Method and system for analyzing protocol message sequence communicated over a network

A network analyser comprising:

• a processor;
• and
• a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to:
• receive one or more protocol messages associated with a real-time communication session between a first network node and a second network node in the network;
• extract a set of packet attributes corresponding to the one or more protocol messages associated with the real-time communication session;
• compare each one of the set of packet attributes with a plurality of baseline attributes;
• determine at least one error condition in at least one protocol message received from the first network node based on the comparison;
• and
• perform a corrective measure on the first network node based on the at least one error condition in the at least one protocol message received from the first network node.

A non-transitory computer-readable storage medium having stored thereon instructions comprising executable code which when executed by one or more processors, causes the one or more processors to:

• receive one or more protocol messages associated with a real-time communication session between a first network node and a second network node in the network;
• extract a set of packet attributes corresponding to the one or more protocol messages associated with the real-time communication session;
• compare each one of the set of packet attributes with a plurality of baseline attributes;
• determine at least one error condition in at least one protocol message received from the first network node based on the comparison;
• and
• perform a corrective measure on the first network node based on the at least one error condition in the at least one protocol message received from the first network node.
