A10 Networks, a San Jose, California-based vendor of application delivery controllers, has filed documents with US regulators for an initial public offering.

The number of shares or their price have not been determined. Morgan Stanley, BofA Merrill Lynch, JP Morgan and RBC Capital markets are acting as book runners for the offering.

The company plans to list shares on the New York Stock Exchange under the ticker symbol ATEN.

A10's products optimize IT infrastructure in a data center to improve application performance and availability. They also have security features.

The products are based on the company's Advanced Core Operating System (CORE), an application networking platform that optimizes processor cores and memory resources to increase application performance.

The platform's Shared Memory Architecture enables all processors to share common memory, minimizing communication between processors. This saves time because processors do not need to talk to each other and do not fight for allocated memory space.

In May of last year, A10 settled a patent lawsuit with Brocade, a San Jose-based vendor of networking gear, which accused it of infringement. A10 ended up settling for US$60m, according to a report by Ars Technica.

It is also fighting an infringement lawsuit over load balancing patents brought by Radware, an Israeli competitor.

The company's top stock holders are its founder and CEO Lee Chen, whose stake is about 21 percent, as well as venture capital firm Summit Partners and Japanese industrial giant Mitsui & Co.
