F5 jams new tools into traffic manager

The many new mechanisms to secure and speed up applications running on networks are heading for consolidation that should make it easier and less expensive to deliver the kind of performance end users want.

F5 Networks next Tuesday plans to bring this integration to a new high with the next generation of its Big-IP software platform, which will pack traffic compression, denial-of-service attack protection and other features into a variety of new server load balancing devices as well as some older F5 boxes. The company, a pioneer vendor of application traffic management hardware, which handles the performance of applications over a network, aims to stop the proliferation of separate appliances and accompanying software interfaces.

That's a worthy goal, according to industry analysts.

"Every time there's ten new products out on the market, you end up with ten boxes on your network," said Joel Conover of Current Analysis, in Sterling, Va. Consolidation is natural, he added. "All these products get perpetually integrated down into these Web load balancers," he said.

A Big-IP platform acts as a front end to an array of servers, balancing the load of user requests to those servers as well as giving each user session the right characteristics and securing the network, according to Jason Needham, senior product manager at F5, in Seattle. It includes content acceleration, connection optimization, traffic compression, rate shaping, denial-of-service attack protection, Secure Sockets Layer (SSL) encryption and an application firewall. Each enterprise can tune the software to best serve its own applications, he said.

As enterprises make existing applications accessible via the Web, they will have to keep delivering the performance that end users have come to expect, said analyst Jarad Carleton of Frost & Sullivan, in San Antonio, Texas. The functions built into the Big-IP platform should help them deliver that, Carleton said.

Bringing those functions together into a single box with one operating system and user interface can save money on hardware as well as management time, analysts said. But in some cases it may also be the only way to carry them all out, because encryption has to be coordinated with other functions or they won't work, according to Lynn Nye, president of APM Advisors, a consultancy in Portland, Ore.
