Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a data transmission system according to a data transmission method provided by an embodiment of the present invention. As shown in fig. 1, the data transmission system may include: a second server 110 and a plurality of first servers 120 connected to the second server 110. The second server 110 is configured to manage the first server 120, and both the second server 110 and the first server 120 may be a server, a server cluster composed of a plurality of servers, or a cloud computing service center. Alternatively, the first server 120 may be any other SoC or Central Processing Unit (CPU) having an Internet Protocol (IP) address. Also, the first server 120 has only one port, or only one port of the first server 120 is available for transmitting data, i.e. only one port is used for out-of-band processing.
The second server 110 and the first server 120 may be connected via a switch. In the data transmission system, first data may be transmitted between a plurality of first servers 120, and second data may be transmitted between the second server 110 and the first servers 120. Optionally, the first data may be service data, and the service data may be used to implement communication services between multiple first servers 120, for example: the first server 120 can implement business functions such as computing services or WEB applications based on the business data. The second data may be management data for the second server 110 to manage the first server 120, such as: the second server 110 may monitor the operation status of the first server 120 based on the management data, or assign an IP address to the first server 120, or the like.
An embodiment of the present invention provides a data transmission method, which may be applied to the first server 120 in the data transmission system shown in fig. 1, where the embodiment of the present invention takes a first target server as an example to describe the first target server, and the actions of other first servers 120 may refer to the actions of the first target server, and the first target server is any one of a plurality of first servers, as shown in fig. 2, the method may include:
And 203, constructing a second VLAN where the virtual network card is located based on the virtual network card.
And step 204, sending the first data to other first servers connected with the first target server through the first VLAN.
In summary, in the data transmission method provided in the embodiment of the present invention, a first VLAN is constructed based on a physical network card in a plurality of first servers, a virtual network card is configured in a first target server based on the physical network card in the first target server, a second VLAN where the virtual network card is located is constructed based on the virtual network card, and first data is sent to other first servers connected to the first target server through the first VLAN, and second data is sent to the second server through the second VLAN.
An embodiment of the present invention provides a data transmission method, which may be applied to the first server 120 in the data transmission system shown in fig. 1, where the embodiment of the present invention is described by taking as an example that the first target server and the first target server have one internet access, and the actions of the other first servers 120 may refer to the first target server, and the first target server is any one of a plurality of first servers, as shown in fig. 3, the method may include:
A Virtual Local Area Network (VLAN) is a group of logical devices and users, which are not limited by physical locations and can be organized according to functions, departments, applications, and other factors. Due to the communication between these devices and users, these devices and users can be considered to be in the same network segment, and thus the organized network is referred to as a virtual local area network. VLAN is a relatively new technology that works at layers 2 and 3 of the Open System Interconnection (OSI) reference model, one VLAN can be considered as a broadcast domain, and communication between VLANs is accomplished through a layer 3 router. Compared with the traditional local area network technology, the VLAN technology is more flexible and has the following advantages: the management overhead of the movement, addition and modification of network equipment is small, and the network equipment can control broadcast activities and improve the security of the network.
Generally, before executing this step 301, the hardware deployment of the data transmission system is completed, that is, the servers included in the data transmission system and the hardware connection relationship between the servers are determined, for example: it is determined that the data transmission system includes a second server and a plurality of first servers, each of the first servers is connected to the second server, and the plurality of first servers are connected to each other through a switch, the switch supports the VLAN technology, and the second server and each of the first servers are configured with a physical network card, at this time, the implementation manner of step 301 may include: a first VLAN is constructed based on the physical network card in the switch and each first server to prepare for data transmission in the data transmission system.
Optionally, the first target server may configure the virtual network card based on the physical network card in the first target server according to an instruction for configuring the virtual network card sent by the user to the first target server.
The first target server and the second server may be connected through a switch supporting the VLAN technology, and a virtual network card is also configured in the second server, at this time, an implementation manner of step 303 may include: and constructing a second VLAN based on the switch, the virtual network card in the first target server and the virtual network card in the second server.
Optionally, the first target server may construct the second VLAN based on the virtual network card in the first target server and the virtual network card in the second server according to a VLAN configuration command (for example, a vconfig command) sent to the first target server by the user.
It should be noted that, after the first VLAN and the second VLAN are constructed, a data transmission path belonging to the first VLAN and a data transmission path belonging to the second VLAN can be established, and an IP network segment to which a physical network card of the first target server belongs is different from an IP network segment to which a virtual network card belongs, so that isolation can be formed between data transmitted based on the first VLAN and data transmitted based on the second VLAN, interference between data transmitted based on the first VLAN and the second VLAN is not generated, and accuracy of data transmission is further ensured.
For example, after the first VLAN and the second VLAN are constructed, it is assumed that in the first VLAN, an IP network segment where a physical network card of the first target server is located is 192.168.0.0/24 network segment, and in the second VLAN, an IP network segment where a virtual network card of the first target server is located is 192.168.1.0/24 network segment, and IP network segments of the two are different from each other.
And step 304, the first target server receives the internet protocol IP address redistributed by the second server, wherein the redistributed IP address is distributed for the virtual network card and/or the physical network card by the second server based on DHCP when the IP address of the virtual network card is determined to be the same as the IP address of the physical network card by the second server.
After the first VLAN and the second VLAN are constructed, if the network is maintained or modified, the IP address of the physical network card in the first VLAN and the IP address of the virtual network card in the second VLAN may change, which may cause the changed IP address of the virtual network card to be the same as the changed IP address of the physical network card (i.e., the IP addresses of the two conflict with each other), and at this time, if data transmission is performed based on the virtual network card and/or the physical network card, a transmission error may occur in the transmitted management data and service data.
For this situation, when the second server determines that the IP address of the virtual network card is the same as the IP address of the physical network card, the second server may reallocate the IP address for the virtual network card and/or the physical network card based on a Dynamic Host Configuration Protocol (DHCP), so as to ensure that the IP network segment to which the virtual network card belongs is different from the IP network segment to which the physical network card belongs, thereby ensuring the accuracy of data transmission.
The DHCP is a network Protocol of a local area network, and operates based on a User Datagram Protocol (UDP), and the DPCH is mainly used for: an IP address is automatically assigned to an internal network or network service provider of the local area network, and a right to manage all computers is assigned to a user of the local area network or an internal network administrator.
For example, it is assumed that an IP network segment to which a virtual network card belongs is different from an IP network segment to which a physical network card belongs by default in a certain data transmission system, and the IP network segment to which the virtual network card belongs is 192.168.1.0/24, and in a certain network modification, the IP network segment to which the physical network card belongs is modified to be 192.168.1.0/24, which causes a conflict between the IP network segment of the physical network card and the IP network segment of the virtual network card, at this time, the second server may reallocate an IP address for the physical network card based on DHCP, and the first target server may ensure that the IP network segment to which the virtual network card belongs is different from the IP network segment to which the physical network card belongs after receiving the IP address reallocated for the physical network card by the second server.
It should be noted that, when the second server reallocates the IP network segments to the plurality of first servers in the data transmission system, the second server may modify only the IP of the network managed by the second server, that is, may modify the IP network segments to which the virtual network cards of the plurality of first servers belong, that is, may reallocate the IP network segments of the virtual network cards.
And 305, when the data to be sent is second data, the first target server sends the second data to the second server through the second VLAN.
The second data may be management data, and the management data is used for the second server to manage the first target server.
Optionally, referring to fig. 4, the implementation process of this step 305 may include:
3051, the first target server sends the second data to the physical network card through the virtual network card.
3052, the first target server sends the second data to the second server through the internet access of the physical network card based on the second VLAN.
Referring to fig. 5, it is assumed that the data transmission system includes a second server and two first servers, the two servers are a first target server and another first server, respectively, an IP address of a physical network card eth0 of the first target server is 192.168.0.1, and based on a virtual network card eth0 configured in a physical network card eth0 of the first target server: the IP address of the VLAN 100 is 192.168.1.1, the IP address of the physical network card eth0 of the another first server is 192.168.0.2, and the virtual network card eth0 configured based on the physical network card eth0 of the another first server: the IP address of the VLAN 100 is 192.168.1.2, the IP address of the physical network card eth0 of the second server is 192.168.0.3, and based on the virtual network card eth0 configured by the physical network card eth0 in the second server: the IP address of the VLAN 100 is 192.168.1.3, and a first VLAN is constructed based on the physical network card eth0 of the first target server, the physical network card eth0 of the another first server, and the physical network card eth0 of the second server, and based on the virtual network card eth0 of the first target server: VLAN 100, virtual network card eth0 of the other first server: VLAN 100 and virtual network card eth0 of the second server: VLAN 100 constructs a second VLAN, and when the first target server sends the second data to the second server, the first target server may first send the second data through a virtual network card eth 0: VLAN 100 sends the second data to the second server through the portal of physical network card eth0 based on the second VLAN, which is sent to physical network card eth0, and the data transmission path refers to the path shown by the solid line in the figure.
The first data is service data, and the service data is used for the first target server to realize communication service with other first servers.
Optionally, referring to fig. 6, the implementation process of this step 306 may include:
Referring to fig. 5, when the first target server sends the first data to the other first server, the first data may be sent to the physical network card eth0 of the first target server, and based on the first VLAN, the first data is sent to the other first server through the portal of the physical network card eth0 of the first target server, and the data transmission path refers to the path shown by the dotted line in the figure.
When the data transmission method provided by the embodiment of the invention is used for data transmission, because the paths of the first data and the second data for data transmission are different and the data to be transmitted can only be transmitted in the corresponding transmission paths, the transmitted first data and the transmitted second data cannot interfere with each other, and the first data and the second data can be separately transmitted.
In practical applications, the management data may be transmitted through a second VLAN constructed based on the virtual network card, and the service data may be transmitted through a first VLAN constructed based on the physical network card, or the service data may be transmitted through the second VLAN and the management data may be transmitted through the first VLAN. In fig. 2 and fig. 3, the data transmission method provided in the embodiment of the present invention is described by taking only the case where the management data is transmitted through the second VLAN and the service data is transmitted through the first VLAN, and when the service data is transmitted through the second VLAN and the management data is transmitted through the first VLAN, the implementation manner thereof may refer to the implementation manner shown in fig. 2 or fig. 3, which is not described again here.
Moreover, in practical applications, the frequency and the data volume of the service data to be transmitted are large, so that the management data is generally transmitted through the second VLAN, and the service data is transmitted through the first VLAN, so as to ensure the bandwidth of the transmitted service data, thereby ensuring the effective transmission of the data.
