The method that present embodiment provides, determine the purpose registrar by registrar according to the EPC in the Item Information, the purpose registrar is determined the purpose information server according to the EPC in the Item Information, the final storage that realizes the multidate information in the Item Information, need not arrange a large amount of resolution servers, save hardware resource.
At first introduce the network architecture of above-mentioned stores information below.
This Internet of Things comprises registrar and information server.Wherein, the static information of registrar stores comprises the keyword of representing article characteristics, as attribute keyword of article etc.The multidate information of information server stores article is as the current state of article, position etc.Registrar can adopt the higher equipment of stability, guarantees not lose for the higher static information of reliability requirement, and information server then can adopt cost and the lower equipment of stability, and storage is for the lower multidate information of reliability requirement.Between the registrar of this network, between the information server, link to each other by wide area network between registrar and the information server.
This network is a hierarchical network, is divided into upper layer network and lower floor's network.Upper layer network is made up of all registrar, and lower floor's network is made up of all information servers.This lower floor's network is divided into the experimental process network, concrete, sub-network is made up of at least one registrar of upper layer network and one or more information servers of lower floor's network, and any two sub-networks are non-intersect, a server only belongs to a sub-networking, and promptly a server can not belong to two sub-networks simultaneously.Wherein, the registrar in the sub-network provides interface with the upper layer network information interaction for information server.
Concrete, each registrar has one or more upper layer logic addresses that are used for upper layer network, and each upper layer logic address has a upper layer logic address table, is used to store the corresponding relation of adjacent registrar logical address in upper strata and IP address; Each registrar also has lower floor's logical address that is used for lower floor's network simultaneously, this lower floor's logical address has lower floor's logical address table, is used to store the corresponding relation of adjacent information server logical address of the lower floor that is in same sub-network with it and IP address.
Concrete, each information server has one or more lower floor's logical addresses that are used for lower floor's network, each lower floor's logical address has lower floor's logical address table, is used to store the corresponding relation of adjacent information server logical address of the lower floor that is in same sub-network with it and IP address; Each information server also has at least one IP address that is in the registrar in the same sub-network with it simultaneously.
The logical address of registrar is distributed specific as follows: as the node in the upper layer network, each registrar has the upper layer logic address of the individual N bit of i (i＞=1), as the node in the sub-network, each registrar has lower floor's logical address of an identical M bit, and promptly M individual 0.Wherein, N is the logical address bit of upper layer network, represents that this network logical address space is 2
N, M is the logical address space of lower floor's sub-network, represents that this network logical address space is 2
M, N is predefined bigger value, can satisfy in the upper layer network and carry out the needs that logical address is distributed because of registrar increases.In the upper layer network that initially has n registrar, on average each thing registrar preassignment is about
Individual upper layer logic address makes and all can locate a registrar according to each upper layer logic address.For example, upper layer network is made up of 10000 registrar, and during upper layer logic address bit position N=14, then the upper layer logic address space is 2
14=16384, bring above-mentioned formula into, 16384 divided by 10000, equal 1.6384, round downwards 1.6384 again, be that value is 1, then in 10000 registrar, average each registrar can have 1 14 logical address at least, also has 6384 logical address residue so, then these 6384 logical addresses is distributed the registrar of each existing logical address, then last, 16384 logical addresses are distributed to server in the network, and can obtain: 6384 registrar have 2 upper layer logic addresses, and all the other 3616 registrar have 1 upper layer logic address.The logical address of information server is distributed: as the node in the sub-network, each information server has lower floor's logical address of the individual M bit of j (j＞=1).Wherein, M is predefined bigger value, can satisfy in any one sub-network and carry out the needs that logical address is distributed because of the increase of information server.If certain sub-network has one or several registrar, a m information server, then each information server preassignment is about
Individual lower floor logical address (lower floor's logical address of complete 0 bit is shared by the registrar in this sub-network) makes and all can locate an information server according to each lower floor's logical address.For example, lower floor's network is made up of 10000 information servers, and during the logical address bit M=14 of lower floor, lower floor's logical address space is 2
14=16384, then with reference to registrar logical address distribution method, the information server logical address can be assigned as: 6383 information servers have 2 lower floor's logical addresses, and all the other 3617 information servers have 1 lower floor's logical address.
Adjacent server is the server that satisfies certain logical address distance in this network, and the distance of logical address i.e. the XOR value of two logical addresses, and it is far away more to be worth big more distance, is worth that small distance is near more more.
Concrete, according to different logical addresses, the corresponding different neighbors of each node is the set of adjacent server, according to certain logical address A of node E, and the set of the neighbors of node E
Be defined as k the node that satisfies following condition, k is predefined value, and this condition is:
In any logical address of having less than other nodes of the distance of certain logical address of node and logical address A and the distance of logical address A.
The maintenance of registrar node relationships: as the node in the upper layer network, for each logical address Au, each registrar R has a upper strata neighbor node table TR (Au), this list records in upper layer network, according to logical address Au, the mapping of the logical address of the neighbors of this registrar correspondence and IP address.As the node in lower floor's sub-network, each registrar has a neighbor node table TN of lower floor, this list records in lower floor's sub-network, the mapping of the logical address of its neighbors and IP address.
The maintenance of information server node relationships: as the node in lower floor's sub-network, for each logical address Ad, each information server I has a neighbor node table TN of lower floor (Ad), this list records in lower floor's sub-network, according to logical address Ad, the mapping of the logical address of the neighbors of this information server correspondence and IP address.Information server I has the logical address of certain registrar in this sub-network and the mapping of IP address simultaneously.
The dynamic management of node in this network: this hierarchical network need possess good extensibility, therefore need carry out dynamic management to the node in the network, add Network Management and information server adding and the management that exits network comprising registrar.
Registrar adds Network Management: the quantity of registrar can dynamically increase according to the storage demand of log-on message.When registrar R1 request adds hierarchical network, carry out following operation:
A, certain the registrar R2 with a plurality of upper layer logic address and registrar R1 consult, and give new registrar R1 with part upper layer logic address assignment;
B, registrar R2 will be corresponding to the Item Information unloading of these upper layer logic addresses to registrar R1 (information stores of article be on the node of fixed logic address);
C, registrar R1 add lower floor's sub-network at registrar R2 place and by each node in the information broadcast notice sub-network;
Registrar in d, the upper layer network upgrades the neighbor node table of each registrar by message.
Information server adds with the management that exits network and comprises the management that information server adding Network Management and information server exit network:
Information server adds the management of certain lower floor's sub-network: when information server I1 request adds certain lower floor sub-network, carry out following operation: information server I2 and information server I1 with a plurality of lower floors logical address consult, and part lower floor logical address is distributed to information server I1; Information server I2 will be corresponding to the Item Information unloading of these lower floor's logical addresses to information server I1; Information server in lower floor's sub-network upgrades the neighbor node table of each information server by message.
Information server withdraws from the management of certain lower floor's sub-network: the information server in lower floor's sub-network is safeguarded the survival condition information of neighbors by message, if information server I3 finds that certain information server I4 exits network, then I3 broadcast node I4 in lower floor's sub-network withdraws from the message of lower floor's sub-network, and the information server in lower floor's sub-network heavily distributes the logical address of this information server by exchanging messages.
The Internet of Things multidate information storage system extensibility of stratification of the present invention is strong, show that not only registrar in kind can dynamically add upper layer network to adapt to increasing of storage demand, the information server in kind that further shows as lower floor can independently select to add or withdraw from lower floor's sub-network flexibly.
