Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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 application.
The embodiment of the application provides a message forwarding method, equipment and medium based on a VXLAN network, wherein the obtained service message at the access side is configured into the VXLAN network, an FDB address table is inquired in the VXLAN network, and whether the FDB address table comprises a destination MAC address of the service message is judged; when the FDB address table comprises a target MAC address, the service message is sent to a network side through a VXLAN tunnel corresponding to unicast, and forwarding of the known unicast service message is realized; when the FDB address table does not include the destination MAC address of the service packet, the service packet needs to be flooded to the multicast group member port through the VXLAN tunnel corresponding to the multicast, so as to implement flooding of the unknown unicast service packet. The method and the device solve the technical problem that the same next hop address in the prior art cannot simultaneously bear the known unicast and the unknown unicast forwarding.
The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a message forwarding method based on a VXLAN network according to an embodiment of the present application. As shown in fig. 1, a message forwarding method based on a VXLAN network provided in an embodiment of the present application mainly includes the following steps:
step 101: and acquiring the service message of the access side through the switch to configure the service message into the VXLAN network.
The embodiment of the application realizes the forwarding of the service message through the VXLAN network. After the service message sent by the access side is acquired through the switch, the server configures the service message into the VXLAN network so as to perform subsequent operation in the VXLAN network according to the service message.
It should be noted that, in the embodiment of the present application, the switch can receive the service packets from the host and the server of the local network at the same time, or can receive the service packets from the host and the server separately.
In an embodiment of the present application, after a service packet at an access side is acquired through a switch to configure the service packet in a VXLAN network, a server can create a unicast next hop address of the service packet according to a destination MAC address in the service packet, and create a unicast virtual port corresponding to the service packet at a switch end, so as to bind the unicast next hop address of the service packet and the unicast virtual port corresponding to the service packet together, so that the server can directly find out the corresponding bound unicast virtual port according to the unicast next hop address of the service packet in the VXLAN network. The server creates a VXLAN tunnel corresponding to the unicast and associates the pre-created unicast virtual port with the VXLAN tunnel corresponding to the unicast, so that the server can determine the VXLAN tunnel corresponding to the unicast associated with the unicast virtual port according to the found unicast virtual port in the VXLAN network. In the embodiment of the application, the unicast next hop address, the unicast virtual port and the VXLAN tunnel corresponding to the unicast are associated by the above method, so that a forwarding path of the known unicast service message is established.
In an embodiment of the present application, after a service packet at an access side is obtained through a switch to configure the service packet in a VXLAN network, a server determines MAC addresses corresponding to a plurality of ports of the switch respectively by accessing the plurality of ports of the switch, so that the server creates a multicast next hop address of the service packet according to the MAC address corresponding to the port of the switch, creates a multicast virtual port corresponding to the service packet at an end of the switch, and enables the server to find the bound multicast virtual port according to the multicast next hop address in the VXLAN network by binding the multicast next hop address and the multicast virtual port together. And the server also creates a VXLAN tunnel corresponding to the multicast, and associates the pre-created multicast virtual port with the VXLAN tunnel corresponding to the multicast, so that the server can determine the VXLAN tunnel corresponding to the multicast associated with the multicast virtual port according to the found multicast virtual port. According to the method, the multicast next hop address, the multicast virtual port and the VXLAN tunnel corresponding to the multicast are bound and associated, and accordingly a flooding path of the unknown unicast service message is established.
Step 102: in the VXLAN network, a pre-configured FDB address table is inquired to judge whether the FDB address table comprises the destination MAC address of the service message.
In the VXLAN network, a switch inquires whether a pre-configured FDB address table comprises a destination MAC address of a service message, thereby determining whether the forwarding of the current service message is a unicast channel or a multicast channel.
It should be noted that the server may obtain destination MAC addresses of a plurality of service packets and ports of corresponding switches according to forwarding of historical service packets, so that an FDB address table may be established according to a correspondence between the ports of the switches and the MAC addresses, so that a subsequent server may directly send a service packet to a network side through a unicast path corresponding to the port for the service packet with a known correspondence between the port and the MAC address.
Step 103: and if the destination MAC address of the service message is determined to be included in the FDB address table, the service message is sent to the network side through a VXLAN tunnel corresponding to the pre-established unicast.
If the FDB address table includes the destination MAC address of the service packet, it indicates that the server has obtained the port of the switch corresponding to the destination MAC address of the service packet, that is, it indicates that the forwarding mode of the current service packet is unicast. In this case, the server can transmit the service packet of the known unicast to the network side through the VXLAN tunnel corresponding to the unicast created in advance.
Specifically, the server can find a unicast virtual port bound to the unicast next hop address by acquiring the unicast next hop address of the service packet, and then find a VXLAN tunnel corresponding to the associated unicast through the unicast virtual port, so as to determine a unicast forwarding path corresponding to the current service packet, and encapsulate the current service packet through the VXLAN tunnel corresponding to the unicast. Meanwhile, the server also determines corresponding output interface information according to the unicast next hop address, so that the encapsulated service message is sent to the network side through the output interface by the unicast virtual port and the VXLAN tunnel corresponding to the unicast, and the forwarding of the known unicast service message is realized.
In an embodiment of the present application, when a service packet enters a VXLAN tunnel corresponding to a unicast, a server can obtain a VXLAN tunnel endpoint list in a VXLAN broadcast domain through a control plane, and then the server can copy the service packet according to the VXLAN tunnel endpoint list and send the copied service packet to a plurality of VXLAN tunnel endpoints in the VXLAN broadcast domain, thereby implementing encapsulation of the service packet. And when the service message is sent to the network side, the server also decapsulates the service message through the VXLAN tunnel corresponding to the unicast. According to the embodiment of the application, the blocking generated during message forwarding can be avoided through encapsulation and decapsulation, so that the message forwarding efficiency is improved.
Step 104: and if the destination MAC address of the service message is determined not to be included in the FDB address table, flooding the service message to a port of a multicast group member through a VXLAN tunnel corresponding to the pre-established multicast.
If the FDB address table does not include the destination MAC address of the service packet, it indicates that the server cannot obtain the correspondence between the destination MAC address of the service packet and the port of the switch, and at this time, the forwarding manner of the service packet is flooding by unknown unicast. At this time, the server floods the service message of unknown unicast to the multicast group member port through the VXLAN tunnel corresponding to the multicast created in advance, so as to realize the flooding of the service message of unknown unicast.
Specifically, the server can find a multicast virtual port bound with a multicast next hop address by acquiring the multicast next hop address of the service message; finding a VXLAN tunnel corresponding to the multicast associated with the next hop address of the multicast through the multicast virtual port so as to determine a multicast flooding path corresponding to the service message; and packaging the current service message through a VXLAN tunnel corresponding to multicast, and then flooding the packaged service message to a multicast group member port, thereby realizing the flooding of unknown unicast service messages.
In an embodiment of the present application, before the server floods the encapsulated service packet to the multicast group member port, the server may obtain a multicast group ID from a multicast table encapsulating the service packet according to a multicast next hop address of the service packet, and then determine a corresponding multicast group member port according to the multicast group ID, so as to perform subsequent operation on the service packet according to the multicast group member port.
In an embodiment of the present application, when a server encapsulates a service packet through a VXLAN tunnel corresponding to multicast, a source IP address and a destination IP address of the service packet are fixed, where the source IP address is an IP address corresponding to a service packet sending end, and the destination IP address is an IP address corresponding to a final receiving end of the service packet, so that the source IP address and the destination IP address are not changed during a multicast flooding process of the service packet. However, when forwarding service messages in different VXLAN network segments, the source MAC address and the destination MAC address of a service message change every time the service message passes through one VXLAN network segment.
For example: the host 1 needs to send a service message to the host 2, and the service message needs to pass through the switch 1 and the switch 2 in the middle, so when the host 1 sends the service message to the switch 1, the source MAC address is the MAC address of the host 1, the destination MAC address is the MAC address of the switch 1, then when the switch 1 sends the service message to the switch 2, the source MAC address is the MAC address of the switch 1, the destination MAC address is the MAC address of the switch 2, and finally when the switch 2 sends the service message to the host 2, the source MAC address is the MAC address of the switch 2, and the destination MAC address is the MAC address of the host 1. Therefore, the change of the source MAC address and the destination MAC address of the service message can be intuitively seen.
It should be noted that the embodiment of the present application is only an assumed situation for convenience of understanding, and is not limited to the number of the sending end, the receiving end, and the passing VXLAN network segments when forwarding the service packet in different VXLAN network segments.
Fig. 2 is a flowchart of another VXLAN network-based message forwarding method according to an embodiment of the present application. As shown in fig. 2, the server queries the FDB address table through a service packet pre-configured to the access side AC in the VXLAN network, and determines whether the FDB address table includes an MAC address of the service packet, that is, whether the service packet hits the FDB address table. If yes, the FDB address table is indicated to comprise the MAC address of the service message, namely the service message is determined to be forwarded by a known unicast, at the moment, the server inquires a unicast next hop address NEXTHOP to determine a unicast Virtual Port (VP) which is correspondingly bound by the unicast NEXTHOP, and then inquires a VXLAN tunnel which corresponds to the associated unicast through the unicast VP, so that the service message is encapsulated through the VXLAN tunnel which corresponds to the unicast, and the server also determines an outgoing interface which corresponds to the service message through the unicast NEXTHOP to send the encapsulated service message to a network side through the outgoing interface, thereby completing forwarding of the unicast service message. If not, the FDB address table does not include the MAC address of the service message, that is, the service message is determined to be flooding of unknown unicast, at this time, the server queries a multicast next hop address NEXTHOP to determine a multicast Virtual Port (VP) to which the multicast NEXTHOP is correspondingly bound, and then queries a VXLAN tunnel corresponding to the associated multicast through the multicast VP, thereby encapsulating the service message through the VXLAN tunnel corresponding to the multicast. And the server also queries the multicast group ID through the multicast NEXTHOP to determine the multicast group member port corresponding to the multicast group ID, so that the encapsulated service message is flooded to the multicast group member port to realize the flooding of the service message.
It should be noted that the method shown in fig. 2 is substantially the same as the method shown in fig. 1, and therefore, portions that are not described in detail in fig. 2 may specifically refer to the related description in fig. 1, and are not described herein again.
The above is the method embodiment proposed by the present application. Based on the same inventive concept, the embodiment of the present application further provides a message forwarding device based on a VXLAN network, and the structure of the message forwarding device is shown in fig. 3.

As shown in fig. 3, the apparatus includes at least one processor; and a memory communicatively coupled to the at least one processor; wherein the memory stores instructions executable by the at least one processor to cause the at least one processor to: acquiring a service message of an access side through a switch to configure the service message into a virtual extensible local area network (VXLAN); in a VXLAN network, inquiring a pre-configured FDB address table to judge whether the FDB address table comprises a destination MAC address of a service message; if the destination MAC address of the service message is determined to be included in the FDB address table, the service message is sent to a network side through a VXLAN tunnel corresponding to a pre-established unicast; and if the destination MAC address of the service message is determined not to be included in the FDB address table, flooding the service message to a port of a multicast group member through a VXLAN tunnel corresponding to the pre-established multicast.
