Fig. 1 shows a flowchart of a method for implementing inter-virtual machine communication according to an aspect of the present application, where the method includes: step S11 to step S14,
in step S11, an agent on the same host as the virtual machine captures optimized message information sent by a master agent to the virtual machine; here, the master Agent is a router network Agent, and may send a control command to the virtual machine, and a network Agent (computer node network Agent) located on a physical machine where the virtual machine is located captures the control command, and the computer node network Agent replies a message to the router network Agent. In an SDN network, cloud routing is distributed routing. And the main agent sends the optimized message information to the virtual machine, and the agent positioned on the same host machine on the virtual machine captures the optimized message information.
Next, in step S12, a routing bridge for connecting the first vlan interface bridge and the second vlan interface bridge is created based on the optimized packet information, where the virtual machines include a first virtual machine and a second virtual machine; after capturing the optimized message information, the agent on the same host as the virtual machine creates a routing bridge connecting the first virtual machine lan interface bridge (VLAN1 bridge) and the second virtual lan interface bridge (VLAN2 bridge), wherein the first virtual lan interface bridge is the first virtual machine lan interface bridge, and the second virtual lan interface bridge is the second virtual machine lan interface bridge.
In step S13, an address translation rule and a flow guiding rule for a traffic forwarded by the routing bridge are determined, where the traffic includes a packet and packet feedback information; after the routing bridge is created, determining an address conversion rule and a diversion rule when the direct flow of the virtual machine is forwarded through the routing bridge, wherein when the first virtual machine sends a message to the second virtual machine, the flow is the message, when the second virtual machine sends message feedback information to the first virtual machine according to the received message, the flow is the message feedback information, the address conversion rule is used for modifying addresses (such as MAC addresses) of the virtual machine sending the flow and the virtual machine receiving the flow so as to facilitate the forwarding of the flow through the established routing bridge, and the diversion rule is used for introducing the flow into the routing bridge, so that the transmission of the flow between the virtual machines is realized through the routing bridge.
In step S14, communication between the virtual machines is completed according to the address translation rules and the flow guiding rules. Here, a message path between the virtual machines is established according to the determined address conversion rule and the flow guiding rule, and a message sent from the first virtual machine to the second virtual machine reaches the second virtual machine according to the message path, so that forwarding through cloud routing is avoided, matching rules and configuration are few, and the probability of errors is reduced.
Specifically, the address translation rule includes: when the first virtual machine sends a message to the second virtual machine, modifying the destination MAC address of the message from the MAC address of the routing gateway corresponding to the first virtual machine to the MAC address of the second virtual machine; when the second virtual machine sends message feedback information to the first virtual machine, modifying the destination MAC address of the message feedback information from the MAC address of the routing gateway corresponding to the second virtual machine to the MAC address of the first virtual machine. Here, when the first virtual machine (VM1) sends a message to the second virtual machine (VM2), an address translation rule is issued to modify the destination MAC address of traffic from VM1 to VM2 from the MAC address of the cloud routing gateway corresponding to the first virtual machine to the MAC address of VM 2; when the second virtual machine VM2 returns the feedback information of the message, the address conversion rule modifies the destination MAC address of the traffic from VM2 to VM1 from the MAC address of the cloud routing gateway corresponding to the second virtual machine to the MAC address of VM1, for example, the first virtual machine is located on the 10.0.1.0/24 network, the second virtual machine is located on the 10.0.2.0/24 network, when the first virtual machine sends the message to the second virtual machine, the traditional path is forwarded through the cloud routing, the cloud routing includes gateway 10.0.1.1 and gateway 10.0.2.1, where the gateway 10.0.1.1 is the destination MAC address when the first virtual machine sends the message to the second virtual machine, the gateway 10.0.2.1 is the destination MAC address when the second virtual machine returns the information to the first virtual machine, when the routing bridge is established, the destination MAC address of the traffic from the first virtual machine to the second virtual machine needs to be modified from the MAC address of the gateway 10.0.1.1 to the second virtual machine when the first virtual machine sends the subsequent message to the second virtual machine, likewise, when the second virtual machine returns information, the destination MAC address of traffic from the second virtual machine to the first virtual machine needs to be modified by the gateway 10.0.2.1 to the MAC address of the first virtual machine.
Specifically, the diversion rule includes: when the first virtual machine sends a message to the second virtual machine, the message is forwarded to the second virtual local area network interface network bridge by the first virtual local area network interface network bridge through the routing network bridge; when the second virtual machine sends message feedback information to the first virtual machine, the second virtual local area network interface bridge forwards the message feedback information to the first virtual local area network interface bridge through the routing bridge. Here, when the first virtual machine VM1 sends a packet to the second virtual machine VM2, the packet traffic needs to be directed from the VLAN1 bridge to the routing bridge, and forwarded to the VLAN2 bridge through the routing bridge. When the second virtual machine VM2 returns information to the first virtual machine VM1, the traffic of the returned information is directed from the VLAN2 bridge to the routing bridge, through which it is forwarded to the VLAN1 bridge.
In an embodiment of the present application, the optimized packet information is determined by the master agent according to the routing information of the first packet. Specifically, the method comprises the following steps: and capturing the routing information of the first message through the master agent, wherein the master agent and the first message pass through a route on the same host, and the route records the routing information of the first message in a connection tracking table. Here, the first packet is a first packet sent when communication is performed between virtual machines located in different networks, the virtual machines need to forward the first packet through a cloud route because the MAC address of the other virtual machine cannot be found when sending the first packet, the first packet is routed when forwarding the first packet through the cloud route, and a master Agent (Agent) located on the same host as the cloud route through which the first packet passes captures the routing process, so as to obtain routing information. And the cloud routing records the routing information of the first message in a connection tracking table.
In an embodiment of the present application, the routing information of the first packet includes: sending routing information of the first message and feedback routing information of the first message, wherein the sending routing information of the first message comprises channel state information which is sent to the first virtual local area network interface by the first virtual machine and is forwarded from the second virtual local area network interface to the second virtual machine by the gateway of the route; the feedback routing information of the first message comprises channel state information which is sent to the second virtual local area network interface by the second virtual machine and is transmitted from the first virtual local area network interface to the first virtual machine after being forwarded by the gateway of the route. Here, as shown in fig. 2, when the virtual machine 1 is located on the physical machine 1, the virtual machine 2 is located on the physical machine 2, the cloud route is located on the physical machine 3, and when the virtual machine 1 located on the network 10.0.1.11/24 sends a message to the virtual machine 2 located on the network 10.0.2.12/24, the path taken by the first message is from the virtual network card to the first physical network card on the physical machine 1 through the VLAN1 bridge and the VLAN subinterface in sequence, to the VLAN1 subinterface through the third physical network card on the physical machine 3, to the VLAN bridge, and to the gateway 10.0.1.1 on the cloud route, and is forwarded through the gateway 10.0.2.1 on the cloud route, to the third physical network card through the virtual network card, the VLAN2, and the VLAN subinterface in sequence, to the physical network card (the second physical network card) on the physical machine 2 on the virtual machine 2 through the third physical network card, to the virtual network card 2 through the VLAN2 subinterface, the VLAN bridge, the path forwarded by the cloud route is recorded in a connection tracking table; similarly, when the information returned from the virtual machine 2 reaches the virtual machine 1, the information is also forwarded through the cloud route, and the returned path is also recorded in the connection tracking table. The method comprises the steps that a main agent judges whether a path of flow from a virtual machine 1 to the virtual machine 2 forwarded through a cloud route is in a path state or not and whether a path of flow returned from the virtual machine 2 to the virtual machine 1 forwarded through the cloud route is in the path state or not, when the paths are in the path states, an instruction of a subsequent message walking optimization path (a second message path) can be sent to the virtual machine, and the subsequent message walking optimization path is established, wherein the optimization path is a path determined by establishing a routing bridge and a determined address conversion rule and a flow guide rule.
In an embodiment of the present application, after a routing bridge for connecting a first virtual local area network interface bridge and a second virtual local area network interface bridge is created based on optimized message information sent by a host agent to a virtual machine, the traffic is identified on the virtual local area network interface bridge sending the traffic, so as to guide the traffic to the routing bridge; matching the MAC address and the bridge interface through the routing bridge, and forwarding the flow to the virtual local area network interface bridge receiving the flow. Here, when VM1 sends a packet to VM2, VM1 is a virtual machine that sends traffic, VLAN1 bridge is a virtual lan interface bridge that sends traffic, VM2 is a virtual machine that receives traffic, VLAN2 bridge is a virtual lan interface bridge that receives traffic, and after the traffic is identified by VLAN1 bridge, the traffic is directed from VLAN1 bridge to routing bridge, which forwards the traffic to VLAN2 bridge by MAC address and port matching. Similarly, when VM2 returns information to VM1, VLAN2 bridge of VM2 is the VLAN1 bridge that sends traffic, and the return path is the MAC address and bridge interface match forwarded to VLAN1 bridge via the routing bridge.
In an embodiment of the present application, the master agent determines optimized packet information based on the routing information of the first packet and a preset trigger condition. Wherein the trigger condition comprises any one of: the path state information in the sending routing information of the first message and the path state information in the feedback routing information of the first message are both in an intercommunication state; traffic between the first virtual machine and the second virtual machine is degraded.
The route that the first message passes through is a first route, route information is determined according to the first route, the route information is further analyzed, whether the first route is normal or not is determined, if the first route is normal, a preset trigger condition is met, and a subsequent message is triggered to pass through a second message route, wherein the second message route is a route that does not pass through a router, but is used for feeding back optimized message information to a virtual machine associated with the first message through a master agent, a routing bridge is created, and forwarding is performed through the routing bridge so as to perform communication between the first virtual machine and the second virtual machine. In the embodiment described in the present application, the information of the packet is obtained in a bypass manner, which is a manner of monitoring through a proxy, and does not depend on a database, so that it is preferentially ensured that the user service is not affected in any situation. The triggering condition also comprises the condition that the flow between the first virtual machine and the second virtual machine is degraded, when the flow is degraded, the path where the message travels is reduced to a first path, and if the flow between the first virtual machine and the second virtual machine is still in an active state, the message is triggered again to travel an optimized path. And then the method can be used for optimizing active connections only, not doing unnecessary optimization actions, and only causing traffic degradation under the worst network condition without interrupting a communication link between the virtual machines. It should be noted that, when the path state information of the first packet is in the disabled state, the virtual machine is powered off or security group isolation is performed.
In an embodiment of the present application, the method includes: step S10, the master agent sends check instruction information to the virtual machine based on the routing information of the first packet; an agent on the same host as the virtual machine captures the inspection instruction information and feeds back an inspection result to the main agent according to the inspection instruction information; and the main agent sends optimized message information to the virtual machine according to the check result and a preset protocol format. The method comprises the steps that a main agent on the cloud route sends a check instruction to computing nodes to check whether each computing node is normal or not and whether a network agent on each computing node is alive or not, the network agent on each computing node captures the check instruction in an intercepting mode, the check result is replied after the check is normal or not, and when the check result is normal, the main agent sends optimized message information to a virtual machine according to a preset protocol format. The preset protocol format is based on an IP protocol, a network agent on a computing node monitors all traffic which enters the computing node and is in the preset protocol format, and a network agent on a router monitors all traffic which enters the router and is in the preset protocol format, so that the network agent on the router only needs to send a message in the preset protocol format to a virtual machine needing to optimize the traffic, and the message is intercepted and analyzed on a physical machine, so that a control instruction is sent to a correct computing node through the preset protocol format on the premise that the computing node where the virtual machine is located is not known, and the correctness is guaranteed by the operation of a network bottom layer, so that the risks of database information errors, outdating and the like are avoided. The computing nodes are hosts where a first virtual machine and a second virtual machine in the distributed network are located.
In an embodiment of the present application, with reference to fig. 2, the virtual machine 1 sends the first packet to the virtual machine 2, and first sends the first packet to the gateway 10.0.1.1 through the VLAN1, the first packet is forwarded to the VLAN2 through the cloud route so as to reach the virtual machine 2, the virtual machine 2 replies the packet through the same path, and the connection tracking table on the cloud route records the connection. The method comprises the steps that a network agent (a main agent) on a cloud route sends a check instruction to virtual machines (a virtual machine 1 and a virtual machine 2) on a computing node to check whether the network agents (the network agent 1 and the network agent 2) on the computing node are alive or not, when the network agents (the network agent 1 and the network agent 2) are alive, the main agent sends optimization message information to the virtual machine 1 and the virtual machine 2, the network agent 1 and the network agent 2 obtain the instruction of the optimization message information in an intercepting mode, therefore, the network agent 1 on the computing node where the virtual machine 1 is located can create a routing bridge, the VLAN1 and the VLAN2 bridge are connected, address conversion rules are sent, the destination MAC address of traffic from the virtual machine 1 to the VM2 is modified to the MAC address of the virtual machine 2 from the MAC of the cloud routing 10.0.1.1, flow guiding rules are sent, the traffic from the VLAN1 to the routing bridge of the virtual machine 2 is guided to the VLAN routing bridge, and then the traffic is forwarded to the VLAN 2. Similarly, the network agent 2 on the computing node where the virtual machine 2 is located creates a routing bridge and establishes a path for traffic from the virtual machine 2 to the virtual machine 1 according to the address translation rule and the flow guiding rule. The path followed by the subsequent message is the path forwarded by the routing bridge.
