Högre tal anger högre prioritet, så en kanal med prioritet 50 har högre prioritet än en kanal med prioritet 25. Domänkanalen mellan program har en prioritet på 100.

Klientkanaler med högre prioritet får den första chansen att ansluta till ett fjärrobjekt som anges av en URL eller en viss kanaldatapost från en ObjRef.

För serverkanaler anger prioriteten i vilken ordning deras kanaldata ska visas i en ObjRef, vilket i sin tur påverkar i vilken ordning klienter försöker ansluta till serverobjektet. Om servern lyssnar på en HTTP-kanal med prioritet 50 och en TCP-kanal med prioritet 25 och klienten har registrerat både en HTTP- och TCP-kanal använder klienten HTTP-kanalen för att prata med servern.
