synchronous protocol

synchronous protocol

A communications protocol that controls a synchronous transmission, such as bisync, SDLC and HDLC. Contrast with asynchronous protocol.

The routers also feature synchronous protocol support for retail and financial devices such as automated teller machines (ATMs) and lottery machines.
For any of these problems, one possible solution would be to add a dedicated microprocessor to handle the overhead, convert EBCDIC character code to ASCII, handle a synchronous protocol on one side and an async interface on the other and multiplex terminals.
Comparing with synchronous protocols, the energy curve reaches the dashed horizontal line early.
In contrast, asynchronous MAC protocols, such as B-MAC [4], X-MAC [1], and RI-MAC [5], have higher energy efficiency than synchronous protocols. These protocols are using the preamble sampling, instead of additional synchronized control frames.
The MAC protocols equipped the mechanism which has been proven to outperform the state-of-the-art of traditional sender-initiated protocols and the synchronous protocols [16].
Second, while is possible to design asynchronous protocols with safety properties similar to those of the synchronous protocols, the timeliness properties satisfied by asynchronous protocols are much weaker; the delays with which processes learn of new updates, joins, and failures are bounded only when certain stability conditions hold.
True statistical multiplexing of synchronous protocols is available only from the more-sophisticated multiplexer vendors.
Once again, it's a matter of evaluating your internal message-sending needs to determine whether low-speed protocol, such as those supporting teleprinters, are needed; or synchronous protocols supporting higher-speed data transfer are preferred.
