Research And Implementation Of Multicast Group Membership Management Protocol Based On The New Network Architecture

Multicast technologies help multicast communication service,such as remote video conference and online games,etc.,to reduce the bandwidth resource,network congestion,and delay.Internet Standard Organization has published numerous IP Multicast Standard in recent years.But the IP multicast has not been deployed in large-scale.This is because the current multicast technologies adopt the open multicast service model,which does not support identity authentication.The legality of the multicast member is difficult to be guaranteed.Moreover,the mobility management for mobile terminals is also lacked.Therefore,this paper adopts the novel network architecture design to research the multicast member management technologies and proposes a multicast member management protocol.The contributions of this paper include:(1)Design the multicast user management protocol workflow;(2)Define the multicast user management protocol packet format;(3)Implement the multicast user management protocol function module;(4)Test and evaluate the multicast user management protocol.To test the feasibility and performance of this mechanism,this paper establishes the network topology and installed related software.The function and consistency are also tested.The results demonstrate that the proposed multicast management protocol is able to achieve the access control,management and maintenance,etc.We believe the proposed protocol is capable of providing basic service assurance and reference value.
