Poznámky
Vyšší čísla označují vyšší prioritu, takže kanál s prioritou 50 má vyšší prioritu než kanál s prioritou 25. Kanál domény napříč aplikacemi má prioritu 100.
Kanály klientů s vyšší prioritou mají první šanci připojit se ke vzdálenému objektu určenému adresou URL nebo konkrétním datovým záznamem ObjRefkanálu z .
U kanálů serveru určuje priorita pořadí, ve kterém se data kanálu zobrazí v objektu ObjRef, což zase ovlivňuje pořadí, ve kterém se klienti pokusí připojit k objektu serveru. Pokud server naslouchá na kanálu HTTP s prioritou 50 a kanálu TCP s prioritou 25 a klient zaregistroval kanál HTTP i TCP, klient použije kanál HTTP k komunikaci se serverem.
