Description
Technical field
The present invention relates to the communications field, at the processing method and concentration of a kind of client/server application
Reason system.
Background technology
In current typical IP network deployment and application, to realize the convenient application of network, DHCP is typically all deployed with
(Dynamic Host Configuration Protocol, DHCP) server and DNS (Domain Name
System, domain name system) server, realize the automatic distribution of IP address respectively, and domain name parsing, enter so as to save user
The complicated configuration of row, or remember some network address for being difficult memory.In general, in each network, being required for carrying out this
The deployment of sample, it is simply otherwise varied in scale.For example in INTERNET networks, there are multiple DNS root servers, be very heavy
The network function wanted is disposed, it is necessary to high reliability measure be taken, to ensure the high availability of network.And in a small-scale intranet
Then can be a PC server in network, to realize the function of relevant address distribution and parsing.Certainly, it is probably to dns resolution
The structure of stratification, it is not further here to be considered.User network be planned, disposed by Subscriber Unit oneself, with
And in the case of management, these functions are each completed by the network manager of user completely.According to the demand of function, Yi Jixing
The demand of energy, can use different device levels, and corresponding Reliability Measures.
Fig. 1 is typical DHCP and dns server application deployment schematic diagram in a network.In each network (enterprise in figure
Network) in, due to using and managing convenient consideration, DHCP and dns server will be deployed with.Subscriber computer/PC is (general
Need to do some settings in an operating system) after power, it is necessary first to IP address is obtained automatically, and this comes generally by DHCP
Realize, URL (Uniform Resource Locator, unified resource positioning required for then being parsed by dns server
Symbol)/domain name IP address, pass through IP messages realize communication.Because the IP address allocative decision in each network is different, and not
Server in same enterprise network, may take different addressing/nomenclature schemes, therefore DHCP and dns server, there is difference
Database, although its processing function is the same, you can be realized by using identical software systems.
But, under a kind of new applicable cases, particularly under the background that cloud computing is progressively popularized, the network of user is
There is provided and realize by the business of operator, i.e., enterprise customer no longer needs enterprise customer oneself to go to buy, dispose and manage
The relevant network facilities, and relevant network application function deployment is carried out, and directly from service provider there, obtain relevant
Network and some basic network application functions.And from the point of view of operator, it is outer in the basic network connection for providing user network,
Also need to respectively each user network (customer network) and independent DHCP and DNS functions are provided, because the IP of each user
Address is planned, and the domain name planning of some built-in systems is very different, unlikely carries out reality by set of system
It is existing, and further also have the demand in terms of network security, it is necessary to isolate to network.
So, one it is obvious, it is respectively that each user network provides independent that also strictly feasible solution, which is,
DHCP and dns server, to realize relevant function, just with client oneself realize network when as.
But, this implementation has its irrational place.For example, in the case where current network design is put into practice, needing
Substantial amounts of PC/ servers are wanted to realize relevant function, thus it is unreasonable in the matching of function, and often disposal ability is remote
Asked more than actually required, cause certain wasting of resources, in addition, it is necessary to manage so many server/computer/PC, managed
Managing cost also can be higher.

High availability.
Embodiment two
Fig. 4 A are the network structure of according to embodiments of the present invention two C/S applications, as shown in Figure 4 A, the network structure bag
Enterprise network 1 and enterprise network 2 are included, enterprise network 1 and enterprise network 2 can access ISP/INTERNET networks.Wherein, in enterprise
A DHCP relay is respectively arranged with network 1 and enterprise network 2 or agency (applies, to DNS due to realization mechanism not
Together, it is not necessary to make proxy settings, and directly by the IP network mechanism of bottom, to realize the direct forwarding of message), DHCP generations
Reason is connected to a centralized processing system, and the centralized processing system includes Dynamic Host Configuration Protocol server and dns server.
Wherein, Dynamic Host Configuration Protocol server and dns server can be one, either multiple pc machine or PC server or knife
Piece server, or the computer system specially designed, can constitute group system or distributed system., this needs basis
Disposal ability and determine about the size of database.
In the present embodiment, DHCP is realized by distributing public IP address to the processing server in centralized processing system
Focus on.
Because PC is before IP address is obtained, it is necessary to which sending DHCP finds (broadcast) message, DHCP processing of the prior art
Flow is as shown in Fig. 2 step S202 to 210：Dynamic Host Configuration Protocol server, receives the DHCP and finds message, and carry out processing return one
DHCP provides information, and PC provides information according to the multiple DHCP that may be returned, and selection is one of to send dhcp request message,
From the Dynamic Host Configuration Protocol server, IP address is obtained.Because this handling process is prior art, it is not described in detail herein.
In general, DHCP and DNS are in small-/medium-sized Intranet, and do not need too many disposal ability, in other words, with mesh
The disposal ability of preceding PC, the entirely possible DHCP and DNS for meeting multiple networks processing requirement.And examining in terms of reliability
Consider, due to that can be realized by disposing the relevant mechanism such as multiple Dynamic Host Configuration Protocol server, and active and standby dns server.But,
Because the configuration of each network is different, additionally, due to the consideration of secure context, this disposal ability must be isolation,
It cannot influence each other.Therefore, network share realize in the case of, can just focus on, and must realize it is safe every
From.A kind of implementation is, by the public IP address of operator, Dynamic Host Configuration Protocol server to be realized to configure.In this manner it is possible to solve
Relevant Network Isolation problem.
Because Dynamic Host Configuration Protocol server is not in enterprise network, DHCP application messages need to be sent in external network,
Therefore during focusing on, relevant requirements of process makes a change.Fig. 4 B are according to embodiments of the present invention two C/S applications
DHCP process charts, as shown in Figure 4 B, comprise the following steps：
Step S402, inside enterprise network, the relevant DHCP relay of configuration or agency, by DHCP relay or agency
Message is found to collect relevant DHCP.
DHCP is had found that message is forwarded to the Dynamic Host Configuration Protocol server of external network by step S404, DHCP relay or agency.Its
In, DHCP relay or agency have found to carry relevant attribute classification, such as DHCP in message in transmitted DHCP
Option82。
Wherein, the work completed is needed also to include in step S402 and step S404：Configuration DHCP is relayed or acted on behalf of,
Configuration DHCP server ip address so that DHCP relay or agency can be communicated with Dynamic Host Configuration Protocol server.
Step S406, Dynamic Host Configuration Protocol server related DHCP provide information.
DHCP is provided the corresponding PC that information is forwarded to inside enterprise network by step S408, DHCP relay or agency.
Step S410 to step S414, PC provide information according to the multiple DHCP that may be returned, and select one of those simultaneously
Dhcp request message is sent, IP address is obtained from the DHCP proxy, and carry out service connection (if using DHCP relay
Function, then relaying need by relevant DHCP request be forwarded to correlation Dynamic Host Configuration Protocol server, obtain IP address distribution, thus flow with
Fig. 4 B are also slightly different).Because the flow is similarly to the prior art, no further details to be given herein.
, can be by different IP address, to distinguish different servers and network in concrete implementation.And it is each
One PC/ server of individual IP address correspondence, to realize relevant processing function.But, this method with it is of the prior art not
DHCP is disposed as the situation of dns server with enterprise network, or is carried out using independent computer at C/S applications
Reason, the problem of not solving the wasting of resources and realize shared.Meanwhile, further problem is also brought, for example, is needed a large amount of
IP address, particularly in the case of the enormous amount of enterprise network.
Therefore, can be further optimized on this basis：Same IP address can be used to be focused on to correspond to
System.This just as current load balancing, corresponds to an IP address, but its processing can be distributed in multiple stage computers
Go.But have a problem that how to carry out the differentiations of heterogeneous networks here, because different with common load balancing,
Need exist for realizing different processing for different user networks.Therefore, it is necessary to which adding has in DHCP relay or agency
Close the code information of enterprise.Indeed, it is possible to by different IP address, to carry out the differentiation of network, particularly pass through NAT
Afterwards.Furthermore, it is desirable to do further setting work.For example, to Dynamic Host Configuration Protocol server, service provider and user need a label
About, so it is unlikely to the generation for having personation, it is also possible to obtain further information, authentication is carried out to user.
It can also be carried using DHCP Option82 about the related letter of the client of DHCP relay or proxy information
Breath.Dynamic Host Configuration Protocol server is by the DHCP relay of enterprise network or agency and additional DHCP Option82 information come really
DHCP request is determined from which enterprise, and is sent to corresponding treatment progress being handled, and return to result.So, first
Solve related network differentiation, i.e., the problem of business is isolated.Transmission can also be encrypted, further to obtain higher peace
Quan Xing.
Focus on the virtualization for needing that treatment progress is carried out for the processing requirement of different users.Specifically, concentrating
There are the function copy of multiple DHCP processing, or processing example in processing system.Or have one to each enterprise network
The context (CONTEXT) of DHCP processing, including about initial configuration and relevant process state information, mainly IP
The distribution information of location, and relevant temporal information etc..Specific function includes, and on the one hand needs to carry out the processing to application, this
It is external operation；Meanwhile, the operation of management aspect is also completed, for example, the refreshing of time is carried out, in some crucial times
, it is necessary to be notified on point, or refresh message transmission etc., these are all the routine operations of DHPC processing, are prior arts,
It is not described further in the present invention.
And the association of specific client network and processing example, the Option82 sended over by DHCP relay or agency
Information, and or relevant IP address information, and signing information etc., realize the identification of customer network first, and further and have
The processing example for closing customer network is associated.And centralized processing system, the connection with customer network is realized by IP network, i.e.,
Relevant function treatment can be achieved.
Centralized processing system is supported to carry out planning and the statistics of function there is provided some configuration managements, statistics and Planning Tool
Deng work and relevant management tool is provided, support the realization that focuses on and related management work, such as to DHCP processing in fact
IP address configuration and the initialization of data of example etc..
For ensure processing function high availability, centralized processing system can in high performance PC, or PC server, or
Person's blade server cluster is realized, it is of course also possible to be the distributed system with high reliability to realize, further can be with
By carrying out Hot Spare to processing example, and obtain high availability.
Embodiment three
Fig. 5 is the network structure of according to embodiments of the present invention three C/S applications.As shown in figure 5, centralized processing system is
By either multiple pc machine or a PC server, or blade server, pass through Ethernet switch (or many exchanges
Machine composition network) connection and constitute a network system, and can further constitute PC or server cluster or
It is distributed system, to improve the reliability of system.In centralized processing system, in addition to gateway, the different client for connecting
Network, and management subsystem, realize the management to centralized processing system.
Although realizing the method that DHCP is focused on there is provided a kind of in case study on implementation two.But, this is a little less accorded with
The experience of network design as unification, i.e. DNS and Dynamic Host Configuration Protocol server to internal network, it should be deployed in the inside of network,
Using the internal network address, rather than it is disclosed to external network.Therefore, there is provided another processing side in the present embodiment
Method, it meets the experience of user network deployment with individually disposing relevant server category seemingly in each enterprise network in the prior art
It is required that and Network Isolation security requirement.
Concrete implementation method is, by the way that the computing resource in centralized processing system is virtually turned into multiple virtual machines
(VM), according to the demand of disposal ability or independent main frame.To each VM, or main frame, it can carry out independent
IP address is configured, and is further divided into different subnet (the different customer network of correspondence), in a possible subnet
Including multiple VM or main frame, and IP address is the address in corresponding customer network.So can by client network pipe
Reason person independently carries out DHCP, and/or dns server installation and management.
Specific network is divided, and can be combined Fig. 5, between customer network and gateway, be set up independent tunnel, for example, lead to
The VLAN configurations (being referred to as outside VLAN) crossed on interface, to realize isolation of the different clients network on gateway.Further, net
The tunnel passed through in centralized processing system network is closed, such as VLAN (is referred to as internal VLAN), or identified in the VLAN of 12
In the case of not enough, further using Q-in-Q (multilayer VLAN) technology (this can equally be well applied to outside VLAN), to realize
With the connection about VM, and outside VLAN and inside VLAN are associated, thus realized relevant in centralized processing system
VM and customer network association, are actually that will constitute a network about VM and customer network, so as to realize relevant C/S functions
Processing.Further, it is possible to by gateway, or in the equipment of the customer network side connected with gateway, unlatching ACL (accesses control
List processed) function, carry out the security function of Strengthens network.
Gateway has：L3 functions of exchange and/or acl feature.L3 functions of exchange are stated to include but is not limited to：Functionality of vlan and
Routing function between different VLAN.
And the planning of the disposal ability to specific VM, can be by the management subsystem in centralized processing system come real
It is existing.Specifically, management subsystem, can receive the process demand of the C/S applications of client, include VM quantity, VM ability, tool
The C/S of body should function, etc.；Further, subsystem is managed, the processing in centralized processing system can be checked according to demand
Ability, if meet demand, in the case where meeting demand, returns result to client.Further, it is possible to by automatic, or
The approach of manual configuration, realizes the association of VM and customer network.
Case is realized in virtual machine, due to the computing capability of centralized processing system, is still divided into some independences
Computer, and be assigned in each customer network, therefore, still may there is a waste of resource, or install, management is opened
Pin can be further optimized than larger.Specifically, in centralized processing system, running a set of software systems, including main journey
Sequence and the different instances for realizing DHCP and DNS processing, processing is realized by different processes, or thread.To different
In the different examples of DHCP and dns server, including relevant allocation tables information, and DNS map informations.Due to
DHCP and DNS real-time, may be not necessarily very strong, or needs more timely to handle, and can properly configure processing energy
The power process performance parameter relevant with setting, such as the reaction time of processing.
Specifically, to different processing examples, it is necessary to do different differentiations according to the customer network of service.Specifically, can
Distinguished with the title by different examples.And specifically handle example, and customer network association, specific net can be passed through
Network connects to realize.Specifically, customer network is connected to centralized processing system by the internal interface of gateway, and gateway
The physical interface of some specific computer system, by the interface, or is probably further sub-interface, and corresponding processing
Example is associated, and the message that will come from the interface, or sub-interface is transmitted to corresponding processing example.Result,
From same path, customer network is returned to.
In the case where realizing that C/S applications are focused on by different disposal example, subsystem is managed, receives the place of client
Reason request, and be named.Further, management subsystem is there is provided connection interface to client, and client can be entered by the interface
Row is further to be configured, such as IP address, the operation such as data initialization of C/S applications.
It should be further stated that, in Fig. 5, relevant network connection, it is understood that there may be the possibility of Single Point of Faliure.This can
To be overcome by following approach, i.e., customer network can be by 2 network connections, 2 gateways, and focus on and be
Intercomputer in system, passes through 2 links, the measure such as 2 interchangers of connection, to realize the high reliability of network.Further, may be used
To support the realization of high reliability by VRRP (Virtual Router Redundancy Protocol).To the high reliability of C/S application processing, example
Such as can be by VM backup, or Hot Spare etc. is carried out to C/S application processing examples realized.Equally, for security,
Can be by the way that exemplary setup will be handled in different processes and address space, and isolated, have no effect on other examples
Realization.In addition, about the computer in centralized processing system, group system can be constituted, it is ensured that high reliability.It is above-mentioned relevant
Technology, is all prior art, can directly be quoted.
It should be noted that DHCP and DNS are typical C/S applications, and general C/S is applied and had and DHCP and DNS
Similar processing structure, it is different using the data object of its processing just for specific C/S, therefore the method for the present invention, can
To be generalized to universal C/S applications.
