The basic requirements that communications and data service network providers
try to meet are availability, reliability, performance, and response-time
requirements. So far these were being achieved by building on proprietary
platforms that are closed systems, expensive to develop and maintain, and lack
support for third party software and emerging standards.
Today, the industry is turning away from proprietary platforms towards open,
standards-based building blocks for hardware, software platforms and high
availability middleware. This approach offers cost-effective, timely delivery of
new architectures, new services, and increased bandwidth.
CGL stands at the center of the move to open architectures in the telecom
industry. The initiative began with the vision that communication services will
be delivered using open standard carrier grade platforms to overcome the
restrictions of traditional proprietary solutions. “CGL is reaching the stage
where Linux was four years ago at the enterprises. It's still in the growth
phase but already carriers and network equipment vendors (NEPs) are attracted to
the overall benefits of Linux-vendor independence, openness, extensibility,
and cost-and they recognize its potential for their markets,” says Satish
Mohan, head, Engineering, Red Hat India.
As the market for Linux-based telecommunication products continues to grow,
products based on CGL are being developed by some of the world's largest
equipment manufacturers and Linux software developers. Mukul Agrawal, managing
director, Unisys Global Services India, shares some encouraging signs, “The
tide is turning for the telecommunications market. Recent announcements from a
number of ISPs demonstrate the increasing adoption of Linux to reduce costs and
enable a higher level of flexibility in telecommunications devices. CGL is
increasingly being adopted by telecom service providers, airlines and banks.”
Must Standardize
Convergence of telecommunications, computers and broadcasting, has led to
the emergence of more integrated info-communication choices for consumers.
Standardization is a crucial part of this new picture, as it delivers global
interconnectivity and interoperability among different equipment, systems and
networks, promising truly ubiquitous use of info-communications for users.
Organizations like Asia-Pacific Telecommunity (ATP) strongly moot the
proposal of having a framework for open telecom systems especially for the
Asia-Pacific region where standardization is essential to harmonize the need of
the market, the available technologies and the manufacturing capability.

“A common framework for the TEMs and NEPs ensures faster time to market and
CGL propels standardisation in the telecom market,” says Praveen Sawkar,
regional manager – South Asia, Sun Microsystems. “For the service provider,
it is beneficial to have a common or standardised platform to deploy advanced
technologies. Also this eliminates vendor lock-in,” he adds.
With the emergence of IP-based telephony, carriers have started to look at
technologies based on open standards. Increasingly, open software and commercial
off-the-shelf (COTS) hardware are
being seen as the means for rapid deployment of new voice and data services,
while reducing capital expenses and operating costs, enabling equipment
providers to stay competitive and profitable.
The OSDL Backing
To crystallize CGL with the objective of achieving the functionality and
performance needed for carrier-grade platforms, the Open Source Development Lab
(OSDL) established the Carrier Grade Linux Working Group (CGLWG). This body,
comprises leading telecom vendors and open source software developers, gathers
requirements, publishes specifications, and guides the direction for efforts
needed to achieve carrier grade Linux.
CGL gained more momentum with leading telecom vendors supporting it, who
became the core members of the OSDL CGLWG. Linux distribution suppliers are now
demonstrating that they can meet the emerging needs of telecommunications by
registering (disclosing publicly) how their Linux-based software platform
products address the requirements as defined in the CGL Requirements Definition.

The CGLWG identified three main types of applications that carrier-grade
Linux will support-gateways application, signaling server and management
server applications. As for mobile networks, CGL will target all types of server
nodes running at all layers of a next generation network: service, control and
connectivity layers. “CGL is simply a branding mechanism provided by OSDL.
Linux distributions can register with CGL, and this action announces an
alignment of the distribution features with the requirements in the CGL
specification. There is not a formal certification suite,” clarifies Faisal
Paul, country manger, High Performance Computing, HP India.
Increasing Footprint
In February this year, the CGL version 3.2 specifications were released,
following which several Linux distribution companies have registered. The SCOPE
Alliance, a grouping of major telecom networking equipment vendors, published a
profile for a carrier-grade Linux operating system. The profile published in
June this year, builds on the CGL 3.2 and prioritizes the CGL 3.2 'roadmap'
that is necessary to support carrier-grade base platforms for network equipment
providers.
