[0002] As the cornerstone of the modern information society, computing networks carry the task of transmitting and processing massive amounts of data. However, in actual operation, data packets may be damaged due to a variety of reasons, such as transmission errors, equipment failures, and network congestion. These damages not only affect the performance and stability of the network, but may also cause data loss or service interruptions, posing a serious threat to user experience and business continuity.
[0003] Due to the limitations of laboratory environment, it is difficult to fully simulate the complex networking and damage conditions in real scenarios. Therefore, the industry urgently needs a technical solution that can simulate and detect packet damage and effectively evaluate the network's response capabilities.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] A best embodiment is given below:
[0030] like Figure 1 As shown, a method for constructing computing network traffic damage based on VPP in this embodiment has the following steps:
[0031] S1. Develop a data packet damage function plug-in in the VPP framework;
[0032] First, a packet damage function plug-in is developed in the VPP framework. The plug-in configures the packet matching rules and damage parameters through the vppctl command.
[0033] The packet damage plug-in configures the packet matching rules and damage parameters through the vppctl command;
[0034] The data packet damage function plug-in is equipped with a damage processing module and an interface. The damage processing module performs packet loss processing on the matching messages according to the preset damage configuration. The interface allows the user to dynamically adjust the damage configuration parameters to meet different test requirements.
[0035] By utilizing the efficient packet processing capability of the VPP framework, a packet impairment plug-in is designed and implemented. This plug-in can simulate various types of packet impairments, such as packet loss, delay, disorder, duplication, and damage.
[0036] By configuring the vppctl command, packets are matched according to the packet's five-tuple (source IP address, destination IP address, source port number, destination port number, protocol type) or APNID (application protocol identifier), so that the corresponding packets are lost and damaged according to the configured percentage.
[0037] S2. In the computing network, select specific nodes as the head node and tail node of the computing gateway; these nodes need to support flow detection functions, such as IFIT detection.
[0038] The head node is responsible for receiving messages from the outside and forwarding them to the damage function node for damage simulation. The tail node is responsible for receiving messages that have been damaged and performing flow detection and analysis.
[0039] A dedicated test channel can be established between the head node and the tail node to ensure the accuracy and reliability of the test results.
[0040] The packet damage function plug-in can be placed on specific nodes of the computing network, such as after the computing gateway head node and before the computing network tail node. These nodes support the flow detection function and can detect the current network status in real time.
[0041] When the message passes through the computing power gateway node, it will enter the damage function node for packet loss damage simulation. The damage function node will perform damage processing on the message according to the preset damage configuration (such as 5%, 10%, 20%, 30% and other percentage packet loss).
[0042] The damaged packets will continue to be transmitted to the tail node of the computing power gateway. The tail node will use the flow detection function (such as IFIT detection) to monitor and analyze the transmission of the packets to evaluate the network's ability to cope with damage.
[0043] S3. Build a network response capability evaluation model, including the calculation methods and evaluation criteria for key performance indicators such as throughput, latency, and jitter;
[0044] A visualization interface is developed based on the network response capability assessment model to display damage simulation and assessment results. The interface includes functional modules such as damage type selection, damage degree setting, and network performance indicator display. Users can easily view and analyze the assessment results through the visualization interface and perform corresponding network optimization and adjustment operations based on the results.

By adjusting the damage configuration parameters and observing the changes in network performance indicators, the accuracy and effectiveness of the present invention in simulating data packet damage and evaluating the response capability are evaluated.
[0047] According to the test results, necessary optimization and improvement are carried out on the present invention to improve its performance and reliability.

The damage processing module performs packet loss processing on the matching messages according to the preset damage configuration. The interface allows the user to dynamically adjust the damage configuration parameters to adapt to different test requirements.
[0050] In the computing power network, specific nodes are selected as the head node and tail node of the computing power gateway, and a network response capability evaluation model is built, including the calculation method and evaluation criteria of key performance indicators, and finally tested and verified.
[0051] Among them, the head node is responsible for receiving messages from the outside and forwarding them to the damage function node for damage simulation. The tail node is responsible for receiving messages that have been damaged and performing flow detection and analysis. A dedicated test channel is established between the head node and the tail node.
[0052] Based on the network stress capacity assessment model, a visualization interface is developed to display the damage simulation and assessment results. Users can view and analyze the assessment results through the visualization interface and perform corresponding network optimization and adjustment operations based on the results.
