TDS adds flexibility and capacity to circuit-switched networks but requires precise synchronization among nodes and propagating datagrams.

Datagrams are formatted according to schedules that depend on [[quality of service]] and availability of switching nodes and physical links. In respect to circuit switching, the added time dimension introduces additional complexity to network management. Like circuit switching, TDS operates without buffers and header processing according to the [[pipeline forwarding]] principle; therefore an all optical implementation with [[optical fiber]]s and [[optical switch]]es is possible with low cost. The TDS concept itself pervades and is applicable with advantage to existing data switching technologies, including [[packet switching]], where packets, or sets of packets become the datagrams that are routed through the network.{{cn|reason=doubtful that concept could work on packet switching|date=February 2023}}

TDS has been invented in 2002 by Prof. Mario Baldi and Prof. [[Yoram Ofek]] of Synchrodyne Networks that is the assignee of several patents issued by both the [[United States Patent and Trademark Office]] and the [[European Patent Office]].<ref>http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=0&f=S&l=50&TERM1=synchrodyne&FIELD1=ASNM&co1=AND&TERM2=&FIELD2=&d=PTXT</ref>
