Providers Moving to MontaVista Linux Carrier Grade Edition for Commercial Off-the-Shelf Applications
In recent years there has been a sea change in the way network equipment providers (NEPs) develop their network infrastructure applications. For years the telecom industry had been using proprietary hardware solutions with proprietary carrier-grade real-time operating systems (RTOS), often built in house. But now the industry has moved away from RTOS and is focusing on carrier-grade Linux as the development platform of choice for commercial off-the-shelf (COTS) applications.
The emergence of Linux as the most attractive option is not only because it provides the required carrier-grade availability and functionality, but also because it can greatly increase time to market while reducing development cost and risk. By purchasing a carrier-grade Linux development platform off the shelf, carriers can save the cost and effort of developing a proprietary development platform, which could easily amount to more than half of the required development effort, and instead focus on value-added applications and software.
MontaVista is the undisputed leader in the carrier-grade Linux market, with leading global carriers and device manufacturers, including four of the world's top five NEPs using MontaVista Linux Carrier-Grade Edition (CGE) for their carrier-grade products. MontaVista is also active in a number of carrier-grade standards, and CGE 4.0 is compliant with the major carrier-grade specifications.
Compliance with Carrier-Grade Specifications
MontaVista Linux CGE enables the Advanced Telecom Computing Architecture (ATCA) market. ATCA is a carrier-grade communications equipment specification developed by the PCI Industrial Computer Manufacturers Group, and MontaVista Linux CGE is the chosen Linux for ATCA.
MontaVista is also an active participant in the specification process for CGL, a carrier-grade specification promoted by The Linux Foundation (formerly OSDL), and MontaVista Linux CGE 4.0 is CGL 3.2 compliant.
Another important body is the SCOPE Alliance, a consortium of network equipment vendors founded by Siemens, Alcatel, Ericsson, Motorola, NEC, and Nokia whose mission is to accelerate deployment of open standards-based carrier-grade platforms. Montavista Linux CGE 4.0 is designed for future compliance to the SCOPE Alliances' Linux Profile 1.1.
Meeting the Needs of Telecommunications Providers
For vendors developing highly available communication systems such as central office equipment, streaming video servers or cellular base stations, or edge devices such as routers, gateways, or VoIP equipment, MontaVista Linux CGE has the right tools and technologies to get products to market quickly, cost-effectively, and with minimal risk.
Development tools are central to any software development project. MontaVista Linux CGE provides both a Platform Developer Kit and an Application Developer Kit with tools for both cross and self-hosted development platforms, as well as crash dump tools to aid the systems engineers in recovering the maximum amount of information from a crash, get the equipment back on-line as quickly as possible, and analyze any problems back in the lab. This is all backed up by MontaVista professional services and technical support engineers who are able to assist in the event of any development issues.
Other enabling technologies for communications products included in MontaVista Linux CGE include:
- PICMG feature support, including hot swap, switched Ethernet, and IPMI support
- A fully preemptive kernel and other Real-Time enhancements that result in performance 200 times more responsive than standard Linux 2.6.10 kernel
- Event logging features which allow application programs to receive and act on events from the kernel, other applications, and drivers
- Resource monitoring subsystem with APIs for tracking critical system resource usage
- High performance Linux networking subsystem, capable of delivering data at wire speeds with most CPUs
- Hardened drivers and kernel, eliminating most panics from the system
- Redundancy features, such as RSS, bonded Ethernet, and multi-host RAID
- Latency and performance measurement tools
- Journaling file systems
- Support for industry-leading network processors (NPUs)
- And many other features meeting a variety of customer application needs.
The rich MontaVista software partner ecosystem further enriches the solution offerings for communications providers. MontaVista Software actively works with various software and harware partners to ensure that databases, networking stacks, development tools, and other applications are available on MontaVista Linux CGE to provide the necessary environment for developing communications infrastructure systems quickly and efficiently.
