The network delay weight selection mechanism is then performed as follows:
(a) setting sequence numbers according to the sequence of 1-99999, sequencing all the computing nodes according to the initialization sequence of the computing nodes, wherein the sequence number of the computing node which is initialized earliest is 1, and the larger the distribution sequence number at the initialization later is, the larger the distribution sequence number is, the corresponding weight needs to be taken as the computing node at the same time;
(b) cleaning the computing nodes, removing unreachable computing nodes, and judging that the computing nodes are unreachable according to the requirement of the private cloud service system that the network delay exceeds 3 seconds;
(c) according to the heartbeat mechanism of the computing nodes, network delay of communication between each computing node and other nodes is counted, summed and multiplied by the weight to obtain the network delay weighted value of each normal computing node;
the private cloud system node collects network communication conditions with other nodes every 10 seconds according to a plan through a heartbeat mechanism, and records network delay. Before network delay weight calculation is carried out on n-1 computing nodes, the computing nodes with poor network environment are cleaned, and the rest m computing nodes participate in arbitration. The network delay statistics of m computing nodes are as follows, D (i, j) represents the network delay from computing node i to computing node j, and the network delay from 1 to m is as follows:
D(1,2)D(1,3)D(1,4)…D(1,m)

(d) and selecting the computing node with the minimum network delay weighted value as a management node.
Acquisition set (Total)1,Total2,Total3…Totalm) Selecting Total with minimum network delay weighted valueminAs a management node.
