Document Type and Number:
Japanese Patent JP4799118
Kind Code:
B2
Abstract:
Two logical partitions within a single computer communicate with each other internally. The protocol stack of a first logical partition generates a frame in a memory space provided in a driver and referred to by the first logical partition. The driver transfers the frame generated in the memory space of the first logical partition to a communication port of a Layer 2 switch using DMA. The communication port of the Layer 2 switch loops back the frame input from the driver. An interrupt is signaled to the driver and the frame is transferred from communication port of the Layer 2 switch to the driver using DMA. The frame is received in a memory space referred to by a second logical partition.
