Description
Technical Field
The invention belongs to the field of data processing, and particularly relates to a routing data processing method and device.
Background
The routes are divided into manually configured static routes and dynamic routes generated by a routing algorithm. The dynamic routing can be dynamically generated through the exchange of routing information only by carrying out protocol initial configuration, and can be changed by self-adapting to the topology. Common dynamic Routing protocols include Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Intermediate-to-Intermediate (ISIS) system, Routing Information Protocol (RIP), and the like.
In order to realize the cooperative work of multiple routing protocols, the three-layer network device may use a route redistribution (route redistribution) technology to advertise the learned route of one routing protocol through another routing protocol, so that all network devices in the network topology can be connected.
When a user accesses a certain website through a Domain Name at a client, the client needs to first obtain an IP (Internet Protocol Address) corresponding to the Domain Name by using a DNS (Domain Name System) technology, and then use the IP to construct a data packet to access a target website. When a data packet passes through a three-layer network device, the forwarding of the data packet can be realized only if the three-layer network device has a route related to the IP.
Static routes to the IP can be configured on the three-layer network equipment, and the IP data packet forwarding is realized. However, some domain names may correspond to a plurality of IP addresses, and these IP addresses are not fixed and are updated at regular intervals. The way to configure static routes is less efficient.
After configuring a domain name routing rule in the prior art, the domain name is periodically subjected to DNS analysis, and an actual route is generated according to the analyzed IP.
The main drawbacks of the prior art are: (1) the domain name is regularly subjected to DNS analysis and routing update, and the problems caused by the DNS analysis are as follows: during periodic DNS resolution, the IP corresponding to the domain name has changed, but the route is not updated. The traffic loss can be caused in the time interval, and the service is influenced; (2) the configured domain name routing rule can only take effect in the current network equipment and can not be linked with other network equipment. When the network topology is large, the workload of management configuration is large and errors are easy to occur.
In view of the above problems, no effective solution has been proposed.

In accordance with an embodiment of the present invention, there is provided a method embodiment of a method of routing data processing, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flowchart of a method for processing routing data according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S102, determining the address route of the routing network according to the corresponding relation between the domain name and the address of the target server accessed by the client;
step S104, distributing the address route to all routing devices in the routing network by using a dynamic routing protocol;
and step S106, receiving an access request of the client through the target routing equipment, and sending the access request to the target server according to the address route, wherein the routing equipment is any routing equipment in the routing network.
Through the steps, the address route of the routing network is determined according to the corresponding relation between the domain name and the address of the target server accessed by the client; distributing the address route to all routing devices in the routing network by using a dynamic routing protocol; the access request of the client is received through the target routing equipment, the access request is sent to the target server according to the address route, wherein the routing equipment is any routing equipment in the routing network, and the purpose of timely updating the address route corresponding to the domain name by all the routing equipment in the network is achieved by dynamically sending the address route to all the routing equipment in the routing network, so that the technical effect of improving the data processing efficiency of three-layer network equipment is achieved, and the technical problems that in the related technology, routing data are processed by using a route re-distribution technology through middle three-layer network equipment, the process is complex, and the efficiency is low are solved.
The executing agent of the above steps may be a control device or a processing device, and the executing agent may control a routing network to which the client is connected. One or more addresses corresponding to the domain name may be provided, and the domain name and the corresponding address may not be fixed. The corresponding relation between the domain name and the address can be obtained by sending a domain name resolution request to a resolution server by a client, sending a response message by the resolution server, determining an address route according to the corresponding relation between the domain name and the address, and accessing a target server by the client according to the address route. The address route can be distributed to all the routing devices in the routing network, in order to facilitate communication among the routing devices, all the routing devices in the routing network can be configured with the same dynamic routing protocol, and because the adjacent routing devices (namely, the adjacent routing devices) can directly communicate, the address route can be sent to the adjacent routing devices by the routing devices, and then the address route of the domain name is distributed to all the routing devices in the network in a mode of being sent to the adjacent routing devices of the adjacent routing devices by the adjacent routing devices. Compared with the prior art that the policy routing is set on each routing device, the address routing can be automatically, quickly and efficiently distributed to all the routing devices through the dynamic routing protocol in a mode of dynamically acquiring the address routing through the policy routing, the problems of complex flow and low efficiency caused by the fact that the routing is set on the routing devices one by one are solved, and the problem that the policy routing mode is difficult to realize under the condition that more routing devices exist in a routing network, namely the routing network has larger topology is solved.
For the corresponding relation between the domain name and the address in the response message sent by the resolution server, because the address corresponding to the domain name is not fixed, the corresponding relation can also be distributed to all routing devices in the network by using a dynamic routing protocol, the corresponding relation between the domain name and the address in the response message can also be updated by monitoring, if a new response message of the domain name is monitored, the corresponding relation between the domain name and the address in the response message can be updated to the network routing device by using the dynamic routing protocol, and therefore the address routing in the network routing device is updated. The method solves the problems that in the prior art, the corresponding relation between the domain name and the address is regularly updated, when the network topology structure is large, the routing is not updated timely in the scene that the domain name and the corresponding address change frequently, and the management and maintenance of routing equipment are complicated.

The dynamic Routing Protocol may be OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), ISIS (ISIS-Intermediate to Intermediate system), and RIP (Routing Information Protocol), where when an address route is distributed to all Routing devices in a Routing network by using the dynamic Routing Protocol, it is First ensured that all the Routing devices have the same dynamic Routing Protocol, and the address route can be distributed to all the Routing devices by using the dynamic Routing Protocol.
The target routing device may be any routing device in a routing network, the target routing device is connected to a client, receives an access request from the client through the target routing device, sends the access request to the target server according to the address route, and when the client sends a data request to the server, the data request may first access the target routing device, enter the routing network through the target routing device, jump to a gateway device of the routing network through a plurality of routing devices in the routing network, and send the data request to the server according to the address route through the gateway device. The method achieves the purpose that all the routing devices in the network update the address routes corresponding to the domain names in time by dynamically sending the address routes to all the routing devices in the routing network, achieves the technical effect of improving the data processing efficiency of the three-layer network devices, and further solves the technical problems of complex flow and low efficiency in the prior art that the routing data is processed by using a route redistribution technology through the middle three-layer network devices.
Optionally, before distributing the address route to all routing devices in the routing network by using a dynamic routing protocol, the method further includes: configuring domain name routing of a domain name, wherein the domain name routing comprises the domain name and a target address to which a target server accessing the domain name needs to jump; the domain name route is distributed to all routing devices in the routing network via a dynamic routing protocol.
Before address routing is distributed to all routing devices in a routing network by using a dynamic routing protocol, domain name routing of a domain name can be configured, and next hop address information of the domain name routing and the domain name routing can be configured, so that when a device or a user terminal carries out a domain name access request, the access request of the client terminal can be sent to a target server through one hop or multiple hops by using a next hop address gateway of the domain name routing. In order to facilitate information transfer in the routing device or route hopping between routing devices on the network, the same dynamic routing protocol may be configured in the routing devices.
The domain name route can also be distributed to adjacent neighbor routing devices in the routing network through a dynamic routing protocol configured in the routing device, and the domain name route can be distributed to all the routing devices in the routing network by the neighbor routing devices in a mode of being redistributed to the neighbor routing devices of the neighbor routing devices.
Specifically, in the routing module, a domain name based routing rule (abbreviated as domain name routing) is configured, where a domain name and a next hop ip address need to be specified. The routing module informs the data processing module of the domain name information. Based on the routing redistribution technology, in the dynamic routing module, a dynamic routing protocol is configured to redistribute the domain name routing. The dynamic routing module informs the re-distribution domain name routing information to the routing module.
The domain name routing is sent to all the routing devices in the routing network by using a dynamic routing protocol, so that the purpose of synchronizing the domain name routing of the domain name to all the network devices in the network topology is achieved, and the technical effect of improving the communication speed of the domain name routing of the network devices is achieved.
Optionally, before determining the address route of the routing network according to the correspondence between the domain name and the address of the target server accessed by the client, the method further includes: initiating a domain name resolution request to a resolution server through a client, wherein the domain name resolution request is used for requesting the resolution server to perform resolution on a domain name of a target server to obtain a corresponding address; acquiring a response message of an analysis server to a domain name analysis request; and determining the corresponding relation between the domain name and the address according to the response message, wherein the response message comprises the domain name and the corresponding address.
The resolution server can respond to a domain name resolution request sent by the client, resolve the domain name sent by the client into an address corresponding to the domain name, when the client accesses the address according to the domain name, the domain name resolution is required to be carried out on the domain name to obtain a corresponding network address, a domain name resolution request can be initiated to the resolution server through the client, the domain name resolution request of the client jumps to the gateway device of the routing network through the target routing device in the routing network by single or multiple jumps, the gateway device can enter the public network through the next hop address of the gateway, and sends the domain name resolution request to the resolution server through single or multiple network address jumps on the public network, the resolution server can resolve the domain name of the target server in the domain name resolution request to obtain the corresponding network address, and a response message with a corresponding relationship between the domain name and the address of the domain name resolution can be sent out.
Optionally, determining an address route of the routing network according to a correspondence between a domain name and an address of the client accessing the target server includes: and determining the address route of the routing network according to the domain name route and the address corresponding to the domain name.
And determining an address route of the routing network according to the corresponding relation between the domain name and the address of the target server accessed by the client, wherein the address route utilizes network equipment which can be used for the client to access or transmit data to the target server.
Optionally, after distributing the address route to all the routing devices in the routing network by using a dynamic routing protocol, the method further includes: monitoring a response message of the analysis server; acquiring a new response message under the condition that the analysis server sends the new response message is monitored; determining a new corresponding relation according to the new response message; and distributing the new corresponding relation to all routing devices in the routing network through a dynamic routing protocol.
The monitoring device can determine a new corresponding relation according to a new influence message, namely the corresponding relation between the domain name of the target server and the address corresponding to the domain name, and can distribute the new corresponding relation to the routing device in the routing network through a dynamic routing protocol under the condition that the monitoring device monitors that the analysis server sends a new response message if the client initiates a new domain name analysis request. And after receiving the new corresponding relation, the routing equipment in the routing network updates the stored address route according to the new corresponding relation.
For example, after a client initiates a DNS request for domain name resolution, based on a DNS snooping (also referred to as the above monitoring device) technique, the data processing module may monitor a DNS response packet returned by the DNS server, and obtain a corresponding relationship between a domain name and an IP. And if the domain name is configured to be the domain name route, notifying the routing module of the IP corresponding to the domain name. After receiving the IP information corresponding to the domain name, the routing module generates an actual IP route corresponding to the domain name route using the IP information and notifies the dynamic routing module of the actual IP route. The dynamic routing module advertises these IP routes to the dynamic routing protocol's neighbors, which can generate routes to the domain IP throughout the network topology.
The corresponding relation of the response message of the resolution server is distributed to all the routing devices in the network, so that the purpose of distributing the corresponding relation of the domain name to the routing devices in the whole network topology is achieved, and the technical effect of improving the connectivity of all the network devices in the three-layer network device to the domain name address is achieved.
Optionally, distributing the new correspondence to all routing devices in the routing network via a dynamic routing protocol includes: determining the new corresponding relation and the difference between the corresponding relations, wherein the difference comprises a new address and a deleted address corresponding to the domain name; and distributing the difference to all routing devices in the routing network through a dynamic routing protocol, wherein the routing devices generate a new corresponding relation according to the difference and the stored corresponding relation under the condition of receiving the difference.
In the process of distributing the new corresponding relation to all the routing devices in the routing network through the dynamic routing protocol, the difference between the correspondence of the domain name and the address for domain name resolution and the original correspondence may also be compared, the difference can be that the new corresponding relation in the new response message is added to the original corresponding relation, or the original corresponding relation does not exist on the new corresponding relation, or the new corresponding relation is the same as the original corresponding relation, if the new corresponding relation in the new response message is added to the original corresponding relation, a new address route can be generated, if the original corresponding relation does not exist in the corresponding relation of the new response message, the address route of the corresponding relation which is not stored in the new corresponding relation of the original corresponding relation can be deleted, if the new corresponding relation is the same as the original corresponding relation, no processing can be carried out, and therefore the purpose of updating the address route in the network equipment is achieved.
Specifically, after the client initiates a new DNS request for domain name resolution, the data processing module continues to monitor a DNS response packet returned by the DNS server, and obtains a corresponding relationship between the domain name and the IP. If the domain name is configured as domain name routing and the IP information corresponding to the domain name is changed, the data processing module notifies the routing module of the IP information after updating the domain name. Because the IP address corresponding to the domain name is not unique, the IP information may include a plurality of IP addresses, and after receiving the new IP information corresponding to the domain name, the routing module compares the original IP information corresponding to the domain name, and processes the IP information according to three conditions: (1) for the IP addresses in the new IP information but not in the original IP information, generating IP routes corresponding to the IP addresses; (2) for the IP addresses in the original IP information but not in the new IP information, deleting the IP routes corresponding to the IP addresses; (3) and for the IP addresses in the new IP information and the original IP information, no processing is carried out, and the IP routes corresponding to the IP addresses are reserved.
The corresponding relation of the domain name is updated to the routing equipment in the network in time through the corresponding relation of the new response message of the monitoring and analyzing server, the updating efficiency of the corresponding relation of the domain name and the address of the routing equipment is improved, and the technical effect of improving the processing speed of network service data is achieved.

The target routing device may be any routing device connected to the client, and is configured to complete a routing address hopping function of a request or a response received from the current network client, where the target routing device receives a data access request from the client, may send the access request to the gateway device via the routing device in the routing network according to an address route in the target routing device, and may send the access request from the client to a target address through the gateway device, where the target address may be a next hop address where the routing network sends the access request to the Internet in the public network, and then sends the access request to the target server through one or more hops on the public network.
It should be noted that the present application also provides an alternative implementation, and the details of the implementation are described below.
The present embodiment provides a domain name route generation method based on DNS Snooping, and aims to provide a domain name route generation method based on DNS Snooping, which is convenient for management and maintenance, and is used for solving the problem that the management and maintenance of a middle three-layer network device route are complicated in a scenario where a network topology is large and an IP (Internet Protocol Address) corresponding to a domain name frequently changes.
The present embodiment relates to a routing module, a dynamic routing module, and a data processing module, and fig. 2 is a schematic diagram of a system overall framework according to the embodiment of the present invention, and as shown in fig. 2, a specific processing procedure of the present embodiment is as follows:

(6) After receiving the IP information corresponding to the domain name, the routing module generates an actual IP route corresponding to the domain name route using the IP information and notifies the dynamic routing module of the actual IP route.
(7) The dynamic routing module advertises these IP routes to the dynamic routing protocol's neighbors, which can generate routes to the domain IP throughout the network topology.
(8) After the client initiates a new DNS request domain name resolution, the data processing module continues to monitor a DNS response message returned by the DNS server to acquire the corresponding relation between the domain name and the IP. If the domain name is configured as a domain name route and the IP information corresponding to the domain name is changed, the data processing module notifies the route module of the IP information after updating the domain name, and the IP information may include a plurality of IP addresses due to the fact that the IP address corresponding to the domain name is not unique.
(9) After receiving the new IP information corresponding to the domain name, the routing module compares the original IP information corresponding to the domain name, and processes the new IP information according to three conditions:
