Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The embodiment of the invention provides a data processing method which is applied to a control end and a data end of a virtual switch. The virtual switch may be installed in a server, thereby enabling the server to function as a virtual switch.
Referring to fig. 1, the data processing method may include:
s11, the data end sends a rule request message to the control end.
The data end in this embodiment may be referred to as a data forwarding plane, and the control end may be referred to as a control plane. The data forwarding plane forwards data, for example, forwards target data, but before forwarding, it needs to query whether the target data has a corresponding data forwarding rule, if so, the target data is directly forwarded according to the data forwarding rule, if not, the control plane needs to provide the corresponding data forwarding rule, and at this time, a rule request message (packet in) is sent to the control plane, where the rule request message is used to request the data forwarding rule of the target data, so that the control plane queries the data forwarding rule corresponding to the target data.
In addition, the rule request message carries a first packet of target data to be forwarded, and is used for informing the control terminal what the message needs to be forwarded, so that the control terminal can determine the data forwarding rule according to the content of the first packet.
And S12, the control terminal generates a message discarding rule.
And S13, the control end sends the message discarding rule to the data end.
When a virtual machine migration scenario exists, if a virtual machine is migrated to another digital machine, at this time, since the data forwarding rule on the new digital machine is blank, when a data forwarding plane needs to forward a large amount of data, a large amount of rule request messages need to be sent to the control plane, and a certain time is required for the data forwarding rule corresponding to the control plane query rule request message, a large amount of rule request messages are accumulated on the control plane. On the other hand, if the data forwarding plane does not receive the data forwarding rule, the data forwarding plane may continuously send the rule request message to the control plane, which may also cause the control plane to receive a large amount of messages again, further aggravating the accumulation of the control plane, and thus the whole control plane and the data forwarding plane may be vicious and circulated, resulting in an excessive task load of the control plane.
In order to avoid the above phenomenon, in this embodiment, after receiving the rule request message, the control end generates and issues a message discarding rule to the data end, where the message discarding rule is used to instruct the data end to stop sending the rule request message to the control end. That is, after receiving the message discard rule, the data forwarding plane does not repeatedly send the rule request message, and also discards the rule request message that has just been sent. Therefore, the rule request message is sent only once, and the data receiving amount and the processing amount of the control plane are further reduced. In addition, the message discarding rule is low in priority, the data forwarding rule is higher in priority than the message discarding rule, and the data forwarding rule is preferentially executed after the data forwarding rule is received.
In a preferred implementation scheme, in order to avoid that the control plane generates and issues the message discarding rule after receiving the rule request message, the embodiment sets that the message discarding rule is issued only when receiving a specific rule request message.
Specifically, the message type of the rule request message is determined, and if the message type is the target message type, a message discarding rule is issued to the data terminal.
The control plane receives a large number of messages, some messages are used for requesting a data forwarding rule, some messages are other services, at this time, the control plane needs to analyze the message type of the received messages, and if the message type is the target message type, the control plane generates and issues a message discarding rule. The target message type is the message type of the message for requesting the data forwarding rule.
In addition, in order to ensure that the data forwarding plane can still send the rule request packet when the data forwarding plane does not receive the data forwarding rule for a long time, and the control plane is left with enough time to process the accumulated rule request packet, in this embodiment, the data valid time of the packet discarding rule is set, and the data valid time is sent to the data terminal; and within the data valid time, the data end stops sending the rule request message to the control end. And if the message forwarding plane detects that the effective data time of the message discarding rule reaches, the data end sends the rule request message to the control plane again. The control plane receives the rule request message again, wherein the data valid time may be 10 seconds.
And S14, the data end stops sending the rule request message to the control end.
And S15, the control terminal inquires the data forwarding rule corresponding to the rule request message.
The non-sequential execution sequence of step S14 and step S15 may be that the data end stops sending the rule request message to the control end in the process of the control end querying the data forwarding rule corresponding to the rule request message. Or, if the amount of data to be processed by the control end is large, the data end stops sending the rule request message to the control end before the control end queries the data forwarding rule corresponding to the rule request message.
The data forwarding rule corresponding to the rule request message is stored in the database of the control surface, and at this moment, the control surface queries the data forwarding rule corresponding to the target data according to the target data carried by the rule request message.
In this embodiment, the data forwarding rule with high priority is searched preferentially, and when the data forwarding rule with high priority does not exist, the data forwarding rule with low priority is searched again. Therefore, the highest level of the data forwarding rule can be ensured, and the data forwarding is most accurate.
In addition, when the data forwarding rule corresponding to the target data is queried, because in step S13, the data end discards the sent rule request packet, and the sent rule request packet carries a first packet of the target data to be forwarded, so as to avoid discarding the first packet of the target data because the data end does not transmit the first packet, at this time, the control plane forwards the rule request packet to a target receiving object in the requested data forwarding rule, so as to avoid adverse effect of discarding the first packet in the normal request traffic.
And S16, the control end sends the data forwarding rule to the data end.
And S17, the data terminal forwards the target data according to the data forwarding rule.
After the control terminal inquires the data forwarding rule corresponding to the rule request message, the control terminal issues the rule to the data terminal, and the data terminal forwards the target data according to the data forwarding rule.
In addition, after the data forwarding plane receives the data forwarding rule, the data forwarding plane configures an invalid identifier for the packet discarding rule, that is, the packet discarding rule issued before the control plane is an invalid rule, and the data forwarding plane does not need to execute the packet discarding rule any more.
In this embodiment, when the data end has no data forwarding rule of the target data, the control end receives a rule request message sent by the data end, and then issues a message discarding rule to the data end to instruct the data end to stop sending the rule request message to the control end, so that the control end receives the rule request message once, data of the rule request message received by the control end is reduced, and further, the receiving and processing task amount of the control end is reduced, and the burden of the control end is reduced. In addition, the stability of the control plane can be ensured when a large increment request is met.
