Skydive e bonts'a topology ea marang-rang ka ho amohela liketsahalo tsa marang-rang ho tsoa ho baemeli ba Skydive. Na u kile ua ipotsa hore na u ka eketsa kapa ho bontša joang ka har'a setšoantšo sa topology diagram likarolo tsa marang-rang tse ka ntle ho marang-rang a moemeli oa Skydive kapa lintho tse seng tsa marang-rang tse kang TOR, polokelo ea data, joalo-joalo. Ha ho hlokahale hore u tšoenyehe ka seo ka lebaka la molao oa Node API.
Ho tloha ka mofuta oa 0.20, Skydive e fana ka API ea molao oa Node e ka sebelisoang ho theha li-node tse ncha le lithako le ho ntlafatsa metadata ea li-node tse teng. Node rule API e arotsoe ka li-API tse peli: node rule API le edge rule API. Node Rule API e sebelisetsoa ho theha node e ncha le ho ntlafatsa metadata ea node e teng. The Edge rule API e sebelisetsoa ho theha moeli pakeng tsa li-node tse peli, ke hore. e kopanya li-node tse peli.
Ho blog ena re tla bona linyeoe tse peli tsa ts'ebeliso, e 'ngoe ea tsona ke karolo ea marang-rang e seng karolo ea marang-rang a skydive. Khetho ea bobeli ke karolo e seng ea marang-rang. Pele ho moo, re tla sheba mekhoa e meng ea mantlha ea ho sebelisa Topology Rules API.
