Embodiment Construction

[0014] Cooperate with chart below and describe preferred embodiment of the present invention as follows:

[0015] Please refer to figure 1 , is a schematic diagram of the hardware architecture according to the present invention. The data transmission method between hosts of the present invention is suitable for transmitting the data of the first host 20 to the second host 30 . The first host 20 and the second host 30 are interconnected by a peripheral component interconnect extension 40 (Peripheral Component Interconnect, PCIExpress).

[0016] The first host 20 and the second host 30 may be but not limited to servers, and the first host 20 and the second host 30 may be local and remote service hosts respectively. The description of the following embodiments is described by sending data from the first host 20 to the second host 30 as an example, but the present invention is not limited thereto, and the present invention can also be applied to sending data from the second host...

Abstract

The invention discloses a method for transmitting data between hosts, which is suitable for the data transmission between two hosts with interconnected and expanded peripheral device components. The transmitting method comprises the steps of establishing a source buffer zone in an internal memory of the first host, cutting into source blocks, establishing an objective image area in an internal memory of the second host, cutting into objective blocks, converting the to-be-transmitted data into data segments, writing the data segments and metadata in the source blocks by utilizing the first host, sending interrupt notice to the second host by utilizing the first host so as to inform the second host to receive the data and sequentially writing the received metadata and the data segments in the objective blocks by utilizing the second host. By means of the method, the data transmission efficiency between the hosts can be increased.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a data transmission method between two hosts. Background technique [0002] Data transmission between computers is quite frequent, so the transmission rate will directly affect the performance of the computer. After the popularization of network technology, data transmission between computers is more frequent, so the requirements for data transmission rate are also relatively increased. In recent years, under the massive application of service systems, the demand for high-speed data transmission is also increasing. [0003] In order to increase the data transfer rate, support high reliability (HA, High Availability), and make the system as simple and effective as possible, the industry has proposed an advanced switching architecture based on peripheral component interconnect (PCI Express) (Advanced Switching Architecture), a non-transparent bridge (non-transparent Bridge, NTB) tech...
