Lkcc , a linux kernel concurrent communication mechanism , uses object transfer protocol to send and receive data 。 in order to improving system processing capability and to response client requests , session mechanism is changed ; because a great of source have several copy , multi - send is added ; because dps often has great load , some emergent message cannot be send duly ; capability of system is depressed , message pri is added to lkcc 為了改善系統(tǒng)的性能和滿足用戶的需求,將原來(lái)otp協(xié)議中會(huì)話的一一應(yīng)答改成了組應(yīng)答方式;由于dps系統(tǒng)的資源存在多個(gè)副本,所以在lkcc中加入了組播功能;又因?yàn)楫?dāng)系統(tǒng)繁忙時(shí),某些緊急數(shù)據(jù)得不到優(yōu)先發(fā)送,降低了系統(tǒng)的性能,所以本文又實(shí)現(xiàn)了對(duì)緊急數(shù)據(jù)的優(yōu)先發(fā)送。
