Remote asymmetric end communication method based on Ethernet

Abstract

The invention discloses a remote asymmetric end communication method based on the Ethernet. By the remote asymmetric end communication method based on the Ethernet, remote communication between an external controller and field programmable gate array (FPGA)-based central processing unit (CPU)-free weak intelligent network equipment is realized. In the method, an Ethernet-based communication framework between the external controller and the FPGA-based CPU-free weak intelligent network equipment is provided, a communication protocol of interaction between the external controller and the FPGA-based CPU-free weak intelligent network equipment is defined, and interaction command type and format, message package and the like are defined, therefore the remote communication between the external controller and the FPGA-based CPU-free weak intelligent network equipment is realized. By using the method, a user can configure the FPGA-based CPU-free weak intelligent network equipment in a network and can realize remote management configuration for the FPGA-based CPU-free weak intelligent network equipment by using the external controller; therefore, the method has great significance for development and application of an FPGA-based network.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an Ethernet-based remote asymmetric terminal communication method. Background technique [0002] The network equipment developed and designed based on the method of FPGA has been widely concerned by network researchers. The reconfigurable feature of FPGA logic provides a more flexible development and design method for the rapid development of network equipment prototypes, test and verification of network functions, etc. However, compared to the complex calculation and control of the CPU, the FPGA can only implement sequential or state machine-based logic functions, and has weak intelligence; on the other hand, the FPGA is limited by on-chip resources and processing capabilities, and the Complex state control overhead is huge, and the functions of network devices are often complex and uncertain, which brings difficulties to FPGA-based development and design. At present...
