Some terms related to the embodiments of the present invention will be described:
cloud special line: the method is used for constructing a high-speed, low-delay, stable and safe exclusive connection channel between the user local data center and the virtual private cloud (Virtual Private Cloud, VPC) on the cloud. And the data service of the VPC and the user data center on the cloud can be communicated through the cloud private line. The user can connect the user network, the data center and the host management area on the user side to the VPC private line connection on the cloud through the cloud private line, and enjoy the data network with high performance, low delay and safety.
Region (Region): areas are also called resource pools, nodes, refer to physical locations where cloud servers are deployed, e.g., shanghai, guizhou, beijing, guangzhou, etc., all belong to different areas.
Available area (Available area): also called AZ, refers to a geographical area where power and networks are independent of each other, typically an independent physical machine room, in the same area, so that the independence of the available areas can be ensured. Typically, there are multiple available areas in a region, and one available area fails without affecting other available areas in the same region. And a plurality of available areas in the same area are directly communicated with each other through an intranet, and the intranets among different areas are not communicated with each other. Wherein the available area is provided with computing resources and storage resources for processing various services.
In the embodiment of the invention, on the premise of ensuring the safety, stability and high speed of the cloud private line service, the adaptation of the high availability characteristic of the multi-availability area AZ resource pool deployment is very important. The multi-availability-zone AZ cloud private line control management system mainly realizes the adaptation of cloud private line service to multi-AZ application scenes by the following three aspects: 1. the special line is accessed to the cross-available area AZ combination management of the switch; 2. a multi-level high availability design; 3. generic standardized device-independent routing policies.
Referring to fig. 1, a step flow chart of a communication path selection method provided in an embodiment of the present invention is shown, and the step flow chart relates to a network element device, where the network element device includes a user side device, virtual border routers of different available areas, and virtual gateways of a virtual private cloud, the user side device is connected to the virtual border routers of different available areas through different physical private lines, and the virtual border routers are connected to the virtual gateways, and specifically may include the following steps:
In the above-mentioned communication path selection method, network element devices such as user side devices, virtual boundary routers of different available areas, virtual gateways of virtual private clouds and the like are involved, the user side devices are respectively connected to the virtual boundary routers of different available areas through different physical private lines, the virtual boundary routers are respectively connected to the virtual gateways, when cloud private line service from the user side devices to the virtual private clouds is realized, the connectivity between the network element devices is detected, the routing configuration is adjusted according to the connectivity between the network element devices, and then the communication path from the user side devices to the virtual gateways is selected according to the routing configuration. The embodiment of the invention uses the general standardized device-independent communication path routing strategy to select the communication path from the user side device to the virtual private cloud, provides safe, rapid and highly available cloud private line service for enterprise users, and ensures the highly available characteristic of the multi-available area AZ.
Next, a method of selecting a communication path in the present exemplary embodiment will be further described.
In step 101, connectivity between the network element devices is detected.
Referring to fig. 2, a schematic diagram of a network architecture provided by an embodiment of the present invention includes a customer premise equipment CE, two virtual border routers VBR (VBR 1 and VBR 2) corresponding to two available areas AZ (AZ 1 and AZ 2) respectively, a virtual gateway VGW of a virtual private cloud VPC (the virtual gateway VGW is an access router of a cloud private line), and other network element devices. According to the user demand, the user of the user side equipment CE is pulled to the physical private lines of the two available areas AZ, the private line POP switches in the available areas AZ are respectively accessed, the two virtual boundary routers VBR are corresponding, and then the two virtual boundary routers VBR are respectively connected to the virtual private cloud VPC through the virtual gateway VGW of the virtual private cloud VPC.
In a specific implementation, network element devices are not always connected for various reasons, for example, there may be a case that a user side device CE can only be connected to a virtual border router VBR1 or can only be connected to a user side device CE through a virtual border router VBR2, so in the embodiment of the present invention, when implementing a cloud private line service from the user side device CE to a virtual private cloud VPC, the connectivity between the network element devices may be detected first, and then, a communication path from the user side device CE to the virtual private cloud VPC may be selected according to the connectivity between the network element devices.
In an optional embodiment of the present invention, the step 101 of detecting connectivity between the network element devices may include the following steps:
detecting connectivity from the virtual border router to the user side device, and detecting connectivity from the virtual border router to the virtual gateway.
In the embodiment of the invention, the cloud dedicated line control system starts a link detection function, and the communication between the virtual gateway VGW and the user side equipment UE is detected from the virtual boundary router VBR. For example, referring to fig. 2, connectivity of the virtual border router VBR1 to the virtual gateway VGW, the virtual border router VBR2 to the virtual gateway VGW, the virtual border router VBR1 to the user side device UE, and the virtual border router VBR2 to the user side device UE may be detected.
In step 102, adjusting routing configuration according to connectivity between the network element devices; the routing configuration at least comprises whether the network element devices are communicated or not.
In an optional embodiment of the present invention, the step 102 of adjusting a routing configuration according to the connectivity between the network element devices may include the following steps:
and if the communication from the virtual boundary router to the virtual gateway is detected to be the detection failure, configuring the route from the virtual boundary router to the virtual gateway as non-communication in the route configuration.
And if the communication from the virtual boundary router to the user side equipment is detected to be the detection failure, configuring the routes from the virtual boundary router to the user side equipment and the virtual boundary router to the virtual gateway as non-communication in the route configuration.
In the embodiment of the invention, a cloud private line control system (private line control) initiates a link detection function, and detection from a Virtual Border Router (VBR) to user side equipment (CE) and Virtual Gateway (VGW) equipment is initiated. Specifically, referring to fig. 3, for a schematic diagram of link probing provided in an embodiment of the present invention, referring to the schematic diagram above in fig. 3, if path probing from the virtual border router VBR to the user side device CE fails, the dedicated management and control sends BGP neighbor disable (not connected) to the user side device CE on the virtual border router VBR, and notifies the cloud management and control to delete the routing configuration to the virtual border router VBR on the virtual gateway VGW. Referring to the schematic diagram below in fig. 3, if the path probing of the virtual border router VBR to the virtual gateway VGW fails, the dedicated management control will disable BGP neighbors on the virtual border router VBR to the customer side equipment CE.
In step 103, a communication path from the user side device to the virtual gateway is selected according to the routing configuration.
In the embodiment of the invention, after the detection of the connectivity between the network element devices is completed and the routing configuration is completed, when the cloud private line service is performed, the communication path from the user side device CE to the virtual private cloud VPC can be determined according to the connected network element devices. For example, assuming that the customer side device CE is not connected to the virtual border router VBR1, the virtual gateway VGW may be selected to route from the customer side device CE to the virtual border router VBR2 and then to the virtual private cloud VPC through the virtual border router VBR 2.
In an alternative embodiment of the present invention, the step 103 of selecting a communication path from the user side device to the virtual gateway according to the routing configuration may include the steps of:
acquiring a link strategy; the link policy is a link policy of a communication path from the user side device to the virtual private cloud;
and selecting a communication path from the user side equipment to the virtual gateway according to the link strategy and the routing configuration.
In the embodiment of the invention, various link strategies are set, and can comprise a load balancing strategy and a main and standby line strategy. Illustratively, the load balancing policy is an ECMP (equal cost multi-path routing, equal CostMulti Path) protocol that configures two physical dedicated lines on the customer premise equipment CE, and the ECMP protocol can implement load balancing of the network. The primary-standby line policy refers to the priority of the designated physical dedicated line, and the corresponding priority is configured when the route is configured on the customer premise equipment CE and the virtual border router VBR, for example, the priority of the customer premise equipment CE and the virtual border router VBR1 may be set to be higher than the priority of the customer premise equipment CE and the virtual border router VBR2, and the priority of the virtual border router VBR2 to the virtual gateway VGW is higher than the priority of the virtual border router VBR1 to the virtual gateway VGW. Of course, in addition to the load balancing policy and the active/standby line policy described above, other link policies may be set according to actual service requirements, which is not limited in the embodiment of the present invention.
In an optional embodiment of the present invention, the selecting, in step 103, a communication path from the user side device to the virtual gateway according to the link policy and the routing configuration may include:
when the link policy is a load balancing policy, the priorities from the user side device to the virtual border router and from the virtual border router to the virtual gateway are the same, and if the network element devices are all communicated according to the routing configuration, a communication path from the user side device to the virtual gateway is selected according to the load balancing condition.
When the link policy is a primary and backup line policy, the priorities from the user side device to the virtual border router and from the virtual border router to the virtual gateway are different, and if the network element devices are determined to be communicated according to the routing configuration, a communication path from the user side device to the virtual gateway is selected according to the priorities from the user side device to the virtual gateway.
In the embodiment of the invention, if the link policy from the user side device to the virtual border router VBR is a load balancing policy, the static routing priorities from the virtual border router VBR to the virtual gateway VGW are configured to be the same, i.e. under the same condition, the communication paths can be randomly selected; if the link policy from the user side device to the virtual border router VBR is the primary/standby line policy, the static routing priority from the virtual border router VBR to the virtual gateway VGW is configured to be different, for example, a primary route and a standby route may be set, and the primary route is preferably selected as the communication path under the condition that the primary route and the standby route are all connected.
For example, referring to the left schematic diagram of fig. 2, the network architecture uses a link policy that is a primary-backup line policy, where the primary line priority is greater than the backup line, where the primary line is a communication path from the user side device CE to the virtual border router VBR1, from the virtual border router VBR1 to the virtual gateway VGW, and from the virtual gateway VGW to the virtual border router VBR1, from the virtual border router VBR1 to the user side device CE, and the backup line is a communication path from the user side device CE to the virtual border router VBR2, from the virtual border router VBR2 to the virtual gateway VGW, and from the virtual gateway VGW to the virtual border router VBR2, from the virtual border router VBR2 to the user side device CE, and, assuming that network element devices in the network architecture are all in communication, from the user side device CE to the virtual border router VBR1, from the virtual border router VBR1 to the virtual gateway VGW may be preferentially selected, and from the virtual border router VBR1 to the virtual border router VGW may be selected.
Referring to the right schematic diagram of fig. 2, the link policy used by the network architecture is a load balancing policy, where priorities from the user side device CE to the virtual border router VBR1 and the virtual border router VBR2, to the virtual gateway VGW, the virtual border router VBR2 to the virtual gateway VGW, the virtual gateway VGW to the virtual border router VBR1 and the virtual border router VBR2, the virtual border router VBR1 to the user side device CE, and the virtual border router VBR2 to the user side device CE are the same, and if network element devices in the network architecture are all connected, a communication path from the user side device CE to the virtual gateway VGW may be selected according to the load balancing state of the user side device CE.
The embodiment of the invention aims to solve the problem that the cloud private line service of the enterprise user adapts to the high availability characteristic of a plurality of AZ resource pools, and the cloud private line control management system provides safe, rapid and high-availability cloud private line service for the enterprise user by supporting the combination management capability of the cross AZ private line switch at the level of the resource pool and using a universal standardized device-independent routing strategy in a fully-automatic opening mode.
