MuxComp - A New Architecture to Improve VoIP Bandwidth Utilization

Voice over IP (VoIP) is expected to be the key of the communication industry in near future. Inefficient bandwidth usage by VoIP consumed the network bandwidth. The problem of inefficient bandwidth usage is handled by several techniques such as silence suppression, packets multiplexing, and voice compression. This work proposed new architecture to save network bandwidth for VoIP. We called the new architecture MuxComp. MuxComp, combines packets multiplexing and voice compression. Whereas, multiplexing the voice packets reduce the overheads, furthermore give the opportunity to compress the packets again. The MuxComp architecture consists of two entities. The MuxCmp entity is VoIP gateway in the sender side, which performs the multiplexing and compression processes to the packets and sends them to their destinations. The DCmpDMux entity is VoIP gateway in the receiver side, which performs the reverse processes of MuxCmp through de-compression and de-multiplexing the packets. Furthermore, this work is considered the size of the multiplexed packets, whereas the size must not exceed the network Maximum Transfer Unit (MTU), therefore avoiding the fragmentation delay through the network.
