In the last years the multimedia traffic on IP networks has increased significantly. According to Cisco, the video contents are expected to reach 82% of the total IP traffic by 2022. The explosion of video on demand and real time/live event videos causes several issues for Telco networks, such as increased delay in content delivery, frequent congestions and service unavailability. In this paper we analyse an integration model between the broadcaster’s network and the Telcos’ fixed access networks. In particular, contents from the distribution network of broadcasters are directly injected into the central offices of Telco’s network. This integrated architecture allows offloading the core and metro segments of the Telco network and, at the same time, it enables broadcasters to provide contents with reduced latency and to avoid typical inconveniences in Telco’s network. Performance analysis is carried out in terms of the required transmission power per multiplex. As shown in the paper, the considered integrated network architecture can achieve cost savings in terms of transmission power per multiplex. The possibility of improving current FTTC access networks for supporting broadcast by means of sharing of multiple copper pairs has been also investigated.

为实时/现场活动集成广播和电信接入网络

在过去几年中，IP 网络上的多媒体流量显着增加。据思科称，到 2022 年，视频内容预计将达到总 IP 流量的 82%。视频点播和实时/直播事件视频的爆炸式增长给电信网络带来了几个问题，例如内容交付延迟增加、频繁拥塞和服务不可用。在本文中，我们分析了广播公司网络和电信公司固定接入网络之间的集成模型。特别是，来自广播公司分发网络的内容直接注入电信公司网络的中心办公室。这种集成架构允许卸载电信网络的核心和城域网段，同时，它使广播公司能够以减少的延迟提供内容，并避免电信网络中的典型不便。根据每个多路复用所需的传输功率进行性能分析。如论文所示，所考虑的集成网络架构可以在每个多路复用的传输功率方面实现成本节约。还研究了通过共享多个铜线对来改进当前 FTTC 接入网络以支持广播的可能性。
