Abstract
[Problem to be Solved] Optimizing a route of time synchronization in a network including apparatuses with different types of precision classes. [Solution to the Problem] A time transmission system includes BC nodeswith different types of apparatus performances, and multiple routes of PTP packets from GM nodesandto a BC nodevia the BC nodeare present. Each BC nodelocated upstream on a route performs notification of performance information indicating its apparatus performance to the BC nodelocated downstream with respect thereto. The BC nodeincludes a determination index calculation unitthat calculates a determination index for each route by referencing the performance information notified from the BC nodeslocated upstream on each route, and a route selection unitthat selects a route for transmitting and receiving PTP packets from multiple routes of PTP packets to the BC node, based on the calculated determination index for each route.
