Top to Bottom Success in the Enterprise WAN

Routing the Enterprise Journey

Multicloud has changed the world, and as much as the transition is impacting the inside of the modern data center, it is reshaping the networks between them. In championing the migration to multicloud through 2018, Juniper Networks saw growing momentum for our Contrail Enterprise Multicloud and Contrail SD-WAN solutions. Given the heavy focus in the industry on automation and overlay (commonly known as SD-WAN), the underlying network (commonly known as Enterprise WAN) is often overlooked. Juniper has been delivering solutions for Enterprise WAN across private and leased networks that enables a secure, reliable and scalable network underneath SD-WAN.

Today, we published the enhanced Enterprise WAN 5-step journey, along with leading thinking about the evolution of routing and securing enterprise networks under the sweeping forces of multicloud. So let’s peel back the SD-WAN overlay and see how  enterprise customers are securing and automating their Enterprise WAN with Juniper Networks solutions in four key areas: WAN backbone, data center interconnect (DCI), public cloud and internet peering.

Enterprise WAN

Juniper Enterprise Multicloud Routing Top to Bottom

Hastily jumping into public cloud or proprietary data center solutions can encumber enterprises as they move to multicloud. With multicloud squarely in Juniper’s enterprise strategy, our goal is a future where enterprises are free to move workloads between clouds with optimal networking and strong security in the overlay and underlay networks—top to bottom. Overlays and underlays are well understood in the data center, but in the WAN, examining and optimizing the underlay for the new multicloud era is not well covered, nor well understood.

Starting at the bottom in the WAN underlay or transport, Juniper’s strength in WAN routing technology and vision is built on a foundation that helps enterprises connect their campuses, data centers and the super-highway of direct connections into public cloud with SDN-based traffic engineering using NorthStar, switches, and routers like the MX10003, MX204, QFX10000 and PTX.

On top in the WAN overlay, solving the difficult challenges upfront, Juniper purposely built Contrail SD-WAN to conquer NFV, uCPE and SD-Branch. We are now the provider of the most scalable and versatile secure SD-WAN solution, while other vendors in the space are fettered with architectural revamps to try to add in branch security and LAN orchestration. Best of all, our open standards-based solution bridges seamlessly with WAN backbone routing used in the underlay or traditional multi-vendor routing.

Juniper’s portfolio easily serves the largest enterprises that need to direct the WAN backbone and other underlay routing use cases. It also serves enterprises, big or small, looking for SD-WAN control. And unlike some SD-WAN vendors, Juniper acknowledges and addresses WAN solutions top to bottom. Furthermore, the WAN overlay solution is only complete with solid SDN overlay control for the data center interconnect (DCI).

New in Multicloud DCI

SDN inside the data center was easily the first major use case for more dynamic software control over scale-out switching architectures and plugging into workload orchestration systems. Other use cases found in a DCI involving secure underlay. This could be over internet with IPSEC, over dark fiber with MACSEC and simple DCI.On top of the secure underlay, EVPN gives you the ability to achieve large scale multi-tenancy and workload mobility. Contrail Enterprise Multicloud handles the data center top to bottom, managing the physical underlay fabric, virtual overlays, and security and can plug into a range of workload orchestration systems. 

To bridge the SDN journey between data centers in the WAN, we have now expanded Contrail Enterprise Multicloud for overlay control with standards-based EVPN-VXLAN type 5. The solution to orchestrate L3 DCI is available today and supported with our MX and QFX Series devices.

The new DCI features naturally complement the Contrail Enterprise Multicloud solution inside the data center, and round out our SDN orchestration for enterprises end-to-end and top to bottom. 

Multi SDN

The Enterprise’s Reach Should Exceed Its Grasp

Enterprises of all sizes need to plan their journey to a multi-vendor multicloud reality because change is inevitable but network rip-and-replace disruption is not. To this end, Juniper has put together the latest 5-step enterprise WAN journey to secure and automated multicloud.

As enterprises are advancing their multicloud routing and WAN to develop SD-WAN, DCI, multicloud transport routing and SDN optimization, Juniper Networks' building blocks and commitment to open standards can maintain smooth growth with an evolvable architecture.
