Background
With the rapid growth of cloud services, more and more services are loaded on a cloud computing platform. With the complexity of services, the traffic of the cloud platform also shows explosive growth. The traffic increase not only tests the carrying capacity of the cloud network, but also provides a greater challenge for traffic monitoring of the cloud network.
Currently, in a virtual network, a statistical component of traffic is implemented on OVS-vSwitch, and a OVS-vSwitch daemon is a core component of an OVS (Open vSwitch, Open virtual switch standard), which implements OVS stream-based data exchange together with a data channel kernel module. For each data packet needing flow collection, the OVS needs to copy the message from the data channel to OVS-vswitch d in a certain mode, and then the message is classified and counted by OVS-vswitch d. In the process of counting the large flow, the process of copying the data packet and transmitting the data packet from the data channel to ovs-vswitchd causes a large overhead, and the normal forwarding of the data packet is likely to be influenced by the flow collection.

With continued reference to fig. 2, a flow 200 of an embodiment of a flow information collection method of a virtual network according to the present application is shown, comprising the steps of:
In this embodiment, the virtual network is a computer network that is at least partially linked by a virtual network. Virtual network links are implemented by network virtualization, rather than involving a physical connection between two computing devices. In a Virtual network, VMs (Virtual Machine Server) can be connected to a Virtual switch, and by means of the Virtual switch, a logical Virtual ethernet interface can be provided for VMs or containers running on the Server, so as to implement offloading and forwarding of network data.
In this embodiment, the message information is a data unit exchanged and transmitted in the virtual network, and includes complete data information such as a source IP (Internet Protocol) address, a source port, a destination IP address, a destination port, a transport layer Protocol, time, and message data. In the virtual network, the message information is shunted and forwarded through the virtual switch.
The execution body (for example, the server in fig. 1) is provided with a virtual switch, and can acquire message information in the virtual network.
In this embodiment, the preset matching rule at least includes a matching field and an action field. The matching domain is used for identifying the message information corresponding to the forwarding rule, and the action domain is used for representing the instruction information executed on the matched message information.
The match field includes, but is not limited to, the following fields: virtual local area network ID (Identity document), virtual local area network priority, source IP address, destination IP address, IP protocol, source port, destination port, transport layer protocol. Action fields include, but are not limited to, the following instructions: the instruction for forwarding the meta information of the message information, the instruction for discarding the message information when the condition is satisfied, and the instruction for assigning a queue ID to the message for implementing QOS (Quality of Service).
For example, the format of the preset forwarding rule may be "source IP is 11:11:11:11/24, destination IP is 10.10.10.0/24, action is statistical flow information, and the forwarding rule is forwarded from the port 10". The preset forwarding rule is used for representing that the meta information of the message information with the source IP of 11:11:11:11/24 and the destination IP of 10.10.10.0/24 is forwarded to the aggregation module from the port 10 for flow information statistics.
In this embodiment, the execution body matches the packet information in the matching domain through the matching domain identifier of the preset matching rule, and forwards the meta information of the matched packet information to the aggregation module through the forwarding instruction in the action domain of the preset forwarding rule.
In some optional implementation manners, the execution main body forwards the meta information of the message information according to a preset export moment so as to intensively forward the meta information of the message information, and reduce the operation overhead time caused by forwarding the meta information of the message information in real time. Specifically, the execution main body stores the meta information of the message information into a cache in response to determining that the message information is matched with a matching field of a preset forwarding rule; and in response to the preset export moment, forwarding the meta information of the message information in the cache to an aggregation module specified by the forwarding instruction through the forwarding instruction in the action domain in the preset forwarding rule.
In some optional implementations, the preset forwarding rule may be implemented by an OpenFlow protocol.
In this embodiment, the meta information of the message information is obtained by extracting feature information in the message information, and includes a source IP address, a source port, a destination IP address, a destination port, and a transport layer protocol.
And 203, counting to obtain the flow information of the virtual switch through the aggregation module based on the meta information of the message information.
In this embodiment, the aggregation module may obtain corresponding flow information according to statistics of all or part of the meta information of the message information. For example, the aggregation module may count the message information with meta information "a source IP address is a, a source port is B, a destination IP address is a ', a destination port is B', and a transport layer protocol is C", to obtain the flow information corresponding to the meta information. The flow information includes, but is not limited to, the number of packets, the number of bytes, the start time and the end time of the flow information.
In some optional implementations, the meta information of the message information further includes: the system comprises a local area network address and a forwarding port, wherein the forwarding port is used for data transmission between a virtual switch and a virtual machine in a virtual network. The execution body can obtain the flow information for distinguishing the virtual private network according to the meta information of the message information. Specifically, the execution main body identifies the virtual private network attribute information corresponding to the message information through the aggregation module according to the local area network address and the forwarding port of the message information; and based on the attribute information of the virtual private network, counting by an aggregation module to obtain the flow information of the virtual private network corresponding to the message information.
In the embodiment, the execution main body forwards the meta information of the matched message information to the aggregation module for statistics based on the matching domain of the forwarding rule, so that unnecessary message information is prevented from being counted; and only the meta information of the message information is forwarded to the aggregation module, so that the data volume of the meta information is small, and the overhead during data forwarding is reduced.
Fig. 3 schematically shows an application scenario of the flow information collection method of the virtual network according to the present embodiment. The server 301 is provided with a virtual server and a virtual switch, and the virtual server forwards and branches network data information through the virtual switch to provide virtual network services for a plurality of companies, including a company 302, a company 303, and a company 304. The method comprises the steps that a server obtains message information of a plurality of companies in the process of providing virtual network service, the server obtains the message information of the companies 302 and 303 through matching of matching domains of preset matching rules, the meta information of the message information is forwarded to an aggregation module appointed by a forwarding instruction through the forwarding instruction in an action domain of the preset forwarding rule, and flow information of the companies 302 and 303 is obtained through statistics of the aggregation module.
With continuing reference to fig. 4, a schematic flow chart 400 illustrating another embodiment of a method for flow information collection for a virtual network in accordance with the present application is shown that includes the steps of:
In this embodiment, step 401 is performed in a manner similar to step 201, and is not described herein again.
In this embodiment, the access identifier is used to characterize whether the security access rule of the virtual network accepts the access request of the terminal corresponding to the message information.
In the process of shunting the message information, the virtual switch in the execution main body can identify whether the message information is admitted by the security access rule or not, and adds corresponding characteristic information to the message information based on the identification result of the secured access rule; and adding an access identifier for the message information by the execution main body by identifying the characteristic information whether the message information is accepted by the security access rule of the virtual network or not.
In this embodiment, the forwarding action of the execution subject on the meta information of the packet information is performed in a similar manner to the forwarding action in step 202, but the difference is that the meta information of the packet information in this embodiment includes the access identifier.
And step 404, counting by the aggregation module based on the meta information of the message information to obtain the flow information of the virtual switch.
In this embodiment, the execution main body may obtain, through the aggregation module, the corresponding flow information according to the meta information statistics of the message information. In some optional implementation manners, the meta information of the message information includes an access identifier, and the execution subject may statistically obtain flow information that distinguishes whether the flow information is accepted by the security access rule according to the access identifier of the message information.
In some optional implementations, the execution body may obtain flow information according to the meta information statistics of the part of the message information, and perform statistics again based on other meta information on the basis of the flow information. For example, the execution main body obtains the flow information X according to the meta information source IP address, the source port, the destination IP address, the destination port, and the transport layer protocol statistics of the message information, and on the basis of the flow information X, performs statistics again on the flow information X according to the access identifier, and distinguishes whether the flow information X is the flow information accepted by the security access rule.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, a flow 400 of the flow information collection method of the virtual network in this embodiment specifically illustrates that the meta information of the message information may further include an access identifier, and the access identifier may be used to distinguish whether the flow information is accepted by the security access rule.
