SSL Optimization
WXC Series platform’s SSL acceleration capabilities provide SSL
encrypted applications like Web-based (HTTPS), mail (imaps/
pop3s/smtps), and directory services (LDAPS) with the same
performance benefits as unencrypted applications. Once the
applications’ certificates and private keys are installed on the
WXC Series, they learn on-the-fly the key used by the client/server.
This allows the WXC Series to read the flow decrypted and apply
all its different optimizations like compression and caching or
application acceleration. To enhance security, the traffic moving
between the WXC Series platforms can be encrypted using an
IPsec tunnel to ensure privacy is retained.
Application- and Protocol-Specific Acceleration
The Application Flow Acceleration (AppFlow) technology
improves the performance of specific applications and protocols
– including Microsoft Exchange, Windows file services and Web-
based applications – over the WAN.
AppFlow for Microsoft Exchange, Windows, and Linux file services
improves application performance by accelerating their underlying
protocols – MAPI and CIFS, respectively. These protocols send data
in small blocks that must be received and acknowledged before
the next block can be sent, requiring hundreds or even thousands
of round trips to complete a single transaction. The AppFlow for
Microsoft Exchange and AppFlow for CIFS technology, pipelines
these data blocks in quick succession, delivering up to a 50-fold
improvement in application performance, meeting the needs of
remote and branch office users accessing centralized applications
or Network Attached Storage (NAS) data over the WAN.
AppFlow for HTTP accelerates Web-based applications over
the WAN by enabling the WXC Series to learn and cache objects
associated with URLs. Similar to MAPI and CIFS, HTTP submits
a series of sequential requests for Web objects, requiring tens or
hundreds of round-trips between the client and server to build a Web
page. With AppFlow for HTTP, the WXC Series platform transparently
caches objects locally, resulting in much faster page loads.
Application Control
The WXC Series platform’s QoS capabilities allow IT to assign
priority and set bandwidth levels to ensure that business-critical
and latency-sensitive applications such as VoIP always have
sufficient bandwidth. The easy-to-use Juniper Networks QoS
implementation preserves QoS markings applied by other devices
as needed and transparently map traffic onto carrier classes of
service.
In addition, a congestion control feature that tightly couples the WXC
Series platform’s QoS engine with the MSR compression technology
allows QoS policies to dynamically detect changes in bandwidth
availability and adjust allocation and prioritization schemes
accordingly.
The WXC Series also offers a Policy-based Multipath feature
which enables IT to assign applications to a specific path in
locations served by multiple WAN links. The WXC Series monitors
loss and latency characteristics on each link and automatically
diverts applications to the alternate path if performance falls
below acceptable levels.
WebView and WX CMS Soware
Visibility into and control over the WXC Series Application
Acceleration Platforms is provided via embedded WebView device
management and the powerful WX Central Management System
(WX CMS) software. The WX CMS software provides visibility
into application performance across multiple WXC Series devices,
enabling extensive configuration, monitoring and management
capabilities. Individual device monitoring and configuration can be
performed via WebView device management or a command- line
interface (CLI).
Content Distribution
Content distribution and WAN optimization are now integrated
on the WXC Series. To further reduce the delay associated with
first-time downloads, WXC Series implements content distribution
that automatically pushes all new content to WXC Series devices,
proactively “warming” the cache and pre-populating the hard
drive with data patterns to optimize every download. This content
distribution can be managed in a single location with the WX
CMS software, where the distribution can be pushed to multiple
locations, scheduled in advance, executed once or repetitively to
ensure that all branch offices maintain the highest performance.
Easy Installation and Configuration
WXC Series platforms can be installed and configured in just 10
minutes using a Web-based installation wizard. Configuration can
also be fully automated using the WX CMS software. IT simply
defines centralized configuration templates; when remote WXC
Series devices boot up, they retrieve a network address, locate the
WX CMS software server through the domain name service (DNS),
download their configuration file and/or specified software, and
begin operation.
The WXC Series also supports redundant configurations to ensure
complete fail-safe operations. In the event of a failure, the WXC
Series automatically converts to bypass mode, allowing traffic to
pass through untouched.
Transparent to other network equipment, WXC Series can be
installed directly inline between a LAN switch and WAN router,
or they can be deployed offline by attaching to an available port
on the switch or router. The WXC Series also works effectively
alongside VPN servers, firewalls, and other security devices, where
they optimize traffic before it is encrypted.
