Node device operation method, work status switching apparatus, node device, and medium

A first node device comprising one or more processors, memory coupled to the one or more processors and a plurality of programs stored in the memory, wherein the first node device is a member of a network system of node devices, and the plurality of programs, when executed by the one or more processors, cause the first node device to perform a plurality of operations comprising:

• receiving, by the first node device, voting requests from a plurality of second node devices, a quantity of the plurality of second node devices being greater than half of a quantity of node devices among the network system of node devices;
• when the first node device operates in a leader state, obtaining, by the first node device, cycle length information and latest log indexes from the voting requests of the plurality of second node devices;
• and
• switching, by the first node device, a work status of the first node device from the leader state to a follower state or a candidate state when (i) all the cycle length information in the voting requests of the plurality of second node devices is greater than cycle length information of the first node device and (ii) all the latest log indexes in the voting requests of the plurality of second node devices are not less than a latest log index of the first node device.

A non-transitory computer readable storage medium storing a plurality of machine readable instructions in connection with a first node device having one or more processors, wherein the first node device is a member of a network system of node devices, and the plurality of machine readable instructions, when executed by the one or more processors, cause the first node device to perform a plurality of operations including:

• receiving, by the first node device, voting requests from a plurality of second node devices, a quantity of the plurality of second node devices being greater than half of a quantity of node devices among the network system of node devices;
• when the first node device operates in a leader state, obtaining, by the first node device, cycle length information and latest log indexes from the voting requests of the plurality of second node devices;
• and
• switching, by the first node device, a work status of the first node device from the leader state to a follower state or a candidate state when (i) all the cycle length information in the voting requests of the plurality of second node devices is greater than cycle length information of the first node device and (ii) all the latest log indexes in the voting requests of the plurality of second node devices are not less than a latest log index of the first node device.
