The SD-WAN service enables a network connection between a company headquarters and branches of the company, cloud services purchased by the company, which is generally provided by one operator. However, as the demand of network services increases, sometimes the network resources covered by one operator cannot meet the requirement of the customer on network interconnection. As shown in fig. 1, the company headquarters in country a selects a first network of operator a, and the branch companies in country B select a second network of operator B. When a source site of a company headquarter and a destination site of a branch company need to establish network connection, transfer needs to be carried out through a third party manufacturer, and interconnection of a first network of an operator A and a second network of an operator B is achieved. However, due to the hardware devices of the third-party vendors and the like, the user experience is often poor through the network interconnection transferred by the third-party vendors. To solve this problem, as shown in fig. 2, an embodiment of the present invention provides a network interconnection system between different operators without forwarding performed by a third party vendor.

As shown in fig. 2, the network interconnection system includes a first network and a second network, the first network includes a first service orchestrator, at least one site, and at least one point of presence, wherein the site may be a source site and/or a destination site. The second network includes a second traffic orchestrator, at least one site, which may be a source site and/or a destination site, and at least one point-of-presence.

The first service orchestrator and the second service orchestrator are respectively connected with sites and access points in respective networks and are used for orchestrating various network services in the networks. The first service orchestrator comprises a resource management module, a performance management module, a topology management module, a service management module and a monitoring and warning module.

The system comprises a resource management module, a topology management module, a service management module and a monitoring and alarming module, wherein the resource management module is at least used for detecting and recording state information and port occupation information of a site, the performance management module is at least used for testing and recording various parameters in a network, the topology management module is used for planning and establishing topology in the network and recording topology information, the service management module is used for recording operation state information of a service, and the monitoring and alarming module is used for monitoring whether the service normally operates.

In the same network, the site is connected with a point of presence through the network, wherein the point of presence is used for establishing the connection between the first network and the second network.

As shown in fig. 3, an embodiment of the present invention provides a network interconnection method for the above network interconnection system, which includes S301 to S305.

S301, the first service orchestrator acquires a first data transmission service request from a first source site to a first destination site, wherein the first data transmission service request is initiated by a first network.

The first source site is located in a first network, the first destination site is located in a second network which belongs to a different operator from the first network, and the first service orchestrator is a service orchestrator of the first network.

After the first service orchestrator obtains a first data transmission service request initiated by the first network from the first source station to the first destination station, a situation may occur that resources of the first source station do not meet a requirement of the first data transmission service for the resources, for example, the source station has no available port, or the source station is in an unavailable state, where the unavailable situation may be caused by shutdown, disconnection, or damage of the first source station. In this case, it is not possible to establish a network connection from the first source station to the first destination station, and further, it is not necessary to perform the subsequent steps provided by the embodiment of the present invention. Therefore, in order to improve the efficiency of network interconnection, after the first service orchestrator obtains the first data transmission service request from the first source station to the first destination station, which is initiated by the first network, it should also be determined whether the first source station has available resources. Optionally, referring to fig. 4, the method according to the embodiment of the present invention further includes S302 a:

s302a, the first service orchestrator determines whether the resource of the first source site meets the requirement of the first data transmission service for the resource in the first data transmission service request.

Specifically, the first service orchestrator calls a resource management module, and the resource management module checks whether the first source site has available resources, including whether an available port exists and whether the first source site is in an available state.

When the first service orchestrator determines that the resources of the first source site meet the requirements of the first data transmission service for the resources, S304 is performed.

By the method provided in S302a, only when it is determined that the resource of the first source site meets the requirement, the next operation is performed.

It should be noted that, if the resource of the first source station does not meet the requirement of the first data transmission service for the resource, one source station needs to be determined again, and whether the resource of the source station meets the requirement of the first data transmission service for the resource is determined, until a source station whose resource can meet the requirement of the first data transmission service for the resource is found, and the source station is determined as the first source station.

Further, if the resource of the first destination site does not meet the requirement of the first data transmission service for the resource, in such a case, it is also impossible to establish a network connection from the first source site to the first destination site. Therefore, in order to improve the interconnection efficiency, it should be further determined whether the first destination site has available resources, and therefore, before the first service orchestrator determines the first target interconnection point in the plurality of sets of first interconnection points, the method provided by the embodiment of the present invention, as shown in fig. 4, further includes S302b-S303 b:

s302b, the first service orchestrator sends the first test information to the second service orchestrator.

The first test information is at least used for indicating the second service orchestrator to judge whether the resource of the first destination site meets the requirement of the first data transmission service on the resource. The first test information comprises a first data transmission service request and the second service orchestrator is a service orchestrator of a second network.

S303b, the first service orchestrator determines whether the first feedback information is received.

When the first service composer receives the first feedback information sent by the second service composer, S304 is performed.

The first feedback information is used for indicating that the resource of the first destination station meets the requirement of the first data transmission service for the resource.

It should be noted that, the two determination processes of determining whether the resource of the first source station meets the requirement of the first data transmission service for the resource and determining whether the resource of the first destination station meets the requirement of the first data transmission service for the resource, which are provided by the embodiment of the present invention, are executed in no order, and may be executed simultaneously, or may be executed by determining the first source station first and then determining the first destination station, or may be executed by determining the first destination station first and then determining the first source station.

S304, the first service orchestrator determines a first target interconnection point in the multiple groups of first interconnection points.

The first interconnection point is a pair of point-of-presence connecting a backbone network of the first network and a backbone network of the second network.

The first network and the second network are connected through a plurality of groups of first interconnection points, and one point of presence of the first network and one point of presence of the second network are connected to form a group of first interconnection points.

In a method provided in an embodiment of the present invention, referring to fig. 4, S304 specifically includes S3041a-S3042 a:

s3041a, the first service orchestrator tests operation parameters of the plurality of sets of first interconnection points.

In an implementation method provided in the embodiment of the present invention, a first service orchestrator calls a performance management module to test an operation parameter of a first interconnection point. Wherein the operational parameters include at least throughput and latency.

Specifically, the performance management module tests the first interconnection point through RFC2544 performance testing, and determines the operating parameters of the first interconnection point. The RFC2544 standard is issued by the Internet Engineering Task Force (IETF), and is used to objectively evaluate the performance of network devices and define a test method and a test report format.

The throughput in the operation parameters refers to the maximum data traffic that can be forwarded under the condition that the device to be tested does not lose packets. Usually measured as the maximum number of packets or bytes passing per second. Since there may be other traffic flows already between the point of presence of the first interconnection point, the throughput at this time indicates the maximum traffic that can still be carried between the devices.

The time delay in the operating parameters may be obtained by: sending a certain amount of data packets, recording the time T1 when the intermediate data packets are sent out and the time T2 when the intermediate data packets arrive at a receiving port after being forwarded by the testing equipment, and then calculating according to the following formula:

time delay is T2-T1;

where T2 is the time when the first bit of the output frame arrives at the output port and T1 is the time when the last bit of the input frame arrives at the input port.

Specifically, the reference of the test message sent by the first orchestrator to the performance management module is as follows:

srcip (source IP address): an IP address of a point of presence belonging to a first network in a first Internet node;

desip (destination IP address): an IP address of a point of presence in the first nexus that belongs to the second network;

size (test pack Size): in units of bits;

send-interval: in seconds;

test-duration (duration): in seconds.

The format of the message returned by the performance management module to the first service orchestrator is as follows:

throughput: the maximum flow which can be transmitted between the access point belonging to the first network in the first interconnection point and the access point belonging to the second network in the first interconnection point;

latency (Latency): and time delay between a point of access belonging to the first network in the first interconnection point and a point of access belonging to the second network in the first interconnection point.

Similarly, the throughput and the time delay among the groups of first interconnection points can be measured.

S3042a, the first service orchestrator determines a first interconnection point in which the operation parameter matches with the operation parameter of the first data transmission service request, as a first target interconnection point.

And determining the first interconnection point with the throughput being greater than the throughput required by the first data transmission service and the time delay being less than the time delay required by the first data transmission service in the multiple groups of first interconnection points as a first target interconnection point.

Further, if a plurality of groups of first interconnection points meet the requirements, determining the first interconnection point with the throughput and the time delay which are closest to the throughput and the time delay required by the first data transmission service as a first target interconnection point so as to realize reasonable allocation of resources; or determining the first interconnection point with the maximum throughput and the minimum time delay as the first target interconnection point, so as to improve the efficiency of the first data transmission service to the maximum extent.

When the service of the first service orchestrator is busy or the hardware configuration of the first service orchestrator is low, the second service orchestrator may also test multiple sets of operating parameters of the first interconnection point, and at this time, as shown in fig. 4, S304 specifically includes S3041b-S3042 b:

s3041b, the first service orchestrator sends a first instruction to the second service orchestrator.

The first instruction is used for instructing a second service orchestrator to test operation parameters of multiple groups of first interconnection points, determining a first interconnection point with the operation parameters matched with the operation parameters of the first data transmission service request in the first interconnection points as a first target interconnection point, and sending information of the first target interconnection point to the first service orchestrator. The second service orchestrator is a service orchestrator of a second network.

The method for the second service orchestrator to test the operation parameters of the multiple sets of interconnection points and determine the first target interconnection point is similar to S3041a to S3042a, and is not described herein again.

S3042b, the first service orchestrator receives the information of the first target interconnection point sent by the second service orchestrator.
