Passive Measurement Result of AS Path Prepending from the RouteViews archives (updated in Jun 2006)
We use our previous measurement results [1] derived from the RouteViews data to discuss the prevalence of AS Path Prepending in inbound traffic engineering in the existing network.

Figure 1. The trend on the percentage of stub ASes, multihomed stub ASes, and transit ASes. |

Figure 2. The percentages of multihomed stub ASes and transit ASes
that perform prepending on their routes and perform prepending based
on link-based prepending policy. |

Figure 3. The percentages of links that are involved in the
link-based prepending policy. |

Figure 4. The percentages of routes with prependings observed from
the RouteViews data. |

Figure 5. The percentages of source prepending, intermediary
prepending, and mixed prepending in the prepended routes. |
