In order to provide a network-based data transmission service to a user, a cloud resource operator typically divides a part of on-cloud resources as line resources for data transmission to a user who leases a line, and connects, for example, an off-line data center of the user to the divided line resources through a network switching device, thereby enabling the off-line data center of the user to perform data transmission with other devices through the on-line cloud. However, during the daily use of the user, the network switching device often requires maintenance operations such as software upgrades, troubleshooting, and the like. Such an operation may result in the network switching device being unavailable for a certain period of time and thus in the data transmission service by the subscriber using the line also being interrupted for a certain time. However, it is often important for a user to lease such a line for the tasks or tasks involved in the data transfer service, and thus such a long line disruption is generally unacceptable to the user. However, maintenance work on network switching equipment is also usually unavoidable, and therefore, a solution that has less impact on the time required for a user to use a line for data transmission service is required.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
The scheme provided by the embodiment of the application can be applied to any system with network transmission capability, such as a server system comprising a chip with network transmission function and related components, and the like. Fig. 1a is a schematic view of an application scenario of a line switching scheme provided in an embodiment of the present application, and the scenario shown in fig. 1a is only one example to which the technical scheme of the present application is applicable.
Today, with the rapid development of internet technology, more and more enterprises use the internet to realize mobile offices of employees outside and interconnection and interworking between offices scattered at different places. Particularly, as the degree of informatization of enterprises increases, operations within enterprises do not leave from various terminals and various informatization systems or platforms, for example, emails used by employees of enterprises to various automation systems used for internal operations all need to be supported by the internet, and especially for enterprises with larger scale or enterprises with higher requirements on stability and reliability of information services, the public internet services often cause information transmission blockage and even disconnection. Therefore, more and more enterprises choose the line of data transmission provided by the internet operator as the network foundation of the enterprise. Since such a data transmission line is used solely by a rental company, stability and reliability thereof can be ensured.
Since a cloud service provider has internet resources that allow users at various locations to access, a cloud resource operator typically divides a part of resources on the cloud as line resources for data transmission to users who rent lines for data transmission, and connects, for example, an offline data center of a user to a network switching device of the cloud resource operator to connect to the divided line resources for data transmission, thereby implementing online cloud of the offline data center of the user through data transmission and providing access to personnel at various locations or affiliates. However, during the daily use of the user, maintenance operations such as software upgrade, trouble shooting, etc. are often required for the network switching device. Such an operation may result in the network switching device being unavailable for a certain period of time and thus the line service of the user's data transmission being interrupted for a certain time. However, the tasks or tasks that a user has to hire the line service for data transmission are generally important, and therefore such a time-consuming interruption is generally unacceptable for the user. Maintenance work on network switching equipment is often unavoidable.
Maintenance work on network switching equipment can usually only be done in the prior art by negotiating with the user of the line leasing the data transmission so that the user agrees to stop using the line for the data transmission for a certain period of time. However, this not only affects the important work of the user using the line service for data transmission, but may even bring loss to the user, and also greatly deteriorates the experience of the user using the line service for data transmission.
For example, as shown in fig. 1a, fig. 1a is a schematic diagram illustrating an application scenario example of a line switching method of data transmission according to an embodiment of the present application. In the scenario shown in fig. 1a, a user will typically have their own data center and be provided to local affiliates and employees via the internet. For security reasons, such data centers for users are usually located off-line, for example in an IDC (internet data center) in a special machine room such as a headquarters, and may be connected from the room to a cloud node of a cloud service provider closest to the room, such as to a network switching device provided at the cloud node by the cloud service provider, thereby accessing the user's off-line IDC device to the line resources of the data transmission divided for it by the cloud service provider through the network switching device, therefore, each division company and all employees of the user can use the line resource of the data transmission to access the data on the IDC server under the line in the data transmission line mode by accessing the cloud service platform, and therefore the data safety of the user and the stability and reliability of data communication are guaranteed.
However, as described above, in such a data transmission line service, a network switching device provided by a cloud service provider for a user to access a line resource for data transmission becomes a very important link. All the data of the off-line IDCs need to be used through the network switching device, so that when a cloud service provider needs to perform maintenance work such as upgrading, maintenance or fault repair on the network switching device, the network switching device cannot be used, and a user cannot access the IDC of the user through a data transmission line, thereby causing great influence on daily work of the user.
In this regard, in the prior art, it is also proposed that, instead of the line service for data transmission, the line service for data transmission may be provided to the user in other manners. However, such a solution requires the user to perform special configuration of the alternative, and if a problem occurs in the configuration, the daily work of the user is also affected.
In view of the above, it is also proposed in the prior art that when the network switching device needs to be maintained, a data transmission line can be newly constructed for the user to be used by the user, but such a scheme not only needs to configure the line for the user, but also has a very large overhead for constructing the data transmission line, and a construction period is also long, which also affects the daily work of the user for the user.
In view of this, in the embodiment of the present application, a line switching scheme for data transmission is proposed. For example, as in the scenario shown in fig. 1a, when it is determined that maintenance needs to be performed on the network switching device, a line switching instruction for data transmission may be received by a management server, e.g., a cloud policing server, which may be used to instruct switching of data transmission between a first device, e.g., a cloud server, and a second device, e.g., an offline IDC, from a first line to a second line. Therefore, the cloud platform may determine, for example, through the network controller component, the second line and the network switching device on the line for accepting the data transmission, and send the configuration information on the first line, for example, the configuration information generated for the user's use of the line for the data transmission, to the network switching device on the line for the target data transmission, so that the data transmitted on the first line may be switched to the line for switching the target data transmission for transmission.
For example, the network controller component in the scenario shown in fig. 1a may be a cloud management server for managing lines of respective data transmissions, and the network switching device may be a CSW (cloud access switch), so that when setting up a line service of data transmissions for a subscriber, a local cloud node room of the cloud service provider may be connected from e.g. an offline IDC room of the subscriber using a network line of a network operator, e.g. an optical fiber, to e.g. a CSW device in the room, so that the cloud service provider may divide its on-cloud resources into line resources of data transmissions for connection to the CSW device for use by the tenant. Thus, when an employee of the tenant accesses a cloud server of the cloud service provider in a public network from a foreign location by using tenant information, the cloud server of the cloud platform can recognize the tenant's access and transmit data of the employee, for example, which is intended to be transmitted to the offline IDC room, to a CSW device in a cloud service provider's room to which the offline IDC room is connected through a line resource for data transmission specifically divided therefor, and further to a server in the IDC room through an optical fiber connection between the CSW device and the IDC room.
Therefore, in the data transmission performed by the tenant using the line for data transmission, all data needs to be relayed by the CSW device of the line for data transmission, and therefore, when the CSW device of the line for data transmission has a problem or needs to be upgraded, the data transmission performed by the tenant using the line for data transmission is affected because the CSW device is temporarily unavailable.
For this reason, in the embodiment of the present application, when the CSW device needs to be deactivated due to maintenance performed on the CSW device, the line switching may be performed for the line of data transmission in which the CSW device is located, that is, the data transmission performed by the CSW device is switched to the second line of data transmission in which another CSW device is located. For this reason, when receiving the switching instruction, the network controller of, for example, the cloud management control may determine the line 2 of the data transmission as the switching target according to the switching instruction, and thereby determine the CSW device 2 on the line 2 of the data transmission. After that, the cloud management and control server may issue various pieces of configuration information of the CSW device 1 on the data transmission line 1 to the newly determined CSW device 2. For example, in the embodiment of the present application, the configuration information of the line 1 of the data transmission may be stored in the CSW device 1 of the line 1 of the data transmission, and may include one or more of a virtual routing forwarding configuration, a virtual extended local area network tunnel configuration, a line configuration of a physical data transmission, and a border gateway protocol configuration. Thus, by receiving various pieces of configuration information of the line 1 for data transmission, the CSW device 2 can configure the line 2 for data transmission to be completely identical to the line 1 for data transmission, so that after switching, the user can use the line 2 for data transmission as it is using the line 1 for data transmission without any adjustment and without any influence on the work of the tenant.
After or simultaneously with the configuration information being issued to the CSW device 2, a data transmission channel may be established between the CSW device 1 and the CSW device 2. The data transmission channel can be used for data that still needs to be transmitted on the data transmission line 1 during switching of data transmission on the data transmission line 1 to the data transmission line 2, for example, lower cloud data transmitted to an offline IDC room is transmitted from the CSW device 2 to the CSW device 1 through the data channel. For the sake of security and stability, in this embodiment of the application, a Border Gateway Protocol (BGP) -based neighbor relationship may be established between the CSW device 1 and the CSW device 2, and then a virtual extensible local area network (VXLAN) tunnel may be established between the CSW device 1 and the CSW device 2 as the data transmission channel.
Then, the Router Interface (RI) information of the tenant may be further modified according to the CSW device 2, where the RI information is VXLAN tunnel configuration information and may be used to establish a tunnel data transmission line between XGW and the CSW. In the initial case, the cloud management issues VXLAN tunnel configuration information (e.g., RI information) onto XGW; the RI information contains an IP address of the CSW1, so that when a tenant sends data to an offline IDC through a cloud server, the cloud server can determine that the data needs to be sent to the CSW1 first through the information; when the line switching of data transmission is performed, the cloud management and control server issues the relevant configuration information to the CSW2, and the CSW2 has the same configuration of the tenant as the CSW 1; further, the cloud management and control issues a command to XGW to change the IP address of the network switching device in the RI information of this tenant on XGW from CSW1 to CSW2, so that after the data arrives at XGW, XGW does not forward to CSW1, but instead forwards to CSW 2.
After the configuration of the line 2 for data transmission is completed and the network forwarding device at the cloud server end is changed to the CSW2, since the device in the offline IDC room is still connected to the CSW device 1, for example, XGW, when receiving the offline data sent by the tenant staff through the cloud platform, may send the offline data to the CSW device 2 through the line 2 for data transmission, but since the device in the IDC room is still connected to the CSW device 1, the offline data still needs to be transmitted to the IDC room through the connection between the CSW device 1 and the IDC room. Therefore, the data traffic in the current line 2 may be detected first, and when it is determined that the traffic is not abnormal, the connection between the device in the IDC room and the CSW device 1 may be switched to the CSW device 2, so that the switching from the line 1 for data transmission to the line 2 for data transmission is completed.
In addition, for the cloud data sent from the IDC room to the cloud, the uploading mode can be determined according to the time when the cloud data is sent to the cloud node room. For example, when the upper cloud data is sent to the cloud node computer room, the devices in the computer room are not switched from the CSW device 1 to the CSW device 2, and then the upper cloud data is still transmitted to the CSW device 1 through the data transmission line 1, and the data transmission to the cloud is completed through the data transmission line 1. Conversely, when the cloud data is sent to the cloud node room, the room has been switched from the CSW device 1 to the CSW device 2, the cloud data may be directly transmitted to the CSW device 2 through the data transmission line 2, and when the CSW device 2 receives the cloud data, the data transmission to the cloud is continued through the data transmission line 2.
Therefore, in the whole line switching process of data transmission, only when the connection between the cloud node computer room and the CSW device 1 is switched to the CSW device 2, the data transmission is slightly influenced, other processes have no influence on the line of the tenant using the data transmission, and the time is controlled to be tens of seconds, so that the non-inductive switching of the user can be realized.
In the embodiment of the application, a line management interface can be displayed on a terminal of a line maintenance or management person, so that the line maintenance or management person can know the line condition of data transmission between the cloud server and the offline IDCs of the tenants in time. For example, as shown in fig. 1b, fig. 1b is a schematic diagram illustrating a line management interface according to an embodiment of the present application. A wired line display area may be included in the interface, and is used for displaying a first line currently used by a first device, such as a cloud server, and a second device, such as an offline IDC, for data transmission, and at least one second line to which the data transmission can be switched. For example, the name of the cloud server currently accessed by the tenant and the device identifier of the offline IDC device may be displayed in the line display area, and the device identifier or IP address of the network switching device CSW1 currently used for data transmission between the two devices may also be displayed, and other network switching devices that may be currently used as the second line, such as CSW2 and other available switching devices, may also be displayed. And therefore, the selection of other available network switching devices, i.e., the selection instruction for the at least one second line, by the manager can be received in the area, so that the switching of the above-described lines can be performed according to the selection of the manager.
In addition, the interface may further display a line configuration information display area, which is used to display configuration information of a line currently used for data transmission between the first device, such as the cloud server, and the second device, such as the offline IDC. For example, the configuration information is used to configure a currently used line so that data transmission is performed between the first device and the second device through the line. Thus, the line manager can check the configuration information displayed in the area to confirm whether the configuration information is correct or needs to be modified.
According to the line switching scheme for data transmission provided by the embodiment of the application, by receiving an instruction instructing to switch data transmission between first and second devices from a first line to a second line, a first network switching device used by the first line and a second network switching device used by the second line are determined according to the instruction, configuration information of the first line is sent to the second network switching device to configure the second line, and then the data transmission between the first device and the second device can be switched to the second line. Therefore, the network switching equipment used by the two lines is determined according to the switching instruction, the configuration information of the first line is sent to the network switching equipment used by the second line, so that the network switching equipment can configure the second line to enable the two lines to have the same configuration, then the data transmission between the two equipment is switched to the second line, a user does not need to participate in the switching process, and the line switching can be executed after the configuration information of the first line is sent to the network switching equipment used by the second line, so that the line switching can be completed in a short time, and the influence on the data transmission of the user due to the fact that the network switching equipment in the line currently used by the user is stopped is greatly reduced.
The above embodiments are illustrations of technical principles and exemplary application frameworks of the embodiments of the present application, and specific technical solutions of the embodiments of the present application are further described in detail below through a plurality of embodiments.
Example two
Fig. 2 is a flowchart of an embodiment of a line switching method for data transmission provided in the present application, where an execution subject of the method may be various terminal or server devices with network transmission capability, or may be a device or chip integrated on these devices. As shown in fig. 2, the line switching method for data transmission includes the following steps:
s201, receiving a line switching command.
In step S201, a line switching instruction for data transmission may be received. In this embodiment of the application, when a network switching device on a line for data transmission between a first device, for example, a cloud server, of a current user and a second device, for example, an offline IDC, fails or needs to be disabled for maintenance, a line switching instruction for the data transmission may be received, and the line switching instruction for the data transmission may be used to instruct to switch the data transmission performed between the first device and the second device from the first line to the second line. Therefore, the line identifier of the first line and the line identifier of the second line may be indicated in the line switching instruction.
S202, the first network switching equipment and the second network switching equipment are determined according to the circuit switching instruction.
In step S202, the network switching device for the first data transmission on the first line and the network switching device used in the second line to be switched to may be determined according to the switching instruction received in step S201. For example, in the embodiment of the present application, the line device for the first data transmission and the line device for the second data transmission may be cloud access switch (CSW) devices. Accordingly, in step S202, the device identification of the network switching device used in the first line, for example, CSW1 shown in fig. 1a, and the device identification of the network switching device used in the second line to be switched to, for example, CSW2 shown in fig. 1a, may be determined according to the line switching instruction received in step S201.
S203, configuring the second network switching device by using the configuration information of the first network switching device for the first line.
In step S203, the configuration information of the first line indicated by the line switching instruction of the data transmission received in step S201 may be sent to the second network switching device determined in step S202 to configure the second network switching device. For example, the configuration information may be used to configure a first line so that a first device, such as a cloud server, and a second device, such as an offline IDC, may perform data transmission through the first line and may be stored, for example, in a cloud management server. And in step S203, the configuration information of the first network switching device may be issued to a second network switching device by a cloud management and control server for managing a line for data transmission to configure the second network switching device, so that the second line for data transmission using the second network switching device also has a configuration completely consistent with the first line.
S204, data transmission between the first device and the second device through the first line is switched to the second line.
In step S204, data transmission originally on the first line may be switched to the second line whose configuration has been completed according to the configuration information of the first line transmitted in step S203. Since the second line also has the configuration information in accordance with the first line by transmitting the configuration information of the first line to the second network device used by the second line, for example, the CSW2 in step S203. Therefore, the data transmission originally performed on the first line is switched to the second line in step S204, and seamless switching of tenant data transmission can be achieved. That is, the tenant can use the switched second line for data transmission as it is without any additional configuration of the line. In particular, in a scenario such as that shown in fig. 1a, the tenant offline IDC room is connected by a physical fiber line to a first network switching device, such as the CSW1, used by the first line, so in this case, data transmission can be performed in step S204 by switching the fiber connection of the tenant connected to the CSW1 from the first network switching device to a second network switching device, so that the tenant offline IDC room is also connected to a second line using the second network switching device.
In the line switching method for data transmission provided in the embodiment of the present application, by receiving an instruction instructing to switch data transmission performed between first and second devices from a first line to a second line, a first network switching device used by the first line and a second network switching device used by the second line are determined according to the instruction, and the second network switching device is configured by using configuration information of the first network switching device for the first line, and then the data transmission between the first device and the second device may be switched to the second line. Therefore, the network switching equipment used by the two lines is determined according to the switching instruction, the first network equipment is used for configuring the network switching equipment used by the second line according to the configuration information of the first line, so that the two lines have the same configuration, then the data transmission between the two equipment is switched to the second line without a user participating in the switching process, and the line switching can be performed after the configuration of the network switching equipment used by the second line is completed, so that the line switching can be completed in a short time, and the influence on the data transmission of the user caused by the deactivation of the network switching equipment in the line currently used by the user is greatly reduced.
EXAMPLE III
Fig. 3 is a flowchart of another embodiment of a line switching method for data transmission provided in the present application, and an execution subject of the method may be various terminal or server devices with network transmission capability, or may be a device or chip integrated on these devices. As shown in fig. 3, on the basis of the embodiment shown in fig. 2, the line switching method for data transmission provided in the embodiment of the present application may include the following steps:
s301, receiving a line switching command.
In step S301, a line switching instruction for data transmission may be received. In this embodiment of the application, when a network switching device on a line for data transmission between a first device, for example, a cloud server, of a current user and a second device, for example, an offline IDC, fails or needs to be disabled for maintenance, a line switching instruction for the data transmission may be received, and the line switching instruction for the data transmission may be used to instruct to switch the data transmission performed between the first device and the second device from the first line to the second line. Therefore, the line identification of the first line and the line identification of the second line may be indicated in the line switching instruction.
S302, the first network switching equipment and the second network switching equipment are determined according to the circuit switching instruction.
In step S302, the network switching device for the first data transmission on the first line and the network switching device used in the second line to be switched to may be determined according to the switching instruction received in step S301. For example, in the embodiment of the present application, the line device for the first data transmission and the line device for the second data transmission may be cloud access switch (CSW) devices. Accordingly, in step S302, the device identification of the network switching device used in the first line, for example, CSW1 shown in fig. 1a, and the device identification of the network switching device used in the second line to be switched to, for example, CSW2 shown in fig. 1a, may be determined according to the line switching instruction received in step S301.
S303, configuring the second network switching device by using the tenant configuration information of the first network switching device for the first line.
In step S303, the tenant configuration information of the first line indicated by the line switching instruction of the data transmission received in step S301 may be transmitted to the second network switching device determined in step S302 according to the first line. For example, the tenant configuration information may be information that a tenant currently using a first line for data transmission configures the first line so that a first device such as a cloud server and a second device such as an offline IDC may perform data transmission through the first line, and the tenant configuration information may be stored in, for example, a cloud management server. In an embodiment of the present application, the tenant configuration information may include: one or more of virtual route forwarding configuration, virtual extended local area network tunnel configuration, line configuration of physical data transmission, and border gateway protocol configuration. In step S303, the tenant configuration information of the first network switching device may be issued to the second network switching device by the cloud management and control server for managing the line for data transmission, so that the second line for data transmission using the second network switching device also has a tenant configuration completely consistent with the first line.
S304, a data transmission channel is established between the first network switching equipment and the second network switching equipment.
After or simultaneously with the sending of the tenant configuration information to the second network switching device in step S303, a data transmission channel may be established between the first network switching device and the second network switching device in step S304. The data transmission channel may be used to relay data transmitted from the first device to the second device in the process of switching data transmission performed on the first line to the second line.
For security and stability considerations, in step S304, a Border Gateway Protocol (BGP) -based neighbor relationship may be established between the first network switching device and the second network switching device, and further a virtual extensible local area network (VXLAN) tunnel may be established between the first network switching device and the second network switching device.
S305, setting a network switching device used for downlink data transmission from the first device to the second device as a second network switching device.
S306, the network switching device used for data transmission of the second device is set as the second network switching device.
When switching a line used for data transmission between the first device and the second device, since the data switching is performed by using the network switching device, in step S305, the network switching device used for sending data to the offline IDC, for example, may be changed from the first network switching device to the second network switching device, and the connection between the offline IDC and the first network switching device may be maintained. Accordingly, the first device may transmit data to the second network switching device and to the first network switching device through the data transmission channel established between the second network switching device and the first network switching device in step S304, and then transmitted to the offline IDC by the first network switching device.
In step S305, the network switching device used by the first device to send data to the second device may be changed to the second network switching device by modifying the peer IP address in the RI information of the first device from the IP address of the first network switching device to the IP address data of the line device for the second data transmission.
Thereafter, the network switching device used by the second device for data transmission may be set as the second network switching device in step S306. For example, the off-line IDC may be connected to the optical fiber in the cloud node room and switched from the first network switching device to the second network switching device, so that the switching of the data transmission from the first line to the second line is completed.
In the line switching method for data transmission provided in the embodiment of the present application, by receiving an instruction instructing to switch data transmission performed between a first device and a second device from a first line to a second line, a first network switching device used by the first line and a second network switching device used by the second line are determined according to the instruction, and the second network switching device is configured by using configuration information of the first network switching device for the first line, and then, data transmission between the first device and the second device may be switched to the second line. Therefore, the network switching equipment used by the two lines is determined according to the switching instruction, the network switching equipment used by the second line is configured by the first network equipment according to the configuration information of the first line, so that the two lines have the same configuration, then the data transmission between the two equipment is switched to the second line without the participation of a user in the switching process, and the line switching can be executed after the configuration of the network switching equipment used by the second line is completed, so that the line switching can be completed in a short time, and the influence on the data transmission of the user caused by the deactivation of the network switching equipment in the line currently used by the user is greatly reduced.
Example four
Fig. 4 is a schematic structural diagram of an embodiment of a data transmission system provided in the present application, which may be used to execute the line switching method for data transmission shown in fig. 2 or fig. 3. As shown in fig. 4, the data transmission system may include a transmission management server 41, a first network switching device 42, and a second network switching device 43.
The transmission management server 41 may be configured to determine the first network switching device 42 and the second network switching device 43 according to the line switching instruction, configure the second network switching device 43 using the configuration information of the first network switching device 42 for the first line, and switch data transmission between the first device and the second device from the first line to the second line.
In the embodiment of the present application, the transmission management server 41 may be a cloud management server for managing lines of respective data transmission, and the network switching devices 42 and 43 may be CSWs (cloud access switches), so that when setting a line service of data transmission for a subscriber, a network line, such as an optical fiber, of a network operator may be connected from, for example, an offline IDC room of the subscriber to a local cloud node room of the cloud service provider, such as to a CSW device in the room, so that the cloud service provider may divide line resources of data transmission from its on-cloud resources to connect to the CSW device for use by the tenant. Thus, when an employee of the tenant accesses a cloud server of the cloud service provider in a public network from a foreign location by using tenant information, the cloud server of the cloud platform can recognize the tenant's access and transmit data of the employee, for example, which is intended to be transmitted to the offline IDC room, to a CSW device in a cloud service provider's room to which the offline IDC room is connected through a line resource for data transmission specifically divided therefor, and further to a server in the IDC room through an optical fiber connection between the CSW device and the IDC room.
For this reason, in the embodiment of the present application, when it is necessary to deactivate the network switching device 42 of the first line currently used between the first device and the second device of the user due to maintenance of the device, the transmission management server 41 may determine the second line of data transmission as a handover target according to the handover instruction, and thereby determine the second network switching device 43 used by the second line of data transmission. Thereafter, the transmission management server 41 may issue various pieces of configuration information of the first line to the newly determined second network switching device 43 to configure the same. For example, in the embodiment of the present application, the configuration information of the first line may be stored in the first network transmission device 42, and may include one or more of a virtual route forwarding configuration, a virtual extended local area network tunnel configuration, a line configuration for physical data transmission, and a border gateway protocol configuration. Therefore, the transmission management server 41 can configure the second line to be consistent with the first line by transmitting various pieces of configuration information of the first line to the second network switching device 43 used by the second line, so that after the switching, the user can use the second line as it is using the first line without any adjustment and without any influence on the work of the tenant.
After or simultaneously with the configuration information being issued to the second network switching device 43, a data transmission channel may be established between the first network switching device 42 and the second network switching device 43. The data transmission channel may be used for transmitting data still required to be transmitted on the first line, for example, lower cloud data transmitted to the off-line IDC, from the second network switching device 43 to the first network switching device 42 through the data channel in the process of switching the data transmission of the first line to the second line. For security and stability, in the embodiment of the present application, a Border Gateway Protocol (BGP) -based neighbor relationship may be established between the first network switching device 42 and the second network switching device 43, and then a virtual extensible local area network (VXLAN) tunnel may be established between the first network switching device 42 and the second network switching device 43 as the data transmission channel.
Then, the Router Interface (RI) information of the tenant may be further modified according to the second network switching device 43, where the RI information is VXLAN tunnel configuration information and may be used to establish a tunnel data transmission line between XGW and the CSW. In an initial situation, the transmission management server 41 issues VXLAN tunnel configuration information (e.g., RI information) to the first device, where the RI information may include an IP address of the first network switching device 42, so that when a tenant sends data to an offline IDC through a cloud server, the cloud server may determine that the data needs to be sent to the first network switching device 42 first through the information; when switching the data transmission line, the transmission management server 41 issues the relevant configuration information to the second network switching device 43, where the second network switching device 43 has the same configuration of the tenant as the first network switching device 42; further, the transmission management server 41 issues a command to the first device to change the IP address of the network switching device in the RI information of the tenant on the first device from the first network switching device 42 to the second network switching device 43.
After the configuration of the second line is completed and the network forwarding device of the first device is changed to the second network switching device 43, since the device in the offline IDC room is still connected to the first network switching device 42, for example, when the first device receives the offline data sent by the tenant staff through the cloud platform, the offline data can be sent to the second network switching device 43 through the second line, but since the device in the IDC room is still connected to the first network switching device 42, the offline data still needs to be sent to the IDC room through the connection between the first network switching device 42 and the IDC room. Therefore, the data traffic in the current second line may be detected first, and when it is determined that no abnormality occurs in the traffic, the connection between the second device and the first network switching device 42 may be switched to the second network switching device 43, so that the switching from the first line to the second line for data transmission is completed.
In the data transmission system provided in the embodiment of the present application, the transmission management server determines, according to the line switching instruction, the first network switching device used by the first line and the second network switching device used by the second line, and configures the second network switching device using the configuration information of the first line, and then may switch data transmission between the first device and the second device to the second line. Therefore, the transmission management server determines the network switching equipment used by the two lines according to the switching instruction, and uses the configuration information of the first line to configure the network switching equipment used by the second line, so that the two lines have the same configuration, and then switches the data transmission between the two equipment to the second line without the user participating in the switching process, and can perform the line switching by sending the configuration information of the first line to the network switching equipment used by the second line, so that the line switching can be completed in a short time, and the influence on the data transmission of the user caused by the deactivation of the network switching equipment in the line currently used by the user is greatly reduced.
