All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following are detailed below.
The system architecture of the present solution is described first. Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture of a bare metal server and cloud host network interworking method provided in an embodiment of the present disclosure. As shown in fig. 1, the system architecture may include one or more bare metal servers 101 (a plurality of servers may form a server cluster), one or more cloud hosts 102, and one or more switches 103/104, where the bare metal server 101 and the cloud host 102 may belong to the same VXLAN network, or the bare metal server 101 belongs to the VXLAN network, and the cloud host 102 belongs to the VLAN network, and in both cases, the bare metal server 101 and the cloud host 102 may communicate with each other through the switches 103/104. Wherein: the bare metal server 101 and the cloud host 102 establish communication with the corresponding switches 103/104, respectively, and the switches 103/104 can establish communication with the bare metal server 101 and the cloud host 102 at the same time. In practice, the bare metal server 101 is connected to the switch 103/104 through a physical port, data exchange is performed with the switch 103/104 directly through the physical port, and the cloud host 102 is connected to the switch 103/104 through a host server. A communication channel called a VXLAN tunnel is also established between the switches, and data frames sent by the bare metal server 101 and the cloud host 102 are sent to the other party through the VXLAN tunnel.
It should be noted that the system architecture of the bare metal server and cloud host network interworking method provided by the present application is not limited to that shown in fig. 1.
Based on the system architecture of the network interworking method between the bare metal server and the cloud host shown in fig. 1, a method for network interworking between the bare metal server and the cloud host is provided below, a flow chart of data interaction between the bare metal server and the cloud host through a switch is shown in fig. 2, and the specific steps of the network interworking method between the bare metal server and the cloud host are as follows.
In a specific embodiment, the bare metal server is connected to a switch through an access port, and the switch receives a data frame sent by the bare metal server through the access port. The data frame may be an Ethernet MAC frame, and there are two common Ethernet MAC frames, namely, the second generation Ethernet (Ethernet II) standard and the 802.3 standard of the Institute of Electrical and Electronics Engineers (IEEE).
The Ethernet MAC frame formats of the second generation Ethernet II standard and the 802.3 standard of IEEE are respectively shown in fig. 3 and 4. According to two Ethernet MAC frame formats, the frame formats of Ethernet II and IEEE802.3 are similar, the two Ethernet MAC frames both comprise a preamble, a start delimiter, a destination MAC address, a source MAC address, data and a frame check sequence, the main difference is that 2 bytes between the source MAC address and the data defined by the former are in a packet type, and the length defined by the latter is 2 bytes, the effective length value defined by the latter is different from the effective type value defined by the former, if the value is more than 1500 (0 x05 DC), the Ethernet type field is used for indicating the Ethernet II frame format, and if the value is less than or equal to 1500, the length field is used for indicating the IEEE802.3 frame format.
Specifically, since the bare metal server is connected (e.g., electrically connected) to the first port of the first switch, when the bare metal server sends the first data frame, the first switch receives the first data frame through the first port.
Specifically, a first port is set in advance by a first switch, the first port is set to be used for connecting a bare metal server, the bare metal server belongs to a VXLAN network of a tenant, and the first switch stores a corresponding relationship between the first port and a VNI of a virtual extensible local area network VXLAN network to which the bare metal server belongs. After the first switch receives the first data frame through the first port, the first switch may determine, according to the first port, a virtual extensible local area network identity VNI corresponding to the first port.
The table 1 may be referred to for a corresponding relationship between a port in the first switch and a VNI of a virtual extensible local area network VXLAN network, where VNI1 is a network identifier of a VXLAN to which the bare metal server belongs, and VNI2, VNI3, and VNI4 are network identifiers of other VXLAN networks, respectively, and the first switch receives the first data frame through the first port, and then referring to the table 1, it may be determined that the network identifier VNI is VNI1 according to the first port, that is, the network identifier of the VXLAN to which the bare metal server belongs may be determined.
Table 1 correspondence of ports and VNIs in first switch
| Port(s) | Network identification VNI |
| First port | VNI1 |
| Second port | VNI2 |
| Third port | VNI3 |
| Fourth port | VNI4 |
And 104, the first switch decapsulates the first data frame to obtain a destination MAC address in the first data frame.
Specifically, after the first switch receives the first data frame, the first switch decapsulates the first data frame to obtain a destination MAC address included in the first data frame, where the destination MAC address is a MAC address of the cloud host.
And 105, the first switch sends the first data frame to a second switch.
Specifically, after the first switch determines the network identifier VNI corresponding to the first port and the destination MAC address included in the first data frame, the MAC address of the destination switch is obtained by looking up an address mapping table. Optionally, the address mapping table stored in the first switch may refer to table 2, and if the network identifier VNI corresponding to the first port is VNI1 and the destination MAC address in the first data frame is MAC2, the MAC address MAC4 of the destination switch may be found in the mapping table according to VNI1 and MAC 2.
Table 2 address mapping table in first switch
And 106, the second switch receives the first data frame.
And step 107, the second switch decapsulates the first data frame to obtain the destination MAC address therein.
Specifically, after receiving the first data frame, the second switch decapsulates the first data frame to obtain a destination MAC address included in the first data frame, where the destination MAC address is a MAC address of the cloud host.
And step 108, the second switch sends the first data frame to the cloud host according to the destination MAC address.
Specifically, since the destination MAC address is the MAC address of the cloud host, the second switch encapsulates the first data frame after obtaining the destination MAC address, and then sends the encapsulated first data frame to the cloud host according to the destination MAC address.
In an optional scheme, the embodiment of the present application further includes steps 109 to 116, and a sequence of steps 109 to 116 and steps S101 to S108 is not limited herein, where steps 109 to 116 are described as follows:
and step 109, the cloud host sends the second data frame to the second switch.
Specifically, the cloud host communicates with the second switch through its host server, and the host server and the second switch are connected through an interface of the switch. The cloud host sends the second data frame to the host server of the cloud host, the host server encapsulates the VNI of the VXLAN network of the tenant to which the cloud host belongs in the second data frame, and then the host server sends the second data frame encapsulating the VNI of the VXLAN network of the tenant to which the cloud host belongs to the second switch.
And step 110, the second switch decapsulates the second data frame to obtain the VNI and the destination MAC address of the second data frame.
Specifically, the destination MAC address is the MAC address of the bare metal server.
In another possible implementation manner, the cloud host belongs to a virtual local area network VLAN network, and then after the cloud host sends the second data frame to the host server, the host server encapsulates a virtual local area network TAG VLAN TAG of the VLAN network to which the cloud host belongs into the second data frame instead of encapsulating the VNI of the VXLAN network of the tenant into the second data frame, and when the host server sends the second data frame in which the VLAN TAG is encapsulated into the second data frame, the second switch may determine, according to a pre-configured mapping relationship between the VLAN TAG and the VXLAN VNI, the VXLAN VNI corresponding to the VLAN TAG in the second data frame, where the VXLAN VNI is the same as the VXLAN VNI of the VXLAN network to which the bare metal server belongs. That is, in this implementation, the second switch may also obtain the VNI and the destination MAC address from the second data frame.
And step 111, the second switch determines the destination switch according to the obtained VNI and the destination MAC address in the second data frame.
Specifically, the MAC address of the destination switch is determined according to the VNI and the destination MAC address, where the destination switch is the first switch.
And step 112, the second switch sends the second data frame to the first switch.
And after determining the MAC address of the destination switch, the second switch encapsulates a second data frame, encapsulates the VNI into the second data frame, and sends the encapsulated second data frame to the destination switch according to the MAC address of the destination switch, namely to the first switch.
And step 113, the first switch receives the second data frame.
And step 114, the first switch decapsulates the second data frame to obtain a destination MAC address in the second data frame.
And step 115, the first switch sends the second data frame to the bare metal server according to the destination MAC address in the second data frame.
Specifically, after receiving the second data frame, the first switch decapsulates the second data frame to obtain a destination MAC address in the second data frame, where the destination MAC address is the MAC address of the bare metal server, encapsulates the second data frame, and sends the encapsulated second data frame to the bare metal server according to the obtained destination MAC address.
To sum up, in the present solution, a special virtualization technology is not required, the bare metal server is connected to the switch, and a corresponding relationship between a port on the switch for connecting the bare metal server and a network identifier VNI of the VXLAN network to which the bare metal server belongs is configured, so that the switch can send a data frame from the bare metal server to the VXLAN network according to the corresponding relationship between the port and the VNI, thereby implementing communication between the bare metal server and a cloud host in the VXLAN network.
In order to better understand the method of the present embodiment, fig. 5 shows a schematic flowchart of the interworking between the bare metal server and the cloud host.
Referring to fig. 5, the MAC addresses of the bare metal server, the cloud host, the first switch, and the second switch are MAC1, MAC2, MAC3, and MAC4, respectively. The bare metal server sends a first data frame to the first switch, and the first data frame comprises a source MAC address, namely an MAC address MAC1 of the bare metal server, and a destination MAC address, namely an MAC address MAC2 of the cloud host; the method comprises the steps that a first switch receives a first data frame through a first port, a network identifier VNI1 is determined according to the corresponding relation between the port and the network identifier of a network to which a bare metal server belongs, the first data frame is de-encapsulated to obtain a destination MAC address MAC2, the MAC address MAC4 of the destination switch, namely a second switch, is obtained according to an address mapping table, the VNI1 is encapsulated into the first data frame, and the first data frame carrying VNI1 information is sent to the second switch; the second switch receives the first data frame sent by the first switch, decapsulates the first data frame, obtains a destination MAC address in the first data frame, namely the MAC address MAC2 of the cloud host, and then sends the first data frame to the cloud host according to the MAC 2.
On the other hand, the cloud host sends a second data frame carrying the source MAC address MAC2 and the destination MAC address MAC1 to the host server, the host server marks a VLAN TAG on the second data frame and then sends the second data frame carrying the VLAN TAG to the second switch, the second switch de-encapsulates the second data frame to obtain the VLAN TAG and the destination MAC address MAC1, finds the VNI1 of the VXLAN network to which the cloud host belongs in the mapping table according to the VLAN TAG, determines the MAC address MAC3 of the destination switch, namely the MAC address MAC3 of the first switch according to the VNI and the MAC1, encapsulates the VNI into the second data frame, and sends the encapsulated second data frame to the first switch; and the first switch receives the second data frame sent by the second switch, decapsulates the second data frame, obtains a destination MAC address in the second data frame, namely the MAC address MAC1 of the bare metal server, and then sends the second data frame to the bare metal server according to the MAC 1.
To sum up, in the present solution, a special virtualization technology is not required, the bare metal server is connected to the switch, and a corresponding relationship between a port on the switch, which is used for connecting the bare metal server, and a network identifier VNI of a VXLAN network to which the bare metal server belongs is configured, so that the switch can send a data frame from the bare metal server to the VXLAN network according to the corresponding relationship between the port and the VNI, thereby implementing communication between the bare metal server and a cloud host in the VXLAN network.
As an alternative, the mutual communication between the bare metal server and the cloud host in the same VXLAN network may also be achieved through a switch, and the system architecture is shown in fig. 6, where the system architecture may include one or more bare metal servers 101 (multiple servers may form a server cluster), one or more cloud hosts 102, and a switch 103, where the bare metal server 101 and the cloud host 102 belong to the same VXLAN network, and the two are communicated with each other through the switch 103. Wherein: the bare metal server 101 and the cloud host 102 establish communication with the switch 103, respectively. Actually, the bare metal server 101 is connected to the switch 103 through a physical port, and directly performs data exchange with the switch 103 through the physical port, the cloud host 102 is connected to the switch 103 through the host server, and the cloud host 102 first sends the data information to the host server, and the data information is forwarded to the switch 103 by the host server.
Based on the system architecture shown in fig. 6, a data interaction flow chart for implementing the interworking between the bare metal server and the cloud host may also be shown in fig. 7. The scheme shown in fig. 7 may include the following steps:
step 701, the bare metal server sends a first data frame to the switch.
Step 702, the switch receives the first data frame through a first port.
Step 703, the switch determines a virtual extensible local area network identifier VNI corresponding to the first port.
Step 704, the switch decapsulates the first data frame to obtain a destination MAC address in the first data frame.
Step 705, the switch sends the first data frame to a cloud host.
Specifically, after the switch determines the VNI corresponding to the first port and obtains the destination MAC address in the first data frame, a server receiving the first data frame may be determined according to the VNI and the destination MAC address, where the server receiving the first data frame is the cloud host, and therefore, the switch sends the first data frame to the cloud host.
Step 706, the cloud host sends a second data frame to the switch.
Step 707, the switch receives the second data frame.
Step 708, the switch decapsulates the second data frame, and obtains the VNI and the destination MAC address of the second data frame.
And 709, the switch sends the second data frame to the bare metal server.
Specifically, after the switch obtains the VNI and the destination MAC address of the second data frame, the server that receives the second data frame may be determined according to the VNI and the destination MAC address, where the server that receives the first data frame is the bare metal server, and therefore, the switch sends the second data frame to the bare metal server.
In addition, the specific implementation of each operation described in fig. 7 may correspond to the corresponding description of the scheme shown in fig. 2, and is not described again here.
To sum up, in the present solution, a special virtualization technology is not required, the bare metal server is connected to the switch, and a corresponding relationship between a port on the switch for connecting the bare metal server and a network identifier VNI of the VXLAN network to which the bare metal server belongs is configured, so that the switch can send a data frame from the bare metal server to the VXLAN network according to the corresponding relationship between the port and the VNI, thereby implementing communication between the bare metal server and a cloud host in the VXLAN network.
