Abstract

There are many circumstances in which delay sensitive traffic and a delay insensitive traffic share an access to a telecommunications network. TCP/IP is well suited for proper delivery of the delay insensitive traffic whereas the delay sensitive traffic uses UDP/IP protocol. When a delay sensitive traffic in UDP/IP packets is in progress, ACK delay parameter in TCP/IP protocol can be adjusted so that UDP packets can be inserted among TCP packets to reduce collision and end-to-end delay of UDP packets.
