Problems solved by technology

OVER technology has the disadvantage of low conversion performance efficiency
With the complexity of the network system, bridging technology requires a large number of bridging devices, and a large number of bridging devices will increase the scale of the entire network, seriously affecting the flexibility and scalability of network networking, resulting in complex networks of various systems and poor system performance. Low, when implementing protocol conversion, conversion performance is inefficient

Embodiment 1

[0056] figure 1It is a flow chart of the flow table-driven heterogeneous protocol conversion method provided by Embodiment 1 of the present invention.

[0057] refer to figure 1 , the method includes the following steps:

[0058] Step S101, obtaining the source protocol message;

[0059] In this embodiment, the source protocol message is obtained from an external stimulus source, and the external stimulus source may include but not limited to Layer 2 MAC (Media Access Control, Media Access Control). The source protocol packets obtained by the incentive source are processed and converted into target protocol packets.

[0060] When obtaining the source protocol message, it is necessary to format the source protocol message, put all the fields in the source protocol message in the packet header, and place the packet payload behind the packet header, so as to obtain the format including the packet header and packet payload source protocol packet. For example, the mic-crc in t...

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a flow table-driven heterogeneous protocol conversion method and device. Background technique [0002] At present, each communication device is based on a single communication protocol. For example, a single FC (Fiber Channel, fiber optic communication) protocol network is generally used in storage systems and aerospace systems, and RapidIO and PCIE are generally used in embedded systems and high-performance computing systems. (Peripheral Component Interconnect Express, an extension protocol for extending peripheral components) single-protocol network, data centers and traditional networks generally use Ethernet single-protocol networks. However, with the rapid advancement of combat equipment technologies such as aerospace, industrial control, ships, tanks, aircraft, radar, and electronic warfare, and the transformation of information system architecture from von Ne...
