Juniper Networks WAN Acceleration (WX/WXC)

The Juniper Networks WX platforms provide distributed enterprises with a cost-effective solution for accelerating applications over the WAN.

The WX/WXC platforms accelerate application performance for remote and branch office users accessing centralized resources, delivering faster response times, reducing WAN bandwidth consumption, and prioritizing mission-critical traffic to ensure uninterrupted business operations. The WXC platforms, which interoperate with each other as well as the Juniper WX application acceleration platforms, scale to meet a range of WAN bandwidth levels while providing a comprehensive feature set to optimize WAN performance.

Features

The WX and WXC platforms enable organisations to realise a range of business and technical benefits. With these application acceleration devices, enterprises can:

• Compression and Caching -The patented Molecular Sequence Reduction^TM (MSR^TM) compression and Network Sequence Caching technologies enable WX/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.

• TCP Acceleration - The WX/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.

• SSL Optimization - The Juniper WXC 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, they learn on the fly the key used by the client/server. This allows the WXC 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 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 and Windows and Linux file services improves application performance by accelerating their underlying protocols MAPI and CIFS, respectively.
  

• Application Control - The WX/WXC platform's Quality of Service (QoS) capabilities allow IT to assign priority and set bandwidth levels to ensure that business-critical and latency-sensitive applications such as Voice over IP (VoIP) always have sufficient bandwidth. The easy-to-use Juniper QoS implementation preserves QoS markings applied by other devices as needed and transparently map traffic onto carrier classes of service. 
  

• WebView and WX CMS Software - Visibility into and control over the WX/WXC platform is provided via embedded WebView device management and the powerful WX Central Management System^TM (WX CMS^TM) software. The WX CMS software provides visibility into application performance across multiple WXC and WX 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 platforms. To further reduce the delay associated with first-time downloads, WXC platforms implement content distribution that automatically push all new content to WXC 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.

Business Benefits

The WX and WXC platforms enable organisations to realise a range of business and technical benefits. With these application acceleration devices, enterprises can:

• Uninterrupted productivity - Accelerates mission-critical applications and rich content by reducing the volume of traffic.

• Confident interactions and transactions - Accelerates delivery of web applications by speeding application-specific protocols (TCP, UDP, HTTP/S, MAPI, CIFS).

• Real time collaboration and communications - Accelerates real-time business-critical applications, such as VoIP, by prioritizing and allocating bandwidth.

• Quick, secure access to the WAN - Accelerates features for secure applications, such as HTTPS, encrypted Remote Desktop Connections or CIFS with SMB signing.

• Proactive network and application traffic management - Provides the network and application visibility to deliver applications exactly as intended, on a consistent basis.

• Improved operational and cost efficiencies - Productivity gains the WX and WXC platforms provide in the form of application acceleration contribute to improving the bottom line.
