Is it possible to handle “peer-to-peer” communications using the SMP Gateway?
Unfortunately, the term “peer-to-peer communications” does not always mean the same thing in all contexts. Peer-to-peer communications can mean the exchange of information between IEDs, between SMP Gateways, or between control centers. When response times are not critical (tens or hundreds of milliseconds), the SMP Gateway can support any of these three functionalities in a number of ways. However, in the protection world, peer-to-peer communications can also mean the very fast exchange of information for protection reasons (typically in the order of a few milliseconds). The SMP Gateway cannot achieve such a response time. For these applications, direct inter-IED communications such as the SEL bit mirroring technology or the IEC 61850 proposed GOOSE protocol must be used.
