Enea is shipping a high-availability (HA) application framework for network equipment based on multiple operating systems. The framework supports Linux, along with RTOSes (real-time operating systems) such as Enea's proprietary OSE. It provides enhanced monitoring, fault detection, recovery, failover, load balancing, and management capabilities, Enea says.

According to Enea, the HA framework includes middleware that acts as a broker to notify the appropriate response agent upon events such as completion, fault detection, and more. The middleware includes a heartbeat monitor to periodically check the health of key system components, a fault recovery history for easy tracking of fault event sequences, and state aggregation facilities for monitoring collective system readiness, the company says.

Other key features listed by Enea include:

Pre-certification and verification for dynamic module loading
Hot system upgrades for whole or partial systems
Enhanced memory allocation and flow control to ensure optimal memory allocation and prevent messaging overflows
Performance balance monitoring for efficient load distribution across multiple processors
Polyhedra database back-up for system crashes

Mike Christofferson, director of product marketing at Enea, said, "Our high-availability middleware builds on [OSE's] baseline capabilities, providing enhanced fault detection, recovery, and management capabilities."

Per Åkerberg, Enea president, said, "Our new middleware [provides] a more highly integrated solution."

A 2003 VDC report on the embedded market ranked Enea sixth overall among embedded software providers. The company, which claims to be the world's second-largest provider of telecom RTOSes, began embracing Linux in April, 2004, since following up with a Linux port of its in-memory database, Polyhedra, the Orchestra SDK (software development kit) for Linux/OSE integration, and OSE AMP, an assymmetrical multiprocessing version of OSE designed to run alongside Linux on multiprocessor systems. Enea joined the Eclipse Foundation earlier this month, and is reportedly readying an Eclipse-based environment to compete with telecom RTOS leader Wind River's Eclipse-based Workbench 2.0 product.

Availability

Enea's Application Framework and IPC mechanism is available now for Linux, OSE, and other operating systems, with a minimal software configuration starting at $450,000.
