JetNexus Web Accelerator

jetNEXUS is a range of high performance, scalable, and robust appliance and software products that can transform the performance of your network infrastructure and therefore your business.

jetNEXUS Web Range Of Web Optimisers

The jetNEXUS web accelerator range consists of three core products designed from the ground up for high performance, high availability web environments.

They provide a robust front end for your web servers offering features such as SSL offload, compression, load balancing, connection management and full W3C logging.

Implementation is fast, simple and cost effective.

• jetNEXUS Web Accelerator
• jetNEXUS L7 Load Balancer
• jetNEXUS Integrated Application Accelerator

The jetNEXUS web accelerator uses the tried and tested jetNEXUS compression algorithm to deliver compressed optimised content in a form that is readable by the browsers.

Core Web Acceleration Platform Management Features

The advanced rule based that has been built up over the last 5 years ensures that if an object such as a base page or Java script is compressed the end user can render the page as normal.

Decompression is handled by the client browser (nearly every browser in use today has standardised decompression built-in), so no client plug-in is required and deployment is transparent to site visitors.

Most HTTP transmissions e.g. ASP, JSP, XML, CSS, JavaScript, DHTML, HTML, etc. can be compressed by up to 90% with a typical bandwidth reduction of 50% or more.

The jetNEXUS accelerator integrates into the jetNEXUS management platform and can run in conjunction with the jetNEXUS load balancer or/and the jetNEXUS SSL terminator.

Features of the JetNexus Web Accelerator

• Highly efficient acceleration algorithms ensure superb page delivery times while under significant load.
• Rule based compression detects and compensates for browser behavioural differences and defects, therefore guaranteeing accelerated pages can be displayed correctly by the client's browser.
• Supported by all standard web browsers and requires no client component.
• Browsers supported include MS IE 4.0+, Netscape 4.0+, Opera and Fire-Fox.
• Accelerate HTML, SHTML, DHTML, JHTML, PHTML, SOAP, J2EE, JSP, ASP, ASPX, CSS, Javascript, XML and more.
• Accelerate Office Documents (DOC, XLS, PPT, etc.) as well as configurable MIME types.
• Direct HTTP 1.0 and HTTP 1.1 Acceleration
• Can act on HTTP headers, POSTS, SOAP, HTML, JavaScript, etc.
• Accelerate HTTP 1.1 through HTTP 1.0 Proxies and Caches (e.g. Squid, MS ISA, etc.)
• Accelerate through Personal Firewalls
• Streaming Compression with full support for chunking
• Content Exclusions - by rule (e.g. /site sub-folder/*.js) or by header addedto specific pages
• Inline Content Substitution
• B2B acceleration between any two jetNEXUS appliances in a multi-point accelerator network including the acceleration of uploaded POST data (not just GETs)
• Web services (server to server) protocols including SOAP.

Who can use the JetNexus Web Accelerator?

jetNEXUS Accelerator can be used by e-commerce sites, corporate data centres, extranets, web hosts, service providers, as well as applications dependent on HTTP/ HTTPs services. It is platform-independent and applies high performance content compression to web services such as iPlanet/SunOne, WebLogic, Websphere, Apache and Tomcat (among others) along with their supporting database and application service environments.

JetNexus Web Accelerator Background

MS Internet Explorer and Netscape Navigator, since version 4, all have the ability to accept some level of accelerated content WITHOUT requiring a plug-in or other modification to the browser. Web servers on the other hand have themselves provided little or no direct support for this ability. jetNEXUS Accelerator provides the means to exploit this feature, and in doing so significantly improves the customer experience as well as providing considerable network benefits.

Once installation has taken place jetNEXUS will provide your business with an instant reduction in bandwidth requirement (directly proportional with the level of acceleration achieved). Your customers will experience improved page delivery times, so that both you, and your customers, will experience the benefits of jetNEXUS Acceleration.

As jetNEXUS Accelerator is a separate hardware device, there is no adverse effect on server resources (CPU and Memory Usage). Accelerator integrates easily into any infrastructure offering the instant benefits of compression without the requirement for user plug-ins, or changes to content.

The primary management interface for jetNEXUS Accelerator is a web-based console. The web console requires no special management software other than a standard browser. The interface is intuitive and easy-to-use. A basic configuration can be up and running within minutes. At the same time the web console is powerful enough to allow advanced configuration tailored to the requirements of a complex web site. The web console supports all of the advanced features provided by jetNEXUS Accelerator.
