摘要
The problem of control and routing of broadband multimedia traffic has been considered in this paper. We suggest SDN-based network infrastructure for IPTV. Within the infrastructure IGMP and PIM are replaced by our OpenFlow-based protocol. To control multicast quality, we also propose real-time selective marking of IP packets by means of unique tags on input device, so monitoring respective stream quality and correcting it if necessary. A simulation model of broadband multimedia multicasting infrastructure based on SDN has been developed. The infrastructure performance has been studied on OMNET++ simulator. The experiment shows a growth of switch performance up to twice as much when the OpenFlow is used for processing multicast streams.
