Multiple Associations with Stream Control Transmission Protocol

The elegant way SCTP handles multiple streams makes it ideal for things like chat clients.
Conclusion

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!

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
