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)

At Last, You Have Alternatives: Switch to Firefox and Thunderbird

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. We met with Marc...

D@TA Protection and the Linux Environment

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)

Toward Highly Available Linux Clusters

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. Introduction 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)

Linux Gains Momentum in Telecom

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 ...
