Unifying the Enterprise WAN, the Internet and the Public Cloud
Silver Peak Unity is a software defined wide area network (SD-WAN) fabric that unifies the enterprise network with the Internet and public cloud.
Unlike traditional WAN optimization solutions, Unity correlates information about cloud services and Internet “weather” to intelligently route traffic over a secure, optimal path.
By keeping SaaS and IaaS traffic on the Unity fabric, IT gains an ability it’s never had: the ability to monitor and control connectivity to the cloud while ensuring consistent SaaS performance.
Inside Unity Technology
- Advanced WAN Routing: Advanced Exterior Routing identifies the closest egress to cloud data centers and directs traffic to a cloud service over an optimal path, while Advanced Interior Routing dynamically selects the fastest, least-congested, or most available path for traffic by monitoring packet loss, latency, and bandwidth in real-time.
- Cloud Intelligence: This new subscription service delivers information about cloud services to Silver Peak software instances, creating an Internet weather map for intelligent routing decisions.
- Accelerated Encryption: The Unity fabric is built on IPsec VPN security without any performance degradation, using AES-256 encryption with SHA-1 authentication and a simplified deployment model.
- Data Reduction: WAN compression and deduplication inspects all traffic in real-time, eliminating repetitive transmission of duplicate data.
- Path Conditioning: Adaptive Forward Error Correction reconstitutes dropped packets in real-time while Packet Order Correction re-sequences packets that may traverse multiple paths across the network.
- Traffic Shaping: Applications are classified to prioritize critical traffic classes while constraining recreational or personal-use traffic classes.
- Global Visibility: Web-based GMS provides centralized orchestration of WAN deployments, advanced application classification, and detailed performance metrics.
How to Build a Unity Fabric
Silver Peak software installed in data centres, branch offices and cloud interconnection hubs generates the Unity fabric, a network overlay that controls and accelerates connectivity to any combination of enterprise services, IaaS resources and SaaS applications. Each Silver Peak instance on the Unity fabric communicates with Silver Peak’s new Cloud Intelligence service, which aggregates constantly changing information about cloud providers and Internet weather. Unity uses this information, along with calculations from each software instance, to dynamically route traffic to the cloud over the optimal path. Orchestration is handled by Silver Peak’s Global Management System (GMS), which provides IT managers with complete visibility and control over the deployment and use of cloud services.
