A Multicast Network Model Based on SDN and TMAggQ Algorithm

Multicast networks are widely usedcurrently, it can reduce the bandwidth consumed by transmission efficiently. However, when the network is congested, multicast trees cannot achieve load balancing of traffic, network services will not function properly. So a multicast network model based on TMAggQ algorithm is proposed to address these shortcomings. It can create MSDP tunnels, aggregate ports, and implement QoS guarantees according to the actual situation of the network, and manages them through SDN, these measures will construct a new multicast tree to avoid network congestion. A simulation experiment was conducted on the new model, the experimental results were analyzed using the Waxman mathematical model, the network simulation experiment achieves good results, the performance of the network modal is improved with a superiority of up to $20 \%$.
