Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The networking method of the cloud network provided by the invention is further explained by a specific embodiment with reference to the accompanying drawings, and the embodiment does not limit the embodiment of the invention.
Referring to fig. 1, a flowchart of an embodiment of a method for networking a cloud network according to an embodiment of the present invention is provided. As shown in fig. 1, the method may include the steps of:
Step 101, creating a cloud enterprise network.
Step 102, loading two or more network instances to be networked to a cloud enterprise network.
In the embodiment of the present invention, the two or more network instances to be networked may include network instances of different forms, such as a VPC network instance, a private line network instance, a VBR (Virtual Border Router, border router) network instance, and the like. Two or more network instances to be networked may be in the same area or may be in different areas, which is not limited in the embodiment of the present invention.
Step 103, for each network instance, publishing the route in the network instance to the cloud enterprise network based on a preset route management policy, and learning the route of other network instances to the network instance.
In order to facilitate understanding of the embodiments of the present invention, the following description will collectively explain the above steps 101 to 103 in conjunction with a system architecture diagram of the cloud network shown in fig. 2:
The system architecture shown in fig. 2 includes 3 VPC network examples: VPC 1, VPC 2, VPC 3, and the 3 VPC network instances are distributed in different areas. In practice, in order to meet the requirement of interconnection of the 3 VPC network instances, the networking method of the cloud network provided by the embodiment of the present invention may be applied.
In the networking method of the cloud network provided by the embodiment of the invention, a cloud enterprise network is firstly created, then a cloud enterprise network management domain (cen domain) corresponding to a preset area is created in the cloud enterprise network as a routing management domain of the preset area, and specifically, the cloud enterprise network management domain corresponding to the preset area is created on a TGW (Transport GateWay, transmission gateway) of the cloud enterprise network.
Here, the preset area is any area involved in two or more network instances to be networked. For example, the 3 network instances illustrated in fig. 2 involve three areas, and then 3 cloud enterprise network management domains are created in the cloud enterprise network, cloud enterprise network management domain 1, cloud enterprise network management domain 2, and cloud enterprise network management domain 3, respectively.
It should be noted that, in the case of creating two or more cloud enterprise network management domains, the two or more cloud enterprise network management domains are interconnected two by two (e.g., a virtual tunnel is established between every two enterprise network management domains). For example, in fig. 2, the cloud enterprise network management domain 1 and the cloud enterprise network management domain 2 are interconnected, the cloud enterprise network management domain 2 and the cloud enterprise network management domain 3 are interconnected, and the cloud enterprise network management domain 1 and the cloud enterprise network management domain 3 are interconnected. In this way, the cloud enterprise network management domain can carry the interconnection of the cross-regional network instances and the routing forwarding function of the cloud enterprise network.
In the embodiment of the invention, after the cloud enterprise network management domain is created, an IP address and a domain identifier are allocated for the cloud enterprise network management domain. The IP address may be allocated to the cloud enterprise network management domain from IP network segments that are open to some of the preplanned underway networks (i.e., the physical network layer that carries the upper virtual network), and the domain identifier may be allocated to the cloud enterprise network management domain from one or more preplanned ranges, for example, from 10000 to 20000, from 50000 to 70000, and so on. It will be appreciated that not only is its IP address unique to the cloud enterprise network management domain, but its domain identification is also unique, i.e., the IP address and domain identification of different cloud enterprise network management domains are different.
Further, for each network instance to be networked, a virtual tunnel may be established between the network instance and its corresponding cloud enterprise network management domain based on the IP address and the instance identifier of the network instance, and the IP address and the domain identifier of the cloud enterprise network management domain corresponding to the network instance, so that loading the network instance to the cloud enterprise network may be implemented. Here, the cloud enterprise network management domain corresponding to the network instance refers to: the network instance corresponds to the same area as the cloud enterprise network management domain. For example, in fig. 2, a virtual tunnel is established between VPC1 and cloud enterprise network management domain 1, a virtual tunnel is established between VPC 2 and cloud enterprise network management domain 2, and a virtual tunnel is established between VPC 3 and cloud enterprise network management domain 3, so far, loading VPC1, VPC 2, and VPC 3 into the same cloud enterprise network is achieved.
In an embodiment, after a network instance to be networked is loaded into a cloud enterprise network, for each network instance, routes in the network instance are published into the cloud enterprise network based on a preset route management policy, and routes in other network instances are published into the cloud enterprise network are learned to the network instance.
For example, assume that in the initial state, route 10.10.0.0/24 is included in the local routing table of VPC 1, route 20.20.0.0/24 is included in the local routing table of VPC 2, and that the cloud enterprise network is not loaded with any network instance because in the initial state, and thus the local routing table of the cloud enterprise network is empty.
Thereafter, assuming that the VPC 1 is loaded into the cloud enterprise network, the VPC 1 publishes routes 10.10.0.0/24 included in the local routing table into the cloud enterprise network according to the above description, and at this time, the local routing table of the cloud enterprise network will be as shown in the following table 1:
TABLE 1
10.10.0.0/24 The next hop points to VPC 1
Further, assuming that VPC2 is also loaded into the cloud enterprise network, VPC2 also publishes routes 20.10.0.0/24 included in the local routing table into the cloud enterprise network as described above, at this point, the local routing table of the cloud enterprise network will be shown in table 2 below:
TABLE 2
10.10.0.0/24 The next hop points to VPC 1
20.10.0.0/24 The next hop points to VPC 2
Further, for VPC 1, there are routes published by other network instances VPC2 in the cloud enterprise network, and then VPC 1 may learn the routes published by VPC2 to VPC 1 from the cloud enterprise network local routing table illustrated in table 2, where the local routing table of VPC 1 is shown in table 3 below:
TABLE 3 Table 3
10.10.0.0/24 Next hop direction
20.10.0.0/24 Next hop pointing to cloud enterprise network
Similarly, for VPC 2, there are routes published by other network instances VPC 1 in the cloud enterprise network, and then VPC 2 may learn the route published by VPC 1 to VPC 2 from the cloud enterprise network local routing table illustrated in table 2, where the local routing table of VPC 2 is shown in table 4 below:
TABLE 4 Table 4
10.10.0.0/24 Next hop pointing to cloud enterprise network
20.10.0.0/24 Next hop direction
It follows that during route publication and route learning, both the cloud enterprise network and the network instance will identify where the learned route came from, thereby setting up the corresponding next hop for the learned route. Through the processing, a plurality of network instances can be interconnected and mutually visited.
Specifically, when network instances loaded to the same area of the same cloud enterprise network are mutually visited, a route which is matched to the next hop and points to the cloud enterprise network is matched, and then a route which is matched to the next hop and points to another network instance is searched for by searching a routing table of a management domain of the cloud enterprise network, so that the interconnection function is realized.
In addition, for inter-regional network instance interconnection and inter-visit, virtual tunnels between cloud enterprise network management domains through the cloud enterprise network are matched with routes transmitted to the other party, and the interconnection function is realized.
In addition, in the embodiment of the present invention, after the network instance is first loaded into the cloud enterprise network, the route in the network instance is published into the cloud enterprise network based on the preset route management policy, and the route in the cloud enterprise network is published into the network instance by other network instances, and when the route is newly added in the network instance, the route newly added in the network instance may also be published into the cloud enterprise network based on the preset route management policy, and the route newly added in the network instance is learned from the cloud enterprise network by other network instances.
When routes are deleted in a network instance, the routes in the cloud enterprise network and other network instances may also change accordingly. Specifically, when any route in an effective state in any network instance is deleted, the deleted route is deleted from the cloud enterprise network and other network instances respectively.
Therefore, the technical scheme provided by the embodiment of the invention can realize the dynamic release and learning of the route between different network instances.
According to the technical scheme provided by the embodiment of the invention, two or more network instances to be networked are loaded to the cloud enterprise network by creating the cloud enterprise network, the routes in the network instance are issued to the cloud enterprise network based on the preset route management strategy for each network instance, and the routes in other network instances are issued to the cloud enterprise network and are learned to the network instance.
Referring to fig. 3, a flowchart of an embodiment of another networking method of a cloud network according to an embodiment of the present invention is shown in fig. 3, where the flowchart is only exemplified by two network instances, and how to implement route distribution and learning between the two network instances based on a preset route management policy is described. As shown in fig. 3, the method may include the steps of:
step 301, the first network instance publishes the route in the first network instance to the cloud enterprise network.
For a private line gateway that turns on BGP (Border Gateway Protocol ), when it is loaded into the cloud enterprise network, the private line route may be automatically published to the cloud enterprise network based on BGP protocol.
Step 302, the cloud enterprise network determines a first route from routes issued by the first network instance, wherein the first route does not meet a preset first route conflict condition.
In one embodiment, the first route collision condition is: the routes in the cloud enterprise network in the effective state comprise routes issued by the network instance. For example, the first network instance publishes routes 172.10.1.0/24 to the cloud enterprise network, and the routes in the cloud enterprise network that are in effect include: 172.10.1.0/24.
In step 303, the cloud enterprise network sets the first route to a validity state, and sets other routes, except the first route, issued by the first network instance to a disabled state.
Therefore, the cloud enterprise network inherits the local priority principle when learning the route issued by other network examples, namely, the cloud enterprise network preferentially selects the local route to take effect under the condition that the route issued by the network example conflicts with the local route of the cloud enterprise network.
For example, the first network instance publishes routes 172.10.1.0/24 (next hop directed to a) to the cloud enterprise network, and the routes in the cloud enterprise network that are in effect include: 172.10.1.0/24 (next hop towards B), the cloud enterprise network sets routes 172.10.1.0/24 (next hop towards a) to a disabled state and routes 172.10.1.0/24 (next hop towards B) to a live state.
Step 304, the cloud enterprise network propagates the first route to the second network instance.
The cloud enterprise network propagates the first route published by the first network instance and validated in the cloud enterprise network to the second network instance, via step 304.
Step 305, the second network instance determines a second route from the first routes, where the second route does not meet a preset second route conflict condition.
The second route conflict condition is: the routes in the effective state in the network instance comprise large-segment routes corresponding to the first routes, and the large-segment routes refer to routes of corresponding network segments of the first routes. For example, the first route propagated by the cloud enterprise network includes 172.10.1.0/25, and the second network includes route 172.10.1.0/24, and since the corresponding network segment of route 172.10.1.0/24 includes the corresponding network segment of route 172.10.1.0/25, route 172.10.1.0/24 is referred to as the large segment route corresponding to route 172.10.1.0/25.
Step 306, the second network instance sets the second route to an effective state, and sets other first routes except the second route propagated by the cloud enterprise network to a disabled state.
It follows that a network instance will prefer to select a wide range of routes while learning routes published by other network instances.
For example, the cloud enterprise network propagates a first route including 172.10.1.0/25 and 172.10.1.0/23, and a second network instance including route 172.10.1.0/24, and since route 172.10.1.0/24 is a large segment route corresponding to route 172.10.1.0/25, the second network instance determines route 172.10.1.0/23 as the second route and sets route 172.10.1.0/23 to a live state and sets route 172.10.1.0/25 to a disabled state.
In addition, in an embodiment, when the large-segment route is deleted from the second network instance, the first route corresponding to the large-segment route in the second network instance is reset from the disabled state to the valid state.
For example, when the route 172.10.1.0/24 is deleted from the second network instance, the route 172.10.1.0/25 in the second network instance is reset from the disabled state to the active state.
As for the process that the second network instance issues the route in the second network instance to the cloud enterprise network and the first network instance learns from the cloud enterprise network to the second network instance issues the route, the steps 301 to 306 are similar to the steps described above, and the description thereof will not be repeated.
Through the flow shown in fig. 3, route release and learning among a plurality of network instances are realized, so that interconnection and mutual access among the plurality of network instances can be realized.
Furthermore, considering that if a network instance publishes a large number of routes to a cloud enterprise network, thereby affecting the stability of the cloud enterprise network, in an embodiment, it is proposed to limit the number of routes published in the cloud enterprise network.
Specifically, when the cloud enterprise network receives a first route issued by a network instance to the cloud enterprise network, firstly determining a difference N between the number of routes currently in an effective state in the cloud enterprise network and a preset threshold, wherein the preset threshold represents the upper limit of the number of effective routes in the cloud enterprise network, and the difference N represents the number of routes which can be issued in the cloud enterprise network.
And comparing the number of the first routes issued by the network instance with a difference value N, if the number of the first routes is smaller than or equal to N, setting all the first routes to be in an effective state, otherwise, if the number of the first routes is larger than N, setting the N first routes to be in an effective state. Accordingly, in the case where the N first routes are set to the validated state, the other first routes than the N first routes are set to the disabled state.
Through the processing, the number of effective routes in the cloud enterprise network is limited, and stability of the cloud enterprise network is guaranteed.
Further, the embodiment of the invention also provides: when any first route in the validated state is deleted from the cloud enterprise network, one first route in the disabled state is reset from the disabled state to the validated state. Therefore, the interconnection and the mutual access of more network resources can be realized as much as possible while the stability of the cloud enterprise network is ensured.
Alternatively, when one first route in the disabled state is reset from the disabled state to the valid state, the first route in the disabled state and having the earliest release time may be reset from the disabled state to the valid state.
In order to enable those skilled in the art to better understand the technical solution provided by the embodiments of the present invention, an application scenario diagram illustrated in fig. 4 is shown.
The application scenario diagram illustrated in fig. 4 includes two areas, beijing and Shanghai, each including a VPC network instance and a private line gateway network instance. In the prior art, if a user wants to realize interconnection and interview of network instances in two areas of Beijing and Shanghai, a plurality of VPC PEERING needs to be created, which not only results in complex network topology and difficult operation and maintenance, but also requires the user to manually configure a route, thus the operation is complex.
By applying the technical scheme provided by the embodiment of the invention, a cloud enterprise network is created, network instances in two areas of Beijing and Shanghai are respectively loaded on the cloud enterprise network, and dynamic route release and learning in each network instance are realized, so that a hybrid cloud network with enterprise scale and communication capability is easily built.
Referring to fig. 5, a system architecture diagram of a cloud network according to an embodiment of the present invention is provided. The cloud network illustrated in fig. 5 includes a cloud enterprise network, two or more network instances.
Any network instance is loaded to the cloud enterprise network, and routes in the network instance are issued to the cloud enterprise network based on a preset route management strategy;
and the cloud enterprise network propagates the route which is issued by any network instance into the cloud enterprise network to other network instances, so that the route which is issued by any network instance into the cloud enterprise network is learned by any network instance into the network instance.
In a possible implementation manner, the cloud enterprise network includes at least one cloud enterprise network management domain (not shown in the figure), a virtual tunnel is established between the cloud enterprise network management domain and a network instance in a corresponding area, where different cloud enterprise network management domains correspond to different areas, and where the cloud enterprise network includes two or more cloud enterprise network management domains, the two or more cloud enterprise network management domains are interconnected in pairs.
