Claim Text:
1. A method for providing classification of encrypted network traffic, the method comprising: (a) including, by a first classifier of a device, a first application identifier with an encrypted packet from classification of the encrypted packet by modifying, by the first classifier, the encrypted packet to include the first application identifier; (b) identifying, by a second classifier of the device, a second application identifier from classification of decrypted content of the encrypted packet; (c) determining, by the second classifier, that the second application identifier identifies a higher layer protocol than the first application identifier or identifies an application group that is a subset of an application group identified by the first application identifier; and (d) replacing, by the second classifier responsive to the determination, the first application identifier with the second application identifier as an application identifier for classification of the encrypted packet.
