dc.description.abstract近幾年來將群播服務放在疊蓋式網路中相關研究越來越受到重視,也有許多研究顯示在疊蓋式網路是適合實現群播機制的環境。在現今的環境中,點對點的分享十分的流行,熱門檔案被分散在許多節點中,而被特定的試用者所需求。所以在資料傳輸中,我們可以發現中間幫忙傳遞的節點成了提昇整體系統效能中的瓶頸。網路編碼是用來提高網路檔案傳輸的一種編碼方法。節點要有可以支援編碼和解碼檔案的功能。在本篇論文中,我們在疊蓋式網路中,提出一個基於網路編碼的群播機制。並且我們將提出的機制建立了一個數學模型,基於此數學模型,我們可以來比較系統的效能的提升。由數學模型所顯示的結果證明藉由網路編碼,我們確實有提高原有群播服務的效能。除此之外,我們也加上了雙向認證和團體金鑰的分配。我們不需要額外的封包傳輸來達到上述的功能,相對的我們把上述的資料揹負在網路編碼的封包之中。zh_TW
dc.description.abstractMany researches have shown that overlay network is an applicable environment for providing multicast service. In current internet environment, popular data is shared and queried by many peers. The bottleneck may be the intermediate nodes that help forward packet from data providers to receivers and vice versa. Network coding is an information-theoretical coding method proposed to improve data transmission efficiency of a given network topology. It claims that nodes in the topology support to encode/decode data and with network coding, the efficiency of whole system can be improved. In this paper, we propose a network coding based multicast scheme in overlay networks. We model our scheme and shows that our work has better performance of system throughput and we also provide a mutual authentication and group key distribution scheme without other message transmission.en_US
