LAYER 7 APPLICATION CLASSIFICATION

摘要

Maintaining layer 7 state as a client device roams between network devices during a session. Data packets used in executing a layer 7 application are received at a first network device that a client device is coupled to during a session. Data packets received by the first network device are stored in a layer 7 application buffer that is sent to a second network device that a client device roams to during a session. A layer 7 application buffer is used to classify a layer 7 application that is the subject of a session in order to maintain layer 7 state as a client device roams to a second network device during a session.

1. A method comprising:
receiving, at a first network device, one or more packets associated with a layer 7 application session of a client device; storing at least a portion of each of the one or more packets received at the first network device in a layer 7 application buffer; sending at least a subportion of the portion of at least one of the one or more packets stored in the layer 7 application buffer to a second network device; determining application information for the layer 7 application from the at least a subportion of the portion of at least one of the one or more packets; classifying the layer 7 application using the application information to maintain layer 7 state when the client device roams from the first network device to the second network device.
