors solution, defeating one ofSDNsinherent advantages.

The second involves the WAN as a potential bottleneck in an SD-WAN setup. Unless the WAN is properly optimized, theres not much thatSDNcan do to advance network efficiency within the data center environment.

Shedding Legacy Services

Legacy services likeMPLSwere once powerful tools for enterprises. Even today,MPLSproviders still command a$25 billion worldwide market. Nevertheless, todays knowledge-based global businesses demand more responsive technology thats better suited for the cloud-enabled environment.

So how are these legacy services still holding sway over businesses? Many enterprises maintain existing long-term relationships with legacy vendors out of sheer inertia. After all, a contract renewal without any major changes seems easier to deal with than the uncertainty that comes with embracing change.

Sticking with the status quo could easily close the door on global expansion and a concerted push into the cloud.MPLSand other legacy services often lack the agility and flexibility for businesses to undergo beneficial changes quickly, such as opening up a new overseas location in the shortest amount of time possible.

The Promise of SD-WAN

The needs of todays global enterprises are straightforward — in addition to a global network that offers generous amounts of flexibility and agility, enterprises also want solutions where intelligence and security are not treated asadd-ons, but as integral pieces of the networking puzzle. The global enterprise also needs effective solutions that wont leave it vulnerable to vendor lock-in.

The SD-WAN stands ready to provide all of these features — no vendor lock-in, built-in network intelligence and security, and fast deployment times — all while providing users with access to all of their enterprise resources from virtually any location and with nearly any type of Internet connection. IP VPN,LTE, and business-class broadband connections can be consolidated into a single virtual WAN, giving IT personnel the power to effectively manage disparate links.

The SD-WAN offers the next step for any global enterprise looking to move forward. ContactQOS Networkstoday and learn more about how the SD-WAN can benefit your enterprise.
