| dc.description.abstract | With the rising of the development Internet in the past years, the originally designed IPv4 protocol is no longer satisfied. 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. Therefore, how to apply the technology of IPv6 multihoming to achieve the connectivity of original service when the users are roaming in the IPv6 heterogeneous networks is the topic of this paper.
On the other hand, whether joining in a multicast group is depending on client so that multicast is suitable for providing real time multimedia services in wireless mobile heterogeneous network. But if multicasting to all network interfaces will cause the problem of bandwidth utilization. In this paper, Seamless Multimedia Streaming by Dynamic Multicast in All-IPv6 Multihomed Networks is proposed. When IPv6 hosts are in multiple access networks, even when any of the access networks is congested, unavailable, or under horizontal handoff and vertical handoff , the users can still proceed multimedia streaming seamless with other available network without interruption by using IPv6 multihoming, IPv6 multicast, and detecting the status of current network interfaces to join in the multicast group dynamically. After implementation and experiment of streaming system, it can still use other available network interfaces to join or leave multicast group dynamically to keep original service seamlessly when any access network is not available. It spends less cost on bandwidth than joining all interfaces in the same multicast group. | en_US |
