Linux WAN Routers

Here's another great use for Linux; Mr. Mancill tells us why his company picked Linux routers over the big names.

The intent of this article is not to say that Linux routers will make traditional routing hardware obsolete. When considering routing hardware, make sure that the tool fits the job at hand. If you have a T-3 to the Internet or want to tie together remote sites with ATM, you probably need to be shopping for equipment designed explicitly to switch and route packets at those speeds. By the same token, why go to the extra expense and trouble to deploy a special-purpose piece of hardware, along with all of the inconveniences that come with it, when you only need to route 128Kbps or even 1.5Mbps?

Because no one can foresee all of the demands that will be placed on their routing environment, flexibility and expandability are desirable in any solution. The Linux kernel is rapidly supporting increasingly more sophisticated types of traffic-shaping and packet monitoring. Routing hardware, including the processor, can be upgraded inexpensively. Furthermore, this same hardware can provide additional functions. Finally, a Linux router comes equipped with a complete set of familiar tools for monitoring and customization.

For a minimal investment in hardware and time, you can try a Linux router for a new link or to act as a backup for your current link(s). If you are new to data communications or need support, you are more likely to find a Linux hacker who can read (which is all it takes to get a Sangoma card running) than to find a BigName router guru. Typically, Linux folks are pretty friendly and willing to help. After all, some of this stuff is just neat. For business environments, the availability of Linux talent is increasing, and training for this environment is substantially less expensive than for closed-systems. Because Linux is open, your investment of time and capital is better protected. Give it a try. You will not regret it!


Tony Mancill spent a lot of time studying Electrical Engineering before graduating from Georgia Tech, only to end up playing with computers all day. When he's not working at LHS Communications Systems, he divides his time between playing the drums, home-brewing his own beer and trying to teach his dog new tricks. He has recently volunteered for the GNU/Debian Linux project as the maintainer of the wanpipe package. You may contact him via e-mail at

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
