Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for packet transmission, and a machine-readable storage medium.
Background
VXLAN (Virtual eXtensible Local Area Network) is a two-layer VPN (Virtual Private Network) technology based on IP Network and adopting a "MAC (Media Access Control) in UDP (User Datagram Protocol)" encapsulation form. VXLAN can provide two-layer interconnection for decentralized sites based on existing service provider or enterprise IP networks and can provide service isolation for different tenants.
In VXLAN, the message is usually transmitted based on the destination MAC address of the message, for example, VTEP (VXLAN Tunnel End Point) learns the MAC forwarding table, and after receiving the message with the destination MAC address MAC1, the message is forwarded through the interface a, and after receiving the message with the destination MAC address MAC2, the message is forwarded through VXLAN Tunnel 1.
TABLE 1
| MAC address | Outlet interface |
| MAC1 | Interface A |
| MAC2 | VXLAN tunnel 1 |
However, when there are a large number of hosts, because the specification of the MAC forwarding table is limited, if the storage space of the MAC forwarding table is already occupied, the MAC forwarding table entries of all the hosts cannot be stored, and then the message transmission is abnormal. Moreover, if MAC addresses of different hosts collide, message transmission is also abnormal.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. Depending on the context, moreover, the word "if" is used may be interpreted as "at … …," or "when … …," or "in response to a determination.
The embodiment of the present disclosure provides a message transmission method, which may be applied to a VXLAN, where the VXLAN may include a plurality of edge devices, and the edge devices are connected to a host. Referring to fig. 1A, a schematic view of an application scenario of the embodiment of the present disclosure is shown, taking an example that an edge device is a VTEP device. VTEP111 is connected to host 101 via interface 111, VTEP111 is connected to host 104 via interface 114, VTEP112 is connected to host 102 via interface 112, and VTEP113 is connected to host 103 via interface 113. A VXLAN tunnel 1 is established between VTEP111 and VTEP112, a VXLAN tunnel 2 is established between VTEP111 and VTEP113, and a VXLAN tunnel 3 is established between VTEP112 and VTEP 113. The establishment mode for the VXLAN tunnel may be manual establishment or automatic establishment based on a protocol, which is not described in detail herein.
In fig. 1A, each interface of the VTEP device is taken as an example to be connected with only one host, in practical applications, one interface of the VTEP device may also be connected with multiple hosts, as shown in fig. 1B, VTEP111 is connected to the access stratum switch through interface 111, and the access stratum switch is connected with multiple hosts (in the figure, host 101 and host 105 are taken as an example), VTEP113 is connected to the access stratum switch through interface 113, and the access stratum switch is connected with multiple hosts (in the figure, host 103 and host 106 are taken as an example). When the interface of the VTEP device is connected to a plurality of hosts, the processing flow is similar to that of the VTEP device when the interface is connected to one host, and for convenience of description, the application scenario shown in fig. 1A is described as an example.
For the message transmission between two hosts (hereinafter referred to as a first host and a second host), in the conventional manner, the message transmission is implemented based on the MAC address, but in the embodiment of the present disclosure, the message transmission between the first host and the second host may be implemented by a specific tag without relying on the learning and forwarding of the MAC address.
In an example, the application scenario of the message transmission method may be as follows: a host (e.g., one or more hosts, which will be referred to hereinafter as a first host) under a certain interface (which will be referred to hereinafter as a first interface) of a VTEP device (which will be referred to hereinafter as a first device) accesses only a host (e.g., one or more hosts, which will be referred to hereinafter as a second host) under a certain interface (which will be referred to hereinafter as a second interface) of another VTEP device (which will be referred to hereinafter as a second device). Moreover, the second host under the second interface of the second device only accesses the first host under the first interface of the first device. For example, a host under interface 111 of VTEP111 (e.g., host 101 in fig. 1A, or host 101 and host 105 in fig. 1B) only accesses a host under interface 112 of VTEP112 (e.g., host 102 in fig. 1A or 1B). Furthermore, hosts under interface 112 of VTEP112 only access hosts under interface 111 of VTEP 111.
In one example, to implement the transmission of the message, a specific flag may be configured for a first interface of the first device, and the same specific flag may be configured for a second interface of the second device. For example, when there is a message transmission requirement between the host under the interface 111 and the host under the interface 112, the corresponding relationship between the specific tag a and the interface 111 may be configured in the VTEP111, and the corresponding relationship between the specific tag a and the interface 112 may be configured in the VTEP 112. For another example, when there is a message transmission requirement between the host under the interface 113 and the host under the interface 114, the corresponding relationship between the specific flag B and the interface 114 may be configured in the VTEP111, and the corresponding relationship between the specific flag B and the interface 113 may be configured in the VTEP 113.
To implement the above process, a controller, such as an SDN (Software Defined Network) controller, may be further included in the VXLAN, and the controller may be connected to each VTEP device. In fig. 1A, neither the controller nor the connection relationship of the controller to the VTEP apparatus is shown.
Based on this, when the controller learns that the first interface of the first device and the second interface of the second device have a message transmission requirement, a specific mark can be set for the first interface and the second interface. Then, the controller may send a configuration command to the first device, where the configuration command carries a corresponding relationship between the specific mark and the first interface, and the first device may establish the corresponding relationship between the specific mark and the first interface after receiving the configuration command. In addition, the controller may send a configuration command to the second device, where the configuration command carries a corresponding relationship between the specific mark and the second interface, and the second device may establish the corresponding relationship between the specific mark and the second interface after receiving the configuration command.
For example, when there is a message transmission requirement between the host under the interface 111 and the host under the interface 112, the controller sets a specific flag a for the interface 111 and the interface 112. Then, the controller sends a configuration command to the VTEP111, where the configuration command carries a corresponding relationship between the specific tag a and the interface 111, and the VTEP111 establishes the corresponding relationship between the specific tag a and the interface 111 after receiving the configuration command. The controller sends a configuration command to the VTEP112, where the configuration command carries a corresponding relationship between the specific tag a and the interface 112, and after receiving the configuration command, the VTEP112 establishes a corresponding relationship between the specific tag a and the interface 112.
For another example, when there is a message transmission requirement between the host under the interface 113 and the host under the interface 114, the controller sets a specific flag a for the interface 113 and the interface 114. Then, the controller sends a configuration command to the VTEP111, where the configuration command carries a corresponding relationship between the specific tag B and the interface 114, and after receiving the configuration command, the VTEP111 establishes a corresponding relationship between the specific tag B and the interface 114. The controller sends a configuration command to VTEP113, where the configuration command carries a corresponding relationship between the specific mark B and the interface 113, and after receiving the configuration command, VTEP113 establishes a corresponding relationship between the specific mark B and the interface 113.
In the above process, a process of configuring the specific mark for the interface by the controller is described in detail, in practical applications, in order to implement message transmission, the configuration is not limited to configuring the specific mark for the interface, for example, the controller may configure the specific mark for the specific attribute, as long as a unique interface can be found through the specific attribute. The specific attribute may include, but is not limited to, user information, aggregation member information, data center information, and the like.
For example, the controller may associate a specific flag a with the interface 111 and the interface 112 by configuring the specific flag a for the specific attribute a, having a correspondence between the specific attribute a and the interface 111 on the VTEP111, and having a correspondence between the specific attribute a and the interface 112 on the VTEP 112.
In summary, in the embodiment of the present application, a process of configuring a specific mark for a controller is not limited, and the controller is a process of configuring a specific mark for an interface, which is only an example of the present application and is not described herein again.
In one example, since the message is transmitted through the VXLAN tunnel when the message is transmitted between the first device and the second device, in order to implement the message transmission by using the specific tag, a corresponding relationship between the specific tag and the VXLAN tunnel may be established. Moreover, the first device can actively send a negotiation request message to establish a corresponding relationship between the specific mark and the VXLAN tunnel in the first device/the second device; the second device may also send a negotiation request message actively to establish a correspondence between the specific tag and the VXLAN tunnel in the first device/second device. For convenience of description, the following takes the example that the first device actively sends the negotiation request message.
In one example, the process of establishing a correspondence between a specific tag and a VXLAN tunnel for the "first device/second device" may include, but is not limited to, the following: the first device may send a negotiation request message to the second device through a VXLAN tunnel between the first device and the second device, where the negotiation request message may carry a specific tag. After receiving the negotiation request message through the VXLAN tunnel, the second device firstly inquires whether a second interface corresponding to the specific mark is configured locally; if not, the process may end; if so, the second device may establish a corresponding relationship between the specific tag and the VXLAN tunnel, and send a negotiation success message to the first device through the VXLAN tunnel, where the negotiation success message may carry the specific tag. Further, after receiving the negotiation success message through the VXLAN tunnel, the first device may establish a corresponding relationship between the specific tag and the VXLAN tunnel.
For example, VTEP111 may send a negotiation request message carrying a specific tag a through each VXLAN tunnel, for example, send a negotiation request message carrying a specific tag a to VTEP112 through VXLAN tunnel 1, and send a negotiation request message carrying a specific tag a to VTEP113 through VXLAN tunnel 2. After receiving the negotiation request message, VTEP113 ends the flow because the second interface corresponding to specific flag a is not locally configured. After receiving the negotiation request message through the VXLAN tunnel 1, the VTEP112 establishes a correspondence between the specific tag a and the VXLAN tunnel 1 because the interface 112 corresponding to the specific tag a is locally configured, and sends a negotiation success message carrying the specific tag a to the VTEP111 through the VXLAN tunnel 1. After receiving the negotiation success message through VXLAN tunnel 1, VTEP111 may establish a corresponding relationship between specific tag a and VXLAN tunnel 1.
In a similar manner as described above, VTEP111 may establish a correspondence of specific tag B with VXLAN tunnel 2, and VTEP113 may establish a correspondence of specific tag B with VXLAN tunnel 2.
The types of the negotiation request message and the negotiation success message may be selected according to actual needs, for example, the negotiation request message and the negotiation success message may be based on MP-BGP (multi Protocol-Border Gateway Protocol), and the types of the messages are not limited.
In an example, the specific mark may be a Virtual Local Area Network (VLAN) identifier, a corresponding relationship between a VLAN identifier and a VXLAN identifier, or other contents, such as a specific mark a and a specific mark B, where a type of the specific mark is not limited.
In the application scenario, referring to fig. 2, a flowchart of the message transmission method is shown.
The first device establishes the corresponding relationship between the specific mark and the first interface, so that the first device can obtain the specific mark corresponding to the first interface by querying the corresponding relationship through the first interface receiving the message, and determines the specific mark corresponding to the first interface as the specific mark corresponding to the message. Of course, the first device may also determine the specific tag corresponding to the packet in other manners, for example, the first device directly parses the specific tag (such as a VLAN identifier) from the packet, which is not limited to this.
For example, after receiving a message sent by the host 101 through the interface 111, the VTEP111 may query the correspondence relationship through the interface 111, so as to obtain the specific tag a corresponding to the interface 111. For another example, after receiving the message sent by the host 104 through the interface 114, the VTEP111 may query the correspondence relationship through the interface 114, so as to obtain the specific label B corresponding to the interface 114.
At step 202, the first device determines the VXLAN tunnel corresponding to the particular tag. Since the first device already establishes the corresponding relationship between the specific mark and the VXLAN tunnel, the VXLAN tunnel corresponding to the specific mark can be determined by querying the corresponding relationship through the specific mark.
For example, since VTEP111 already establishes the correspondence between the specific marker a and the VXLAN tunnel 1 and the correspondence between the specific marker B and the VXLAN tunnel 2, if the specific marker a is obtained in step 201, the VXLAN tunnel 1 corresponding to the specific marker a can be identified, and if the specific marker B is obtained in step 201, the VXLAN tunnel 2 corresponding to the specific marker B can be identified.
In step 205, the second device parses the specific tag from the packet, and determines a second interface corresponding to the specific tag.
Since the second device has already established the corresponding relationship between the specific tag and the second interface, the second device can determine the second interface corresponding to the specific tag by querying the corresponding relationship through the specific tag carried in the packet. Of course, the second device may also determine the second interface corresponding to the specific mark in other manners, which is not limited to this.
For example, after receiving a message carrying a specific tag a through VXLAN tunnel 1, VTEP112 parses the specific tag a from the message. Since VTEP112 has established a correspondence relationship between a specific token a and an interface 112, it is determined that the second interface corresponding to the specific token a is the interface 112.
For another example, after receiving a message carrying the specific tag B through the VXLAN tunnel 2, the VTEP113 parses the specific tag B from the message. Since VTEP113 has already established a correspondence relationship between specific flag B and interface 113, it is determined that the second interface corresponding to the specific flag B is interface 113.
For example, VTEP112 sends a message to host 102 through interface 112, and by this time, successfully sends a message from host 101 to host 102, in the process, the message transmission is completed through specific tag a.
For another example, VTEP113 sends a message to host 103 through interface 113, and thus, successfully sends a message from host 104 to host 103, and in the process, the message transmission is completed through specific tag B.
In the above process, a flow of sending a message from the first host to the second host is described in detail, and similar to the above process, the process of sending a message from the second host to the first host is not repeated here.
Aiming at the process that the first equipment sends the message to the second equipment through the VXLAN tunnel, the first equipment can encapsulate a VXLAN head, a UDP head and an IP head corresponding to the VXLAN tunnel for the message and send the encapsulated message to the second equipment, and the second equipment firstly de-encapsulates the message after receiving the message and processes the de-encapsulated message, and the encapsulation process and the de-encapsulation process are not limited.
Aiming at the process that the second equipment sends the message to the first equipment through the VXLAN tunnel, the second equipment can encapsulate a VXLAN head, a UDP head and an IP head corresponding to the VXLAN tunnel for the message and send the encapsulated message to the first equipment, and the first equipment firstly de-encapsulates the message by VXLAN after receiving the message and processes the de-encapsulated message, and the encapsulation process and the de-encapsulation process are not limited.
Based on the technical scheme, in the embodiment of the disclosure, the message transmission can be realized through the specific mark without depending on the learning and forwarding of the MAC address, so that the table lookup forwarding pressure of the device is greatly reduced, the possibility of message transmission errors is reduced, and the problem of message transmission abnormity caused by the conditions that the storage space of the MAC forwarding table is occupied, the MAC addresses of different hosts conflict and the like is avoided.
In practical applications, if the VTEP device is not directly connected to the host but connected to the host through the access layer switch, an interface where the VTEP device is connected to the access layer switch is determined as an interface where the VTEP device is connected to the host. Referring to fig. 3A, which is a schematic diagram of an application scenario of the embodiment of the present disclosure, the VTEP112 is connected to the access stratum switch through the interface 112, and the access stratum switch is connected to the host 102.
In this application scenario, for the data transmission process, the same as the flow shown in fig. 2 is performed, except that after the VTEP112 sends the packet to the access layer switch through the interface 112, the access layer switch does not transmit the packet based on the specific tag a, but transmits the packet based on the destination MAC address of the packet, and details of the transmission process are not repeated.
In the above application scenario, the first device and the second device are both VTEP devices as an example, however, the application scenario of the present application is not limited to VTEP devices, and the first device and the second device may also be other types of devices, and the application scenario is not limited thereto. For example, as shown in fig. 3B, when the host under the interface a has a communication requirement with the host under the interface B, the first device may also be a convergence layer switch, and the second device may be a data center access switch, and the first interface is the interface a and the second interface is the interface B, in this application scenario, the above technical solution may also be adopted for processing.
Specifically, a VXLAN tunnel may be established between the convergence layer switch and the data center access switch, and the convergence layer switch may establish a corresponding relationship between the specific tag and the VXLAN tunnel and a corresponding relationship between the specific tag and the interface a, and the data center access switch may also establish a corresponding relationship between the specific tag and the VXLAN tunnel and a corresponding relationship between the specific tag and the interface B.
Based on this, after receiving the message through the interface a, the convergence layer switch may query the specific tag, and send the message to the data center access switch through the VXLAN tunnel corresponding to the specific tag. Then, after receiving the message, the data center access switch may send the message through the interface B corresponding to the specific tag carried in the message, and the processing flow is similar to that in the above embodiment, and is not described herein again.
Obviously, the above manner is to send the message to the data center access switch based on a specific label, rather than sending the message to the data center access switch based on the MAC address. Therefore, the message can be sent to the data center access switch without depending on the learning and forwarding of the MAC address, so that the table lookup forwarding pressure of the convergence layer switch is greatly reduced, the possibility of message transmission errors is reduced, and the problem of message transmission abnormity caused by the conditions that the storage space of an MAC forwarding table is occupied, the MAC addresses of different hosts conflict and the like is avoided.
