For a monitoring platform performance pressure test environment, the number of monitoring devices and the number of services to be simulated are very large, and fig. 1 of the embodiment is implemented by using multiple SDN controllers. It is easy to understand that the SDN master server, the first SDN controller, and the second SDN controller are not different, and may be implemented by one SDN controller if the SDN controller has sufficiently strong performance. In addition, the SDN host controller may be separately provided, or one SDN host controller may be selected from the first SDN controller and the second SDN controller to serve as the host controller, which is not described herein again.

However, in the test environment, only a part of the functions may be tested, or the whole business process may be tested. In the technical scheme, the SDN-based large-pressure service testing method further comprises the following steps:
and the SDN controller receives a service request message sent by the monitoring platform, modifies monitoring equipment information in a service response message of the monitoring equipment into corresponding monitoring equipment information in the service request message, and sends the monitoring equipment information to the monitoring platform.
And the SDN controller receives the code stream sent by the monitoring platform, copies the code stream according to the maintained monitoring service list, and sends the copied code stream to a corresponding service client according to a code stream sending strategy.
In the following description, the SDN controllers are divided into an SDN main controller, a first SDN controller, and a second SDN controller, and multiple SDN controllers are adopted to facilitate realization of a simulation test of a large-pressure monitoring device and/or a service client.
In a first embodiment, a first SDN controller processes a registration packet.
The method comprises the steps that a first SDN controller receives a registration message sent by monitoring equipment and reports the received registration message to an SDN main controller;
the SDN main controller sends the received registration message, the parameters of each monitoring device to be copied and a message sending strategy to each first SDN controller;
the first SDN controller modifies a corresponding message field according to the parameters of the monitoring equipment to be copied, and copies the message;
and the first SDN controller sends the copied registration message to the monitoring platform according to a message sending strategy issued by the SDN main controller.
Taking a registration process as an example, the monitoring device sends a registration message to the monitoring platform, and the registration message passes through the first SDN controller. The first SDN controller reports the received registration message to an SDN main controller, the SDN main controller issues the received registration message to each first SDN controller, and parameters and message sending strategies of each monitoring device to be copied, and the parameters of the monitoring device to be copied include but are not limited to MAC addresses, IP addresses, device IDs and other necessary parameters.
After receiving the original registration message, the parameters of the monitoring device to be copied and the message sending policy, the first SDN controller parses the original registration message, modifies corresponding message fields according to the parameters of the monitoring device to be copied, such as modifying a source MAC address, a source IP address, a device ID, and the like of the registration message, and performs 1: and N copies are carried out to obtain different registration messages of the source MAC address, the source IP address and the equipment ID, which is equivalent to that N monitoring equipment sends out the registration messages. The number of replications N is determined according to the performance of the SDN controller and the number of monitoring devices that need to be tested.
According to the embodiment, different message sending strategies can be issued to test the monitoring platform according to different performance test requirements. Each copied message can be immediately sent after being modified so as to achieve high concurrent registration performance test of the monitoring platform; the transmission control can be performed on each copied and modified message according to a certain transmission delay strategy so as to achieve the actual use environment.
Through the steps, the first SDN controller copies N test messages, namely simulates N monitoring devices to initiate registration to the monitoring platform, the monitoring platform performs registration response and sends response messages, and the first SDN controller receives corresponding response messages.
By the steps, in a centralized control mode, under the condition that the first SDN controller does not need any monitoring equipment information, the SDN main controller controls the copying and modification of the SDN controller messages to the specified fields, and the monitoring equipment 1: n replication effect, if each SDN server can replicate N devices under the condition of M SDN controller clusters, it is 1: (N × M) replication effects.
And in the second embodiment, the second SDN controller processes the service packet.
The second SDN controller receives a service message sent by the service client and reports the received service message to the SDN main controller;
the SDN main controller sends the received service messages to each second SDN controller, and parameters and message sending strategies of each service client to be copied;
the second SDN controller modifies the corresponding message field according to the parameters of the service client to be copied, and copies the message;
and the second SDN controller sends the copied service message to the monitoring platform according to a message sending strategy issued by the SDN main controller.
As shown in fig. 1, a service client sends a service packet to a monitoring platform, and the packet first passes through a second SDN controller.
The second SDN controller reports the received service message to the SDN main controller, and the SDN main controller sends the received service message to each second SDN controller, and parameters (including but not limited to MAC address and IP address of the service client, and some necessary parameters such as equipment ID of the service to be requested) of each service client to be copied, a message sending strategy and the like.
After each second SDN controller receives the original service request packet, the parameters of the service client to be copied, and the packet sending policy, the second SDN controller parses the original service request packet, and performs 1: and N is copied.
According to the embodiment, different message sending strategies can be issued to perform performance test on the monitoring platform according to different service performance test requirements. Each copied message can be immediately sent after being modified so as to achieve the high concurrent service performance test of the monitoring platform; the transmission control can be performed on each copied and modified message according to a certain transmission delay strategy so as to achieve the actual use environment.
The second SDN controller copies the N service packets, which is equivalent to simulating that the N service clients initiate services to the monitoring platform. The SDN main controller realizes that the monitoring service 1: n replication effects, if each second SDN controller can replicate N service packets under the condition of M second SDN controller clusters, what is achieved is 1: (N × M) replication effects.
And the third embodiment is that the monitoring platform sends the service request message to the monitoring equipment for processing.
When receiving a service request message from a monitoring platform to a monitoring device, a first SDN controller reports the received service request message to an SDN main controller, and the SDN main controller issues information of the monitoring device;
the first SDN controller modifies information of the monitoring equipment in the service request message, sends the service request message to the monitoring equipment, receives a service response message of the monitoring equipment, modifies monitoring equipment information of the received service response message into corresponding monitoring equipment information in the service request message, and sends the monitoring equipment information to the monitoring platform.
Preferably, the first SDN controller further performs caching after receiving the service response packet of the monitoring device, and sends the received service response packet of the monitoring device to the SDN host controller for caching.
When receiving a service request message from a monitoring platform to a monitoring device, a first SDN controller firstly checks whether a corresponding service response message exists in a current cache list, if so, copies the corresponding service response message, modifies information of the monitoring device in the service response message into corresponding monitoring device information in the service request message, and sends the monitoring device information to the monitoring platform;
and if the service request message is not reported to the SDN main controller, the SDN main controller checks whether a corresponding service response message exists in a current cache list or not, if so, the cached service response message is sent to the first SDN controller, the first SDN controller copies the corresponding service response message, and the information of the monitoring equipment in the service response message is modified into the corresponding monitoring equipment information in the service request message and sent to the monitoring platform.
After receiving the service message of the service client, the monitoring platform of this embodiment initiates a service request to the monitoring device, and sends a service request message.
In this embodiment, when receiving a service request packet from a monitoring platform to a monitoring device, each first SDN controller first checks whether a corresponding service response packet exists in a current cache list.
If so, copying a corresponding service response message, modifying fields (including but not limited to the MAC address, the IP address, the equipment ID and the like in the response message) related to the monitoring equipment in the response message into corresponding equipment information in the service request message, and sending the corresponding equipment information to the monitoring platform.
And when the checking result is that the service request message is not received, the first SDN controller reports the received service request message to the SDN main controller.
And after receiving the service request message, the SDN main controller checks whether a corresponding service response message exists in the current cache list.
If the SDN main controller detects that a corresponding service response message exists, the cached service response message is sent to the first SDN controller, the first SDN controller copies the corresponding service response message, and modifies fields related to monitoring equipment (including but not limited to MAC addresses, IP addresses, equipment IDs and the like in the response message) in the response message into corresponding equipment information in the service request message, and sends the corresponding equipment information to the monitoring platform.
And if the SDN main controller detects that no corresponding service response message exists, the SDN main controller issues device information (including but not limited to MAC address, IP address and device ID) of real monitoring devices to the first SDN controller.
After receiving the device information, the first SDN controller modifies fields such as an MAC address, an IP address, and a device ID of the service request packet into corresponding values of the real device, and sends the corresponding values to the real monitoring device.
And after receiving the service request message, the real equipment sends a response message to the first SDN controller.
The first SDN controller caches the received response message, copies a corresponding service response message, modifies fields (including but not limited to a MAC address, an IP address, a device ID, and the like in the response message) related to the monitoring device in the response message into corresponding device information in the service request message, and sends the device information to the monitoring platform. And meanwhile, the first SDN controller sends the corresponding message to an SDN main controller for caching.
The operation of the above steps ensures that the whole performance test environment only needs one real monitoring device, and the real monitoring device only needs to establish one path of service to complete the corresponding service operation of all the duplicated devices.
Thereafter, after the monitoring service is established, the monitoring device may send the code stream to the service client.
And fourthly, processing of the monitoring equipment sending code stream. And the first SDN controller receives the code stream sent by the monitoring platform, copies the code stream according to the maintained monitoring service list, and sends the copied code stream to the second SDN controller according to a code stream sending strategy issued by the SDN main controller.
The code stream sent by the monitoring equipment firstly passes through the first SDN server, the first SDN controller reports the received code stream to the SDN main controller, and the SDN main controller issues the received code stream and a sending strategy of the code stream to other first SDN controllers.
According to the service request message and the corresponding service request response received in the third embodiment, the first SDN controller maintains a list of monitoring services corresponding to the monitoring device, inserts corresponding information when a service is newly added, and deletes corresponding information when a service is deleted, where the list is shown in table 1.
| Device ID | Device MAC | Equipment IP | Send out a class port | IP of flow receiving end | Flow-receiving end port |
| Dev1 | MAC1 | IP1 | PORT1 | DST IP1 | DST PORT1 |
| Dev2 | MAC2 | IP2 | PORT2 | DST IP2 | DST PORT2 |
TABLE 1
And after receiving the code stream, the first SDN controller copies the code stream according to the list of the monitoring service and modifies a source MAC address, an IP address, a port, a destination IP address and a port. And according to a code stream sending strategy issued by the SDN main controller, sending control is carried out on each copied code stream.
It is easy to understand that the first SDN controller and the second SDN controller copy the monitoring device and the service client, and register response to a registration message and response to a service message of the monitoring platform are both sent to a copied MAC address and an IP address, so that copied address lists sent by the first SDN controller and the second SDN controller of the technical solution are sent to the SDN switch, and the SDN switch receives the copied address lists sent by the first SDN controller and the second SDN controller and forwards the received test message.
Specifically, the monitoring platform receives registration messages of different MAC addresses, IP addresses, and device IDs, at this time, the monitoring platform is different monitoring devices and sends registration request messages to the monitoring platform, and thereafter, the monitoring platform responds to each monitoring device with corresponding registration messages.
The MAC address and the IP address of the destination of the response message are copied by the first SDN controller, so that the first SDN controller receives the response message. The first SDN controller maintains a copied monitoring device parameter list (namely a copied address list), the SDN switch generates a forwarding flow table after receiving the copied address list issued by the first SDN controller, and directly forwards a response message of a destination MAC address and a destination IP address in the copied address list to the first SDN controller, so that the MAC and IP addresses of the copied monitoring device can be routed in a network.
Similarly, the monitoring platform receives service messages of different MAC addresses, IP addresses and equipment IDs of services to be requested, at the moment, the monitoring platform is different service clients to send the service messages to the monitoring platform, and then the monitoring platform initiates service request messages to corresponding monitoring equipment. After initiating a service request to the corresponding monitoring device, the monitoring platform receives a response message of the monitoring device. And then the monitoring platform sends a service response message to the service client, wherein the destination MAC address and the destination IP address of the service response message are copied by the second SDN controller, so that the service response message is received by the second SDN controller. Therefore, the second SDN controller maintains a parameter list (i.e., a copied address list) of the copied service client, and the SDN switch generates a forwarding flow table after receiving the copied address list issued by the second SDN controller, and directly forwards a service response packet of a destination MAC address and a destination IP address in the copied address list to the second SDN controller, so that the MAC and the IP address of the copied service client can be routed in the network.
The technical scheme also provides an embodiment of a large-pressure service testing system based on the SDN, which is used for performing performance pressure testing on a monitoring platform, and the large-pressure service testing system based on the SDN comprises the monitoring platform, a monitoring device and/or a service client, an SDN controller and an SDN switch, wherein:
