The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of a prior art software defined optical network test scheme; the current scenario for validating SDON service creation is shown in fig. 1. The test controller sends a service creation request to the multi-domain controller through a northbound interface of the restful API, and the multi-domain cooperative controller returns a 200ok message of the restful to the test controller to complete a service interaction process with the test controller.
The tester verifies whether the service of the underlying network is successfully created by initiating the meter service flow.

However, in the prior art, after the multi-domain cooperative controller returns a restful 200ok message to the test controller, the message interaction flow with the test controller is completed, but it cannot be guaranteed that the service of the underlying network has been successfully created. Whether the service is created successfully or not needs to be verified by the instrument sending flow, the current technical scheme needs a tester to manually initiate the service flow, and the manual participation interrupts the testing process, so that the flow of creating or deleting the service of the instrument can be tested and verified only once.
In addition, the current test method cannot verify the stability and reliability of the controller in the long-term operation process and the connection creation success rate and failure rate in the long-term operation process.
FIG. 2 is a schematic diagram of an embodiment of a software defined optical network performance testing system according to the present invention;
the invention provides a software defined optical network performance test system, the software defined optical network includes a multi-domain cooperative controller, a plurality of domain controllers, the multi-domain cooperative controller is connected with each domain controller through an interface between controller layers, each domain controller is respectively connected with an optical transmission network domain or a grouped optical transmission network domain through a southbound interface, the software defined optical network performance test system includes: test controller, instrument control agent, data instrument.

Fig. 3 is a schematic diagram of a single-service embodiment of the software-defined optical network performance testing method of the present invention. The embodiment of the invention also comprises a software-defined optical network performance test method, which is used for the software-defined optical network performance test system in any embodiment of the application and comprises the following steps:
step 11, testing the controller at T1A connection establishment request is sent to a multi-domain cooperative controller at any moment;

Further, the software defined optical network performance testing method also comprises the following steps
And step 16, after the controller waits for the time T', executing the steps 11-15 again.
It should be noted that, in the long-term operation process, connection establishment and deletion of a single service may be initiated, and connection establishment and deletion of multiple services may also be initiated.
Fig. 4 is a schematic diagram of a multi-service embodiment of the method for testing performance of a software defined optical network according to the present invention. As an embodiment of further optimizing the software-defined optical network performance test method of the present application, the test controller continuously initiates a connection establishment request to the multi-domain cooperative controller for multiple times and receives a connection establishment success message; the test controller continuously sends a plurality of service flow initiating requests and service flow deleting requests to the instrument control agent; and the test controller continuously initiates a connection deletion request to the multi-domain cooperative controller for multiple times and receives a connection deletion success message. Specifically, the process of simultaneously initiating the long-term operation stability and reliability of a plurality of service flow verification controllers in the same period comprises the following steps:
step 21, the test controller is in T11Initiating a connection establishment request of the 1 st service to a multi-domain system controller at any time;
step 22, the test controller is in T12Receiving a message of successful creation of the 1 st service returned by the multi-domain cooperative controller at all times, and simultaneously initiating a connection creation request of the 2 nd service;

step 25, at time T13After receiving n notifications of stopping sending of concurrent flow sent by an instrument control agent, a test controller sends a deletion request of a 1 st service to a multi-domain cooperative controller;
step 26, executing deletion process of N services in series, and executing the deletion process at time Tn3The test controller receives the message of successful deletion of the nth service returned by the cooperative controller;
and 27, after the controller is tested for the waiting time T', executing the steps 21-26 again, and continuing to initiate the processes of creating the next n services, verifying the sending flow of the instrument and deleting the n services.
The test flow described above may be set in the test controller for the number of repetitions, or may run until manually stopped.
It should be noted that in the flows of the embodiments illustrated in fig. 3 to 4, after the message flows of the test controller and the cooperative controller are completed interactively, it is necessary to wait for a time T or T "to continue the next operation, which is because it cannot be guaranteed that the service has been successfully created in the underlying network after the simple message interaction flow is completed, and therefore, it is necessary to set an acceptance check wait to ensure that the service of the underlying network has been successfully created.
Fig. 5 is a schematic diagram of a performance test latency value taking method. In order to ensure that sufficient test pressure can be provided during the reliability test, and the upper limit of the performance of the controller is tested as much as possible, T, T 'and T' need to be set reasonably. The 3 moments can be set in the manner as shown in fig. 5. In fig. 5, the test instrument always sends traffic, the test controller initiates a connection deletion process, and after waiting for time T, initiates a connection creation process, and monitors the time of service interruption by the instrument.
Preferably, in the method for testing performance of a software-defined optical network according to the embodiment of the present application, T ═ 1.5 × Z; z ═ Y- (T)2’-T1') - (S-X); wherein,
T1': the moment test controller sends a connection establishment request message to the cooperative controller;
T2': the test controller receives a successful connection establishment message of the cooperative controller at the moment;
T3': before time T1', the test controller sends a connection deletion request message to the cooperative controller;
T4': before the time T1', the test controller receives a connection deletion success message of the cooperative controller;
s: from T4To T1', the waiting time of the test controller;
X：T4between' and service interruptionA delay time;
y: under the condition that the data instrument continuously sends out the service flow, the instrument monitors the obtained service interruption duration;
z: at T2' delay time between time and traffic recovery.
Further preferably, the software defines an optical network performance testing method, T' ═ 3T.
It should be noted that after the creation message flow is completed, the underlying network device may still wait for time Z to complete the creation of the service connection.
Here, Y is the service interruption duration measured by the meter, and if the flow is interrupted, the meter sending flow is the value of the number of packets lost by the meter/sending message rate.
The obtained Z value mainly guarantees that the underlying network can complete the service creation or deletion process after the signaling process is finished at the Z time, because the signaling time for creating the service between the controller and the device can be obtained by packet capture, but after the signaling is completed, the underlying network cannot guarantee that the actual service creation can be completed, the specific device configuration is crossed, and the service delivery requires time. And Z is to ensure that the underlying network can complete service creation.
In an embodiment of the method for testing performance of a software-defined optical network, to simplify the calculation of Z, the method further includes the following steps: and gradually reducing the value of S to obtain that S is X when the service creation is unsuccessful.
We can multiply the estimated Z value by a coefficient to further guarantee the successful creation or deletion of the service, i.e. T (creation guarantee latency) ═ T "(deletion guarantee latency) ═ 1.5 times Z.
T' is the time for the meter to send the flow verification service to be successful, and this value may be 3 times Z, or may be set to a fixed interval, such as 5s, if the value of Z is too small.
It should be noted that the technical key points of the present invention are: the test controller and the instrument are linked to realize the automatic flow of creating service, verifying whether the instrument distribution service is successful or not and deleting the service, and the stability and reliability index of the controller in the long-term operation process can be verified by repeating the flow. In addition, the method for reasonably setting the waiting time T and T' of the test controller ensures that the service of the bottom physical network can be successfully created and deleted, and simultaneously can provide enough test pressure and test the upper limit of the performance of the controller as much as possible.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
