The communication channel is a part of the protection system and enables fulfillment of the protection system requirements. Generally, communication technologies evolve much faster than protective relaying technologies. The current shift towards packet-based data switching, such as Ethernet communications, presents new challenges as characteristics of new packet-based communications are less deterministic than those of traditional Time Division Multiplexing (TDM). By its nature performance of packet-based switching depends on resource availability, while TDM communications utilize dedicated resources.

As protection engineers face the transition to Ethernet-based communications, understanding their operation and expected performance becomes crucial for achieving required reliability of the protection systems.
