Wintegra is shipping a Linux software stack for its MIPS-based networking chips targeting D-SLAMs (digital subscriber line access multiplexers) and line cards. Wintegra Linux Services (WLS) includes data- and control-plane software and an application interface, and targets access equipment makers building low-cost, high volume devices.

WLS comprises:

• Data path software that has shipped in production volumes for three years, according to Wintegra
• An application interface or C-level calling structure known as WDDI (WinPath device driver interface), also in production for three years
• Newly launched DSL control plane software

The new control plane software is described as a high-level, object-oriented reference application that runs on top of WDDI. It supports the MIPS-based chips in Wintegra's WinPath chip line.

Wintegra has long offered Linux BSPs for its WinPath chip family, including drivers and hardware initialization code. However, WLS represents the company's first complete DSL application stack to support Linux, according to Cam Witt, director of product marketing.

“Demand for Linux is high in cost-sensitive, high-volume markets with short product lifecycles, such as Asia,” says Witt.

Availability

WLS is available now, priced at $35,000 with a command-line interface accessible through Ethernet or a serial console. A $50,000 version that supports SNMP (simple network management protocol) is also available. Both versions include support and training.
