There is a lot of ongoing work to make the Linux kernel a viable operating
system option for platforms running mission-critical applications. However,
there is still some work to be done with respect to supporting new features.
This article addresses some needed features and mechanisms in the Linux
kernel - features that are necessary in server nodes operating in
mission-critical environments. Such environments include telecom, where
reliability, performance, availability, and security are extremely important.
The focus is on four features: a cluster communication protocol, support for
multiple FIBs, support for verifying digital signatures of binaries at
runtime, and an efficient low-level asynchronous event mechanism. We'll
discuss each feature, its importance, the advantages it provides, its
implementation, and the status of its integration with the Linux kernel. ... (more)
Firefox and Thunderbird are Open Source products that are made available by
the Mozilla Foundation. Open Source development lets anyone who wants to to
examine the source code, or if they wish, to modify it. There are a number of
advantages to Open Source development, including the fact that many people
look at the code every day, which results in better responsiveness as bugs
are uncovered. This dynamic development community is able to provide
continual feedback to make the product better, paving the way for a better
browsing and e-mail experience for everyone.

Organizations that gather and store critical information have to protect it.
While there are tried and true techniques for data protection, there are also
new and innovative ones. These new practices and tools greatly enhance an
organization's ability to protect mission-critical data. Linux and Open
Source users are specially challenged when trying to take advantage of much
of this new technology.
We asked technology analyst Tom Petrocelli about what is new and interesting
in data protection. Tom is president of Technology Alignment Partners
(www.techalignment.com) and author of... (more)
This article describes the HA-OSCAR architecture and features, and
demonstrates how to set up a highly available Linux cluster using the first
beta release of HA-OSCAR version 1.0.
In 2002, Ibrahim Haddad, Chokchai Leangsuksun, and Stephen L. Scott
established the HA-OSCAR (High Availability OSCAR) project with a primary
goal of leveraging the existing OSCAR (Open Source Cluster Application
Resources) technology while providing high-availability and scalability
capabilities for Linux clusters. The OCG (Open Cluster Group) recognized the
project as an official workin... (more)
OSDL's Carrier Grade Linux working group is hard at work on an open source
platform for the telecom industry. This article describes the goals,
structure, and working groups of CGL; presents the CGL architecture; and
provides an overview of the CGL 2.0 requirements.
The Linux kernel does not meet telecom requirements in various areas,
including reliability, security, and scalability. Open Source Development
Labs (OSDL) has established the Carrier Grade Linux (CGL) working group to
specify and help implement an open source platform targeted for the
communication industry that is ... (more)
