Estimation of Transmission Bandwidth for VoIP Signals over IP Packet Transmission Network using Capacity Computing Method

Abstract

The traditional telephone network is the required transmission bandwidth of 64kbit/s. The so-called VoIP is an IP packet transmission network as a transmission platform, simulated voice signal compression, packaging and continuous special processing, which can use the connectionless UDP protocol for transmission. Sending voice signals over an IP network requires several components and functions. The simplest form of a network consists of two or more devices with VoIP capabilities connected through an IP network. In this paper, a smart estimation of transmission bandwidth for VoIP signals over IP packet transmission network using capacity computing method. A speech network establishes a physical connection between communication endpoints (a line) and transmits encoded signals between the endpoints. Unlike circuit switching networks, IP networks do not create connections. It requires data to be placed into variable long data reports or packets, and then address and control information must be sent for each datagram and sent over the network to the destination.
