Description
Summary:As growth of network technology and device technology, smart devices equipped multiple network interfaces now are increasingly emerging, and also these are able to communicate with other devices and services using the multiple networks simultaneously. Currently, transmission method using concurrent multiple paths has been studied in IETF, however there are several problems for performance degradation when traffic flows are transmitted through multiple paths over wireless networks. For instance, mobile user moving fast to different wireless network is occurring to frequently re-establish new sub-paths, so that overall throughput could be degraded even though communication session is maintained. Therefore, the paper identifies above problems and introduces new multipath transmission support architecture for heterogeneous wireless networks. The architecture introduces a novel entity `Multipath Anchor (MA)', which supports not only multipath transmission but also deployabiliy by proxing and relaying packets to the receiver. Basic transmission process and handover process are describes. And we also discuss about deployment issues to realize the architecture, so MA can be installed by 3 rd party. In the future works, the architecture will be implemented based on NetFPGA, and scheduling and traffic division policy will be proposed.
