Description
Technical Field
The invention particularly relates to a dynamic disaster recovery method, a dynamic disaster recovery system, equipment, a medium and a mixed cloud system of PE equipment.
Background
In the context of cloud computing, hybrid cloud systems have become a new standard. The user connects the Private Cloud of the user to the public Cloud of the provider in a Private line hosting manner to perform mixed Cloud deployment, so that an internal Private Cloud network of the user and a Virtual Private Cloud (VPC) network on the public Cloud of the provider are opened.
Provider Edge (PE) devices, as core forwarding nodes of the hybrid cloud system, must support the function of disaster recovery. Conventional PE devices are typically deployed by way of a Link Aggregation Group (LAG), physically stacking two PE devices together, presenting one PE device out, and broadcasting the same virtual IP address to provide services.
This approach takes advantage of the physical properties of the PE devices to bring about system stability, but has considerable disadvantages. First, the stacking method has certain technical defects, which cause additional instability. Secondly, the stacking technology needs to physically connect the PE equipment, and cross-region disaster recovery cannot be realized. In addition, by publishing the same virtual IP address to provide services, great inflexibility is introduced.

Detailed Description
In order to make the purpose and technical solution of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
In accordance with the present invention, there is provided an embodiment of a dynamic disaster recovery method for PE devices, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
According to the present invention, an embodiment of a dynamic disaster recovery system of a PE device is provided, and it should be noted that the system embodiment may be included in a hybrid cloud system. Fig. 1 is a block diagram of a hybrid cloud system according to the present invention. As shown in fig. 1, hybrid cloud system 100 includes a public cloud 102 and a private cloud 104, and hybrid cloud system 100 also includes a dynamic disaster recovery system 106 of PE devices between public cloud 102 and private cloud 104. Public cloud 102 is provided by a vendor and may include one or more virtual machines. Private cloud 104 is provided by a user. Dynamic disaster recovery system 106 of PE devices can connect public cloud 102 and private cloud 104 for hybrid cloud deployment.
Fig. 2 is a block diagram of a dynamic disaster recovery system of PE devices according to the present invention. Fig. 3 is another block diagram of a dynamic disaster recovery system of PE devices according to the present invention. As shown in fig. 2 and 3, dynamic disaster recovery system 200/300 of PE devices includes a first PE device 202, a first Customer Edge (CE) device 204, a second PE device 206, a second CE device 208, and a gateway 210. As shown in fig. 2, first CE device 204 and second CE device 208 are connected to private cloud 104, gateway 210 is connected to public cloud 102, and first PE device 202 and second PE device 206, serving as core forwarding nodes, are connected to gateway 210 and are connected to first CE device 204 and second CE device 208, respectively. Fig. 4 is a flow chart of a dynamic disaster recovery method of a PE device according to the present invention. This is explained in detail below with reference to fig. 2 to 4.
At step S402, first PE device 202 receives first routing information from first CE device 204, and second PE device 206 receives second routing information from second CE device 208.
As shown in fig. 3, the first PE device 202 and the second PE device 206 are two completely independent PE devices (e.g., PE switches), and there is no physical connection between the first PE device 202 and the second PE device 206. Additionally, first PE device 202 and second PE device 206 each issue a completely independent virtual IP address to provide services, e.g., the virtual IP address of first PE device 202 may be 10.0.0.7 and the virtual IP address of second PE device 206 may be 10.0.0.8.
Wherein a Tunnel (Tunnel) is established between the first PE device 202 and the second PE device 206, as shown in fig. 3.
Through step S402, no additional physical connection is required between the first PE device 202 and the second PE device 206, and the deployment may be performed across regions.
At step S404, the first PE device 202 advertises the first routing information to the second PE device 206, and the second PE device 206 advertises the second routing information to the first PE device 202.
Wherein the first PE device 202 and the second PE device 206 advertise the first routing information and the second routing information to each other using an internal Border Gateway protocol (ibgp) Over Tunnel.
Through step S404, the traffic transfer disaster tolerance between the first PE device 202 and the second PE device 206 can be realized.
At step S406, the gateway 210 receives the first routing information from the first PE device 202, and the gateway 210 receives the second routing information from the second PE device 206.
Wherein the gateway 210 sends the first packet information to the first PE device 202 after receiving the first routing information from the first PE device 202, and the gateway 210 sends the second packet information to the second PE device 206 after receiving the second routing information from the second PE device 206.
Among them, the gateway 210 uses a Tunnel Equal Cost multi path (Equal-Cost multi path) protocol.
Through step S406, the gateway 210 supports multi-hop routing, and may implement traffic scheduling.
At step S408, when the gateway 210 does not receive the first routing information from the first PE device 202, the gateway 210 is switched to receive the first routing information from the second PE device 206, and when the gateway 210 does not receive the second routing information from the second PE device 206, the gateway 210 is switched to receive the second routing information from the first PE device 202.
For example, when a link between a first PE device 202 and a first CE device 204 fails and/or the first PE device 202 is down, the gateway 210 does not receive first routing information from the first PE device 202, and when a link between a second PE device 206 and a second CE device 208 fails and/or the second PE device 206 is down, the gateway 210 does not receive second routing information from the second PE device 206.
Wherein the gateway 210 sends the first packet information to the second PE device 206 after the gateway 210 is switched to receive the first routing information from the second PE device 206, and the gateway 210 sends the second packet information to the first PE device 202 after the gateway 210 is switched to receive the second routing information from the first PE device 202.
Wherein the gateway 210 is instructed not to treat the first PE device 202 as the next hop when the gateway 210 does not receive the first routing information from the first PE device 202 within a first threshold time, and the gateway 210 is instructed not to treat the second PE device 206 as the next hop when the gateway 210 does not receive the second routing information from the second PE device 206 within a second threshold time.
The first threshold time and the second threshold time may be the same or different.
Through step S408, dynamic disaster recovery may be implemented when the link between first PE device 202 and first CE device 204 or the link between second PE device 206 and second CE device 208 is jittered.
