Method for Obtaining Standard Configuration Template of Network Device, and Computing Device

A computing device, wherein the computing device comprises:

• a non-transitory memory storing instructions;
• and
• a processor coupled to the non-transitory memory and configured to execute the instructions to cause the computing device to be configured to:
• obtain configuration commands of a plurality of network devices;
• and
• generate a command template set based on the configuration commands of the network devices, wherein the command template set comprises a plurality of command templates;
• generate a correlation matrix based on the command template set, wherein the correlation matrix comprises a plurality of correlation values, and wherein each of the correlation values indicates a correlation between a command template and one of the network devices;
• cluster the network devices based on the correlation matrix to obtain at least two categories of the network devices;
• divide the correlation matrix into a plurality of submatrices based on a clustering result, wherein each submatrix corresponds to one of at least two of the categories of the network devices, and wherein a correlation value in each submatrix indicates a correlation between a command template in the command template set and a network device of a corresponding category of the network devices;
• and
• perform singular value decomposition on each of the submatrices to obtain a non-zero singular value;
• and
• use, as a standard configuration template of the corresponding category, a command template in the command template set that makes a contribution greater than a threshold to the non-zero singular value.
