Real-time applications improve business velocity, but as distances grow and the effects of network congestion take hold, their performance suffers. Stock or data updates take too long to occur. Virtual desktops feel sluggish. Video and audio become unusable. Silver Peak eliminates or reduces the effects of network congestion and of latency that degrade real-time performance. With Silver Peak, your real-time application can continue to deliver the optimum experience even over long distances or erratic networks.
Real-time systems and applications, such as commodities trading, some e-commerce systems, and instant messaging, must operate within a defined window of time. As such, operating over distance becomes a problem for many of these applications.
It’s not just the natural delay that’s incurred as distances grow. Traversing a service provider’s infrastructure, coupled with the effects of network congestion, particularly in the Internet, often limit the scope of a real-time application. And when they are delivered to a remote office, real-time applications remain highly susceptible to the outages and failures in the Internet and service provider networks.
Silver Peak addresses all of those issues, improving the availability of real-time applications while eliminating or dramatically reducing the delay that might interfere their operations. Every Silver Peak instance dynamically determines the optimum path across any network for a real-time application. Multi-homing offices to private networks, such as an MPLS service, and Internet services, lets Silver Peak select from a greater range of paths, making the real-time application more resilient to outages or slowdowns in any one path.
And along any given path, Silver Peak corrects the underlying problems that might disrupt real-time application:
- Congestion – Silver Peak minimizes the effects of network congestion, making real-time application, such as VoIP, more predictable across congested WANs. Packet loss is reduced by as much as 90 percent, or eliminated entirely, by regenerating packets in real-time at the far end of a WAN link. Out-of-order packets are resequenced, avoiding retransmission and processing delays that occur when packets arrive out-of-order. Quality of Service (QoS) and traffic shaping guarantee real-time applications receive the necessary bandwidth. The culmination of those capabilities has been shown to practically eliminate 120 msec of jitter and one percent packet loss from a connection, dramatically improving voice and any real-time application running across the connection.
- Bandwidth – Silver Peak byte-level deduplication eliminates redundant data across the WAN, making more bandwidth available for real-time applications. The first time an application sends data it is fingerprinted and compressed by Silver Peak. Subsequent requests are fulfilled by the local Silver Peak instance.
- Latency – Silver Peak mitigates latency of TCP-based applications with TCP Acceleration, which includes windows scaling, selective acknowledgements, and HighSpeed TCP and CIFS Acceleration, which includes CIFS read-ahead, CIFS write-behind, and CIFS metadata optimizations. Latency is also reduced for all applications through packet coalescing, which re-packages multiple smaller packets into a single larger one, and through Dynamic Path Control, which selects the fastest path to a remote location.
Silver Peak protects the files and data used during a video conferencing collaboration in-flight between locations with an Accelerated IPSec, virtual private network (VPN) running AES-256, the enterprise standard for data encryption. Data-at-rest within Silver Peak instances is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.
Silver Peak offers the most scalable and cost-effective data acceleration software for connecting data centers, remote offices and the cloud. You can download and deploy it as a free, self-service trial in just 20 minutes or contact us to see how Silver Peak can help your organization.

Panasonic turns to Silver Peak for Real-Time Global Design Collaboration
Most major enterprises have Voice over IP (VoIP) projects either under way, or in the testing and evaluation stage. According to a recent ComputerWorld survey, VoIP deployments will grow faster in the next 18 months than any other category of enterprise applications, with a full 16% of enterprises planning to implement VoIP in that time period.
Silver Peak’s WAN optimization solution helps enterprises reap the rewards of virtualization by overcoming network challenges that impact the performance of these applications across the WAN. More specifically, Silver Peak addresses latency, packet loss, and bandwidth challenges that cause virtual applications (for example, Citrix XenApp) and Virtual Desktop Infrastructures (for example, Citrix XenDesktop, Microsoft Desktop Virtualization, Sun Ray, and VMware VDI) to be unresponsive and/or unreliable across the WAN.
Shared Wide Area Networks (WANs), like MPLS and Internet VPNs, are prone to network congestion during periods of heavy utilization. When different traffic is vying for limited shared resources, packets inevitably will be dropped or delivered out of order, a concept known as “packet loss”.
