그룹 통신에서는 일대일 통신과는 달리 통신에 참여하고 있는 참여자들에 대한 관리가 필요하다. 이러한 참여자 관리는 참여자들의 정보, 현재 상태 등을 체크하는 기능이 필요하며 이러한 참여자들의 정보 및 상태를 멤버쉽이라고 부른다. 본 논문에서는 이러한 참여자들의 멤버쉽을 관리하고 유지하는 멤버쉽 관리 프로토콜(MMP Membership Management Protocol)을 설계하였다. MMP는 서버/클라이언트 기반으로 동작하며, 서버가 모든 클라이언트들의 멤버쉽을 관리한다. 클라이언트는 주기적으로 서버에게 자신의 상태를 보고하고, 멤버쉽 갱신을 원할 경우 서버에게 요청한다. 설계된 MMP는 알고리즘이 간단하기 때문에 그룹 통신에서 간단하고 효율적인 멤버쉽 관리를 할 수 있으며, 서버가 모든 멤버쉽을 관리하기 때문에 송신자의 부담이 줄어든다.
