Application of Heartbeat and Drbd in large-capacity OLT

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.
