摘　　要：针对大容量OLT系统高可用性能的要求,以Heartbeat与Drbd结合为研究对象,使系统具有热备高可用的同时又具有同步文件的功能。在此讨论了Heartbeat与Drbd结合应用的基本原理及可行性,实现了其应用于大容量OLT的热备系统中,改进了切换的速度,增加其稳定性。实际测试表明Heartbeat与Drbd能很好地应用于大容理OLT中,系统快速稳定,满足应用系统高可用性。并基于开源Linux-HA项目下的免费软件使得降低成本,使其拥有更高的市场竞争力。Taking the combination of Heartbeat with Drbd as a research object, the basic principles and feasibility of joint application of Heartbeat and Drbd are discussed to meet the high-availability requirement of large-capacity OLT system, and make the system to have hot standby high-availability and the function of the synchronization file. The joint application of Heartbeat and Drbd large-capacity was realized in thermal system with large-capacity OLT. The application of the technology improved switching speed and system stability. Actual tests show Heartbeat and Drbd can be well applied to the large-capacity OLT , the system is rapid and stable, and can meet the high availability of application system. The free software based on the open source Linux-HA project made the system cost reduced, and made the system to have a higher market competitiveness.
