On Network Architecture for Realizing Group-Based Communication

This paper proposes a network architecture for realizing a group-based communication to solve issues of the Internet such as lack of security and low information S/N (Signal to Noise) ratio. The paper designs a network architecture based on a multiple-association model. The proposed network architecture can realize high information S/N ratio by constructing multiple groups for different communication purposes, and can also realize security by logically separating those groups. An existing user terminal cannot be associated with multiple groups. Hence, in the network architecture, multiple groups are terminated at a gateway called SA (Security Agent), which realizes multiple association to several groups.
