Introduction to the quagga routing suite

Off-the-shelf routing products are often constrained by being designed to meet specific needs, in terms of both software and hardware. Networking professionals may face problems that require customization of software, or additional processing facilities or data storage, which are not provided for by those products. The Quagga Routing Suite provides implementations of several common routing protocols, distributed over multiple processes communicating via IPC, and support for their development, with source code provided under a modification-friendly license. Quagga can help networking professionals build such custom solutions, in combination with other open source software packages. Quagga also provides a path for network researchers to increase the visibility of their work, making it available to a wider community for potential testing and use, increasing the impact of that research.
