System and method for identifying nodes with packet loss in a wireless communication network. The method comprises a central probe server—establishing a TWAMP session with a plurality of nodes. The central probe server probes the plurality of nodes for packet loss for a time duration ΔT and categorizes each of the plurality of nodes as one of violator node and non-violator node. A sectionalisation module retrieves a topology of the at least one violator node. The central probe server probes at least one neighboring node of the at least one violator node for packet loss for the time duration ΔT. The sectionalisation module identifies the at least one violator node as one of a silo node and a daisy chain node based on the probe of the at least one neighboring node.
