Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
In the related technology, in a dual DC-vbars resource pool deployment manner, NFVO is deployed in a data center in a cluster manner, and different data centers carry different services of users accessed by HJSW, thereby realizing load balancing.
Fig. 1a shows a schematic diagram of a dual DC networking in the related art. As shown in fig. 1a, NFVO1 and NFVO2 represent NFVO within NFVO cluster, DC1 and DC2 represent data centers, POOL-GW1 and POOL-GW2 represent resource POOL gateways, and HJSW1 and HJSW2 represent aggregation switches.
As shown in fig. 1a, NFVO1 and NFVO2 are disposed within DC1 and DC2, respectively. A VXLAN tunnel from POOL-GW1 to HJSW1 and a VXLAN tunnel from POOL-GW1 to service vbars in DC1 are respectively configured on POOL-GW1 deployed inside DC 1. The service vbars of the DC1 may be used to carry the service of the user accessed by the HJSW 1.
Fig. 1b shows a schematic configuration diagram of VSI on the POOL-GW1 based on fig. 1a, where DC1_1 is the identifier of the VSI on the POOL-GW1, VXLAN1 is the VXLAN identifier corresponding to the VSI, tunnel11 may represent VXLAN tunnels from the POOL-GW1 to HJSW1, and tunnel21 may represent VXLAN tunnels from the POOL-GW1 to the service vbars inside DC 1.
Fig. 1c shows a schematic diagram of the configuration of VSI on HJSW1 based on fig. 1 a. Wherein, DC1 is the identifier of VSI on HJSW1, VXLAN1 is the VXLAN identifier corresponding to the VSI, and tunnel1 can represent the VXLAN tunnel from HJSW1 to POOL-GW 1.
Through a VXLAN tunnel between POOL-GW1 and HJSW1 and a VXLAN tunnel between POOL-GW1 and a service vBRAS inside DC1, the DC1 can bear the service of a user accessed by HJSW 1. DC2 in fig. 1a may refer to DC1, the configuration of VSI on POOL-GW2 may refer to POOL-GW1, and the configuration of VSI on HJSW2 may refer to HJSW1, which is not described herein.
Thus, in the related art, DC1 carries traffic of users accessed by HJSW1, and DC2 carries traffic of users accessed by HJSW 2. If the DC1 is abnormal, the service interruption of the user accessed by the HJSW1 is caused; if the DC2 is abnormal, the service of the user accessed by the HJSW2 is interrupted. Therefore, in the related art, the reliability of the data center is poor.
In order to make those skilled in the art better understand the technical solutions in the embodiments of the present disclosure, some technical terms related to the embodiments of the present disclosure are briefly described below.
A resource pool gateway represents a gateway device of a vbars resource pool consisting of a plurality of vbars.
The aggregation switch carried by the first data center represents an aggregation switch for carrying traffic of a user accessing the first data center. In this way, the first data center can carry the traffic of the user accessed by the aggregation switch.
The aggregation switch carried by the second data center represents an aggregation switch for carrying traffic of users accessing the second data center. In this way, the second data center can carry the traffic of the users accessed by the aggregation switch.
Fig. 2a shows a schematic diagram of a dual DC networking according to an embodiment of the present disclosure. As shown in fig. 2a, the dual DC networking of the embodiment of the present disclosure adds backup vbars in DC1 and DC2, and adds VXLAN tunnel between the POOL-GW1 and the backup vbars of DC1, and VXLAN tunnel between the POOL-GW1 and the HJSW2, respectively, on the basis of the dual DC networking shown in fig. 1 a. Accordingly, a VXLAN tunnel between POOL-GW2 and HJSW1 is added, as well as a VXLAN tunnel between POOL-GW2 and the backup vbars of DC 2. The backup vBRAS can be created through the NFVO cluster, and the backup vBRAS does not carry services under normal conditions.
It should be noted that the DC2 shown in fig. 2a can carry the services of users accessed by multiple aggregation switches, that is, the DC2 can carry not only the services of users accessed by the HJSW2, but also the DC2 can carry the services of users accessed by other aggregation switches. Wherein each aggregation switch may correspond to a first VXLAN tunnel and a second VXLAN tunnel. In the embodiment of the present disclosure, the second data center DC2 is used to carry the service of the user accessed by one aggregation switch (for example, HJSW2 shown in fig. 2 a), and the embodiment of the present disclosure is also applicable to the case where the second data center DC2 carries the service of the user accessed by multiple aggregation switches.
For ease of description, the method of the present invention is described based on a dual DC networking as shown in fig. 2a, although the present disclosure is equally applicable to a networking where there are multiple DCs. In the embodiment of the present disclosure, DC1 shown in fig. 2a is taken as a first data center, DC2 is taken as a second data center, POOL-GW1 is taken as a first resource POOL gateway, HJSW2 is a convergence switch carried by the second data center, a VXLAN tunnel between POOL-GW1 and HJSW2 is taken as a first VXLAN tunnel, and a VXLAN tunnel between POOL-GW1 and a backup vBRAS of DC1 is taken as a second VXLAN tunnel.
FIG. 3 shows a flow diagram of a data center exception handling method according to an embodiment of the present disclosure. The data center exception handling method may be applied to an NFVO cluster, where NFVOs within the NFVO cluster are deployed in data centers of a dual-DC networking shown in fig. 2a, where the data centers of the dual-DC networking include a first data center (DC 1 shown in fig. 2 a) and a second data center (DC 2 shown in fig. 2 a). As shown in fig. 3, the data center exception handling method may include:
step S11, the status of each data center is monitored.
Step S12, when it is monitored that the second data center is in an abnormal state, sending an interface start command to a first resource pool gateway deployed inside the first data center, so as to start a first VXLAN tunnel established between the first resource pool gateway and a convergence switch carried by the second data center, and start a second VXLAN tunnel established between the first resource pool gateway and a backup vBRAS inside the first data center, so that the first data center carries a service of a user accessed through the convergence switch.
In the embodiment of the present disclosure, the state of the data center is monitored by the NFVO cluster, and when the data center is abnormal, the VXLAN tunnel of the resource pool gateway of the abnormal data center is switched to the VXLAN tunnel of the resource pool gateway of the backup data center, so that the backup data center can bear the service borne by the abnormal data center, thereby avoiding interruption of the service borne by the abnormal data center, and improving reliability of the data center.
The NFVOs are deployed in the data centers in a cluster mode, and the NFVO cluster can monitor the state of each data center through the NFVOs deployed in each data center. The state of the data center includes a normal state and an abnormal state. The normal state may indicate that the data center is working normally, and the data center may normally carry the service of the user accessed by the corresponding aggregation switch. The abnormal state may indicate that the data center fails to normally carry the service of the user accessed by the corresponding aggregation switch. For example, when a first data center and a second data center are included in a dual DC networking, the NFVO cluster may monitor the status of the first data center through the NFVO (NFVO 1 shown in fig. 2 a) deployed in the first data center, and monitor the status of the second data center through the NFVO (NFVO 2 shown in fig. 2 a) deployed in the second data center.
In this embodiment of the present disclosure, the second data center may be any one data center, and the first data center may be any one data center, where the first data center may also serve as a backup data center of the second data center while bearing a service of a user corresponding to the access of the aggregation switch, so as to bear a service originally borne by the second data center when the second data center is abnormal. The NFVO cluster may create a backup vBRAS inside a first data center, establish a first VXLAN tunnel between the first resource pool gateway and a convergence switch carried by a second data center, and establish a second VXLAN tunnel between the first resource pool gateway and the backup vBRAS inside the first data center.
In a possible implementation manner, the second data center includes a second resource pool gateway and a service vbars, a third VXLAN tunnel is established between the second resource pool gateway and a convergence switch carried by the second data center, and a fourth VXLAN tunnel is established between the second resource pool gateway and the service vbars in the second data center. A connection between the aggregation switch carried by the second data center and the service vbars in the second data center may be established through the third VXLAN tunnel and the fourth VXLAN tunnel. In this way, the user equipment accessed by the aggregation switch carried by the second data center may send the service packet to the service vbars in the second data center.
The first VXLAN tunnel may represent a VXLAN tunnel between the first resource pool gateway and a convergence switch carried by the second data center, and the second VXLAN tunnel may represent a VXLAN tunnel between the first resource pool gateway and a backup vBRAS inside the first data center. A backup vbars in a first data center refers to a backup of a service vbars in a second data center.
A connection between the aggregation switch carried by the second data center and the backup vbars inside the first data center can be established through the first VXLAN tunnel and the second VXLAN tunnel.
In this way, the aggregation switch carried by the second data center is connected to both the backup vbars in the first data center and the service vbars in the second data center.
The NFVO cluster may close the first VXLAN tunnel and the second VXLAN tunnel while the second data center is in a normal state. Therefore, when the second data center is in a normal state, the user equipment accessed by the aggregation switch carried by the second data center can send the service message to the service vBRAS inside the second data center, but cannot send the service message to the backup vBRAS inside the first data center.
In a possible implementation manner, the NFVO cluster may set a first VSI corresponding to a first VXLAN tunnel and a second VXLAN tunnel in a first resource pool gateway deployed inside a second data center to a closed state, that is, a shutdown state. When the first VSI is in a closed state, although the user equipment accessed by the aggregation switch carried by the second data center may send the service packet to the first resource pool gateway, the service packet cannot be sent to the backup vbars inside the first data center.
In one example, fig. 2b shows a schematic configuration diagram based on VSI on POOL-GW1 of fig. 2a in an embodiment of the present disclosure. As shown in fig. 2b, DC2_1 is the identity of the VSI on the POOL-GW 1; VXLAN3 is the VXLAN identifier corresponding to the VSI; tunnel13 may represent the VXLAN tunnel from POOL-GW1 to HJSW2, i.e., the first VXLAN tunnel; tunnel22 may represent a tunnel from POOL-GW1 to a backup vbars deployed inside DC1, i.e., a second VXLAN tunnel. When DC1 is in a normal state, DC2_1 corresponding to tunnel13 and tunnel22 is in a shutdown state, that is, the first VSI corresponding to the first VXLAN tunnel and the second VXLAN tunnel is in a closed state. Fig. 2c shows a schematic configuration diagram of a VSI on HJSW1 based on fig. 2a in an embodiment of the present disclosure. Wherein, DC1 is the identifier of VSI on HJSW1, VXLAN1 is the VXLAN identifier corresponding to the VSI, and tunnel2 can represent the VXLAN tunnel from HJSW1 to POOL-GW 2. Reference may be made to HJSW1 for HJSW2, which is not described here.
When the second data center is in an abnormal state, it indicates that the second data center may have a fault, and the second data center may not be able to continue to carry the service of the user originally accessed by the aggregation switch carried in the second data, thereby causing the service interruption. The NFVO cluster may start a backup data center of the second data center when it is monitored that the second data center is in an abnormal state, so that the backup data center carries a service of a user, which is originally carried by the aggregation switch carried by the second data center and accessed by the aggregation switch.
In the embodiment of the present disclosure, a first data center is taken as a backup data center of a second data center as an example. The NFVO cluster may send an interface start command to a first resource pool gateway deployed in the first data center when it is monitored that the second data center is in an abnormal state. The interface open command may indicate opening of the first VXLAN tunnel and opening of the second VXLAN tunnel. After the first VXLAN tunnel and the second VXLAN tunnel are opened, the user equipment accessed by the aggregation switch carried by the second data center can send the service message to the first resource pool gateway in the first data center, and then send the service message to the backup vbars in the first data center, so that the service of the user accessed by the aggregation switch originally carried by the second data center can be normally processed.
In a possible implementation manner, the interface start command may be an undo shutdown command, and the interface start command may instruct the first resource pool gateway to start the first VSI corresponding to the first VXLAN tunnel and the second VXLAN tunnel. And after receiving the interface opening command, the first resource pool gateway sets the first VSI to be in an opening state. When the first VSI is in the on state, the user equipment accessed by the aggregation switch carried by the second data center may send the service packet to the first resource pool gateway, and then to the backup vbars in the first data center.
Application example
As shown in fig. 2a, the NFVO cluster may monitor the status of DC1 and DC 2.
When the DC2 is in a normal state, the HJSW2 can access the service vbars deployed inside the DC2 through the third VXLAN tunnel and the fourth VXLAN tunnel, so that the DC2 can bear the service of the user accessed by the HJSW 2.
When the second data center DC2 is monitored to be in an abnormal state, the NFVO cluster may open the first VXLAN tunnel and the second VXLAN tunnel. At this time, the HJSW2 accesses the backup vbars of the first data center DC1 through the first VXLAN tunnel and the second VXLAN tunnel, so that the first data center DC2 carries the services of the user accessed by the HJSW 2.
In one possible implementation manner, when it is monitored that the second data center recovers to a normal state, the first VXLAN tunnel and the second VXLAN tunnel are closed. For example, the NFVO cluster may send a shutdowm instruction to the first resource pool gateway to close the first VSI.
The first data center is used as a backup data center of the second data center, and after the second data center is restored, the second data center can normally bear the originally-borne service of the user accessed by the aggregation switch. Therefore, the NFVO cluster can close the first VXLAN tunnel and the second VXLAN tunnel, so that the first data center does not bear the service of the user accessed by the aggregation switch originally borne by the second data center any more, and resources of the vbars resource pool are saved.
FIG. 4 shows a flow diagram of a data center exception handling method according to an embodiment of the present disclosure. As shown in fig. 4, the data center exception handling method may further include:
and step S13, establishing a session with a second resource pool gateway deployed in the second data center.
And step S14, acquiring the state of the session at intervals of a first time length.
Step S15, when the number of times that the session is in the unavailable state is greater than a number threshold, determining that the second data center is in an abnormal state.
When a resource pool gateway in the data center fails, the data center cannot bear the service of the aggregation switch access user. In this case, the NFVO cluster may determine that the data center is failed, i.e., the data center is in an abnormal state.
The NFVO cluster may establish a session with a second resource pool gateway. In one example, the NFVO2 deployed in the second data center in the NFVO cluster may establish a session with the second resource pool gateway through NETCONF (Network Configuration Protocol). The NFVO2 may obtain the state of the session once every first duration. When the number of times that the session is in the unavailable state is greater than the number threshold, indicating that the connection between the NFVO2 and the second resource pool gateway is abnormal, the NFVO2 may determine that the second resource pool gateway fails, and may further determine that the second data center is in an abnormal state.
The first duration and the number threshold may be set as needed, and the disclosure is not limited thereto.
In a possible implementation manner, the NFVO cluster may establish a session with the second resource pool gateway through a NETCONF protocol.
FIG. 5 shows a flow diagram of a data center exception handling method according to an embodiment of the present disclosure. As shown in fig. 5, the data center exception handling method may further include:
step S16, monitoring heartbeat messages of each NFVO in the cluster.
Step S17, if the heartbeat message sent by the NFVO corresponding to the second data center is not received in the cluster within the second duration, it is determined that the second data center is in an abnormal state.
In the embodiment of the present disclosure, the NFVO may monitor the status of other NFVOs in the cluster through inter-cluster heartbeat messages (e.g., ping). If the heartbeat message sent by the NFVO corresponding to the second data center is not received in the cluster within the second duration, the NFVO cluster may determine that the NFVO fails. At this time, the NFVO cluster cannot monitor the state of the resource pool gateway in the data center through the NFVO deployed in the data center, or the NFVO cluster cannot know the state information monitored by the NFVO deployed in the data center. Under the condition, the NFVO cluster determines that the second data center is in an abnormal state, so that the backup data center can be started, and the reliability of the data center is improved.
The second duration may be set as needed, and the disclosure is not limited thereto.
It should be noted that, in the dual-DC networking, the NFVO cluster may deploy the second data center as the same as the first data center, so that the second data center may also serve as a backup data center of the first data center while bearing the service of the user corresponding to the access of the aggregation switch, so as to bear the service originally borne by the first data center when the first data center is abnormal. The processing mode of the first data center for the occurrence of the abnormality may refer to the processing mode of the second data center for the occurrence of the abnormality in the embodiment of the present disclosure, and details are not described here.
