The Stream Control Transmission Protocol (SCTP) is a reliable transport protocol that provides stable, ordered delivery of data between two endpoints (much like TCP) and also preserves data message boundaries (like UDP). However, unlike TCP and UDP, SCTP offers such advantages as multi-homing and multi-streaming capabilities, both of which increase availability. In this article, get to know the key features of SCTP in the Linux® 2.6 kernel and take a look at the server and client source code that shows the protocol's ability to deliver multi-streaming.

The goal of this IBM Redbook is to provide a technical reference for IT systems administrators in organizations that are considering a migration from Solaris to Linux-based systems. We present a systems administrator view of the technical differences and methods necessary to complete a successful migration to Linux-based systems, including coverage of how those differences translate to two major Linux distributions: Red Hat Enterprise Linux and SUSE Linux Enterprise Server.

The Sockets API lets you develop client and server applications that can communicate across a local network or across the world via the Internet. Like any API, you can use the Sockets API in ways that promote high performance -- or inhibit it. This article explores four ways to use the Sockets API to squeeze the greatest performance out your application and to tune the GNU/Linux® environment to achieve the best results.

Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.

What's the first thing that you do once you've logged onto Linux? Is it to manually start up a processes such as Apache or MySQL, or even start your network connection? Or do you have to stop applications that have started up without your telling them to, and which are overloading your machine? If you have unwanted processes starting at boot time, or find yourself starting necessary services manually, let's make your life a little bit easier by introducing you the world of Linux services.
