Packet sniffing software is designed to help analyze these collected packets because even a small amount of data can result in thousands of packets which can be hard to navigate. There are many powerful tools out there that collect network traffic activity and most of them use pcap (Unix-like systems) or libcap (Windows systems) at their core to do the actual collection.

Zaijun, W., Minqiang, H.: Research on a substation automation system based on IEC 61850. IEC 61850 Communication Networks and System in Substation Automation, The experimental results show that our packet analyzer outperforms the existing Wireshark program significantly in terms of the packet analysis time. Our packet analyzer is implemented with FLA (fast later access) and DPI (deep packet inspection) features as a network application analyzing only IEC 61850 communication protocols. Since the amount of packets is massive in IEC 61850, we need to develop a packet analyzer for analyzing communications between the substation automation system server and client, which demands real-time operation and high reliability. A substation automation system consists of a station, bay, and process level. This paper proposes the design and implementation of a packet analyzer dedicated to IEC 61850 for effectively analyzing standard protocols for IEC 61850 communication networks. In the aspect of stable operation for smart grid, the combination of communication technology is an important component.
