DDMG : A Data Dissemination Mechanism for Grid Environments

Vol. 6  No. 9  pp. 109-118


Until these days, the data dissemination transfer was not a fundamental feature in Grid environments. However, as the use of data-intensive applications become quantitatively and scalably increasing among Grid communities, the requirement of an effective data dissemination transfer becomes prominent. In a restricted environment like LAN or special purpose network environment the multicast transfer technology was typically used for such data transfer case. However, the limited data transfer performance of the multicast transfer, and the obligation of a special hardware setting makes it difficult to implement in a common Grid environments. Therefore, in this paper we propose DDMG(Data Dissemination Mechanism for Grid), an effective data dissemination mechanism for Grid environments. DDMG consists of an optimized P2P(Peer-to-Peer) transfer mechanism and Globus XIO library to improve the performance in data dissemination and to support heterogeneous protocols of the Grid environments. We will also evaluate the performance of DDMG by comparing with a typical unicast transfer
