At Interop New York today, Citrix detailed its Citrix WANScaler 8000 Series, vaulting the vendor further into the bustling and crowded WAN optimization market.
The WAN optimization market has been experiencing solid growth over the past few years. Gartner Inc. said it expects the WAN optimization market to double by 2009, to more than $1.2 billion, and estimated that 55% of all employees worldwide will access their applications from branch offices.
WAN optimization tools such as WANScaler are important to network managers because they greatly decrease the time it takes files and applications to travel between headquarters and branch offices without the expense of increased bandwidth. Speedier transmission over the WAN also often translates to higher productivity and fewer hang-ups with slow applications.
According to Greg Smith, director of product marketing in Citrix's application networking group, WANScaler 8000 uses multi-level compression technology to boost application response time to branch offices over the WAN, while also reducing the need for often-costly bandwidth upgrades. The WANScaler series incorporates a new compression algorithm capable of compressing data at a 3,500 to 1 ratio. Smith said that the multi-level compression allows
In addition, the WANScaler 8000 Series adjusts among disk, level-two cache and memory-based compression and can support hundreds of branch offices, thousands of connections, and WAN throughput levels greater than 500 Mbps. Using those capabilities, a T-1 WAN link can support the equivalent of a Gigabit of application traffic while also improving the performance of applications to end users.
Added disk space can save more data for longer periods of time, Smith said, meaning that a file coming from headquarters to a branch can be saved at the branch. When the end user requests the document, a token is sent across the WAN notifying the branch office appliance to push the file to the user.
The 8000 Series features the WANScaler 8500 for medium and large branch offices, and the WANScaler 8800 for enterprise data centers.
Jimmy Chang, product marketing manager of Citrix's application networking group, said WANScaler reduces the need for networking pros to pay massive amounts of money to update the WAN, while also reducing the number of complaints the application team receives about slow app performance.
Along with the WANScaler updates, Citrix today announced the latest version of its Web application delivery appliance, NetScaler 7.0.
Built on the company's existing, Web-specific NetScaler line, version 7.0 features new capabilities for Web application delivery, such as application scalability, more powerful application policy management, improved application availability, expanded application security, enhanced ease of configuration and management, simplified SSL security management, and support for new application types.
