In　the　large　scale　network,　a　logical　synchronous　network　should　be　setup　automatically　at　running　time　in　order　to　synchronize　the　clocks　of　the　nodes.　To　put　nodes　into　logical　synchronous　network　properly,　a　efficient　synchronous　resource　should　be　selected.　The　nodes＇　clocks　precision,　stability,　capability,　real-time　loads,　and　the　structure　of　the　network　are　key　aspects　for　selecting　synchronous　resources.　Strategy　Based　Synchronous　Resource　Selection　Algorithm　(abbreviated　as　SS)　makes　its　decision　by　measuring　the　real-time　performance　of　the　nodes　and　the　given　stratum.　The　experiments　show　that　SS　can　select　the　proper　resource　providers　from　the　intended　candidates　and　has　better　performance　than　the　usual　FIFS　algorithm.
