Example two
The method is used for testing whether the edge device can forward the data stream according to the flow table issued by the controller and the forwarding strategy in the initialization configuration template.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a benchmark test flow of controller capability based on a software-defined wide area network according to a second embodiment of the present application. The method comprises the following specific steps:
M addresses, such as SIP-1, …, SIP-M, are configured on one test terminal as source addresses for initiating M data flows, and an address is configured on the other test terminal as a common destination address for the M initiated data flows.
And sending the generated M data streams by the test terminal configured with a plurality of different addresses.
In the embodiment of the present application, the multiple data streams are data streams with different sources, and therefore, when forwarding, the first packet data of each data stream is sent to the controller to determine the forwarding path. The controller determines a forwarding path according to a network topology forwarding strategy and the like, and issues a forwarding flow table.
The specified data transmission policy may be: a hop count minimum strategy, a delay minimum strategy, a load balancing strategy and the like.

the load balancing policy may be a flow-by-flow load balancing policy or a packet-by-packet load balancing policy.
In this embodiment of the present application, when testing whether data transmission can be performed according to a specified policy for the edge device, the policies in the foregoing examples may be tested one by one, or one or more of the policies may be selected according to actual needs to be tested, which is not limited in this embodiment of the present application.
When the edge device forwards the data stream, if the first packet is not the packet, that is, the data stream table exists, the edge device determines a forwarding path of the data stream according to the data stream table and a data transmission strategy configured during initialization.

And 204, verifying whether the forwarding of the multiple data streams is carried out according to the data transmission strategy appointed in the initialization configuration template according to the inquired forwarding paths of the M data streams.
The transmission path of the data stream can be determined according to the port sent by each data stream and the network topology of all the edge devices, so as to verify whether the edge devices have the flow table issued by the controller and the capability of transmitting the data stream according to the transmission strategy in the initialization configuration template.
In the embodiment of the application, when verifying whether the edge device has the capability of forwarding the data stream according to the stream table issued by the controller and the forwarding strategy in the initialization configuration template, a network state query request can be initiated to the SD-WAN controller.
The SD-WAN controller can control the forwarding of the data stream, and when each edge device inquires a forwarding path to the SD-WAN controller, the SD-WAN controller can record the forwarding path of the data stream, the forwarding flow of each link and the updating of network topology, so as to verify whether the edge device has a stream table issued by the controller and the capability of initializing a forwarding strategy in a configuration template to forward the data stream.
EXAMPLE III

and when the edge equipment receives the data transmission strategy, updating the data transmission strategy in the local initial configuration template by using the received data transmission strategy.
The change of the data transmission policy may be changed from one to another, for example, a minimum delay policy is changed into a minimum routing hop count policy, or the policy may be updated between two other policies, which is not limited in the embodiment of the present application.
In a specific implementation, when a network topology between edge devices is deployed, it is preferable to deploy two links with different time delays and different hop counts for the edge devices, so as to better distinguish link transmission strategies.
Example four

And step 403, waiting for a third preset time.
The third preset time can be set according to an actual test scene, and it is only required to ensure that the transmission of the P data streams is finished.
Since the network formed by the edge devices deployed in this embodiment is a ring topology, at least two links reach the edge device at the opposite end, and therefore, when one of the links is disconnected, the other link is switched to forward traffic.
The method further comprises:
restoring the disconnected data transmission link between the two edge devices;
initiating a query request to the edge device accessed by the test terminal;
and verifying whether the edge equipment correctly switches the forwarding paths of the data streams after the link is recovered according to the queried forwarding paths of the data streams.
The link recovery can be carried out in the data stream transmission process, and also can be carried out when the data stream is not transmitted; if the data stream is recovered during the transmission process of no data stream, the transmission of the P data streams can be initiated again to verify whether the transmission path of the data stream is switched.
The link convergence time, as well as the link probing capabilities of the edge devices, may also be determined by querying the data forwarding time.

The source addresses of the multiple data streams may be the same or different; the destination addresses may be the same or different.
The fourth preset time can be set according to an actual test scene, and it is only required to ensure that the transmission of the T data streams is finished.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating an edge device capability benchmark test based on a software-defined wide area network according to a sixth embodiment of the present application. The method comprises the following specific steps:
When the edge device receives a request for accessing the URL, the edge device determines that a URL protection strategy is set locally, and then the request is prevented from being forwarded, namely the request is not sent to a controller, a local forwarding flow table is not searched, forwarding is directly prevented, or the request is directly discarded.
This embodiment enables verification of the URL filtering capabilities of the edge device.
Based on similar implementation, the data flow prohibited from being forwarded can be set;
whether the edge device can prevent the forwarding of the corresponding data flow is verified by initiating the data flow of which the forwarding is forbidden, namely whether the edge device has the firewall capability or not is verified.
Such as configuring the forbidden HTTP traffic on edge device a.
And initiating HTTP download flow through a test terminal accessed to the edge equipment, wherein the bandwidth of the HTTP flow is 0, and if the download fails, the firewall strategy of the SD-WAN edge equipment is proved.
