Don’t let distance get in the way of Wget user agents and their targeted files. Silver Peak compensates for the increased delay and packet loss of the WAN. Wget downloads complete faster and require less bandwidth.
Wget is a popular program for retrieving content from Web servers. While generally effective, Wget struggles on high latency and congested wide area networks (WANs). The large amount of data Wget gathers through Web crawling takes longer to deliver to the client. SSL, which is often used with Wget, operates less efficiently.
Adding WAN bandwidth cannot solve the problem. TCP performance degrades as delay increases, regardless of bandwidth. Even when distance is nominal, delay may exceed expectations as a result of provider routing practices and peering policies, network congestion, and more.
Silver Peak tackles these problems, enabling a faster, more predicable Wget experience. Specifically, Silver Peak addresses the following challenges undermining Wget:
- Bandwidth – Silver Peak’s byte-level deduplication removes redundant Wget data from the WAN. More than 80 percent of Wget data can be typically removed from the WAN. The first time Wget 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 enabling Wget to operate more efficiently over distance. TCP Acceleration includes windows scaling, selective acknowledgements, and HighSpeed TCP. CIFS Acceleration includes CIFS read-ahead, CIFS write-behind, and CIFS metadata optimizations. Latency is also reduced 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.
- Congestion – Silver Peak makes Wget performance more predictable across congested WANs. Lost packets are reconstituted in real-time at the far end of a WAN link, avoiding delays that come with multiple round-trip retransmissions. Out-of-order packets are resequenced, avoiding retransmission and processing delays that occur when packets arrive out-of-order.
Silver Peak protects Wget data in-flight between locations with an Accelerated IPSec virtual private network (VPN) running AES-256, the enterprise standard for data encryption. Data-at-rest in Silver Peak instances is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.

This is a demonstration of Silver Peak VX virtual WAN optimization software accelerating remote file transfers (CIFS) between a data center and a remote branch office.
-
Users in branch offices and remote offices have traditionally had a difficult time accessing files stored in remote data centers. The Windows file system relies on CIFS/SMB a chatty protocol that performs poorly over the WAN. Silver Peak corrects CIFS chattiness, accelerating the transfer of data to the branch office or remote office. This document explains how Silver Peak enable centrally managed file services to dramatically improve branch office and remote office productivity.

Expansion fueled by acquisitions as well as organic growth drove Donegal Insurance Group to modernize its data center. The effort, which was well along by early 2009, included server virtualization and an enterprise-class storage area network. Mike Clement, Donegal's assistant VP for information services, says the SAN helped ensure business continuity by replicating data between the Marietta, Pa.-based insurer's main data center at its headquarters and its distant disaster recovery (DR) site in Le Mars, Iowa, but bandwidth was becoming scarce.

Prudential Investment Company Australia (PICA) has improved security, achieved backups that are five times faster, and is saving $5,000 a month on bandwidth costs it no longer requires. All achieved by implementing Silver Peak WAN optimisation software. With more than 500 staff at 25 locations from Port Douglas to Melbourne, PICA generates substantial amounts of critical data. When Technical Services Manager Neal Krempin joined PICA, he found that hourly backups between the company’s data centre site in Ultimo, Sydney, and the disaster recovery (DR) site in Port Melbourne often failed to complete on time, exposing the company to the risk of serious data loss.
