In the switched-line data transmission apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the data transmission device of the switched line of the present invention may be provided in the data transmission device of the switched line, which calls the data transmission program of the switched line stored in the memory 1005 through the processor 1001 and executes the data transmission method of the switched line provided by the embodiment of the present invention.
An embodiment of the present invention provides a data transmission method for a switching line, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the data transmission method for a switching line according to the present invention.
In this embodiment, the data transmission method for the switching line includes the following steps:
step S10: the method comprises the steps of obtaining a service data packet sent by an application server, and determining an opposite-end external system corresponding to the service data packet.
It can be understood that the main execution body of this embodiment is a data transmission device for switching a line, where the data transmission device for switching a line may be an electronic device such as a computer and a server, and may also be a routing device such as a router and a gateway device, and this embodiment takes an Nginx host as an example for description.
It should be noted that the service data packet is a data packet corresponding to transmitted service data, the service data packet includes address information corresponding to an external device at the opposite end, and the external system at the opposite end is a device that receives the service data packet. The application server of the embodiment is arranged in an SF region of a network system, that is, a region where an intranet application and a core application are deployed, and a client accesses the application server through a DMZ isolation region in an internet form to acquire related data. And when receiving the service data packet, the application server sends the application data packet to the Nginx host computer arranged in the partner area, so that the external system is accessed through the Nginx host computer.
Specifically, in order to improve the transmission efficiency of the service data packet, the step S10 includes: sending a data packet request to an application server according to a preset receiving type, wherein the application server feeds back a service data packet when determining that the service type of the service data packet is matched with the receiving type corresponding to the data packet request; and receiving a service data packet sent by the application server, and determining an opposite-end external system corresponding to the service data packet.
It should be understood that, referring to fig. 3, fig. 3 is a schematic system layout diagram of an embodiment of a data transmission method for a switching line according to the present invention; in this embodiment, a plurality of nginn hosts are provided, the external system is provided with a private network address and a VPN network address, and each of the nginn hosts is also provided with different access ports for accessing the private network address and the VPN network address of the external system, respectively. Optionally, each of the nginn hosts is configured to transmit service data packets of different service types, and when the application server obtains the service data packet, the application server selects a corresponding target nginn host according to a service type corresponding to the service data packet, and sends the service data packet to the nginn host. And each Nginx host receives the service data packet sent by the application server according to a preset receiving type, wherein the service type of the received service data packet is matched with the receiving type. Optionally, in another implementation manner, the nginnx host feeds back the running state to the application server every preset period, and the application server selects a target nginnx host with an optimal running state according to the running states of the plurality of nginnx hosts and transmits the service data packet to the target nginnx host.
It should be noted that, when receiving a service data packet, the application server determines a type corresponding to the service data packet, and configures different identifiers for service data packets of different service types, where the service types may be distinguished according to actions performed by services, for example: inquiry, payment and the like, and can also be distinguished according to the size of the service data packet, for example, a data packet larger than 2Mb is marked as a packet with large data volume, and if the data volume of the service data packet is large, an idle Nginx host is selected for transmission.
Step S20: and determining a private network route and a VPN network route corresponding to the opposite-end external system.
It can be understood that the private line service is mostly oriented to enterprises, governments and other customers with higher data access/interconnection requirements and higher service requirements, has fixed network IP addresses, and does not need access authentication. VPN is a communication method commonly used for connecting private networks between medium-sized and large-sized enterprises or groups, and achieves private message security effects such as confidentiality, sender authentication, message accuracy and the like by using a Tunneling Protocol (Tunneling Protocol). In this embodiment, the nginnx host configures different network routes to access virtual IP addresses of the external system of the peer end, respectively.
Specifically, the step S20 includes: determining a private network address and a VPN network address corresponding to the opposite-end external system; determining a private network route according to a preset private network interface and the private network address; and determining the VPN network route according to a preset VPN network interface and the VPN network address.
It should be noted that, in this embodiment, the peer external system provides corresponding virtual IP service addresses and ports to the private line and the VPN as needed, for example: the virtual IP address corresponding to the VPN network is set to be 10.88.4.44, and the virtual IP address corresponding to the private network is set to be 10.88.4.45. Optionally, address information corresponding to each external system is stored in each proxy host, and a corresponding mapping relation table or database is queried according to information corresponding to the opposite-end external system to obtain a corresponding private network address and a corresponding VPN network address. In a specific implementation, the nginn host determines a private network address and a VPN network address corresponding to the peer external system through interaction with the peer external system, and sets a network interface for accessing different networks in advance, for example, setting an eth0 network interface for accessing the VPN network address, and setting an eth1 network interface for accessing the private network address. Referring to fig. 3, taking an 10.49.195.253 host as an example, the host is configured with the following routes:
route add-net 10.88.4.44gw 172.30.0.254netmask 255.255.255.255eth1；
the net identifies a virtual IP address, gw represents a gateway, netmask represents a subnet mask, and eth1 represents a preset private network interface, that is, a service accessed 10.88.4.44 through a current route will perform data transmission through the private network.
Step S30: and selecting a route to be transmitted from the private network route and the VPN network route according to a preset selection strategy.
It can be understood that the preset selection policy may configure a private network address and a VPN network address for the Nginx host using openness, automatically detect whether the private network route is available, and perform data transmission by using the VPN network route when the private network route is abnormal. Optionally, the preset selection policy is to select a network route with a large communication capacity for transmission, perform a communication capacity test by using ping (network diagnostic tool) according to the private network address and the VPN network address, determine the communication capacity states corresponding to the private network and the VPN network, and select a network route with a large communication capacity for transmission. Optionally, the preset selection policy is to select a corresponding network route according to a service type corresponding to the service data packet.
Step S40: and transmitting the service data packet to the opposite-end external system through the route to be transmitted.
It can be understood that, when a VPN network route is selected for data transmission, the embodiment uses an open-VPN technology to transmit the service data packet to the external system at the opposite end. Configuring a forwarding mechanism in advance, configuring a route to be transmitted, and automatically sending the service data packet according to the corresponding forwarding mechanism. In this embodiment, the internal application service forwards the access request through the proxy (nginx) in the partner area, thereby accessing the external system through the private line + VPN.
In the embodiment, a service data packet sent by an application server is obtained, and an opposite-end external system corresponding to the service data packet is determined; determining a private network route and a VPN network route corresponding to an external system of an opposite terminal; selecting a route to be transmitted from the private network route and the VPN network route according to a preset selection strategy; and transmitting the service data packet to an opposite-end external system through the route to be transmitted. Through the mode, the double lines of the special line and the VPN network are used for data transmission, the cost is lower compared with a mode of taking the special line as a standby line, a proper line is selected from the special line and the VPN network for data transmission, automatic line switching is achieved, and the line switching is simple and intelligent.
Referring to fig. 4, fig. 4 is a flowchart illustrating a data transmission method for a switching line according to a second embodiment of the present invention.
Based on the first embodiment, the step S30 of the data transmission method for switching lines in this embodiment includes:
step S301: and carrying out network speed test on the private network route and the VPN network route to determine the corresponding communication quantity of the private network route and the corresponding communication quantity of the VPN network route.
Step S302: and selecting a route with large connecting quantity from the private network route and the VPN network route as a route to be transmitted.
It can be understood that, in this embodiment, a ping (network diagnostic tool) is used to perform network speed test on the private network route and the VPN network route, determine the communication quantity of the private network and the VPN network, and select a route with a large communication quantity as a route to be transmitted.
In the embodiment, a service data packet sent by an application server is obtained, and an opposite-end external system corresponding to the service data packet is determined; determining a private network route and a VPN network route corresponding to an external system of an opposite terminal; carrying out network speed test on the private network route and the VPN network route to determine the corresponding communication quantity of the private network route and the corresponding communication quantity of the VPN network route; selecting a route with large connecting capacity from private network routes and VPN network routes as a route to be transmitted; and transmitting the service data packet to an opposite-end external system through the route to be transmitted. By the mode, a high-quality line with large connecting quantity is selected from the private network route and the VPN network route for data packet transmission, the data packet transmission quality and the network stability are guaranteed, the VPN network is automatically selected for data transmission when the private network fails, the line utilization rate is improved, automatic line switching is achieved, and the line switching is simple and intelligent.
Referring to fig. 5, fig. 5 is a flowchart illustrating a data transmission method for a switching line according to a third embodiment of the present invention.
Based on the first embodiment, the step S30 of the data transmission method for switching lines in this embodiment includes:
step S303: and determining the service type corresponding to the service data packet.
It can be understood that, when receiving a service data packet, the application server determines the type corresponding to the service data packet, and configures different identifiers for the service data packets of different service types, and when receiving the service data packet, the nginx host determines the identifier corresponding to the service data packet, so as to determine the corresponding service type.
Step S304: and searching the corresponding transmission requirement according to the service type.
It should be noted that, transmission requirements corresponding to different service types are preset, and the service types and the transmission requirements are stored in a mapping relation table or a database, for example, the payment service type needs to ensure high stability, and the transmission requirement corresponding to the payment service type is set to use a stable dedicated route for data transmission. And when the corresponding transmission requirement is not found, the transmission is carried out through the private network route by default, and if the transmission is abnormal, the VPN route is automatically switched to.
Step S305: and selecting a route meeting the transmission requirement from the private network route and the VPN network route as a route to be transmitted.
It should be understood that the transmission requirement carries identification information corresponding to the private network route or the VPN network route, and the corresponding route to be transmitted is determined according to the transmission requirement.
Further, to avoid data loss caused by network anomaly, automatic route switching is further implemented, after step S40, the method further includes: when the transmission abnormity is detected, stopping transmitting data through the route to be transmitted; and switching the network route, and transmitting the service data packet to the opposite-end external system through the switched network route.
It should be noted that, if an abnormality occurs when the service data packet is transmitted through the private network route, the network is switched to the VPN network route for transmission, and if an abnormality occurs when the service data packet is transmitted through the VPN network route, the network is switched to the private network route for transmission, thereby ensuring the network stability.
Further, the step S40 includes: acquiring preset forwarding configuration information, wherein the preset forwarding configuration information at least comprises allowable failure times and connection time limit; transmitting the service data packet to the opposite-end external system through the route to be transmitted according to the preset forwarding configuration information;
when the transmission abnormality is detected, stopping data transmission through the route to be transmitted, including: when the connection establishment time length with the opposite-end external system is longer than the connection time limit, determining that the connection fails; and when the connection failure times are larger than the allowable failure times, judging that the transmission is abnormal, and stopping transmitting data through the route to be transmitted.
It is understood that forwarding configuration information is configured in advance, for example:
in this embodiment, the allowed failure times are 0 times, the connection time is 5 seconds, if the connection time with the external system of the opposite terminal is longer than 5 seconds, the connection is determined to be failed this time, the connection failure times are 1 time, and the connection failure times are greater than the allowed failure times, it is determined that transmission abnormality is detected, and the network route for transmitting data is switched.
In the embodiment, a service data packet sent by an application server is obtained, and an opposite-end external system corresponding to the service data packet is determined; determining a private network route and a VPN network route corresponding to an external system of an opposite terminal; determining a service type corresponding to the service data packet; searching a corresponding transmission requirement according to the service type; selecting a route meeting the transmission requirement from the private network route and the VPN network route as a route to be transmitted; and transmitting the service data packet to an opposite-end external system through the route to be transmitted.
