Data Reduction

Compression and Deduplication Contribute to Superior WAN Performance

At the heart of Silver Peak's WAN optimization heritage is data reduction capabilities. Silver Peak WAN compression and deduplication inspects all traffic in real-time, eliminating repetitive transmission of duplicate data.

Silver Peak data reduction inspects all inbound and outbound WAN traffic in real-time, storing a single local instance of data on each Silver Peak appliance. Short reference pointers are used to deliver repetitive information locally, eliminating the transfer of duplicate traffic over the WAN. If content is modified, the Silver Peak devices will detect the change at the byte level and update each device’s Network Memory accordingly. Only the modifications are sent across the WAN, improving scalability and response time. The end result: you get much more efficient bandwidth usage and LAN-like application performance over the WAN.

Data Reduction Improves WAN Performance

Data Reduction Improves WAN Performance


  • Works on all IP traffic. Addresses any transport protocol or application version.
  • True byte-level granularity.
  • Minimal insertion latency. Network Memory is ideal for real-time and interactive traffic
  • No risk. Will not break current or future applications or corrupt data.


  • Lower telco and cloud costs. Avoid or delay costly WAN bandwidth upgrades by eliminating over 95% of WAN traffic. Lower cloud costs by over 50% by reducing data being transferred.
  • Move data quicker between data centers, branch offices, remote locations and the cloud.
  • Improve performance of centrally hosted storage and applications.
  • Ensure success of strategic IT projects that rely on the WAN, like data replication, data center consolidation, virtualization, cloud, and big data.
