After storing information, its neighbours' server list will be searched, neighbours' server update of attenuation type is carried out by hop count.For example, edge
Server notifies the neighbours' server update for being 1 away from its hop count to store information first, since these neighbours' servers are nearest,
The data that Edge Server this time updates will be replicated on these neighbours' servers and be updated by 100%；Then, away from its hop count
For 2 neighbours' server, 50% new data will be replicated and updated；And so on, constantly decaying, sets a threshold value 5%, when
When the data volume of the update is 5% or less threshold value, neighbours' server will no longer replicate and more new data.
