Abstract:
1. A computer implemented method for verifying service policies of routing network traffic in a network element, the method comprising: receiving a number of classes of network traffic, each class having a number of classification rules; outputting a result indicating a first class of the number of classes conflicts with a second class of the number of classes upon determining that at least one of classification rules of the first class overlaps with one of the classification rules of the second class, wherein the outputting of the result indicating the first class conflicts with the second class upon determining that the at least one of the classification rules of the first class is nested overlapped with one of the classification rules of the second class; in response to the result, modifying at least a portion of the classification rules of the first and second classes to reduce the conflicts between the first and second classes; and routing network traffic associated with the first and second classes according to the modified classification rules of the first and second classes.
