Problems solved by technology

[0004] At present, data replication depends entirely on the operating system of the central node or data node. When the business pressure is very high, it is easy to cause the node to crash; and due to the software processing capability of the central node or data node, it depends on the CPU processing capability and the main frequency and size of the memory. , causing the key hardware threshold to be too high and hardware costs soaring
In addition, the software processing speed is not as fast as the hardware, relying on software processing, the overall cost performance is not high

Embodiment Construction

[0038] The invention provides a message duplication method and a novel network adapter. In the method, the novel network adapter obtains the pre-duplicated data cached in advance by identifying the message descriptor in the message payload. Then, the packet descriptor in the payload is replaced with the pre-duplicated data, completing a copy of the data and successfully exempting the application layer from the pressure of data duplication.

[0039] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 Shown are the key components of the novel network adapter of the present invention and the pre-storage process of the data to be copied. Among them, the new network adapter has a hardware processor, the storage unit can share the host memory, the Hash hash unit and the Checksum calculation unit can be replaced by the software algorithm of the processor, but for performance consi...

Abstract

The invention discloses a message replication method and a novel network adapter supporting a message replication function. The message replication method comprises the steps of identifying a messagedescriptor in a message load by the novel network adapter to obtain to-be-replicated data which are buffered in advance; and then replacing the message descriptor in the load with the to-be-replicateddata to finish one replication of the data. The data replication pressure of an application layer is avoided successfully. The novel network adapter comprises a processor, a storage unit, a to-be-replicated information management unit or algorithm and a checksum calculation unit or algorithm. The message replication method and the novel network adapter supporting the message replication functionare applied to the fields such as cloud storage and data safety; the data replication and calculation pressure of the center node of the cloud storage can be shared; the hardware resource utilizationrate and the processing speed of the node available for the data processing are improved greatly; the hardware cost is saved to a great extent; and a high promotional value is obtained.

Description

technical field [0001] The invention relates to computer networking equipment, in particular to a message duplication method and a novel network adapter supporting the message duplication function. Background technique [0002] A network adapter is a network component working at the link layer. It is an interface connecting a computer and a transmission medium in a local area network. Encapsulation and unpacking, media access control, data encoding and decoding, and data caching functions, etc. [0003] In the era of cloud computing, big data and cloud storage were born. While realizing distributed data storage, data security has also been paid more and more attention. The industry generally adopts a data backup solution to solve the problem of data incompleteness caused by a single node failure. In the cloud storage scenario, when the central node sends data to the primary data node, it also needs to copy and distribute the same data to the backup node at the same time. ...
