SSL Optimization

WXC Series’ 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’ 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’ 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 Software

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.
