Abstract: Techniques for determining the relationships between a network of services include determining encoding of text fields received and transmitted by the services. Correspondence between the bytes representing a text string in a first data field and encoding data that associates byte characteristics with encoding schemes may be used to determine the encoding scheme associated with the first data field. Other data fields that were transmitted or received close-in-time to the first data field and have a value within a threshold similarity of that of the first data field may be determined to be associated with the first data field. Subsequent to a modification to the network of services, if the encoding of one or more data fields changes or if the associations between data fields change, the particular services that were affected by the modification may be determined based on the differences in encoding schemes and data field associations.
