Juniper Polishes Redline App Acceleration

The company integrates its optimization acquisitions with its SSL VPN appliances and routers and adds a Web-based user interface.

Juniper Networks on Feb. 13 released a new version of the operating system for its WAN optimization/application acceleration appliances acquired last May along with Redline Networks.

Juniper in DXOS Version 5.1 delivers initial integration with its existing SSL (Secure Sockets Layer) VPN appliances and routers and adds a streamlined, Web-based user interface.

In the new Web interface, Juniper added a new Wizard for the softwares AppRules function, which allows the appliances to inspect content as it comes through the DX and modify the content based on defined rules.

"It lets you do things like resource cloaking, where you hide the back-end URL structure for the user and only present something simple," said Sean Tippett, product line manager for Juniper, in Sunnyvale, Calif.

The new Wizard allows users to create more customized rules without having to work with a text editor or command line interface. That makes it more accessible to mainstream users, Tippett said.

The upgraded operating system, which runs across all four models of the DX appliances, also rounds out their server load balancing capabilities with global server load balancing.

That allows enterprises with multiple data centers to route Web applications traffic to the data center best equipped to handle it. Using DNS (Domain Name System) algorithms, the global server load balancing function determines which data center can best respond to a request based on round-trip times and data center capacity.

DXOS 5.1 also adds the ability to set Quality of Service markings to prioritize critical business applications traffic over less critical traffic. The QOS markings can be enforced by Junipers routers and WX application accelerators.

"It allows the DX to prioritize an online store over a general browsing site, or give SAP or Seibel traffic priority over other more pedestrian traffic," Tippett said.

Juniper also broke out licensing for the product across four different levels of functionality, allowing users to deploy what they need, when they need it.

The four levels include a license for server load balancing and SSL termination; a license that builds on top of that HTTP/S acceleration, compression and TCP multiplexing; a license that adds advanced HTTP/S acceleration, AppRules adaptive content processing and 3G caching; and another that adds on global server load balancing. The licenses range from $15,000 to $70,000. The new release is due in March.
