Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a processing method and a centralized processing system for a client/server application. In a typical IP network deployment and application, a DHCP (Dynamic Host Configuration Protocol) server and a DNS (Domain Name System) server are generally deployed for the convenience of the network. Realize the automatic allocation of IP addresses and the resolution of domain names, thus eliminating the need for users to perform complex configurations or memorizing network addresses that are difficult to remember. In general, such a deployment is required in every network, but only in terms of scale. For example, in an INTERNET network, there are multiple DNS root servers, which are very important network function deployments and require high reliability measures to ensure high availability of the network. In a small business network, it can be a PC server to implement address allocation and parsing. Of course, DNS resolution may be a hierarchical structure, and no further consideration is given here. In the case where the user network is planned, deployed, and managed by the user unit itself, these functions are completely performed by the user's network administrator. Depending on the needs of the function and the performance requirements, different equipment levels and corresponding reliability measures can be used. Figure 1 is a schematic diagram of a typical DHCP and DNS server deployed in a network. In each network (the enterprise network in the figure), DHCP and DNS servers are deployed due to ease of use and management. User computer / PC (usually need to do some settings in the operating system) After power-on, you first need to obtain the IP address automatically, which is usually implemented by DHCP, and then parse the required URL through the DNS server (Uniform Resource Locator, Uniform Resource Locator) / IP address of the domain name, which communicates through IP packets. Since the IP address allocation schemes in different networks and the servers in different enterprise networks may adopt different addressing/naming schemes, DHCP and DNS servers have different databases, although their processing functions are the same, that is, This can be achieved by using the same software system. However, in a new application situation, especially in the context of the gradual popularization of cloud computing, the user's network is realized through the service provision of the operator, that is, the enterprise user no longer needs the enterprise user to purchase, deploy and Manage relevant network facilities and perform related network application function deployments, and directly obtain relevant network and some basic network application functions from service providers. From the perspective of the operator, in addition to providing the basic network connection of the user network, it is also necessary to provide separate DHCP and separate for each user network (customer network). DNS function, because the IP address planning of each user, and the domain name planning of some internal systems are very different, it is unlikely to be implemented through a system, and there is still a need for network security, which needs to be isolated from the network. . In this way, an obvious and indeed feasible solution is to provide separate DHCP and DNS servers for each user network to implement the relevant functions, just as the client implements the network itself. However, this kind of implementation has its unreasonable place. For example, in the current network deployment practice, a large number of PCs/servers are required to implement related functions, so that the matching of functions is unreasonable, and often the processing capability is far more than the actual demand, resulting in a certain waste of resources. In addition, the need to manage so many servers / computers / PCs, management costs will be higher.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. FIG. 3 is a flowchart of processing a C/S application according to the first embodiment of the present invention. As shown in FIG. 3, the method includes the following steps: Step S302: The centralized processing system receives C/S application messages from different customer networks. . Step S304, the centralized processing system processes the received C/S application message. Step S306, the centralized processing system returns the processing result to the corresponding customer network. In this embodiment, by centrally processing C/S applications from various customer networks, the problem of waste of resources of the C/S application server is solved, thereby achieving the effects of reducing management costs and improving management efficiency. The customer network may be an enterprise network, or a network that needs to perform the C/S application processing, or a subnet (later). Set up a service relay or proxy in the enterprise network, such as a DHCP relay or proxy; The centralized processing system is located on the external network and is specified by using a public IP address. The service agent uniformly sends the message about the C/S application to the centralized processing system. For other C/S applications, such as DNS, it can be directly processed through the underlying IP network without special proxy or relay mechanism, ie when there is an IP network connection between the customer network and centralized processing, ie The relevant processing can be implemented. The service relay or the proxy in the enterprise network carries the network identifier information about the enterprise network in the sent C/S application packet. The centralized processing system combines the egress IP address of the enterprise network and related attribute categories, such as DHCP Option 82, or the port number of the protocol, to distinguish different networks to implement different processing. The centralized processing system may be one, or multiple/a group of PCs or PC servers, or a blade server, or a specially designed computer system, which may be a cluster system or a distributed system. The centralized processing system can implement multiple C/S processing instances to implement the processing and management of the C/S applications of the relevant customer networks, while ensuring high availability of the system. Embodiment 2 FIG. 4A is a network structure diagram of a C/S application according to Embodiment 2 of the present invention. As shown in FIG. 4A, the network structure includes an enterprise network 1 and an enterprise network 2, and the enterprise network 1 and the enterprise network 2 are accessible. ISP/INTERNET network. Among them, a DHCP relay or proxy is set in the enterprise network 1 and the enterprise network 2 respectively (for the DNS application, since the implementation mechanism is different, the proxy setting is not required, and the packet is directly implemented through the underlying IP network mechanism. Direct forwarding), the DHCP agent is connected to a centralized processing system, which includes a DHCP server and a DNS server. The DHCP server and the DNS server may be one, or multiple PCs or PC servers, or blade servers, or specially designed computer systems, which may form a cluster system or a distributed system. This needs to be determined based on processing power and the size of the database in question. In this embodiment, the public IP address is allocated to the processing server in the centralized processing system.

Centralized processing of DHCP. Because the PC needs to send a DHCP discovery (broadcast) message before obtaining the IP address, the DHCP processing procedure in the prior art is as shown in steps S202 to 210 of FIG. 2: The DHCP server receives the DHCP discovery message and performs The processing returns a DHCP providing information, and the PC selects one of the DHCP providing information, and selects one of them to send the DHCP request information, and obtains an IP address from the DHCP server. Since this processing flow is prior art, it will not be described in detail herein. In general, DHCP and DNS do not require much processing power in small and medium-sized networks. That is to say, with the processing power of current PCs, it is possible to meet the processing requirements of DHCP and DNS of multiple networks. Reliability considerations can be achieved by deploying multiple DHCP servers, as well as active and standby DNS servers. However, since the configuration of each network is different, and due to security considerations, this processing capability must be isolated and cannot affect each other. Therefore, in the case of network sharing implementation, centralized processing is possible, and secure isolation must be achieved. One implementation is to implement a DHCP server through the carrier's public IP address. In this way, the related network isolation problem can be solved. Because the DHCP server is not located in the enterprise network, DHCP application messages need to be sent to the external network. Therefore, in the process of centralized processing, the relevant processes need to be changed. 4B is a flowchart of DHCP processing of a C/S application according to Embodiment 2 of the present invention. As shown in FIG. 4B, the method includes the following steps: Step S402: Configure a DHCP relay or proxy in the enterprise network, by DHCP. Follow the agent or agent to collect information about DHCP discovery. Step S404, the DHCP relay or the proxy forwards the DHCP discovery message to the DHCP server of the external network. The DHCP relay agent or the proxy carries the related attribute category in the sent DHCP discovery packet, for example, the DHCP Option 82o. The work to be completed in the step S402 and the step S404 further includes: configuring a DHCP relay or proxy, configuring DHCP The server IP address allows the DHCP relay or proxy to communicate with the DHCP server. Step S406, the DHCP server provides information related to the DHCP server. Step S408, the DHCP relay or the proxy forwards the DHCP providing information to the corresponding inside the enterprise network.

PC. Step S410 to step S414, the PC selects one of the plurality of DHCP providing information that may be returned, and sends the DHCP request information, obtains an IP address from the DHCP proxy, and performs a service connection (if the DHCP relay function is used, Then the relay needs to forward the relevant DHCP request to the relevant DHCP server to obtain the IP address allocation, so the flow is slightly different from FIG. 4B. Since this process is similar to the prior art, it will not be described in detail herein. In a specific implementation, different servers and networks can be distinguished by different IP addresses. And each IP address corresponds to a PC/server to implement the relevant processing functions. However, this method is the same as the case of deploying DHCP and DNS servers in different enterprise networks in the prior art, or using a separate computer for C/S application processing, and does not solve the problem of resource waste and sharing. At the same time, it brings further problems, such as the need for a large number of IP addresses, especially in the case of a large number of corporate networks. To this end, further optimization can be done on this basis: The same IP address can be used to correspond to the centralized processing system. This is the same as current load balancing, corresponding to an IP address, but its processing can be distributed to multiple computers. But there is a problem here, how to distinguish between different networks, because it is different from ordinary load balancing, here need to implement different processing for different user networks. To do this, in the DHCP relay or proxy, you need to add code information about the enterprise. In fact, it can be done by different IP addresses. The distinction between networks, especially after passing NAT. Also, further setup work is required. For example, for a DHCP server, the service provider and the user need a contract, so that there is no counterfeiting, and further information can be obtained to authenticate the user. DHCP Option 82 can also be used to carry customer-related information about DHCP relay or proxy information. The DHCP server determines which enterprise the DHCP request comes from through the DHCP relay or proxy of the enterprise network and the information of the additional DHCP Option 82, and sends it to the corresponding processing process for processing, and returns the processing result. In this way, the problem of network differentiation, that is, service isolation, is first solved. Encrypted transmission can also be performed to further obtain higher security. Centralized processing requires virtualization of the processing process for different user processing requirements. Specifically, there are multiple copies of the DHCP processed function in the centralized processing system, or processing instances. Or there is a DHCP processing context (CONTEXT) for each enterprise network, including information about the initial configuration and related processing status, mainly the allocation information of the IP address, and related time information. The specific functions include: on the one hand, the processing of the application is required, which is an external operation; at the same time, the management operation is also completed, for example, the time is refreshed, and at some critical time points, notification or refresh is required. The transmission of messages, etc., are all conventional operations of DHPC processing and are prior art and will not be further described in the present invention. The association between the specific customer network and the processing instance, the Option 82 information sent by the DHCP relay or the proxy, and the related IP address information, and the subscription information, etc., first realize the identification of the customer network, and further process the processing instance of the relevant customer network. Linked up. The centralized processing system realizes the related function processing by realizing the connection with the customer network through the IP network. Centralized processing system, provides some configuration management, statistics and planning tools, supports function planning and statistics, and provides related management tools to support centralized processing and related management tasks, such as configuring IP address for DHCP processing instances. And initialization of data, etc. In order to ensure high availability of processing functions, the centralized processing system can be implemented in a high-performance PC, or a PC server, or a cluster of blade servers. Of course, it can also be implemented as a distributed system with high reliability, and further Process instances for hot backups for high availability. Embodiment 3 FIG. 5 is a network structure diagram of a C/S application according to Embodiment 3 of the present invention. As shown in FIG. 5, the centralized processing system is a network system composed of one or more PCs, or a PC server, or a blade server, connected by an Ethernet switch (or a network composed of multiple switches), and can be Further forming a PC Or server clusters or distributed systems to improve system reliability. The centralized processing system also includes a gateway, which is configured to connect different customer networks, and a management subsystem to implement management of the centralized processing system. Although a method of implementing centralized DHCP processing is provided in the second embodiment. However, this is somewhat inconsistent with the general network deployment experience, that is, the internal network's DNS and DHCP servers should be deployed inside the network, using internal network addresses instead of being exposed to external networks. To this end, in the present embodiment, another processing method is provided, which is similar to the prior art in which the related server is separately deployed in each enterprise network, and meets the experience requirements of the user network deployment and the security requirements of the network isolation. The specific implementation method is: by virtualizing the computing resources in the centralized processing system into multiple virtual machines (VMs), and depending on the processing capability, it may also be an independent host. For each VM, or host, independent IP address configuration can be performed, and further divided into different subnets (corresponding to different customer networks), possibly including multiple VMs or hosts in one subnet, and the IP address is The address in the corresponding customer network. This allows the client's network administrator to independently install and manage DHCP, and/or DNS servers. For specific network division, you can establish independent tunnels between the customer network and the gateway, for example, through VLAN configuration on the interface (called external VLAN) to isolate different customer networks on the gateway. Further, the gateway further uses Q-in-Q (multi-layer VLAN) technology by centrally processing tunnels in the system network, such as VLANs (referred to as internal VLANs), or when 12-bit VLAN identification is insufficient. The same applies to external VLANs) to connect to the VM and to associate the external VLAN with the internal VLAN. This enables the central processing of the association between the VM and the client network, which is actually related to the VM and the client. The network forms a network to handle the processing of C/S functions. Further, the security function of the network can be enhanced by opening an ACL (Access Control List) function through a gateway or a device on the client network side connected to the gateway. The gateway has: L3 switching function and / or ACL function. The L3 switching functions include but are not limited to: VLAN functions and routing functions between different VLANs. The planning of the processing power of a specific VM can be realized by a management subsystem in the centralized processing system. Specifically, the management subsystem can accept the processing requirements of the client's C/S application, including the number of VMs, the capabilities of the VM, the specific C/S functions, and the like; further, the management subsystem can check according to requirements. Centralize the processing power in the system to meet the demand, and return the result to the customer if the demand is met. Further, the association between the VM and the customer network can be realized through an automatic or manual configuration. In the virtual machine implementation case, due to the computing power of the centralized processing system, it is still divided into independent computers and distributed to each customer network. Therefore, there may still be waste of resources, or installation and management overhead. Larger, can be further optimized. Specifically, in a centralized processing system, running a set of soft The system, including the main program and different instances of DHCP and DNS processing, is handled by different processes, or threads. Different instances of different DHCP and DNS servers include related address allocation table information, as well as DNS mapping information. Due to the real-time nature of DHCP and DNS, it may not be very strong, or it may require relatively timely processing. The processing capability and setting related processing performance parameters, such as the processing response time, may be appropriately configured. Specifically, different processing instances need to be differentiated according to the customer network of the service. Specifically, it can be distinguished by the names of different instances. The specific processing example, the association with the customer network, can be achieved through a specific network connection. Specifically, the customer network is connected to the physical interface of a specific computer system of the centralized processing system through the gateway and the internal interface of the gateway, and is associated with the corresponding processing instance through the interface, or further, may be a sub-interface, The interface or the packet sent from the sub-interface is forwarded to the corresponding processing instance. Process the results, returning to the customer network from the same path. In the case of centralized processing of C/S applications through different processing instances, the management subsystem accepts the client's processing request and names it. Further, the management subsystem provides an interface interface to the client, and the client can perform further configuration through the interface, such as an IP address, data initialization of the C/S application, and the like. It should be further explained that, in Figure 5, there may be a possibility of a single point of failure for the relevant network connection. This can be overcome by the following methods: the customer network can connect two gateways through two networks, and centrally process the computers in the system, connect two switches through two links, and so on, to achieve high network reliability. Sex. Further, high reliability implementation can be supported by VRRP (Virtual Router Redundancy Protocol). The high reliability of the C/S application processing can be realized, for example, by backup of the VM or by performing hot backup of the C/S application processing instance. Similarly, for security, isolation can be achieved by arranging processing instances in different processes and address spaces without affecting the implementation of other instances. In addition, the computers in the centralized processing system can form a cluster system to ensure high reliability. The above related technologies are all prior art and can be directly cited. It should be noted that DHCP and DNS are typical C/S applications, and the general C/S application has a processing structure similar to that of DHCP and DNS, but the data objects processed by the specific C/S application are different, so this The inventive method can be extended to popular C/S applications.

The customer network may be an enterprise network, and a service agent, such as a DHCP relay or proxy, is set in the enterprise network; the centralized processing system is located on the external network, and is specified by using a public IP address. The service agent uniformly sends the message about the C/S application to the centralized processing system. The service proxy in the enterprise network carries the network identifier information about the enterprise network in the C/S application packet that is sent. The centralized processing system combines the egress IP address of the enterprise network and related attribute categories, such as DHCP Option 82, to distinguish different networks to implement different processing. The centralized processing system can be a cluster system or a distributed system. In the centralized processing system, multiple C/S processing instances can be implemented to implement processing and management of C/S applications of different customer networks, and at the same time ensure high system. Availability. The centralized processing system can support different IP addresses and different network configurations, and can achieve isolation between different networks.
