| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 92 === With the rising of the development Internet, the originally designed IPv4 protocol is no longer satisfactory. Due to the constraints on not taking the shortage of IP addresses, quality of services, mobility, and the security into consideration, leads to the existence of the new IPv6 protocol. In IPv6 networks, the network nodes are easier to have multiple network interfaces or multiple IPv6 addresses forming host multihoming, resulting in many related issues. Therefore, it would be a great challenge to use IPv6 multihoming to make the same service continue when any access networks are not available or congestion.
On the other hand, with people’s anticipation on multimedia services, multicast is suitable for providing real time multimedia services, by using less network resources, it could send the packet to multicast group. In this paper, Multihomed Multicast-based Multimedia (3M) streaming system is proposed, when IPv6 hosts are in multiple access networks, by using IPv6 multihoming and IPv6 multicast, for all network interfaces are join to the same multicast group, so multimedia streaming of the same multicast group can receive from all interfaces, even when any of the access networks is congested, not available, or when horizontal handoff or vertical handoff happens, the users could still proceed multimedia streaming seamless with other available resilience network without interruption. After our 3M streaming system implementation and experiment, when any access network is not available, it can still use other available networks without any packet loss.
