TTE end system network management device implemented by hardware

Abstract

The invention discloses a TTE end system network management device implemented by hardware, which mainly solves the problem of poor instantaneity caused by network management in the existing time-triggered Ethernet. The TTE end system network management device comprises a capture module, a frame splitting module, a UDP header check module, a data cache module, an execution module, a framing module, and an insertion module. The capture module is connected with the frame splitting module to complete network management data reception and field extraction; the frame splitting module is connected with the UDP header check module, the data cache module and the execution module to complete the implementation of a network management instruction; the framing module is connected with the execution module, the data cache module and the frame splitting module to complete the generation of network management response information; and the insertion module is connected with the framing module to complete the transmission of the network management response information. The TTE end system network management device disclosed by the invention achieves simple and efficient network management on a time-triggered Ethernet end system, ensures instantaneity of service data processing, and can be used in the time-triggered Ethernet end system.

Description

Technical field [0001] The present invention belongs to the field of communication technology, and further relates to a network management device, which can be used in a time-triggered Ethernet TTE network. Background technique [0002] Time-triggered Ethernet TTE is based on the Ethernet communication network. Time-triggered Ethernet not only supports the transmission of traditional Ethernet services, but also supports the communication of real-time services. This has extremely high requirements on the service processing delay of the end system. The end system's processing of network management data also consumes certain system resources. Therefore, how to efficiently implement the network management of the time-triggered Ethernet TTE network end system without affecting real-time service performance is an urgent problem to be solved. [0003] Shanghai Phicomm Data Communication Technology Co., Ltd. discloses a simple network management protocol based on SNMP in its patent docume...

AI Technical Summary

Problems solved by technology

The disadvantage of this system is that, firstly, the central processing unit CPU of this system completes the processing of the protocol, which not only increases the burden on the CPU, but also affects the processing delay of the business, resulting in a change in the real-time performance of the business. Second, when configuring and managing the hardware at the remote end, it needs to be processed by software first, and the process is inefficient and complicated; third, the TCP protocol adopted requires more system resources, and the TCP retransmission mechanism will also generate large delay
