“…It is still an issue that the indirect factor of TCP effects the quality of multimedia communication. In literature, there are a number of studies that have been conducted on TCP and video communication [1], UDP and TCP in signaling messages [7], and transport protocol performance in multimedia communication [12]. In sum, TCP is used for signaling and UDP for media transfer.…”

“…Multimedia communication has become a daily requirement through the continuous increase of user communication via social media, education, businesses, applications, among others. To control multimedia communication there should be a control system that can handle video communication, video conferencing, and video streaming [1]. The Internet Protocol multimedia subsystem (IMS) is an architecture that has been used to work and handle the most usable services and applications on the Internet [2].…”

The IP Multimedia Subsystem (IMS) has the major architectural framework to be involved in the Next Generation Network. IMS works to bridge multimedia communication among a variety of applications over the Internet. IMS bears its multimedia signals and streams through different means of transport protocols; TCP, UDP, and SCTP. TCP is a connection-oriented protocol that provides reliable data delivery and congestion control. To setup connection with TCP, IMS entities require extra operations to be completed, and those operation processes called (worker process) cost the multimedia server extra overload and delay. This paper investigates the indirect impacts of TCP connections that result from the Call Session Control Function (CSCF) servers when dealing with video communication using a local network setup with wired connection. Two parameters are evaluated in the experiment: CPU usage and response time, in two different scenarios. The experimental results show that the outbound scenario performs better than the inbound scenario due to the extra operations required to setup new TCP connection for the inbound.
