Generic substation Events (GSE) is a control model defined as per IEC 61850 which provides a fast and reliable mechanism of transferring event data over electrical substation networks. This provides facility to transfer the same event message to multiple physical devices using multicast / broadcast services. GSE control model is further subdivided into GOOSE (Generic Object Oriented Substation Events) and GSSE (Generic Substation State Events).


XXX - add a brief description of GOOSE history

Protocol dependencies

  • GOOSE data is directly embedded into Ethernet data packets and works on publisher-subscriber mechanism on multicast or broadcast MAC addresses.

  • GOOSE also uses VLAN and priority tagging as per IEEE 802.1Q to have separate virtual network within the same physical network & setting high priority for the message.

Example traffic

XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).


The GOOSE/GSE dissector is created using the Asn2wrs compiler.

Preference Settings

(XXX add links to preference settings affecting how GOOSE/GSE is dissected).

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

Display Filter

A complete list of GOOSE/GSE display filter fields can be found in the display filter reference
