Description
Technical field
The present invention relates to network transmission technology, relate in particular to terminal identifier parsing and the professional method, system and device that transmit in a kind of integrated network.
Background technology
Integrated network is the Typical Representative in the next generation network (NGN), and it can merge the advantage of existing diverse network, the transmission of the multiple different business of good support.The various network service business that provided by operator or third party value-added service provider are provided in the integrated network, and various service business adopt unique service identifiers to identify, and the terminal in the integrated network also adopts unique terminal iidentification to identify simultaneously.
In legacy network, mainly be to realize the corresponding of IP address and domain name by domain name system (DNS), DHCP (DHCP) or dynamic territory analyzing system (DDNS), namely realize IP address-based parsing.
The DNS technology is a distributed data base, and it allows the various piece of whole database is carried out this locality control.Simultaneously, whole network also can be accessed by the client-server mode data of each part.
DHCP is by internet engineering task group (IETF) design, and purpose is exactly for the planning that alleviates transfer control protocol/Internet protocol (TCP/IP) network, the burden that administers and maintains, and solves IP address space and lacks problem.The operation mechanism of DHCP technology is roughly as follows at present: use the server of DHCP to concentrate the terminal of backward request access dynamically to carry out the distribution of IP address the network settings of TCP/IP, basically do not need network management personnel's human intervention.And DHCP is the expansion of Bootstrap Protocol (BOOTP), need can support the non-disk workstation of network configuration message, and needs the fixedly system of IP.
DDNS generally is made of two parts, and first is positioned at dns server, and another part is Dynamic Host Configuration Protocol server.In each SCN subscriber connection network, Dynamic Host Configuration Protocol server will be distributed to dynamic IP addressing by the message transmission main frame of operation DHCP source terminal program, be terminal A, Dynamic Host Configuration Protocol server obtains the domain name of terminal A by message interaction simultaneously, then Dynamic Host Configuration Protocol server will send dns server to for the dynamic IP addressing that terminal A distributes, dns server is new data more immediately, with new IP address and the binding of terminal A domain name, so just finished the service of dynamic territory analyzing, other main frames can pass through domain name access terminal A.
Owing to not being to use the IP address as terminal iidentification in integrated network, so can't realize terminal identifier parsing in the integrated network by said method.Simultaneously, traditional technology such as DNS can't the indication network service, the corresponding relation between Internet resources and the host identities sign, therefore utilizes these existing technology also can't realize the corresponding of terminal iidentification and service identifiers in the integrated network.
Existing method about domain name mapping and resource lookup except the above-mentioned central server method such as the DNS method, also have Peer between each main frame without center infrastructure lookup method, such as point-to-point (P2P) method.
The P2P mode is the distributed network system (DNS) that does not have center-control and hierarchy, it is made of the node of several interconnected cooperations, each node is played the part of the role of server and source terminal simultaneously, the identical resource lookup algorithm of operation finds the node that has accordingly specific resources between them by certain search rule.As shown in Figure 1, take compatible hashing algorithm as example, the process of domain name mapping and resource lookup is described.This algorithm has proposed a kind of fast distributed computational methods of hash function, more given keywords, keyword is mapped in the system reliably on the node, guarantees that by the method for using compatible hash function all nodes can both receive the essentially identical keyword of quantity.Each node in the network only need to be known the resource information of other a small amount of nodes, and when searching, node will be inquired about its descendant node successively, until find keyword or travel through complete network.For example when node N8 needs key word of the inquiry to be the resource record of k54, it at first according to the resource record table that stores itself, find that node N42 has in its resource record the keyword near keyword k54, then inquire node N42, see whether N42 knows which node is more near keyword k54, by repeating this process, node N8 can know that finally keyword is the memory location of the resource record of k54.Search procedure as shown in Figure 2.
The P2P method can be applied in the legacy network and also can be applied in the integrated network, do not need the support of center infrastructure services device, but, because the P2P mode does not have central server to be responsible for unified management and the authentication of these resource records, so that the authority of resource record can't be protected, if there is malicious behaviors of nodes to claim oneself storage or support the service of certain keyword then other nodes can't be verified it to network; The simultaneously fail safe of network can't be guaranteed, if certain node is by malicious attack then the parsing of this node can't be provided and search service in the network; The distributed resource storage format of this equity is unfavorable for management, and when having new node to enter or to have node to withdraw from, all the other nodes are difficult to obtain at short notice the modification that message carries out the resource record table; The P2P method can't realize parsing and the resource lookup based on terminal iidentification in integrated network in addition.

In embodiments of the present invention, the terminal of initiating request message is called source terminal, can provides the terminal of the service of described source terminal request to be called the purpose terminal.
The terminal identifier parsing method is applied to comprise in the system of identification server and at least two terminals in the integrated network in the embodiment of the invention, the request message that sends of reception sources terminal at first, the service identifiers that comprises described source terminal request in this request message, then from the corresponding relation of the sign of the terminal of pre-save and the service identifiers that this terminal is supported, find out the corresponding purpose terminal iidentification of service identifiers of described source terminal request, and returning the answer message to described source terminal, described answer message comprises described purpose terminal iidentification.The below is described in further detail method in the embodiment of the invention.
The resolving of terminal iidentification as shown in Figure 4, was steps flow chart schematic diagram in the embodiment of the invention 1 when embodiment 1 integrated network internal source terminal was initiated service request, and the method may further comprise the steps:
Step 401: purpose terminal iidentification assigning process, this process may further comprise the steps:
Steps A 1: the described inside sources terminal that expansion DHCP agreement is installed sends request (Request) message to the identification server that expansion DHCP agreement is installed equally, service identifiers that source terminal sign, this source terminal support and the service identifiers of request have been comprised in this Request message, because this source terminal is integrated network inside, distributed in advance terminal iidentification, so need to do not reallocated by identification server.
Steps A 2: after identification server receives the Request message, whether inquiry preserves the purpose terminal that the service of asking in this Request message can be provided in the corresponding relation of the service identifiers that the terminal iidentification from the system that comprises an above terminal of pre-save and this terminal are supported, i.e. whether inquiry preserves the corresponding purpose terminal iidentification of service identifiers of described source terminal request.If preserve, then this identification server sends a reply (Reply) message to source terminal, comprise the service identifiers of request and the corresponding purpose terminal iidentification of service identifiers of one or more requests in this Reply message, inform that namely source terminal can provide to it purpose terminal iidentification of the service of request; If do not preserve, then this identification server still sends the Reply message to source terminal, comprises failure (UnspecFail) information in status code fields, informs the purpose terminal that source terminal does not exist can provide to it service of request.
As shown in Figure 5, Request message format schematic diagram for the DHCP agreement of expansion in the embodiment of the invention 1, wherein, option code field has defined the title of source terminal main frame, the option value can be 128, the length of terminal iidentification is 128 unique long character strings, terminal iidentification has defined the sign of source terminal, service identifiers has defined the sign of the service that source terminal supports, the request service sign has defined the sign of the service of source terminal request, use for convenient, the service identifiers that this source terminal can be supported and the service identifiers of request are during less than 128, and unnecessary figure place can be by 0 filling.
As shown in Figure 6, Reply message format schematic diagram for the DHCP agreement of expansion in the embodiment of the invention 1, wherein, option code field has defined the title of identification server, option is the length of identification server title, status code fields has defined the state of present message, for example, when if identification server inquires the corresponding relation of the service identifiers of the request of having preserved and purpose terminal iidentification, this status code fields is successful (success) information, if when preserving the corresponding relation of the service identifiers of request and purpose terminal iidentification, this status code fields is UnspecFail information, terminal iidentification has defined the terminal iidentification of identification server, and service identifiers has defined the service identifiers of the source terminal request that identification server preserves, and the purpose terminal iidentification defined the terminal of the service identifiers of supporting this request.
Step 402: whether the mutual negotiation of identification server and source terminal carries out the identification renewal process, and this process may further comprise the steps:
Steps A 3: after source terminal receives the Reply message, confirm the information in this Reply message.For example, the service identifiers that in the Reply message, also comprises request, and when the service identifiers of the request in should service identifiers and the Request message of request is identical, then source terminal is confirmed the information in the Reply message, relevant option information in the Reply message is represented to accept, send an identification renewal (ID_UPDATE) message to identification server, carry out identification renewal, this ID_UPDATE message comprises the corresponding relation of the service identifiers that source terminal sign and this source terminal are supported at least.If source terminal is not accepted the relevant option information in the Reply message of receiving, in the inconsistent situation of service identifiers such as the service identifiers of the request in the Reply message and the request in the Request message, then send a Reply message to identification server, wherein the content of option with receive consistent, but status code fields changes UnspecFail into, stops renewal process this moment.
Steps A 4: receive the ID_UPDATE message of source terminal transmission when identification server after, then check internal record, judge whether to preserve the corresponding relation of the service identifiers that source terminal sign and this source terminal support, judge whether that namely the terminal iidentification that has had other terminal to use the source terminal of described initiation Request message has carried out the renewal with the service identifiers corresponding relation.If do not have, then check and pass through, if have, when but this service identifiers is not identical with the service identifiers of supporting described in the steps A 1, also explanation checks and to pass through, and again sends the Reply message to source terminal, and is the same in its content and the steps A 2, this moment, identification server and source terminal both sides consulted successfully, then the corresponding relation preservation of identification server service identifiers that this source terminal sign and this terminal are supported.If find to have had the terminal iidentification of the source terminal of described initiation Request message to carry out renewal with the service identifiers corresponding relation, and when this service identifiers is identical with the service identifiers of supporting described in the steps A 1, then check and do not pass through, send Reply and proof (Authentication) message to source terminal, wherein, consistent in the option content of Reply message and the steps A 2, but the status code fields content changes UnspecFail into, the source terminal of Authentication message requirement initiation Request message provides the relevant authentication information about this terminal iidentification, at this moment, source terminal can be selected the renewal that stops to identify or the terminal iidentification of changing the source terminal main frame to enter step 1 and resend the Request message.
Step 403: identification server is mutual with the sign authentication server, carries out identification renewal.This process comprises following steps:
Steps A 5: identification server requires the sign authentication server to carry out identification renewal to ID_UPDATE message described in the sign authentication server forwarding step A3.
Steps A 6: after the sign authentication server is received the message that identification server sends, judged whether to preserve the record of the corresponding relation of the service identifiers that source terminal sign and this source terminal support.If do not exist, or exist when still this service identifiers is not identical with the service identifiers of supporting described in the steps A 1, then the terminal iidentification of this source terminal and the corresponding relation of the service identifiers of supporting are preserved, become new record, simultaneously, set the life span of this record, when life span arrives, the sign authentication server will be deleted this corresponding relation of preserving.Because source terminal can be changed the service content of supporting at any time, so if do not set life span, after the service content that the source terminal change is supported, the data of preservation are not but upgraded, and are unfavorable for maintenance and management.After being updated successfully, the sign authentication server sends the Reply message to identification server, initiate the source terminal of Request message and the transfer of data of purpose terminal realization in integrated network of the service that can support this request this moment, and the service corresponding relation of this source terminal and its support is kept at identification server and sign authentication server, when the source terminal that other are arranged was initiated the Request message again, this source terminal also can be used as a purpose terminal and participates in transfer of data in the integrated network.
If find to have existed the terminal iidentification of an identical source terminal to carry out record with the renewal of service identifiers corresponding relation, and when this service identifiers is identical with the service identifiers of supporting described in the steps A 1, the sign authentication server then sends Reply and Authentication message to identification server, the status code fields of this Reply message is UnspecFail, identification server again with these two message repeatings to source terminal, stop to upgrade this moment.
As shown in Figure 7, ID_UPDATE message format schematic diagram for the DHCP agreement of the expansion in the embodiment of the invention 1, terminal iidentification has defined the terminal iidentification of source terminal main frame, service identifiers has defined the service identifiers that this source terminal is supported, the type that type field has defined message is the UPDATE message, class definition the class of message be sign class message, sign length has defined the length of service identifiers, life span has defined the life span of corresponding relation in the sign authentication server of the service identifiers that this source terminal sign and this terminal support, in the present embodiment, can set the life span of giving tacit consent to identification server transmission ID_UPDATE message when source terminal is 24 hours, the sign authentication server can be changed this acquiescence life span, the request service sign has defined the service identifiers of this source terminal request, and the purpose terminal iidentification has defined the terminal of the service identifiers of supporting this request.
After 403, finished the process of terminal identifier parsing in the integrated network by step 401, on this basis, source terminal can be according to the connection between the purpose terminal iidentification foundation that the obtains purpose terminal corresponding with this sign, and carry out the multiple business transmission, such as carrying out transfer of data, audio service transmission or video traffic transmission etc.The below illustrates business transmitting method in the integrated network as an example of data transmission procedure example.
In the situation that comprise above-mentioned steps 401 to 403, business transmitting method also comprises the connection between the source terminal foundation purpose terminal corresponding with described purpose terminal iidentification in this integrated network, and the industry of going forward side by side is engaged in transmitting this step.
Source terminal connects according to purpose terminal identification information and this purpose terminal that identification server returns, and namely source terminal is set up corresponding relation with the link address sign of self terminal iidentification and one or more purpose terminals.Then the link address sign is mapped to the routing address sign again.In addition, if source terminal is to link integrated network by integrated access switch router, need to use the access address sign, and be converted into the routing address sign by integrated access switch router, the routing address sign is used in the integrated network routing.At last, according to the reasonable routing that obtains, transferring service data between the server at source terminal and purpose terminal place is finished the once complete business transmission under the integrated network.
The be moved resolving of terminal iidentification when entering integrated network of the source terminal of embodiment 2 integrated network-external, as shown in Figure 8, be model structure figure in the embodiment of the invention 2, mainly contained by source terminal, identification server, identification mark server and several that the terminal of terminal iidentification forms in integrated network.As shown in Figure 9, be steps flow chart schematic diagram in the embodiment of the invention 2, the method may further comprise the steps:
Step 901: purpose terminal iidentification assigning process, this process may further comprise the steps:
Step B1: the unappropriated terminal iidentification that the sign authentication server will identify in the pond sends to identification server.
Step B2: by the interaction mechanism of source terminal and identification server, the identification server that the source terminal main frame that name is called iplab.njtu.edu.cn is called ngirc.njtu.edu.cn to name is sent in the Request message of the procotol that outer net uses, for example, if this source terminal is that this Request message format was the IP message format when source terminal accessed integrated network in the internet.Not only comprise service identifiers that this source terminal supports and the service identifiers of request in this Request message, also comprised the previous address of distributing on this source terminal.
Step B3: the Request message that identification server sends source terminal according to previous address information changes the Request message format that adapts to expansion DHCP agreement in the integrated network into, and whether inquiry preserves the purpose terminal iidentification of the service that the request that comprises in this Request message can be provided, if have, then this identification server sends the Reply message to this source terminal, comprises the terminal iidentification of identification server itself, service identifiers and one or more purpose terminal iidentification of request in this Reply message.This Reply message format as shown in figure 10, the name of the identification server of option code field definition is called ngirc.edu.cn, option code length is 10, status code fields is defined as success, the identification server terminal iidentification is Dfhw125467990jk1237hjelhjkd, the service identifiers of request is 110000000000000000000000000, and the purpose terminal iidentification is respectively bndkjk46578793783937hsdjf10, bndkjk46578793783937hsdjf11 and bndkjk46578793783937hsdf12.If do not preserve, then this identification server still sends the Reply message to this source terminal, comprises failure (UnspecFail) information in status code fields, informs the purpose terminal that source terminal does not exist can provide to it service of request.
Step B4: after source terminal main frame iplab.edu.cn receives this Reply message, again send the Request message to identification server ngirc.njtu.edu.cn, require to distribute for it the terminal iidentification in the integrated network.
Step B5: after identification server receives the Request message that source terminal sends for the second time, again send the Reply message to source terminal, comprise the terminal iidentification of distributing to this source terminal in this message, this terminal iidentification that is assigned with is distributed in the unappropriated terminal iidentification of identification server by sign authentication server among the step B1 and is produced.
