Description
Technical Field
The invention relates to the technical field of computers, in particular to a disaster recovery method and a disaster recovery device for a hybrid cloud private line access network.
Background
In the current cloud computing network products, the private line is basically a product which all large-scale cloud computing manufacturers must provide and is used for realizing multi-cloud access. The cloud computing technology combining the public cloud platform and the private cloud platform is called as a hybrid cloud, at present, more and more enterprises have two services of external service and internal service, the enterprises hope to apply the public cloud platform for cost saving during external service, and the enterprises hope to apply the private cloud platform for safety during internal service, so the hybrid cloud is more and more popular.
As shown in fig. 1, fig. 1 is a network scheme for a cloud computing manufacturer to implement a private access, where a virtual machine traffic first passes through a hybrid cloud gateway to reach a private switch, an overlay network is provided between a host and the private switch, and the private switch is implemented by using a hardware network device (non-x 86 server). Then, a private line is inserted into another Internet Data Center (IDC) (or network) at the private line switch. Because the private line is shared by a certain client, the message is directly sent to the opposite terminal network through the physical private line without being realized through a tunnel technology.
The high availability of the private line is generally realized by accessing a plurality of physical lines, and each physical line is accessed to a different private line switch, so that the network connectivity is still ensured in case of any link failure.
As shown in fig. 2, the cloud environment is connected to two physical private lines and an opposite network through two private line switches, and the two private line switches are also directly connected to each other. All network segments destined to the opposite terminal network are configured with two routes, one next hop is an Internet Protocol (IP) address (high priority) of the opposite terminal network, and the next hop of the other route reaches the other private line switch (low priority) through the other line. A Bidirectional Forwarding Detection (BFD) protocol or a Network Quality Analysis (NQA) protocol is run between the private branch exchange and the access device of the opposite end to detect the link Quality. If the line fails (for example, the line is dug down by a construction team), the link is detected to be disconnected, the route is cancelled, the message is sent to other private line switches through the route with low priority configured before, and the other private line switches use other lines to send to the opposite terminal network.
In the above scheme, a cloud manufacturer accesses a plurality of physical lines through a plurality of private line switches, and then configures a backup route to a link directly connected to the private line switch to realize disaster recovery of the private line. There is no problem in the scenario of two or three private line switches, but when there are more private line switches and private line lines, the network becomes particularly complex and unmanageable.
As shown in fig. 3, if a customer needs to access multiple physical lines and a hybrid cloud needs to provide access to multiple devices, a network topology between multiple switches is very cluttered, and each private switch in fig. 3 needs to make a backup route for other private switches in addition to setting a next hop of a route with the highest priority as an opposite-end network, so as to avoid network interruption when a line fails. Even in the simplest approach, it is necessary to configure backup routes to other switches on each switch to prevent line failures.
If the customer needs to add a physical private line and then use a new private line switch to carry the load, the new switch needs to be configured with routes to other switches and needs a new connection route (green line). The configuration is complex and the network is overstaffed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The embodiment of the invention can move the actions of canceling or taking effect of the route and the like to the hybrid cloud gateway, avoids configuring an excessively complex network on a special line switch for accessing an opposite terminal network, reduces the wiring frequency of a machine room on one hand, and is simple and very easy to manage the special line switch on the other hand. As an example, as shown in fig. 4, in a service scenario, a cloud environment (which may include multiple computing nodes) is connected to an opposite-end network through three private-line switches, three equivalent routes are configured on a hybrid cloud gateway (connected to the cloud environment), next hops are three private-line switches respectively used for accessing to the opposite-end network, and in the case of no exception, a packet going back and forth in the service scenario is loaded through the three lines.
In addition, in the embodiment of the invention, the link quality of the special line corresponding to each special line switch is detected by means of a middleware, the link quality condition is synchronized to the process of the middleware, once the link failure is detected, the route is adjusted on the hybrid cloud gateway, and the flow corresponding to the failed link is switched to other equivalent routes without failure. As an example, as shown in fig. 5, a monitoring device (middleware) is added in the network shown in fig. 4 to monitor the link status, and if a certain line is disconnected or a certain private switch goes down, the monitoring device can quickly monitor and then feed back to the hybrid cloud gateway, so that the hybrid cloud gateway deletes the corresponding route, as shown in fig. 6, a BFD protocol may be configured on the private switch, and BGP may be configured between the private switch and gobgp (an example of middleware). If the leftmost private line is interrupted for some reason, the BFD protocol on the private line switch can detect the link interruption, then the private line switch cancels the route, after the route of the private line switch is cancelled, because BGP exists between the private line switch and the gobgp, the operation of the route cancellation is synchronized into the gobgp through BGP information, then the gobgp calls an interface of the hybrid cloud gateway after receiving the BGP information, and cancels the route corresponding to the interrupted link on the hybrid cloud gateway.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 7 is a schematic flow chart of a disaster recovery method for a hybrid cloud dedicated access network according to an embodiment of the present invention. The private access network comprises a plurality of private links between the hybrid cloud gateway and the opposite-end network, an equivalent routing list (for example, an equivalent routing list '10.20.0.0/24 gw1.1.1.1; 10.20.0.0/24 gw1.1.1.2; 10.20.0.0/24 gw1.1.1.3' in the hybrid cloud gateway in fig. 4) is configured on the hybrid cloud gateway, each equivalent route in the equivalent routing list corresponds to a private link, and in addition, the equivalent routing list can comprise a plurality of private links, each corresponding to a user; the method can be applied to a monitoring device, which is an intermediary, e.g. the gobgp shown in fig. 6. As shown in fig. 7, the method may specifically include:
step S710, monitoring link states of a plurality of private links;
the link status of each private link may be monitored in a variety of ways. For example, link states of a plurality of dedicated links may be monitored based on the BFD protocol. As an example, the monitoring device may establish BGP-based peers with the private switches of each private link, respectively; each private line switch can monitor the link state of the corresponding private line link based on a BFD protocol; the monitoring device may detect the link status based on the BFD protocol via the BGP-based synchronous private line switch.
In addition, after the monitoring device establishes the peer based on the BGP with the private line switch of each private line link, the monitoring device may also perform route learning on each peer based on the BGP to determine an equivalent route corresponding to each private line link. As shown in connection with fig. 5, the monitoring device may be implemented using a gobgp open source project, and the monitoring device may be gobgp. BGP peers (peers) are established using gobgp and associated private line switches. Under normal network conditions, all three private switches in fig. 5 are configured and effect the next hop to peer network route (10.20.0.0/24). Then gobgp can learn 10.20.0.0/24 through three peers and can recognize that there are three paths, respectively three private line switches (1.1.1.1, 1.1.1.2 and 1.1.1.3). If one of the three private links is broken, the gobgp can learn the corresponding route change through BGP.
Step S720, when it is monitored that a first private link in the plurality of private links has a fault, sending an equivalent routing withdrawal request of the first private link to the hybrid cloud gateway, so that the hybrid cloud gateway withdraws the equivalent routing of the first private link in an equivalent routing list.
As shown in fig. 6, if the dedicated link corresponding to the dedicated switch (1.1.1.3) is interrupted for some reason, the BFD on the dedicated switch can detect the link interruption and then withdraw the route. After the route is withdrawn, because BGP exists between the private line switch and the gobgp, the route withdrawing operation is synchronized into the gobgp. After receiving the message of BGP (the next withdrawal of the withdrawal 10.20.0.0/24 is 1.1.1.3 withdrawal), the gobgp calls an interface of the hybrid cloud gateway and withdraws the route corresponding to the interrupted link in the hybrid cloud gateway.
And the hybrid cloud gateway transmits the service data of the user based on the equivalent routing list.
In some embodiments, if the broken link is repaired, BFD may enable the relevant route to take effect, which may be synchronized to gobgp by BGP, which recalls adding the route to the interface of the hybrid cloud gateway. As an example, the method may further comprise the steps of: when the second special line link in the special line links is monitored to be effective, an equivalent route effective request of the second special line link is sent to the hybrid cloud gateway, so that the hybrid cloud gateway adds the equivalent route of the first special line link in an equivalent route list.
The embodiment of the invention monitors the link states of a plurality of special links; when the fact that a first special line link in the special line links breaks down is monitored, an equivalent route withdrawal request of the first special line link is sent to the hybrid cloud gateway, and therefore the hybrid cloud gateway withdraws the equivalent route of the first special line link in an equivalent route list. Therefore, routing adjustment can be performed on the hybrid cloud gateway, too many network contents are prevented from being configured on the private line switch, network wiring of a machine room is simplified, configuration difficulty of the disaster recovery method is reduced, and usability of the disaster recovery method is improved.
Fig. 8 is a schematic flow chart of another disaster recovery method for a hybrid cloud dedicated access network according to an embodiment of the present invention. The private access network comprises a plurality of private links between the hybrid cloud gateway and the opposite terminal network; the method may be applied to a hybrid cloud gateway, as shown in fig. 8, and may include the following steps:
s810, receiving an equivalent route withdrawal request of a first private link in the multiple private links sent by the monitoring device.
The hybrid cloud gateway is configured with an equivalent routing list, and each equivalent routing in the equivalent routing list corresponds to a private link.
As shown in fig. 6, if a dedicated link corresponding to the dedicated switch (1.1.1.3) is interrupted for some reason, the BFD on the dedicated switch can detect the link interruption, and after receiving a BGP message (the next route of 10.20.0.0/24 is 1.1.1.3 withdrawal), the gobgp calls an interface of the hybrid cloud gateway and sends an equivalent route (the next route of 10.20.0.0/24 is 1.1.1.3) withdrawal request of the first dedicated link to the hybrid cloud gateway.
And S820, withdrawing the equivalent route of the first private link in the equivalent route list so as to distribute the hybrid cloud private line service based on the equivalent route list after withdrawing the equivalent route of the first private link.
In some embodiments, if the broken link is repaired, validation of the route may be synchronized to gobgp by BGP, which recalls the interface of the hybrid cloud gateway to add the route. As an example, the method further comprises:
step 1), receiving an equivalent route validation request of a second special line link in a plurality of special line links sent by monitoring equipment;
and step 2), adding the equivalent route of the second special line link into the equivalent route list so as to distribute the mixed cloud special line service based on the equivalent route list after the equivalent route of the second special line link is added.
