Research and implementation of disk over ethernet protocol

To overcome the limitation of TCP/IP protocol that multi-copys and context switch are needed in the network storage system which result in the poor performance of the system, a lightweight transport protocol named DOEP (Disk Over Ethernet Protocol) is presented. DOEP drawing on the idea of zero-copy increases the throughput of the network storage system and reduces the system workload by reducing protocol layers and data copy times, and employing efficient flow control mechanism. The test result shows that DOEP has better performance than TCP/IP under Ethernet storage environment.
