Isn’t BGP the “new generation?” WG docs do not favor either PIM or BGP over the other BGP for multicast: new, experimental, with certain risks: Increased J/P latency Impact on other uses of BGP Sparse Mode: we think BGP handles sparse mode okay, but there are some differences from PIM, impact remains to be seen Some customer deployments use PIM in odd ways (e.g., use more control than data) that may not fit well with BGP BGP great at disseminating state, less great at handling transactions many PIM operations are transactional this caused the BGP solution to become more complicated than originally envisaged, at least by me |
