Embodiment
As a kind of new Internet architecture system, the characteristics that ID/Locator (identify label/station location marker) separates are that main frame has two types of signs simultaneously: identify label and station location marker.Identify label remains unchanged in main frame moves towards upper layer application, supports the writing to each other property of using; Station location marker is transmitted and route towards the bag of lower floor, changes with moving of main frame; Between identify label and the station location marker,, set up corresponding relation through mapped system/service dynamic, that support real-time update.Such as host identity protocol is wherein comparatively typical and perfect one.
As shown in Figure 1; Host identity protocol is between network layer and transport layer; Introduced new protocol layer and based on the NameSpace of asymmetric cryptosystem, a host identity layer HIP has been introduced in the binding of having broken identity sign and topology location between transport layer and network layer.In host identity protocol, the station location marker that the IP address only is used as in the network uses, so HIP isolates transport layer and IP interconnection layer.The IP agreement of bottom is indifferent in transmission itself, and the interface that transport layer provides to application layer mainly comprises identity ID (identify label) and protocol port.The HIP layer is mainly accomplished the conversion process of host identification to the IP address; Therefore; HIP needs the mapping relations of maintenance host sign with the IP address, and this relation mainly comprises the mapping relations of opposite end host identification and IP address and the mapping relations of local terminal host identification and IP address.
Equipment in the network has identify label, station location marker and host name simultaneously; And there is corresponding relationship between the three; Promptly; Can search corresponding station location marker and/or host name according to identify label, also can search corresponding identify label and/or host name according to station location marker.
Because communication is begun by identify label, upper layer application is not paid close attention to the station location marker of the concrete network equipment, but route but is based on station location marker; That is to say, must find corresponding station location marker, and carry out route according to station location marker according to the identify label of the network equipment; Make the conversation between both sides to set up; So, be necessary between identify label, station location marker and host name, to found certain corresponding relation, searching and retrieving according to what this corresponding relation was correlated with.
When searching and retrieving according to corresponding relation; For more convenient, search faster; Can also in the corresponding relation between identify label, station location marker and the host name, set up sub-corresponding relation; Such as: there is corresponding relation between some field in the identify label and some field in the station location marker, just can finds according to this corresponding relation and specifically go which database or server to search; Perhaps; Some field in the identify label is (such as utilizing specific algorithm through certain rule; Import the data that certain rule produces) form; And can generate station location marker equally through this rule, so, also can find through this rule and specifically to go which database or server to go to search.
In addition, can also identify label, station location marker and host name be carried out correspondingly simply one by one, no matter whether identify label is flattening.Server can be set, store the correspondence database of identify label, station location marker and/or host name in the server, as shown in table 1.
| Identify label | Facility information | |
| HIA | Station location marker A | Host name A |
| HIB | Station location marker B | Host name B |
| HIC | Station location marker C | Host name C |
Table 1
In this server,, just can directly find other corresponding informances through importing any one in identify label, station location marker and the host name.Such server can have only one, also can have many, is separately positioned in interior, the different area of various network, safeguards simultaneously.If there are a plurality of servers, then can active and standby pattern between the server, also can be synchronous mode.Can a mapping server job; Other mapping server if the work mapping server breaks down, is then perhaps specified wherein conduct work mapping server according to certain strategy election as backup in remaining mapping server; Perhaps; Several mapping servers can be worked simultaneously, one break down after, as long as also exist can operate as normal mapping server.
Such as shown in Figure 2; It is the request (201) of the corresponding station location marker of HIT B that network equipment HostA sends an inquiry identify label to server S erver, after server S erver receives this request, inquires about its database; Find corresponding data with HIT B; And the corresponding station location marker B of HIT B sent to HostA (202), HostA just can directly use the information in this station location marker to carry out route, converses with Host B.
Simultaneously; Can introduce Management Domain (MD, management domain), contain the field of same section in the identify label of the network equipment in the MD; With the sign MDID of the same section that all contains in the identify label as the MD territory; Such as shown in Figure 3, all have the field of 1F00 in the network equipment identify label in this MD, then can be with 1F00 as this MD domain identifier (management domain sign).Certainly, this identical part is not confined to the beginning that identifies, can be in middle, end, perhaps optional position yet.
One or more server (special server is perhaps by the Daepori open network equipment double as server in the territory) can be set as mapping server in MD; Server stores has the station location marker of all devices in this MD territory and the corresponding relation of identify label and/or host name; And; In server, also store the corresponding relation of different management domains sign and corresponding server address, when server according to received query requests, when finding that management domain that equipment to be checked belongs to is other territories; Just can query requests be gone to corresponding server; Inquire about accordingly by this server, perhaps, server info is transmitted to the network equipment of filing a request.
If there are a plurality of servers, then can active and standby pattern between the server, also can be synchronous mode.Can a mapping server job; Other mapping server if the work mapping server breaks down, is then perhaps specified wherein conduct work mapping server according to certain strategy election as backup in remaining mapping server; Perhaps; Several mapping servers can be worked simultaneously, one break down after, as long as also exist can operate as normal mapping server.
As shown in table 2; Preserve the information of different management domain signs (MDID) and its corresponding mapping server (LMS) in the mapping server; Each management domain sign can form corresponding with the information of a mapping server, also can form corresponding with the information of a plurality of mapping servers; Equally, a plurality of management domains sign also can a shared mapping server, forms the corresponding relation with a mapping server information.
| The management domain sign | Mapping server (LMS) information |
| MDID?a | |
| MDID?d | LMS 3 station location markers |
| MDID?d | LMS 4 station location markers |
Table 2
As shown in table 3; In mapping server; Also preserve the identify label of all-network equipment in its pairing management domain and the map information of station location marker or host name; Through inquiring about this map information, can use identify label directly to find the station location marker or the host name of its corresponding network equipment.Table 1 is that with table 3 difference part what table 3 was stored only is the information with network equipment of same administrative domain sign, perhaps, the information of the network equipment of other management domains of part can also be arranged.
| Identify label | Facility information | |
| HI?AA | Station location marker AA | Host name AA |
| HI?AB | Station location marker AB | Host name AB |
| HI?AC | Station location marker AC | Host name AC |
Table 3
When network equipment Host1 searches retrieval at needs, can select:
1, searches services request through the default position sign of local mapping server to one of local mapping server LMS1 proposition; Perhaps
2, search services request through the station location marker of local mapping server to one of local mapping server LMS1 proposition,
Search and to show clearly in the services request that what search is station location marker or host name; Can also ask to search station location marker and host name simultaneously, certainly, as required; The acquiescence mode can also be set; That is, proposing that this request just is defaulted as is request station location marker and host name, and other acquiescence modes perhaps are set.
If preserve this identify label in the local mapping server LMS1, then in identify label that is similar to table 3 or table 1 and facility information correspondence table, search, according to request, the result who finds is sent to requesting party Host1; If do not preserve this identify label in the discovery server,, find the mapping server LMS2 of correspondence in the management domain sign of removing to be similar to table 2 and the mapping server information correspondence table, then then according to the management domain sign of waiting to look in the identify label
1, by local mapping server LMS1 this is searched services request and be transmitted to the mapping server LMS2 that is found; LMS2 searches by this mapping server; And lookup result directly sent to the network equipment Host1 of request; After perhaps sending to local mapping server LMS1, be transmitted to requesting party Host1 again by local mapping server LMS1; Perhaps
2, by local mapping server LMS1 the information of the mapping server LMS2 that finds is sent to requesting party Host1; Requesting party Host1 is after LMS2 sends request; Search by this mapping server LMS2 again, and lookup result is directly sent to the network equipment Host1 of request.
It is understandable that, can preserve the identify label of all-network equipment in the MD territory at its place in the local mapping server LMS1, and the corresponding relation of identify label and out of Memory; Also can further preserve the identify label of some network equipments in other territories, and the corresponding relation of identify label and out of Memory.
It is understandable that; After local mapping server LMS1 receives query requests; Can be of above-mentioned embodiment; Go earlier to search and have or not and corresponding station location marker of this identify label and/or host name,, then search and the corresponding mapping server of this identify label according to the sign of the management domain in the identify label if do not have; Also can be after local mapping server LMS1 receives query requests; Resolve the identify label to be looked in the query requests earlier,, then can directly search and the corresponding mapping server of this identify label according to the sign of the management domain in the identify label if the sign of the management domain in this identify label is different with the management domain sign of the management domain at local mapping server LMS1 place.
Certainly, if mapping server is searched less than corresponding results, then can select to send an error message to the requesting party:
If 1 does not find in identify label and facility information correspondence table, and the management domain sign in the identify label is identical with the management domain sign of the MD at mapping server place, then can send an error message that does not find to the requesting party; Perhaps
If the sign of the management domain in 2 identify labels is different with the management domain sign of the MD at mapping server place; But in identify label and facility information correspondence table, management domain sign and mapping server information correspondence table, all do not find; Then can send a wrong error message of MD sign to the requesting party; Represent that the MD sign in the identify label of this request can not discern, perhaps, belong to mistake MD sign.
In management domain as shown in Figure 4, when certain communication equipment H wants to inquire about identify label and is HIT W, can in this MD territory, submit a search request that comprise known identities sign HIT W to; Search the pairing host name of this identify label; Such as, communication equipment H sends this search request (401) to default position sign x, then according to this default position sign x; Router or other relevant equipment can be according to this default position signs; Selection sends to search request from the nearest mapping server of communication equipment H route, perhaps, selects to send to simultaneously all mapping servers.
When search request only sends to from the nearest mapping server of communication equipment H route; Because mapping server A1 distance communication equipment H route is nearer; So mapping server A1 can reply this request; If mapping server is through resolving; Find that the pairing management domain sign of this identify label belongs to this management domain, then mapping server A1 directly searches the pairing host name of this identify label in the database of its storage, and this host name Host W is sent to the communication equipment H (402) that files a request.
When search request sent to all mapping servers simultaneously, mapping server A1 and A2 can resolve accordingly, search.
More than be to send request,, also can select directly to file a request, reply by corresponding mapping server to mapping server A1 or A2 if communication equipment H knows the station location marker of mapping server A1 or mapping server A2 through the default position sign.
As shown in Figure 5; If the management domain of MDa, MDb and MDc sign is respectively 1F01,1F02,1F03; Then can select these management domain identification informations are carried out polymerization; Set up a superserver, perhaps specify one of them server, externally only send the map information of 1F0/24 position as Relay Server.
In this case, after the management domain polymerization, can map information be circulated a notice of to each mapping server, mapping server also upgrades accordingly.As shown in Figure 6; After certain communication equipment HA submitted request (601) to, the mapping server LMS A in this management domain was designated 1F01 through searching if find the management domain among this identify label HIT E; Drop within the 1F0/24; The server LMS B (602) that then can this request is forwarded in the database to be shown, perhaps the station location marker with this server sends to H A (603), inquires about (604) by H A to LMS B.
Server LMS B is after receiving inquiry; If this server LMS B belongs to superserver, that is, store the communication device position sign that all management domains are designated 1F0/24 in this server; Then can directly in database, inquire about, and Query Result is sent to LMS A or H A; If this server belongs to Relay Server, then can this request be transmitted to sign pairing mapping server LMS C (605), inquire about in database by LMS C.
In addition; As shown in Figure 7, in actual networking, can also introduce the notion of territory, network site LD; The field that all contains same section in the station location marker of each network equipment in LD; With the sign LDID (position field sign label) of the same section that all contains in the station location marker as the LD territory, a LD possibly be a management domain MD, also possibly form a MD by a plurality of LD.It is understandable that in the network architecture, LD belongs to different layers respectively with MD, wherein LD belongs to independent network layer, and MD then belongs to host identification HIP layer.
One or more server (special server is perhaps by the Daepori open network equipment double as server in the territory) can be set as mapping server in MD; And one or more server can be arranged in the LD as mapping server; If a plurality of LD form a MD, then a plurality of LD can shared one or more server.
Like this; Position field sign label LDID in the station location marker can represent the LD that this equipment belongs to, like this; Preserving all in the mapping server, management domain identifies in the information of (MDID) and its corresponding mapping server (LMS); The station location marker of mapping server can represent with its actual station location marker, also can represent with the form that its location position field sign label LDID adds default virtual map server location sign (below be called " default position sign "), and is as shown in table 4:
| The management domain sign | Mapping server (LMS) information |
| MDIDx | LDIDx+ default position sign |
| MDIDy | The station location marker of LMSy |
Table 4
According to default position sign, the network equipment can be directly with this MD in mapping server communicate, just, this default position identifies the directly concrete mapping server of sensing.
And if management domain sign and position field sign label have corresponding relation; This corresponding relation can be for being equal to (being that the management domain sign is position field sign label equally) or shining upon according to particular kind of relationship; Then when the network equipment need be searched retrieval; The management domain identification division of the identify label of searching as required forms the station location marker that searching object belongs to the management domain mapping server, utilizes this station location marker directly to initiate query requests to the management domain mapping server at searching object place.
Like Fig. 8, main frame Host X is if the management domain of the identify label HIT Y of searched network apparatus sign and Host X identical also is 1F01, then to the local mapping server A1 initiation query requests (801) of Host X place management domain; If the management domain of the identify label HIT Z that searches is designated 24A1; Then obtain the position field sign label of management domain B earlier through ad hoc approach; Directly initiate query requests to the network at this LD place then; Point to a total virtual map server location sign (802), correspondingly handle this search request by the default map server B 1 of this network.
Such as, be the same, then can directly use the form of " management domain sign+default position sign " to send request if the management domain sign identifies between the label with position field to corresponding mapping server; If have particular kind of relationship between management domain sign and the position field sign label; Such as, position field sign label is " management domain sign+other specific fields ", perhaps other specific forms; Then can management domain sign be transformed into after the position field sign label; Re-use the station location marker after the conversion,, send request to corresponding mapping server such as " management domain sign+other specific fields+default position sign ".In this case, just can preserve the corresponding relation of different management domain signs and corresponding server address in the mapping server.Can find out; In embodiments of the present invention; Through such lookup method, can find and corresponding station location marker of network equipment identify label and/or host name through the corresponding relation between identify label, station location marker and the host name three very easily.
