Description

Technical Field

[0001] This application relates to the technical field of IT and software development, and particularly relates to a method for actively detecting a BM by a BMGW-VIP cluster. Background Art

[0002] Cloud servers in cloud computing services can be divided into virtual cloud hosts of the virtual type and physical cloud hosts, which are basic services in cloud services. Among them, physical cloud hosts can be roughly divided into ordinary physical machines, also known as ordinary bare metal servers, abbreviated as BM, that is, physical machines with intelligent network cards. A bare metal server is a hardware device with the characteristics of a traditional physical server and also has the virtualization service function of cloud computing technology. It is the product of the combination of the advantages of hardware and software, and its essence is a server that combines cloud computing service functions and provides physical device performance. The bare metal server can enter the cloud through the bare metal gateway BMGW, and through the BMGW, it can seamlessly dock and be compatible with other cloud services provided by cloud providers, such as various cloud products like VPC private networks, cloud database services, EIP, shared bandwidth, speed limit, cloud firewalls, etc. in network services.

[0003] The bare metal gateway BMGW provides various cloud services for the bare metal server to enter the cloud. To ensure the performance and reliability of the bare metal server entering the cloud, the bare metal gateway usually consists of multiple devices to form a BMGW cluster to provide services for the BMGW. China Telecom Cloud mainly provides access services for BMs in the resource pool through the BMGW-VIP cluster and the BM access switch. As Figure 2 shown, it is a schematic diagram of a BM accessing the BMGW-VIP cluster. Among them, the management and control system is a system in the cloud for automatically managing and controlling bare metal, bare metal gateways, and access switches; the LEAF switch is a basic network-related switching and routing device; other clusters are other business clusters in the cloud.

[0004] As Figure 3 shown, the BM gateway is located on the BMGW cluster. Each member of the cluster is independent and can back up each other. Based on the VIP-based VXLAN tunnel between the BMGW-VIP cluster and the access switch for connection, the gateway of the subnet where the BM server is located is on the BMGW. When the packet of the BM server requesting the BM subnet gateway arrives at the BM cluster, it is directly replied by the BM where it is located.

[0005] CT Cloud mainly provides access services for BMs in the resource pool through the BMGW-VIP cluster and the BM access switch. The BMGW services of the cluster members hide overlay-related services such as VPC. Therefore, the BMs of the cluster members cannot use the general program ping to actively detect the overlay BM hosts. In addition, since the BMGW is deployed in the VIP mode, the data replied by the BM to the cluster is equally shared to the corresponding cluster members according to the encapsulation information of the outer VXLAN. Therefore, the request message and the reply message of the request message cannot be replied to the same BMGW. Summary of the Invention

[0006] This application aims to solve at least one of the technical problems in the related art to some extent. For this reason, an object of this application is to propose a method, a system, an electronic device, and a readable storage medium for actively detecting BMs in a BMGW-VIP cluster.

[0032] If the real IP of the BM carried in the ping packet is for the local machine, use the real IP of the BM to replace the destination IP of the inner-layer ping packet and send it to the kernel. If it is not for the local machine, use the real IP of the BM to replace the destination IP of the VXLAN and send it to the LEAF node.

[0033] The step that the BMGW cluster members receive the replied ping packet and forward the ping packet to the cluster member requested by the source according to the data of the ping packet includes:

[0053] Use the data of the ICMP request to carry the source IP of the packet, so that the cluster members can confirm the source request node by detecting the ping data, and then modify the VXLAN packet header again to forward the packet to the source request node, solving the problem of the same source and the same destination.

[0068] Embodiment 1

[0069] Figure 1 FIG. is a schematic diagram of a method for actively detecting a BM in a BMGW-VIP cluster provided by an embodiment of this application. As Figure 1 shown, a method for actively detecting a BM in a BMGW-VIP cluster includes:

[0070] Use the ping program in the BMGW-VIP cluster members to detect the IP of the BM, specify the VNI where the BM is located using the -p parameter, and the ping program sends a request to detect the BM to the BMGW service using ICMP;

[0071] Among them, the BMGW-VIP cluster is a BMGW cluster implemented based on VIP. The BMGW cluster is a VXLAN VTEP node of the BM cloud network. Each member of the BMGW cluster runs a routing protocol to establish a neighbor relationship with the LEAF switch interconnected with the cluster and publishes the cluster VIP address. The VIP routes published by the cluster form VIP equivalent routes on the LEAF switch. In this way, the service traffic encapsulated by VIP+VXLAN tunnels is automatically load-balanced to the cluster members by looking up the equivalent routes on the LEAF switch outside the cluster. After the cluster members process the service, they obtain the VIP of the next cluster and use the VIP to encapsulate the VXLAN packet again to send the service traffic to the subsequent clusters to complete the forwarding of tenant services. The BM access switch is a switch connecting bare metal servers and is a VTEP node of the VLXAN tunnel for bare metal to enter the cloud. The destination address of the VXLAN tunnel is the VIP address of the BMGW cluster.

[0072] In the BMGW-VIP cluster members, use the ping program to detect the IP of the BM, and use the -p parameter to specify the VNI where the BM is located. The ping program uses ICMP to send a request to detect the BM to the BMGW service, including:

[0073] Fill the parameter -p with the content of the general ping program to specify the VNI where the BM is located. Here, VNI is the tunnel identifier of VXLAN. After executing the -p parameter, the general ping program can automatically fill the content of BM-VXLAN-VNI into the ping packet. The specific form is as follows:

[0074] ping BM-IP -p BM-VXLAN-VNI -c xx -i yy.

[0075] The BMGW service receives the ICMP request to detect the BM, detects the ping packet, and extracts the VNI as the VNI parameter for encapsulating the BM VXLAN tunnel packet;

[0076] The steps for the BMGW service to receive the ICMP request to detect the BM, detect the ping packet, and extract the VNI as the VNI parameter for encapsulating the BM VXLAN tunnel packet include:

[0077] The BMGW service receives the ICMP request to detect the BM;

[0078] Detect the ping packet;

[0079] If there is BM-VXLAN-VNI in the ping packet, extract the BM-VXLAN-VNI field;

[0080] Use the BM-VXLAN-VNI field to find the subnet of the BM, obtain the subnet gateway IP and the VXLAN information required to access the BM;

[0081] As the VNI parameter for BM VXLAN tunnel packet encapsulation.

[0082] Among them, ICMP is the protocol used by Ping. Ping uses the requests and replies in the ICMP protocol to perform functions. When sending a Ping request, the Ping tool creates an ICMP request message and sends it to the target host, and then waits for the ICMP reply response from the target host.

[0083] The BMGW service modifies the source IP of the ping packet according to the information queried by the VNI, fills the source IP into the ping packet, encapsulates the VXLAN packet using the VNI where the BM is located, and sends it to the LEAF node;

[0084] The step that the BMGW service modifies the source IP of the ping packet according to the information queried by the VNI, fills the source IP into the ping packet, and encapsulates the VXLAN packet using the VNI where the BM is located and sends it to the LEAF node includes:

[0085] The BMGW service queries the information according to the VNI;

[0086] Use the subnet gateway IP to replace the source IP of the ping packet;

[0087] Fill the source IP of the ping packet into the ping packet;

[0088] Encapsulate the original ping packet using the VXLAN encapsulation information;

[0089] Send the encapsulated original ping packet to the LEAF node.

[0090] The step of sending the encapsulated original ping packet to the LEAF node includes:

[0091] The BM receives the request of the ping packet and generates a reply packet;

[0092] The reply packet is encapsulated with VXLAN by the BM access switch;

[0093] Forwarded to the BMGW cluster members, and the cluster members detect that the ping reply packet is a reply packet requesting the subnet gateway IP;

[0094] If the BM's real IP carried in the ping packet is for the local machine, then use the BM's real IP to replace the destination IP of the inner-layer ping packet and send it to the kernel. If it is not for the local machine, then use the BM's real IP to replace the destination IP of VXLAN and send it to the LEAF node.

[0095] The BMGW cluster member receives the replied ping packet and forwards the ping packet to the cluster member that made the source request according to the data in the ping packet;

[0096] The step that the BMGW cluster member receives the replied ping packet and forwards the ping packet to the cluster member that made the source request according to the data in the ping packet includes:

[0097] The BMGW cluster member receives the replied ping packet;

[0098] The BMGW cluster member needs to parse the received replied ping packet;

[0099] Forward the ping packet to the cluster member that made the source request according to the data in the ping packet.

[0100] After receiving the ping packet, the cluster member that made the source request restores the ping packet according to the data in the ping packet and sends it to the kernel.

[0101] The step that the BMGW-VIP cluster member that made the source request receives the ping packet, restores the ping packet according to the ping packet, and sends it to the kernel includes:

[0102] The BMGW-VIP cluster member that made the source request receives the ping packet;

[0103] Detect the received ping packet;

[0104] Restore the ping packet according to the ping packet;

[0105] Send it to the kernel.

[0107] Figure 6 It is a schematic diagram of a system for the BMGW-VIP cluster to actively detect the BM provided by an embodiment of the present application. As Figure 6 shown, a system for the BMGW-VIP cluster to actively detect the BM, the system includes:

[0108] A sending request module, which is used to use the ping program in the BMGW-VIP cluster member to detect the IP of the BM, specify the VNI where the BM is located using the -p parameter, and the ping program uses ICMP to send a request to detect the BM to the BMGW service;

[0109] Detection module: The BMGW service receives an ICMP probe BM request, detects the ping packet, and extracts the VNI as the VNI parameter for encapsulating the BMVXLAN tunnel packet.

[0110] Modification module: Used for the BMGW service to modify the source IP of the ping packet according to the information queried by the VNI, fill the source IP into the ping packet, encapsulate the VXLAN packet with the VNI where the BM is located, and send it to the LEAF node.

[0111] Forwarding module: Used for the BMGW cluster members to receive the replied ping packet and forward the ping packet to the cluster member requested by the source according to the data in the ping packet.

[0112] Send to kernel module: Used for the cluster member requested by the source to restore the ping packet according to the data in the ping packet after receiving it and send it to the kernel.

[0113] Embodiment 3

[0114] Figure 4 It is a schematic diagram of the packet forwarding process related to the BMGW service provided by an embodiment of the present application. As Figure 4 shown, the packet forwarding process related to the BMGW service includes:

[0115] After the BMGW of BMGW member 1 receives the ping packet through the VETH-BMGW interface, it detects the content of the ping packet. If the BM-VXLAN-VNI exists in the ping packet, it extracts this field, uses the BM-VXLAN-VNIi field to find the subnet of the BM, obtains the subnet gateway IP and the VXLAN information required to access the BM, replaces the source IP of the ping packet with the subnet gateway IP, fills the source IP of the packet into the ping packet, encapsulates the original ping packet with the VXLAN encapsulation information. After the BM receives the ping request from the BM, it generates a reply packet. After the reply packet is encapsulated with VXLAN by the BM access switch, it is forwarded to a certain member of the BMGW cluster. The cluster member detects the ping reply and finds that it is a reply packet requesting the subnet gateway IP. If the BM real IP carried in the ping packet is for this machine, it replaces the destination IP of the inner-layer ping packet with the BM real IP and sends it to the kernel; if it is not for this machine, it replaces the destination IP of the VXLAN with the BM real IP and sends it to the LEAF node. The LEAF node forwards the packet to the real member node. After the cluster member node receives the packet and detects that the content of the ping reply belongs to this machine, it replaces the destination IP of the inner-layer ping packet with the BM real IP and sends it to the kernel.

[0116] As Figure 5As shown in the figure, the detailed steps of message forwarding related to BMGW service are as follows:

[0117] Receive a ping request message, that is, request message 1. The source IP of the message is the real IP of BMGW, the destination IP is the IP of the target BM, and the content is the content filled with -p;

[0118] The BMGW service extracts the VNI information, searches for the subnet according to the content of the VNI information, and obtains the subnet gateway IP and VXLAN encapsulation information;

[0119] The BMGW service replaces the source IP of request message 1 with the subnet gateway IP and fills the real IP of BM into the data to generate request message 2;

[0120] The BMGW service encapsulates request message 2 with VXLAN information to generate request message 3;

[0121] The BMGW service receives the reply message from the BM and replies with the reply message;

[0122] Judging according to the real IP of BM in the reply message, if the ping message is not the reply message requested by the local machine, then use the real IP of BM to replace the destination IP of the outer layer of VXLAN and reply with message 2;

[0123] Decapsulate reply message 2, modify the destination IP to the real IP of BM according to the filled content of the reply message, generate reply message 3, and then send it to the Linux kernel.
