Protocol monitor
First Claim
1. A method of monitoring the behavior of a protocol contained within a network frame having at least one protocol data unit, containing at least one field, comprising:
- receiving a set of network frames from a network;
filtering a one of the set of network frames for monitoring, the one of the set of network frames having at least one protocol data unit;
retrieving protocol knowledge of the data structure of the at least one protocol data unit enabling the extraction of the at least one field;
extracting a value from the at least one field of the at least one protocol data unit; and
updating protocol status on a user interface with the value.

Abstract
Protocol Monitor. A protocol monitor provides the ability to allow a user interface to be updated with protocol status and event information. For monitoring the behavior of a protocol contained with a network frame, network frames are received by the network device and then network frames are filtered according to which protocol is being monitored. Next, the protocol knowledge of the data structure of the network frame is retrieved by a protocol decoder. This enables the extraction of a field contained within a protocol data unit of the network frame which is needed to monitor the protocol behavior. A value is extracted from the field and represented by a keyword. This value is used to update the protocol status or protocol events on the user interface.
