Implementing Path-Exploration Damping in the Quagga Software Routing Suite Version 0.99.13 - Patch Set Version 0.3

Quagga is a software routing suite which provides implementations of various routing protocols for UNIX based platforms. It supports implementations of RIP, OSPF and BGP version 4. Path-exploration damping (or simply path-damping) is one possible approach to filter out the path hunting phenomenon in BGP, in which a single prefix withdrawal event at the original announcement's origin may generate a large volume of subsequent updates as the routing system converges. Implementing path damping in Quagga, using version 0.99.13, results in a fully operating routing suite which makes use of this technique. This paper describes the patch set version 0.3 of the path exploration damping implementation in Quagga version 0.99.13, obsoleting CAIA Technical Reports 081117A and 090327A.
