摘要

在COVID-19大流行封锁期间，对IP电话等电信服务的需求急剧增加。IP电话应得到加强，以提供预期的质量。在IP电话中需要研究的问题之一是带宽利用率。IP电话产生非常小的语音样本，附加到一个大的数据包头。IP电话的报头占用了分配给IP电话的相当一部分带宽。这会浪费网络带宽，影响IP通话质量。本文提出了一种机制(称为Smallerize)，可以减少语音样本和报头所消耗的带宽。这是通过在一个报头中组装许多IP电话数据包并使用报头的字段来携带语音样本来实现的。有几个指标被用来衡量Smallerize机制的成就。与典型机制相比，调用次数增加了245.1%。使用G.28编解码器，带宽节省也达到68%。因此，小型化是提高IP电话带宽利用率的一种可能的机制。

Enhancing Bandwidth Utilization of IP Telephony Over IPv6 Networks

The demand for the telecommunication services, such as IP telephony, has increased dramatically during the COVID-19 pandemic lockdown. IP telephony should be enhanced to provide the expected quality. One of the issues that should be investigated in IP telephony is bandwidth utilization. IP telephony produces very small speech samples attached to a large packet header. The header of the IP telephony consumes a considerable share of the bandwidth allotted to the IP telephony. This wastes the network's bandwidth and influences the IP telephony quality. This paper proposes a mechanism (called Smallerize) that reduces the bandwidth consumed by both the speech sample and the header. This is achieved by assembling numerous IP telephony packets in one header and use the header's fields to carry the speech sample. Several metrics have been used to measure the achievement Smallerize mechanism. The number of calls has been increased by 245.1% compared to the typical mechanism. The bandwidth saving has also reached 68% with the G.28 codec. Therefore, Smallerize is a possible mechanism to enhance bandwidth utilization of the IP telephony.
