transport for enterprise branch office users.

Solution Brief

Unified Communications Challenges

Unified communications is a business-critical application for companies of all sizes around the world. Assuring rich unified communications experience for all branch office users to collaborate is critical to maintain productivity and business agility. Delivering enterprise-class unified communications (UC) services over the wide area net-work (WAN) poses several challenges for both Enterpris-es and Service providers:

ɚ Large-scale deployment of UC is inhibited by expensive WAN bandwidth. Economical Internet links are widely available but are unreliable and difficult to support

ɚ Over-the-Top deployments suffer from poor UC user experience

ɚ Poor control and visibility of WAN links leads to perfor-mance and management problems

Integrated SolutionThe VeloCloud Cloud Delivered SD-WAN provides a solu-tion for Unified Communications including both VoIP and Telepresence, with Cisco for both:

ɚ Enterprise on-premises UC deployments

ɚ UC-as-a-Service (UCaaS) deployments by Cloud Ser-vice Providers

With this combined solution, enterprises gain the flexibil-ity and reliability to add Internet broadband and 4G/LTE circuits to their WAN for added capacity and resiliency. Unlike traditional hybrid networks, network sensitive UC voice and video streams can leverage all the available links and capacity yet be optimized to deliver quality end user experience. VeloCloud Dynamic Multi-Path Optimi-zation dynamically steers UC traffic across the optimal links and on-demand remediates common network deg-radations to assure business grade application perfor-mance. Per-packet steering and on-demand remediation capabilities are key to enabling UC traffic to reliably perform over hybrid WAN (private plus broadband), dual broadband and even single broadband WANs.

How It WorksDynamic Multi-Path Optimization is delivered by the unique combination of

three capabilities:

Continuous MonitoringAutomatic detection and monitoring of any attached WAN circuits provides a real-time assess-ment of WAN circuit capacity and performance profile including latency, jitter and packet loss on a uni-directional basis. This automates the provisioning of sites, as configurations don’t need to be manually adjusted on a site-by-site basis depending on the particular circuits available. The re-al-time performance profile also drives the Dynamic App Steering and On-Demand Remediation.

Dynamic App SteeringBased on the business priority and the current link conditions, recognized application flows are steered on a per packet basis to the optimal link or links. VOIP calls can be steered mid-stream without call interruption as brownout conditions are detected on any WAN link. High band-width UC video streams can be split across multiple links as well. Dynamic app steering enables sub-second reaction to any brownout or blackout occurrences as well.

On Demand RemediationIn addition to being able to steer around brownouts, if all links experience degradations concur-rently, or there is only one link available, then on demand remediation of packet loss or jitter can ensure the performance of UC applications.

Solution Details The VeloCloud Cloud-Delivered SD-WAN solution is deployed into existing WAN

architectures incrementally and with minimal disruption and risk.

The VeloCloud Edge is delivered as a virtual network func-tion that is deployed on the UCS-E module in the Cisco Integrated Services Router (ISR). The branch deployment is flexible and sites can be migrated incrementally:

ɚ Traffic can be dynamically and selectively forwarded into the SD-WAN overlay with dynamic routing. This provides a resilient design.

ɚ This capability can be added to some or all branch sites while maintaining full interoperability and con-nectivity between sites

ɚ Dynamic Multi-Path Optimization supports standard IPsec encryption for session privacy as well as dynamic branch to branch connectivity for optimal perfor-mance and scaling

VeloCloud Orchestrators and distributed Controllers provide centralized and resilient monitoring and manage-ment of the SD-WAN Edges. These components can be hosted by a service provider or deployed on premises by the enterprise as software components.

Enterprise UC DeploymentThe VeloCloud SD-WAN headend can be deployed in several ways for optimized performance. For smaller scale de-ployments, a virtual Edge on a Cisco ISR can serve as the enterprise hub, while larger deployments might leverage a standalone Edge as a hub. This could either be a virtual Edge or a pre-packaged appliance on a standard x86 plat-form. The Orchestrator offers tiered operator, partner and customer portals, each with multiple user roles.

UC Service Provider Deployment For UC cloud service providers, SD-WAN provides the ability to both deliver their UC application and assure applica-tion performance over the top of broadband enabled WANs. The broadband can be provided by the SP or by the cus-tomer in a Bring-Your-Own-Circuit (BYOC) arrangement. For the hosted UCaaS offerings, the service provider would install a multi-tenant virtual Gateway at their UCaaS cloud datacenters, as well as multi-tenant Orchestrator.

The VeloCloud Gateways enable the cloud service providers to also offer SD-WAN managed access to IaaS hosted applications as well. The Gateways can be provisioned with secure IPsec tunnels to Cisco carrier services routers (CSR) deployed in the IaaS datacenters.

BenefitsIn summary, the combined solution provides the following benefits:

VeloCloud Networks, Inc., the Cloud-Delivered SD-WANTM company, Gartner Cool Vendor 2016 and a winner of Best Startup of Interop, simplifies branch WAN networking by automating deployment and improving performance over private, broadband Internet and LTE links for today’s increasingly distributed enterprises.
