JOON-SUAN ONG is an academic who published a paper in 2003 entitled Network virtual memory. JOON-SUAN ONG published this work as part of a team: Ong, Joon Suan. Here is a description of this work: User-mode access, zero-copy transfer, and sender-managed communication have emerged as essential for improving communication performance in workstation and PC clusters. The goal of these techniques is to provide application-level DAAA to remote memory. Achieving this goal is difficult, however, because the network interface accesses physical rather than virtual memory. As a result, previous systems have confined source and destination data to pages in pinned physical memory. Unfortunately, this approach increases application complexity and reduces memory-management effectiveness. This thesis describes the design and implementation of NetVM, which is a network interface that supports user-mode access, zero-copy transfer and sender-managed communication without pinning source or destination memory. To do this, the network interface maintains a shadow page table, which the host operating system updates.
