Abstract:
1. A method for analysis of a plurality of network transactions in a communication network consisting of a first set of nodes characterized by monitoring a plurality of sub-transactions constituting the network transactions, the method comprising processor implemented steps of: classifying a second set of nodes, hosting the sub-transactions, into a first set of layers, each layer containing a third set of nodes with similar functionalities; capturing network transaction data at each node of each classified first set of layers and storing the network transaction data in a repository in the network in test environment; generating and storing a plurality of transaction flow signatures depicting hierarchical flow of the network sub-transactions amongst the classified layers and associated performance at each node based on the captured network transaction data in the test environment; capturing a network transaction data of at least one network transaction in the network in a real time environment from the first set of layers facilitating at-least one sub-transaction of the network transaction; identifying at least one transaction flow signature from the stored transaction flow signatures matching the network transaction by correlating network parameters and transaction parameters; and generating a diagnostic report indicating a layer-wise nodal anomalies and associated performance constraints in the communication network for the network transaction analyzed through identified transaction flow signature using metrics comparisons for multiple layers, multiple sessions and multiple individual layers.
