The WXC product family consists of four members: the WXC 250,
the WXC 500, the WXC 590 and the WXC Stack.
WXC 250: The WXC 250 application acceleration platform features
a 40 GB internal hard drive, offers two copper 10/100 Ethernet ports,
and supports total reduction throughput speeds ranging from 128
Kbps to 2 Mbps. Designed for small to medium-sized branch office
applications, the WXC 250 platform supports up to 10 connections
to other branch office or data center WX or WXC devices.
WXC 500: The WXC 500 application acceleration platform includes
redundant 250 GB internal hard drives (for a total of 500 GB of
storage), two copper 10/100/1000 Ethernet ports, and support
for total reduction throughput speeds ranging from 512 Kbps to
20 Mbps. Designed for large branch office and small data center
applications, the WXC 500 platform supports up to 50 connections
to other branch office or data center WX or WXC devices.
WXC 590: The WXC 590 application acceleration platform features
redundant, field-serviceable 250 GB hard drives (for a total of 500
GB of storage), two copper 10/100/1000 Ethernet ports, and support
for total reduction throughput speeds ranging from 2 Mbps to 45
Mbps. Designed for data center applications, the WXC 590 platform
supports up to 140 connections to other branch office or data
center WX or WXC devices.
WXC Stack: The WXC Stack pairs up to six WXC 500 and WXC
590 platforms with a WX 100 to extend support for the Network
Sequence Caching function to 155 Mbps link speeds and up to
840 connected locations. In a full configuration, a WXC Stack can
provide 3 TB of internal storage capacity.
Features and Benefits
Compression and Caching
The patented Molecular Sequence Reduction
™
(MSR
™
) compression
and Network Sequence Caching technologies enable WXC
platforms to deliver up to a 100-fold increase in effective WAN
capacity, providing immediate congestion relief for all IP-based
traffic, including TCP- and UDP-based applications, while allowing
businesses to avoid costly WAN upgrades.
The MSR algorithm recognizes repeated data patterns and replaces
them with labels, dramatically reducing WAN transmissions and
improving overall application performance. Operating in memory,
the MSR dictionary can store hundreds of megabytes of patterns for
a broad cross-section of application types, from short chatty ones
to those with longer patterns. By eliminating redundant traffic, the
MSR compression technology delivers a 10-fold increase in effective
WAN capacity.
Sequence Caching is similar to MSR in that it identifies and replaces
redundant data patterns with labels before forwarding across
the WAN. However, Sequence Caching utilizes hard drives only
available on the WXC platforms to store larger data patterns over
longer periods of time, enabling the devices to detect and eliminate
repetitive traffic separated by gigabytes of data or last seen days or
weeks earlier. As a result, the Sequence Caching feature enables the
WXC platforms to produce up to a 100-fold increase in WAN capacity.
TCP Acceleration
The WXC platform’s Packet Flow Acceleration (PFA) technology
liberates data traffic from the limitations imposed by TCP,
increasing throughput across the WAN and accelerating applications
on low-bandwidth or high-latency connections between WX/WXC
platforms. Forward Error Correction (FEC), a component of PFA,
limits the need for retransmissions on “lossy” networks such as
satellite links by making use of recovery packets to reconstruct lost
transmissions.
