Juniper's Open Cloud Interconnect: There's More to DCI than Turning Up Wavelengths
Mar 21, 2017

Across the globe, network operators are prioritizing capital expenditures that help build a better cloud business. Service providers are redesigning network architectures in line with the telco cloud concept. Hyperscale internet content providers are expanding their data center footprint. Enterprises of all shapes and sizes are adopting private and hybrid cloud strategies.

 

One of the foundational requirements to drive cloud businesses forward is data center interconnect (DCI) designed and optimized to the operator’s cloud services portfolio, enabling operational simplicity and unconstrained innovation—the ability to open up and disaggregate DCI transport so operators can move at the pace of the cloud.

 

With today’s announcement of Open Cloud Interconnect, Juniper accelerates our customers’ cloud businesses and redefines the market for DCI solutions.

 

VERSATILE ARCHITECTURES

Open Cloud Interconnect provides operators the versatility to interconnect data centers with a combination of high-capacity coherent optics and DCI-optimized switching, routing, network control, security and virtualization technologies—all in an open, programmable environment unconstrained by operational silos, vendor lock-in, and interoperability challenges.

 

In contrast to many vendor approaches, Open Cloud Interconnect is not just about activating wavelengths between two points. It is about delivering the right mix of routing protocols and tunneling, coherent optical transport, open API’s and software solutions driving superior performance of cloud content, services and applications.

 

With Open Cloud Interconnect, Juniper provides comprehensive visibility and control of DCI networks, addressing any cloud business use case for any type of data center operator.

 

How is this possible? By having the versatility to define DCI from the data center edge or from the spine, and providing the option to either integrate coherent optics into the router or switch or connect over gray optics to standalone optical DCI platforms. 

 

DCI from the Data Center Edge

MX Series routers enable operators to define a dedicated segment of an IP backbone specifically for DCI. MX delivers proven advantages in traffic engineering, predictable QoS, high availability and scalability, whether the network is based on Layer 3 VPN or EVPN, which is increasingly preferred for DCI because of its support for Layer 3 and Layer 2 workloads, efficient use of capacity leveraging BGP, and active-active multi-homing with load balancing.

IP Overlays from the Spine

For enterprises and many cloud service providers where simple, cost effective DCI is the main goal, an IP overlay network from the data center spine layer is often the optimal approach. Leveraging the Q5 ASIC, QFX10000 switches deliver superior EVPN scale and performance in distributed cloud environments and can also support unicast VXLAN deployments.

Supporting these use cases are new coherent DWDM modules for the QFX and BTI series and a new suite of services that help our customers plan, build and optimize DCI networks.

 

UNCONSTRAINED INNOVATION

Data center operators face the critical challenge of driving network innovation with the required speed and agility to meet cloud services demand. Increasingly, to reach this goal network operators see open, disaggregated architectures as a path forward.

 

One of the main ideas behind disaggregation is to deploy coherent transponders independently of the optical line system so innovation can occur rapidly where and when the operator needs it—without the constraints of vendor lock-in and interoperability barriers.

 

Open Cloud Interconnect provides operators with multiple ways to build DCI networks, including over open and disaggregated optical transport. Open Cloud Interconnect is proven to interoperate with third-party optical line systems—and open line systems—and supports open APIs for easy integration into SDN-based network controllers and applications.

 

At the OFC conference in Los Angeles this week, Juniper will host and participate in several events demonstrating line-side interoperability. Among them is a readout of a recent test with Microsoft, where Juniper supplied its QFX10000 Coherent DWDM Line Card to prove interoperability of 150G and 200G coherent wavelengths over an open line system.

OPERATIONAL SIMPLICITY

As cloud networks become increasingly distributed, data center operators face operational complexity on several fronts, including in DCI. Juniper Open Cloud Interconnect meets this challenge head-on by collapsing operational silos where practical and by making bandwidth activation quick and easy.

 

For operators integrating coherent optics into the MX or QFX Series, Junos Space software establishes one control point from the photonic layer to Layer 3—an ideal solution for customers with consolidated packet and optical operations. If the customer prefers a management and control solution dedicated to the optical layer, Juniper’s proNX Service Manager can now support any coherent DWDM interface on the PTX, MX, QFX and BTI Series products, making possible cross-portfolio optical activation and monitoring.

 

Simplifying operations further are the new line cards for QFX and BTI Series. The QFX10000 Coherent DWDM Line Card offers 1.2 Tbps of easily configurable DCI bandwidth in a low-power, single-slot footprint. The UFM6 muxponder for the BTI7800 line delivers high-density coherent DWDM and creates a simple, pay-as-you-grow architecture enabling incremental scale with minimal initial investment.

 

Contrail Networking and NorthStar Controller

Automation is key to simplifying DCI operations and will play an increasingly important role in driving opex efficiency and enabling seamless coordination between the network resources inside the data center and in the DCI network. For operators implementing an Open Cloud Interconnect solution, Contrail Networking and NorthStar Controller can drive automation of network configuration, cloud service delivery, and resource optimization. Stay tuned to this blog for more on this topic in the weeks and months to come.
