Pronto Systems Announces Open Switch Software Architecture

Pronto Open Switch Software Architecture (OSSA) provides the ultimate software flexibility and manageability to the data center network.

Palo Alto, Calif., April 18, 2011 ā€“ Pronto Systems, Inc., a data center networking start-up, announced today its Open Switch Software Architecture (OSSA) which aimed to provide an open software environment to increase the flexibility and manageability of data centers.

OSSA leverages open source uBoot as the boot loader and Linux as its operating system. “By going with Linux, we provide an open environment for users and programmers to extend the manageability of the switches by installing and programming their own management modules. ” said Lin Du, CTO of the Pronto Systems, “Linux also provides the strong security and rich support tools that would help the data centers to manage and monitor the infrastructure.”

OSSA incorporates two major software engines, Xorplus and Indigo, into its protocol management. The Xorplus protocol engine provides rich L2/L3 protocol sets, including STP/RSTP/MSTP, LLDP, LACP, OSPF, RIP, PIM, and IGMP, with lifetime free license. Xorplus also supports both IPv4 and IPv6 for future-proof data center network.

The Indigo engine, an open source program developed by Stanford University, provides a new programming interface for users to manage the switches through OpenFlow controllers.

“We are excited to see OSSA emerge as an option for enterprise customers looking to leverage open standards, implement new features and deploy network virtualization in the enterprise with OpenFlow” said Guido Appenzeller, CEO of Big Switch Networks.

Besides the supported software, users can also use the GNU toolset to program, troubleshoot, and manage the switch with their own proprietary software. This provides the ultimate flexibility to the data center users.
