Silver Peak provides a robust WAN optimization solution that addresses the bandwidth, latency, and packet loss issues that are common to most enterprise environments. Silver Peak's optimization techniques are all performed in real-time and primarily at the network (IP) layer to ensure maximum performance across the widest range of applications and WAN environments.
Silver Peak appliances leverage the following Virtual Acceleration Open Architecture (VXOA) technology components to accelerate all enterprises applications in a secure and reliable fashion:
Network Memory: Silver Peak's patent-pending solution for disk based WAN deduplication. Network Memory inspects all traffic that is sent between clients and servers, storing information as a local instance in Silver Peak appliances. Repetitive information is delivered locally rather than sent across the WAN, improving application performance and WAN utilization. Cross-flow payload and header compression provide additional gains on first-time data transfers and non-repetitive traffic.
Network Integrity: Silver Peak employs a variety of real-time techniques to address packet delivery issues common to shared WAN technologies, such as MPLS and IP VPN. These include adaptive Forward Error Correction (FEC) and Packet Order Correction (POC) to overcome dropped and out-of-order packets, and advanced Quality of Service (QoS) techniques to prioritize traffic and guarantee network resources.
Network Acceleration: Silver Peak mitigates the impacts of latency across the WAN by using various TCP acceleration techniques, like adjustable window sizing and selective acknowledgements, as well as CIFS acceleration techniques, such as read-aheads and write-behinds. These tools help to overcome inherent chattiness that can otherwise hamper application performance across a WAN
Secure Content Architecture™: Silver Peak keeps enterprise data secure with its Secure Content Architecture. All NX appliances are equipped with hardware based AES encryption to protect local data stores. Optional IPsec keeps content safe when it traverses the WAN. Intelligent security policies can be established for granular control of WAN traffic.
