A method of analyzing a protocol message sequence communicated over a network, the method comprising: receiving, by a network analyzer, 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; extracting, by the network analyzer, data-field-values that pertain to: Maximum-, Max-, forwards, Command Sequence, CSeq number, content-type, and content-length for each protocol message received from the first network node, comparing, by the network analyzer, each one of the extracted data-field-values with a plurality of baseline values associated with each of the plurality of network protocols, wherein the comparison is based on the plurality of baseline values, which are dynamically updated by the network analyzer based on learning from a mapped information of corrective measures and associated errors relevant to the one or more protocol messages; determining, by the network analyzer, at least one error condition pertaining to: invalid Max-forwards, invalid CSeq number, invalid content length, and invalid content-type in at least one protocol message received from the first network node based on the comparison; and performing, by the network analyzer, 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, wherein performing the corrective measure by the network analyzer comprises: adjusting a configuration setting that comprises: nodal tables, addresses and/or policies in the first network node corresponding to the at least one error condition in the at least one protocol message; and generating the at least one protocol message with valid data fields or valid extensions for a subsequent communication session based on the adjusted configuration setting in the first network node. receiving, by a network analyzer, 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; extracting, by the network analyzer, data-field-values that pertain to: Maximum-, Max-, forwards, Command Sequence, CSeq number, content-type, and content-length for each protocol message received from the first network node, comparing, by the network analyzer, each one of the extracted data-field-values with a plurality of baseline values associated with each of the plurality of network protocols, wherein the comparison is based on the plurality of baseline values, which are dynamically updated by the network analyzer based on learning from a mapped information of corrective measures and associated errors relevant to the one or more protocol messages; determining, by the network analyzer, at least one error condition pertaining to: invalid Max-forwards, invalid CSeq number, invalid content length, and invalid content-type in at least one protocol message received from the first network node based on the comparison; and performing, by the network analyzer, 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, wherein performing the corrective measure by the network analyzer comprises: adjusting a configuration setting that comprises: nodal tables, addresses and/or policies in the first network node corresponding to the at least one error condition in the at least one protocol message; and generating the at least one protocol message with valid data fields or valid extensions for a subsequent communication session based on the adjusted configuration setting in the first network node. adjusting a configuration setting that comprises: nodal tables, addresses and/or policies in the first network node corresponding to the at least one error condition in the at least one protocol message; and generating the at least one protocol message with valid data fields or valid extensions for a subsequent communication session based on the adjusted configuration setting in the first network node.
