Description

The processing method of client/server application and centralized processing system

Technical field

The present invention relates to the communications field, in particular to a kind of processing method and centralized processing system of client/server application.

Background technology

In at present typical IP network is disposed and is used, use for realizing the convenient of network, generally all be deployed with DHCP (Dynamic Host Configuration Protocol; DHCP) server and DNS (Domain Name System; Domain name system) server is realized the automatic distribution of IP address respectively, and the parsing of domain name; Carry out complicated configuration thereby save the user, perhaps remember the network address that some are difficult for memory.Generally speaking, in each network, all need carry out such deployment, just difference to some extent on scale.For example in the INTERNET network, a plurality of DNS root servers being arranged, is that very important network function is disposed, and need take the high reliability measure, to guarantee the high availability of network.And in small business's network, then can be a PC server, realize the function of relevant address assignment and parsing.Certainly, possibly be hierarchical setting to dns resolution, do not do further consideration here.At user network is under the situation of being planned, disposing and being managed by Subscriber Unit oneself, these functions, and the network manager by the user accomplishes separately fully.According to the demand of function, and the demand of performance, different device levels and corresponding reliability measure can be adopted.

Fig. 1 is typical DHCP and dns server application deployment sketch map in network.In each network (enterprise network among the figure), because the consideration of use and convenient management all will be deployed with DHCP and dns server.Subscriber computer/PC (generally need in operating system, do some settings) is after powering up; At first need obtain the IP address automatically; This generally is to realize through DHCP; Resolve the IP address of needed URL (Uniform Resource Locator, URL)/domain name then through dns server, realize communication through the IP message.Because the IP address assignment scheme in each network is different; And the server in the different enterprise networks; Possibly take different addressing/nomenclature scheme, so DHCP and dns server, different databases is arranged; Though its processing capacity is the same, promptly can realize through using identical software systems.

But; Under a kind of new applicable cases, particularly under the background that cloud computing is progressively popularized, user's network is that the business through operator provides and realizes; Be that the enterprise customer no longer needs enterprise customer oneself to go to buy, dispose and manage the relevant network facilities; And carry out relevant network application function and dispose, and, obtain relevant network and some basic network application functions directly from the service provider there.And see from the angle of operator; Outside the basic network that user network is provided connects, also need be respectively each user network (customer network) independently DHCP and DNS function are provided, because each user's IP address planning; And the planning of the domain name of some built-in systems is very different; Unlikely realize, and further also have the demand of network security aspect, need isolate network through a cover system.

Like this, one obvious, also is that feasible solution is really, is respectively each user network independently DHCP and dns server are provided, and realizes function associated, the same in the time of just with client oneself realization network.

But this implementation has its irrational place.For example, under the situation of network design practice at present, need a large amount of PC/ servers to realize function associated; Therefore unreasonable on the matching of function; It is required that disposal ability far surpasses reality often, causes certain wasting of resources, in addition; Need the so many server/computer/PC of management, management cost also can be than higher.

Embodiment

Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.

Embodiment one

Fig. 3 is the process chart according to the C/S application of the embodiment of the invention one, and is as shown in Figure 3, may further comprise the steps:

The C/S that step S302, centralized processing system receive from different customer networks uses message.

Step S304, centralized processing system is used message to the C/S that is received and is handled.

Step S306, centralized processing system is back to the corresponding client network with result.

In the present embodiment, use, solved the problem of the C/S application server wasting of resources, and then reached the effect that reduces management cost, improves the efficiency of management through the C/S that focuses on from each customer network.

Wherein, customer network can be enterprise network, perhaps need carry out the network of said C/S application processes, perhaps subnet (back together).Professional relaying or agency are set, for example DHCP relay or agency in enterprise network; Centralized processing system is positioned at external network, specifies through using a public IP address.Service agent sends to centralized processing system with the message unification that relevant C/S uses.And other number of C/S is used, for example DNS can directly handle through the IP network of bottom, and does not need special agency or trunking mechanism, when promptly having IP network to connect in customer network with between focusing on, promptly can realize relevant processing.

Wherein, professional relaying in the enterprise network or agency use the network identification information that message carries relevant enterprise network at the C/S that is sent.Centralized processing system combines the outlet IP address of enterprise network, and relevant attribute classification, DHCP Option82 for example, and perhaps the port numbers of agreement etc. can be distinguished various network, to realize different processing.

Wherein, centralized processing system can be one, perhaps many/one group PC or PC server, and perhaps blade server, or custom-designed computer system can be formed group system or distributed system.Centralized processing system can realize that a plurality of C/S handle instance, realizes the processing and the management work of the C/S application of relative clients network respectively, guarantees the high availability of system simultaneously.

Embodiment two

Fig. 4 A is that shown in Fig. 4 A, this network configuration comprises enterprise network 1 and enterprise network 2 according to the network structure of the C/S application of the embodiment of the invention two, and enterprise network 1 can insert the ISP/INTERNET network with enterprise network 2.Wherein, In enterprise network 1 and enterprise network 2, being respectively arranged with a DHCP relay or agency (uses DNS, because the difference of realization mechanism does not need for the proxy settings; And it is directly machine-processed through the IP network of bottom; Realize the direct forwarding of message), DHCP proxy is connected to a centralized processing system, and this centralized processing system comprises Dynamic Host Configuration Protocol server and dns server.

Wherein, Dynamic Host Configuration Protocol server and dns server can be one, perhaps multiple pc machine or PC server, and perhaps blade server, or custom-designed computer system can be formed group system or distributed system., this need decide according to the size in disposal ability and relevant data storehouse.

In the present embodiment, through distributing the public IP address to realize focusing on of DHCP to the processing server in the centralized processing system.

Because PC before obtaining the IP address, need send DHCP and find (broadcasting) message, DHCP handling process of the prior art is shown in the step S202 to 210 of Fig. 2: Dynamic Host Configuration Protocol server; Receive that this DHCP finds message; And handle and return a DHCP information is provided, PC provides information according to a plurality of DHCP that possibly return, and selects one of them to send dhcp request message; From this Dynamic Host Configuration Protocol server, obtain the IP address.Because this handles flow process is prior art, do not do detailed explanation at this.

Generally speaking, DHCP and DNS do not need too many disposal ability in small-/medium-sized Intranet, that is to say, with the disposal ability of present PC, possibly satisfy the DHCP of a plurality of networks and the processing requirements of DNS fully.And the consideration of reliability aspect, because can be through disposing a plurality of Dynamic Host Configuration Protocol server, and relevant mechanism such as active and standby dns server realizes.But because the configuration of each network is different, owing to the consideration of secure context, this disposal ability must be isolated, and cannot influence each other in addition.Therefore, share under the situation about realizing, just can focus on, and must realize the isolation of safety at network.A kind of implementation is that the public IP address through operator disposes the realization Dynamic Host Configuration Protocol server.Like this, just can solve relevant Network Isolation problem.

Because Dynamic Host Configuration Protocol server is not arranged in enterprise network, DHCP application message need send in the external network and go, and therefore in the process that focuses on, relevant requirements of process makes a change.Fig. 4 B is according to the DHCP process chart of the C/S application of the embodiment of the invention two, shown in Fig. 4 B, may further comprise the steps:

Step S402, inner at enterprise network, dispose relevant DHCP relay or agency, collect relevant DHCP by DHCP relay or agency and find message.

Step S404, DHCP relay or agency find that with DHCP message is forwarded to the Dynamic Host Configuration Protocol server of external network.Wherein, DHCP relay or agency find to carry relevant attribute classification in the message at the DHCP that is sent, for example DHCP Option82.

Wherein, the work that in step S402 and step S404, needs to accomplish also comprises: configuration DHCP relaying or agency, the configuration DHCP server ip address makes DHCP relay or agency to communicate with Dynamic Host Configuration Protocol server.

Step S406, the DHCP that Dynamic Host Configuration Protocol server is relevant provides information.

Step S408, DHCP relay or agency provide information to be forwarded to the inner corresponding PC of enterprise network DHCP.

Step S410 is to step S414; PC provides information according to a plurality of DHCP that possibly return, and selects one of them also to send dhcp request message, from this DHCP proxy, obtains the IP address; The industry of going forward side by side is engaged in connecting (if use is dhcp relay feature; Then relaying needs relevant DHCP request is forwarded to relevant Dynamic Host Configuration Protocol server, obtain IP address assignment, thereby flow process is also slightly different with Fig. 4 B).Because this flow process and prior art are similar, do not describe in detail at this.

In concrete realization, can pass through different IP addresses, distinguish different servers and network.And the corresponding PC/ server in each IP address is to realize relevant processing capacity.But this method is with of the prior art to dispose the situation of DHCP and dns server at different enterprise networks the same, is to use also independently that computer carries out the C/S application processes, do not solve the wasting of resources and the problem that realizes sharing.Simultaneously, also brought further problem, for example needed a large amount of IP addresses, particularly under the situation of the enormous amount of enterprise network.

For this reason, can do further optimization on this basis: can use same IP address to come corresponding centralized processing system.This is just the same with present load balancing, and corresponding IP address is gone but its processing can be distributed in many computers.But there is a problem here, how carries out the differentiation of heterogeneous networks,, need realize different processing to different user networks here because different with common load balancing.For this reason, in DHCP relay or agency, need add the code information of relevant enterprise.In fact, can pass through different IP addresses, carry out the differentiation of network, particularly after passing through NAT.And, need do work further is set.For example, to Dynamic Host Configuration Protocol server, service provider and user need one to contract, and are unlikely to have the generation of personation like this, simultaneously, also can obtain further information, and the user is carried out authentication.

The information that the client that also can utilize DHCP Option82 to carry relevant DHCP relay or proxy information is correlated with.Which enterprise Dynamic Host Configuration Protocol server confirms the DHCP request from through the information of the DHCP Option82 that the DHCP relay of enterprise network is perhaps acted on behalf of and added, and is sent to the corresponding processing process and handles, and returns result.Like this, at first solved the related network differentiation, promptly professional problem of isolating.Also can encrypt transmission, with further acquisition than higher fail safe.

Focus on the processing requirements that needs to different users and carry out the virtual of treatment progress.Concrete, the function copy that has a plurality of DHCP to handle in the centralized processing system is perhaps handled instance.The context (CONTEXT) that perhaps has a DHCP to handle to each enterprise network comprises relevant initial configuration and relevant process state information, mainly is the assignment information of IP address, and relevant temporal information etc.Concrete function comprises that one side need be carried out the processing to application, and this is external operation; Simultaneously, also to accomplish managerial operation, for example carry out refreshing of time; On some crucial time points, need notify, perhaps transmission of refresh message etc.; These all are the routine operations that DHPC handles, and are prior aries, do not do further describing among the present invention.

And specific client network and processing instance is related; Through DHCP relay or the Option82 information that sends over of agency, with or relevant IP address information, and CAMEL-Subscription-Information etc.; At first realize the identification of customer network, and further associate with the processing instance of relevant customer network.And centralized processing system through being connected of IP network realization and customer network, can be realized the function associated processing.

Centralized processing system; Some configuration managements, statistics and planning instrument are provided; Work such as the planning that function is carried out in support and statistics also provides relevant management tool, supports the realization and relevant management work that focus on, as DHCP is handled the IP address configuration of instance and the initialization of data etc.

For guaranteeing the high availability of processing capacity; Centralized processing system can be at high performance PC, perhaps PC server, and perhaps the blade server cluster is realized; Certainly; Also can be that the distributed system with high reliability realizes, further can be through carrying out Hot Spare to handling instance, and obtain high availability.

Embodiment three

Fig. 5 is the network structure according to the C/S application of the embodiment of the invention three.As shown in Figure 5; Centralized processing system is by one or multiple pc machine; Perhaps PC server, perhaps blade server connects a network system of forming through Ethernet switch (perhaps many networks that switch is formed); And can further form PC or server cluster or distributed system, to improve the reliability of system.In the centralized processing system, also comprise gateway, be used to connect different customer networks, and ADMINISTRATION SUBSYSTEM, realize management to centralized processing system.

Though the method that in case study on implementation two, provides a kind of DHCP of realization to focus on.But the experience that this a bit not too meets general network design promptly to the DNS and the Dynamic Host Configuration Protocol server of internal network, should be deployed in the inside of network, uses the inner network address, rather than openly gives external network.For this reason, in the present embodiment, another kind of processing method is provided, its with prior art in each enterprise network, separately dispose relevant server category seemingly, satisfy that experience that user network disposes requires and the security requirement of Network Isolation.

Concrete implementation method does, through with the virtual a plurality of virtual machines (VM) that turn to of the computational resource in the centralized processing system, according to the demand of disposal ability, also can be separate host.To each VM; Perhaps main frame can carry out the independent IP address configuration, and further is divided in the different subnet (corresponding different customer networks) and goes; Possibly comprise a plurality of VM or main frame in the sub-net, and the IP address is the address in the corresponding client network.Can come to carry out independently DHCP by client's network manager like this, and/or the installation of dns server and management.

Concrete network is divided, and can combine Fig. 5, between customer network and gateway, sets up independently tunnel, for example through the configuration of the VLAN on the interface (being referred to as outside VLAN), realizes the isolation of different customer networks on gateway.Further; Gateway is through the tunnel in the centralized processing system network, and VLAN (being referred to as inner VLAN) for example is perhaps under the not enough situation of 12 VLAN sign; Further use Q-in-Q (multilayer VLAN) technology (this equally also is applicable to outside VLAN); Realize and being connected of relevant VM, and outside VLAN and inner VLAN are associated, so just realize relevant VM and customer network related in the centralized processing system; Be actually forming a network, thereby realize the processing of relevant C/S function about VM and customer network.Further, can pass through gateway, perhaps on the equipment of the customer network side that is connected with gateway, open ACL (ACL) function, strengthen the safety function of network.

Gateway has: L3 function of exchange and/or acl feature.Stating the L3 function of exchange includes but not limited to: the routing function between functionality of vlan and different VLAN.

And, can realize through the ADMINISTRATION SUBSYSTEM in the centralized processing system to the planning of the disposal ability of concrete VM.Concrete, ADMINISTRATION SUBSYSTEM can be accepted the processing demands that client's C/S uses, and comprises the quantity of VM, the ability of VM, and concrete C/S should function, or the like; Further, ADMINISTRATION SUBSYSTEM can be according to demand, and whether the disposal ability in the inspection centralized processing system satisfies the demands, and under situation about satisfying the demands, return results is given the client.Further, can be through automatic, perhaps the approach of manual configuration realizes the related of VM and customer network.

In the realization case of virtual machine, because the computing capability of centralized processing system still is divided into some independently computers; And be assigned in each customer network and go, therefore, still have the waste of resource; The expense of perhaps installing, managing is bigger, can do further optimization.Concrete, in centralized processing system, operation one cover software systems comprise main program and realize DHCP and the different instances of DNS processing that through different processes, perhaps thread is realized handling.In the different instance to different DHCP and dns server, comprise relevant allocation tables information, and the DNS map information.Because the real-time of DHCP and DNS maybe be not necessarily very strong, perhaps need to handle more timely the configuration process ability handling property parameter relevant suitably, for example reaction time of processing etc. with setting.

Concrete, to different processing instances, need do different differentiations according to the customer network of service.Concrete, can distinguish through the title of different instances.And specifically handle instance, related with customer network can connect through concrete network and realize.Concrete, customer network is through gateway, and the internal interface of gateway; Be connected to the physical interface of some concrete computer systems of centralized processing system; Through this interface, perhaps further possibly be sub-interface, carry out related with the corresponding processing instance; Be about to from this interface, the message that perhaps comes on the sub-interface is transmitted to the corresponding processing instance.Result, the path from same returns to customer network.

Realizing that through the different disposal instance C/S uses under the situation about focusing on, ADMINISTRATION SUBSYSTEM is accepted client's processing request, and is named.Further, ADMINISTRATION SUBSYSTEM provides connection interface to the client, and the client can pass through this interface, further disposes IP address for example, the operations such as data initialization that C/S uses.

What need further specify is that among Fig. 5, relevant network connects, and possibly have the possibility of Single Point of Faliure.This can overcome through following approach, and promptly customer network can connect 2 gateways through 2 networks, and the intercomputer in the centralized processing system, through 2 links, connects 2 measures such as switch, realizes the high reliability of network.Further, can support the realization of high reliability through VRRP (Virtual Router Redundancy Protocol).To the high reliability of C/S application processes, for example can perhaps C/S application processes instance be carried out Hot Spare etc. and realize through the backup of VM.Equally,, can be arranged in the different process and address space, and obtain to isolate, not have influence on the realization of other instances through handling instance for fail safe.In addition, the computer in the relevant centralized processing system can be formed group system, guarantees high reliability.Above-mentioned relevant technologies all is a prior art, can directly quote.

Need to prove; DHCP and DNS are that typical C/S is used, and general C/S uses and have and DHCP and the similar Processing Structure of DNS, just use the data object difference of its processing to concrete C/S; Therefore method of the present invention can be generalized to general C/S and uses.
