  2. G.729 - Wikipedia

    en.wikipedia.org/wiki/G.729

    Because of its low bandwidth requirements, G.729 is mostly used in voice over Internet Protocol (VoIP) applications when bandwidth must be conserved. Standard G.729 operates at a bit rate of 8 kbit/s, but extensions provide rates of 6.4 kbit/s (Annex D, F, H, I, C+) and 11.8 kbit/s (Annex E, G, H, I, C+) for worse and better speech quality ...

  3. Network traffic measurement - Wikipedia

    en.wikipedia.org/wiki/Network_traffic_measurement

    Some tools measure traffic by sniffing and others use SNMP, WMI or other local agents to measure bandwidth use on individual machines and routers. However, the latter generally do not detect the type of traffic, nor do they work for machines which are not running the necessary agent software , such as rogue machines on the network, or machines ...

  4. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.

  5. Voice over IP - Wikipedia

    en.wikipedia.org/wiki/Voice_over_IP

    The prices of extensions on VoIP are lower than for PBX and key systems. VoIP switches may run on commodity hardware, such as personal computers. Rather than closed architectures, these devices rely on standard interfaces. [21] VoIP devices have simple, intuitive user interfaces, so users can often make simple system configuration changes.

  6. Quality of service - Wikipedia

    en.wikipedia.org/wiki/Quality_of_service

    Commercial VoIP services are often competitive with traditional telephone service in terms of call quality even without QoS mechanisms in use on the user's connection to their ISP and the VoIP provider's connection to a different ISP. Under high load conditions, however, VoIP may degrade to cell-phone quality or worse.

    Over 30% of U.S. companies use Voice over Internet Protocol (VoIP) phone systems. Many switch from conventional services to realize the benefits of VoIP, including lower costs, operational ...

  8. Packet delay variation - Wikipedia

    en.wikipedia.org/wiki/Packet_delay_variation

    As long as the bandwidth can support the stream, and the buffer size is sufficient, buffering only causes a detectable delay before the start of media playback. However, for interactive real-time applications, e.g., voice over IP (VoIP), PDV can be a serious issue and hence VoIP transmissions may need quality-of-service –enabled networks to ...
