The social relation determines the distribution of multicast destinations. The social features (social group size and relation)determine the network features(multicast scale and destination distribution)and further impact the network performance such as capacity. We investigate the impact of social features on network capacity in this paper. 9Previous Works & Motivation Our view on the multicast social networks ➢ According to the mentioned theory of social networks and multicast, we can conclude the relation between social features and multicast as follow: ✓ The social group size determines the multicast scale. ✓ The social relation determines the distribution of multicast destinations. 9 We investigate the impact of social features on network capacity in this paper. ➢ The social features (social group size and relation) determine the network features (multicast scale and destination distribution) and further impact the network performance such as capacity
