1.高稳定高可靠性网络改造的要求1.1网络的高可靠性、高稳定性在进行有线电视网络的双向改造时,应将网络的可靠性、稳定性放在首位。这是因为双向有线电视网络不是单一的、广播形式的网络,而是一个交互式的综合信息网络,其可靠性的优劣直接关系到网络运营的成败。在进行双向网络改造时,首先必须遵循高可靠性、高稳定性的原则。主要应该包括以下几个方面的要求:(1)网络设备运行、元器件的稳定性要有显著的提高。(2)设备内关键部件应有多余备份,因为部件的多余备份是提高设备可靠性的重要措施。(3)必须建立高效的网络管理系统。真正实现对网络设备的有效监控,充分满足网络高稳定高可靠性的要求。(4)网络设备的安全性(高稳压、接地、防雷、抗浪涌)与系统安全
1 high stability and high reliability network transformation requirements 1.1 network of high reliability, high stability in the two-way cable network transformation, the network should be the reliability and stability of the first place. This is because the two-way cable television network is not a single, broadcast network, but an interactive integrated information network, the reliability of which is directly related to the success or failure of network operations. In the two-way network transformation, we must first follow the principle of high reliability, high stability. Mainly include the following requirements: (1) network equipment operation, the stability of components must be significantly improved. (2) There should be redundant backup of the key components in the equipment, because redundant backup of components is an important measure to improve the reliability of the equipment. (3) must establish an efficient network management system. Truly realize the effective monitoring of network equipment to fully meet the network requirements of high stability and high reliability. (4) network equipment security (high voltage, ground, lightning, surge) and system security
