Measuring start-up times in the multicast protocols PIM dense-mode and PIM sparse-mode (English)
Abstract [sv]

I denna rapport undersöks vilket multicastprotokoll som behöver minst tid till att starta en multicastström från sändare till mottagare. Protokollen som mäts är IPv4 PIM dense-mode, IPv4 PIM sparse-mode samt IPv6 PIM sparse-mode. Mätningarna baseras på hur lång tid det tar från att en klient skickar förfrågan om att få gå med i en multicastgrupp till att klienten mottar multicastströmmen. Mätningsresultaten genom Cisco 2901 routers visade i vår labbmiljö att PIM dense-mode behöver minst tid för att leverera trafiken i jämförelse med IPv4/IPv6 PIM sparse-mode. Alla protokoll visade sig prestera under 20 millisekunder sett till medianen, vilket är under gränsen för vad en människa anser ske omedelbart

Abstract [en]

This report studies which multicast protocol that requires the least amount of time to forward a multicast stream from sender to receiver. The protocols measured are IPv4 PIM dense-mode, IPv4 PIM sparse-mode and IPv6 sparse-mode. The measurements are based on the time between the client announcing participation in a multicast group to actually receiving the first multicast stream packet from the router. In a lab environment with Cisco 2901 routers we came to the conclusion that IPv4 PIM dense-mode required the least amount of time compared to IPv4/IPV6 PIM sparse-mode. Every protocol managed to stay below 20 milliseconds median, which is within the limit of what a human sees as instantaneous
