Multiple Associations with Stream Control Transmission Protocol
This series of articles has covered the basics of SCTP. There are many options that can control, in fine detail, the behaviour of an SCTP stack. There also is ongoing work in bringing a security model into SCTP, so that, for example, TLS can be run across SCTP. There also is work being done on different language bindings to SCTP, such as a Java language binding. SCTP will not make TCP and UDP disappear overnight, but I hope these articles have shown that it has features that can make writing many applications easier and more robust.
Of course, SCTP is not the only attempt to devise new protocols. For comparisons to other new procotols see “Survey of Transport Protocols other than Standard TCP” at www.ogf.org/Public_Comment_Docs/Documents/May-2005/draft-ggf-dtrg-survey-1.pdf. This shows that SCTP stacks up very well against possible alternatives, so you might want to consider it for your next networking project!

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
