Problems solved by technology
For the MAC address of VM1, only one outbound port is recorded in the MAC entry, which corresponds to service processor 1 or service processor 2. Therefore, for the message sent to VM1, the hardware switch can only send the message to service processor 1 or service processor 2, but cannot send the message from server 1 to service processor 1, and send the message from server 2 to service processor 2, that is, the service processor cannot be satisfied in the prior art business processing needs

Embodiment Construction
[0046] In view of the problems in the prior art, an embodiment of the present invention provides a method for transmitting service messages to figure 2 It is a schematic diagram of the application scenario of the embodiment of the present invention. Each VM (such as VM1, VM2, VM3) accesses each server (such as server 1, server 2, server 3) through VTEP, and each server is connected to a hardware switch and belongs to the same VXLAN. The service message of server 1 needs to be load balanced in service processor 1, the service message of server 2 needs to be cleaned in service processor 2, and the service message of server 3 does not need to be processed. Such as figure 2 As shown, the IP address of server 1 is 10.0.0.3, the IP address of server 2 is 10.0.0.4, the IP address of server 3 is 10.0.0.5, the gateway IP addresses of server 1 and server 2 are 10.0.0.1, and the gateway MAC( The Media Access Control address is 0-0-1, the gateway IP address of VM1 is 10.0.0.254, the gate...

The invention discloses a method and equipment for transmitting service messages. The method includes: a hardware switch receives a first flow table delivered by an SDN controller, and after receiving an ARP request message, if the ARP request message matches the first flow table table, the ARP request message is sent to the SDN controller, and the SDN controller generates the second flow table, and sends an ARP response message with the destination MAC address as the specified MAC address to the server; the hardware switch receives the first flow table issued by the SDN controller. Second-flow table, after receiving the service message from the server, if the service message matches the second flow table, the hardware switch uses the tunnel information corresponding to the service processor to send the service message from the server to the service processor . In the embodiment of the present invention, the SDN controller can guide the traffic corresponding to the server on the hardware switch to the service processor for service processing, which can meet the service processing requirements of the service processor.
Description
Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for transmitting service messages. Background technique [0002] With the development of data center cloud computing and virtualization technology, the scale of virtual machines supported by a data center has exploded. At the same time, virtual machine migration needs to be in the same second-tier domain, and different tenants need to be logically isolated. Since traditional VLAN (Virtual Local Area Network, virtual local area network) only supports a maximum of 4096, if VLAN technology is used to divide and isolate Layer 2 domains, the scale is far from meeting the demand. Therefore, VXLAN (VirtualeXtensible Local Area Network, scalable virtual local area network) technology came into being. VXLAN has a larger identification space and can run on a three-layer IP network, making it easier to deploy and maintain. Such as figure 1 As shown, it is a...
