Discussion on Engineering Optimization Solutions for Broadband Network Expansion in Radio and Television Systems

摘要

伴随智慧家居普及、超高清视频流媒体普及以及各类政企线上办公业务落地，城乡居民宽带流量需求迎来快速增长周期。目前大量存量广电宽带网络，普遍存在带宽预留不足、光路传输损耗偏高、流量调度机制僵化等现实问题。行业内传统的扩容手段多为单纯后台带宽抬升，并未触及物理链路与组网架构的核心短板，无法彻底解决晚间高峰网速跳水、数据丢包、终端速率不达标等频发故障。本文依托县域广电网络一线改造、运维实测经验，梳理现有组网、硬件设备、资源分配层面的实际缺陷，从架构精简、链路提质、硬件迭代、智能调度四个维度搭建优化方案。

Abstract

With the widespread adoption of smart home technologies, the proliferation of ultra-high-definition video streaming services, and the implementation of various online office solutions for government and enterprise sectors, the broadband data traffic demand among urban and rural residents has entered a period of rapid growth. Currently, a large number of existing radio and television broadband networks face common practical challenges, such as insufficient bandwidth reservation, relatively high optical fiber transmission loss, and rigid traffic scheduling mechanisms. Traditional expansion methods within the industry often rely solely on increasing backend bandwidth without addressing the core weaknesses of physical links and network architecture, thus failing to resolve recurring issues such as drastic drops in network speed during evening peak hours, data packet loss, and failure of terminal devices to meet required speeds. Drawing upon field renovation experience and operational testing data from county-level radio and television networks, this paper identifies the actual deficiencies at the network architecture, hardware equipment, and resource allocation levels, and proposes an optimization framework based on four key dimensions: architectural simplification, link quality enhancement, hardware iteration, and intelligent scheduling.
