Webb10 mars 2008 · Token passing is a channel access technique used in several communication networks. Among them, one of the most effective solution for supporting both real-time traffic (synchronous messages) and non real-time traffic (asynchronous messages), is the so-called timed-token protocol. Webb22 feb. 2024 · Token passing protocols are also scalable, but they don’t work well for networks with a lot of data to transmit since the token has to circulate through all the devices on the network. Reservation-based protocols are the least scalable since they require a lot of coordination between devices and can lead to wasted transmission slots.

"WebbARCNET’s token-passing protocol provides this timeliness. Fieldbus messages are generally short. ARCNET packet lengths are variable from 0 to 507 bytes with little overhead and, coupled with ARCNET’s high data rate, typically 2.5 Mbps, yields quick responsiveness to short messages.
