Protocol analyzer, non-transitory computer-readable storage medium in which protocol error detection program is recorded, and protocol error detection method

A protocol analyzer comprising:

• at least one memory that is configured to store instructions;
• and
• at least one processor that is configured to execute the instructions to:
• relay a control plane and a user plane between a radio unit and a base band unit while performing detection of an error in the control plane and the user plane that are transmitted and received to and from the radio unit configured to perform radio frequency processing and the base band unit configured to perform baseband frequency processing;
• and
• generating a failure detection packet based on error factor information generated in response to detection of the error in the control plane and the user plane and based on an ether header of the control plane or the user plane in which the error has been detected and a timestamp, wherein
• the control plane and the user plane are interpreted based on information in a management plane that determines transmission-reception conditions for the control plane and the user plane between the radio unit and the base band unit, and
• the analyzer includes a recording area for recording the error factor information, the ether header of the control plane or the user plane in which the error has been detected, and the timestamp.

A non-transitory computer-readable storage medium in which an error detection program executed by a protocol analyzer that includes at least one processor configured to execute the program is recorded, the program adapted to detect a protocol error by performing:

• protocol check processing for relaying a control plane and a user plane between a radio unit and a base band unit while detecting an error in the control plane and the user plane transmitted and received to and from the radio unit configured to perform radio frequency processing and the base band unit configured to perform baseband frequency processing;
• and
• failure detection packet generation processing for generating a failure detection packet based on error factor information generated in the protocol check processing in response to detection of the error in the control plane and the user plane, and based on an ether header of the control plane or the user plane in which the error has been detected and a timestamp, wherein
• in the protocol check processing, the control plane and the user plane are interpreted based on information in a management plane that determines transmission-reception conditions for the control plane and the user plane between the radio unit and the base band unit, and
• the analyzer includes a recording area for recording the error factor information, the ether header of the control plane or the user plane in which the error has been detected, and the timestamp.
