A new article on using the GNU Virtual Private Ethernet (GVPE) service is available on IBM developerWorks:
Providing a secure communication conduit implies many different issues and problems, such as how you provide an effective communication channel that is capable of handling multiple streams of information. Using the GNU Virtual Private Ethernet (GVPE) provides an alternative to the normal single or multiple channel solutions by effectively emulating the entire network stack and allowing you to build TCP, UDP and other network technologies on top of the virtual environment. This article examines ways of using GVPE with your applications to provide communication, and of using GVPE with your Web sites to provide secure connectivity over private and public networks. In particular you’ll learn about using GVPE with distributed infrastructure projects, such as Amazon EC2, clouds, or public/private web performance deployments.
