Apparatus and method for detecting network congestion based on destination node

Abstract

An apparatus and a method for detecting network congestion based on a destination node are provided. To elaborate, the apparatus may include: a physical information extraction unit that extracts physical information of an electrical signal received through an antenna of the destination node; a MAC information extraction unit that extracts a size of a MAC frame payload from a MAC frame on the basis of the extracted physical information; a TCP information extraction unit that extracts a size of service data included in the MAC frame payload; a data size comparison unit that compares the size of the MAC frame payload with the size of the service data and generates comparison result data; and a congestion detection unit that receives the comparison result data, compares the comparison result data with a predetermined threshold value, and determines presence or absence of network congestion.

Dependencies are inferred from the claim text.
