Iyo IETF (Internet Engineering Task Force) komiti, iyo inovandudza Internet protocol uye zvivakwa, yakagadzira RFC ye "DNS Push Notifications" maitiro uye yakaburitsa iyo yakabatana yakatarwa pasi pechiziviso. . Iyo RFC yakagamuchira chimiro che "Proposed Standard", mushure mezvo basa richatanga kupa RFC mamiriro eiyo dhizaini mwero (Draft Standard), izvo zvinoreva kudzikamisa kwakakwana kweprotocol uye kufunga nezvese zvataurwa.
Iyo "DNS Push Notification" nzira inobvumira mutengi kuti agamuchire zviziviso kubva kuDNS server nezve shanduko mumarekodhi eDNS, pasina chikonzero chekuvavhota nguva nenguva. Push zviziviso zvinogadziriswa uchishandisa TCP yekufambisa chete, ine nzira yekutaurirana yakachengetedzwa uchishandisa "TLS pamusoro peTCP". Sevha ine mvumo yeDNS inogona kugamuchira TCP kubatana kubva kuDNS Push Notification vatengi vanotumira zvikumbiro zvekunyorera kune chaiwo mazita nemhando dzeDNS rekodhi. Mushure mekugamuchira chikumbiro chekunyorera, sevha pachayo inotumira zviziviso kumutengi nezve shanduko mumarekodhi akataurwa.
Mutengi anoona kuti DNS Push Notification inotsigirwa nekutumira zvakajairika DNS query inotarisa kuti SRV rekodhi "_dns-push-tls._tcp.zone_name" iriko inonongedza kumaseva eDNS ari kushandira zvakanyoreswa. Mutengi anogona zvakare kunyorera kune rekodhi isipo, uye sevha inofanirwa kuzivisa mutengi kana imwe ikaonekwa mune ramangwana. Zviziviso zvinotumirwa chete kana paine TCP yekubatanidza yakagadzwa neseva uye haina kugadzirwa kuti itevedze maawa makumi maviri nemana pazuva, mazuva manomwe pasvondo - kunyoreswa kunofanirwa kudzimwa kana kusingashande (semuenzaniso, kana mudziyo ukapinda mune yekumira mode) uye inoshandiswa chete kana paine kudiwa kwakananga kwekutarisa shanduko mune yekurarama modhi. Yenguva dzose DSN zvikumbiro zvinogona zvakare kutumirwa kuburikidza neTCP chiteshi chakagadzirirwa Push zviziviso.
