Problems solved by technology

[0005] At present, the code rate conversion rate of the PCIe and Ethernet domains is low, resulting in low information conversion efficiency between the CPU and the IB domain, and the code rate conversion rate of the QPI domain is relatively high. However, when the CPU is configured in the QPI domain, there is currently no QPI domain and Direct connection of the IB domain or method to achieve signal conversion

Abstract

Embodiments of the present invention disclose a signal conversion method, apparatus and system, which relate to the field of communications and can perform direct conversion between a network signal in a quick path interconnect (QPI) domain and a network signal in an infiniband (IB) domain. The method comprises: extracting a destination node address (DNID) field of a QPI packet, obtaining a local address (LID) field corresponding to the DNID field, of an IB packet, using the LID field as a packet head of a converted IB packet, using the QPI packet as a data field of the converted IB packet, and performing packing to obtain the converted IB packet; or extracting a data field of an IB packet, and packing the data field of the IB packet into a converted QPI packet. The embodiments of the present invention are used for conversion between a network signal in a quick path interconnect domain and a network signal in an infiniband domain.

Description

technical field [0001] The present invention relates to the communication field, in particular to a signal conversion method, device and system. Background technique [0002] IB (InfiniBand, infinite interconnection) is a unified interconnection structure, which is applied to the communication between servers, servers and storage devices, and servers and networks. IB switches route packets through subnets, and IB routers connect multiple subnets together. Compared with Ethernet, IB can be managed in a more decentralized manner. There is a manager in each subnet, which plays a decisive role in routing packets, mapping network topology, providing multiple links in the network, and monitoring performance. Therefore, the connection between the IB domain network and the CPU is very common. [0003] The current way of connecting the CPU to the IB domain network is mainly to place the CPU in the PCIe (Peripheral Component Interconnect express, high-speed peripheral component inte...
