Background

In internet services, server states are often detected, so that the server can execute corresponding services according to the server states, and security and reliability of the server executing the services are guaranteed.

In the prior art, in the process of detecting a server in a Private network (VPC), a detection server needs to be deployed inside the VPC, and needs to be deployed to each VPC (every time a VPC is generated, a complete set of detection server deployment needs to be performed), and the detection server needs to occupy resources, devices and the like of the VPC, and then performs server detection based on a VPC internal network. For example, the VPC intranet may send an Internet Control Message Protocol (ICMP) packet to the server through a ping command, and determine whether the server is in a normal operation state or whether a connection link with the server is in a normal connection state based on whether a response Message returned by the server is received.

In the research and practice process of the prior art, the inventor of the present invention finds that deploying the probe server inside the VPC network occupies the deployment and construction of the probe server by the VPC network resources, which is not only limited by the resource management capability in the VPC network (for example, some resources in the VPC cannot be flexibly scheduled), but also needs to change the composition of the resources in the VPC network, and is very inconvenient.

The detection server may be configured to detect a specified target server, the detection period and the detection mode are scheduled by the management server, and report a detection result to the management server, for example, a detection packet may be generated according to detection configuration information received from the management server, and the detection packet is sent to the proxy server, where the detection server may include one or more detection servers. The proxy server may be configured to convert an address and forward a probe packet or a probe result, and the proxy server may be connected to a target server outside the system, and the proxy server may include one or more proxy servers, for example, the proxy server may receive an address mapping relationship sent by the management server, and after receiving the probe packet sent by the probe server, convert an address of the target server to be probed in the base network into an address in the private network, and access the private network based on the converted address, and forward the probe packet to the target server in the private network; and after receiving the detection result returned by the target server, converting the address of the target server in the private network into the address in the basic network, and forwarding the detection result to the detection server based on the converted address.

The management server, the detection server and the proxy server are located in a basic network, the basic network is physical, such as an underlay network, a virtualized network, such as an overlay network, can be constructed on the basis of the basic network, and the virtualized network can be a public cloud virtualized network or a private cloud virtualized network (a more demanding virtualized network), and the like. The basic network can be a network of a basic forwarding architecture of the current data center network, and the basic network refers to a physical basic layer as long as any two routes on the data center network can be reached; the basic network can be completed by technical improvement, device quantity enlargement, bandwidth scale and the like of the physical network device, and the basic network comprises the traditional network technology.

The target server in fig. 1 is a detected server, and is located in a private network (i.e., VPC), where the private network may be a customizable network space (e.g., overlay network), and may deploy service resources such as a server, load balancing, a database, and a non-relational database (Not only sql, Nosql) block storage in the private network, and may freely divide a network segment or make a routing policy in the private network; the private network can be configured with a public network gateway to access the Internet (namely the Internet), and meanwhile, the public network or private line access is supported to be configured to build a hybrid cloud, the private networks are logically isolated from one another, and the like.

It should be noted that the scenario diagram of the server detection system shown in fig. 1 is only an example, and the server detection system and the scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention.

The following are detailed below.

In this embodiment, a description will be made from the perspective of a server probe system, which may be specifically integrated in a network device such as a server or a gateway.

A server probe method, comprising: acquiring a detection packet in a basic network, wherein the detection packet is used for detecting a target server; acquiring an address mapped by a target server in a basic network to obtain a first address; converting the first address to a second address of the destination server in the private network; sending a probe packet to a target server located in the private network based on the second address; and receiving a detection result returned by the target server based on the detection packet.

Referring to fig. 2, fig. 2 is a flowchart illustrating a server detection method according to an embodiment of the present invention. The server detection method may include:

in step S101, a probe packet is acquired in the infrastructure network, and the probe packet is used to probe the target server.

The server detection system may be deployed in a base network, and a target server to be detected is located in a private network, so that the server detection system may obtain a detection packet in the base network, where the detection packet may include an address (for example, the address may be an Internet Protocol (IP) Protocol for interconnection between networks) mapped in the base network by the target server to be detected, a detection period, a detection Protocol, and the like. The probe Protocol may include a Control Message Protocol (ICMP) or a Teletype Network (Telnet).

The server detection system may acquire the detection packet at a preset time interval or acquire the detection packet when the configuration update exists, and the specific acquisition time may be flexibly set according to actual needs, which is not limited here.

In some embodiments, the step of acquiring the probe packet in the infrastructure network may include: (1) acquiring detection configuration information in a basic network; (2) generating a probe packet based on the probe configuration information.

Specifically, the server detection system in the base network may obtain the detection configuration information from the information base, or receive the detection configuration information sent by the configuration terminal, and of course, the detection configuration information may also be obtained in other manners. The configuration terminal may be a terminal configured to detect configuration information, and the terminal may be a mobile phone, a tablet computer, a notebook computer, a desktop computer, or the like. The probing configuration information may include an IP address, a probing period, a probing protocol, etc. mapped in the base network by the target server to be probed.

After the probe configuration information is obtained, a probe packet may be generated based on the probe configuration information, where the probe packet may include a five-tuple, such as a source address, a destination address, a source port number, a destination port number, and a transport layer protocol, in addition to a probe period and a probe protocol, and after the probe packet is obtained, a probe for the target server may be initiated.

When a plurality of target servers are provided, the detection configuration information corresponding to each target server can be respectively obtained, and the detection packets corresponding to each target server are respectively generated based on the detection configuration information corresponding to each target server.

In some embodiments, the step of obtaining the probe configuration information in the infrastructure network may include: receiving a configuration instruction in a basic network, and determining a target server to be detected, a detection period and a detection protocol according to the configuration instruction; and generating detection configuration information according to the target server, the detection period and the detection protocol.

The server detection system may obtain the detection configuration information by receiving a configuration instruction sent by a user through a configuration terminal in the infrastructure network, where the configuration instruction is used to set the detection configuration information. And then, determining information such as a target server to be detected, a detection period, a detection protocol and the like according to the configuration instruction, wherein the information is detection configuration information.

For example, the content examples contained in the probe configuration information may be: (1) IP address of target server a in the base network: UnderLayIP A; (2) detection period: 10 seconds; (3) the detection protocol comprises the following steps: an ICMP; IP address of target server B in the base network: UnderLayIP B, probe period: 20 seconds, probing protocol: telnet.

In some embodiments, the server probe system includes a plurality of probe servers, and the step of generating the probe packet based on the probe configuration information may include:

(a) acquiring state information of each detection server;

(b) determining the priority of each detection server according to the state information of each detection server;

(c) determining at least one detection server from a plurality of detection servers according to the priority of each detection server to obtain a target detection server;

(d) the control target probe server generates a probe packet based on the probe configuration information.

In particular, the server probe system may obtain the probe packets through the probe server, and when the server probe system includes one probe server, one or more probe packets may be obtained through the probe server. When the server probe system includes a plurality of probe servers, the priority of each probe server may be acquired, and one or more probe packets may be preferentially acquired by the probe server having the higher priority.

For example, status information of each probe server may be obtained, where the status information may include the capacity of the probe server, whether a probe is being launched or not launched, and then a priority of each probe server may be determined according to the status information of each probe server, for example, a weight value may be set for each type of information in the status information, where the higher the total weight value of the status information is, the higher the priority is, or the priority may be determined according to the capacity of each probe server, and the higher the priority is the larger the capacity is.

In this case, at least one probe server may be determined from the plurality of probe servers to obtain the target probe server according to the priority of each probe server, for example, the probe servers may be ranked from high to low according to the priority, one probe server with the highest priority may be determined from the plurality of probe servers to obtain one target probe server, or a plurality of probe servers with the highest priority may be determined from the plurality of probe servers to obtain a plurality of target probe servers. After determining the target server, one or more probe packets may be generated by the target probe server based on the probe configuration information.

In step S102, an address mapped by the target server in the base network is obtained, and a first address is obtained.

The server detection system may obtain an address mapped in the base network by the target server to be detected, to obtain the first address, for example, the first address may be extracted from the received detection configuration information, or an address setting instruction may be received, and the first address may be determined according to the address setting instruction. The first address may include an address corresponding to one, i.e., one, target server; or, the detection packet carries the first address, and the first address can be extracted from the detection packet; the first address may also include a plurality of addresses, that is, an address corresponding to each of the plurality of target servers, and a plurality of addresses are obtained.

In step S103, the first address is converted into a second address of the destination server in the private network.

Since the server detection system is deployed in the base network, the target server to be detected is located in the private network, and the first address obtained by the server detection system in the base network is an address mapped by the target server in the base network, the server detection system may convert the first address into an address of the target server in the private network to obtain the second address in order to perform data transmission with the target server.

In some embodiments, the step of converting the first address to a second address of the destination server in the private network may comprise:

(1) acquiring an address mapping relation between a basic network and a private network;

(2) and converting the first address into a second address of the target server in the private network according to the address mapping relation.

Specifically, the server detection system may obtain an address mapping relationship between the base network and the private network from a database storing the address mapping relationship, or the server detection system may receive the address mapping relationship between the base network and the private network sent by the terminal, or the server detection system may receive the establishment instruction, determine, based on the establishment instruction, an address of each target server corresponding to the base network and an address of each target server corresponding to the private network, and then establish the address mapping relationship between the base network and the private network according to the address of each target server corresponding to the base network and the address of each target server corresponding to the private network; and so on.

It should be noted that the obtaining manner of the address mapping relationship may be flexibly set according to actual needs, and specific contents are not limited herein.

The address mapping relationship may exist in a list form (e.g., an address mapping relationship table) or a text form (e.g., an address mapping relationship text), and after the address mapping relationship is obtained, the first address may be converted into a second address of the destination server in the private network according to the address mapping relationship, for example, the first address underway ip a may be searched from the address mapping relationship table, after the first address is obtained, a second address overlay ip B corresponding to the first address may be determined, and at this time, the first address may be replaced with the second address, and the like, so that the probe packet may be transmitted subsequently using the second address overlay ip B.

In some embodiments, the server probe system may include a plurality of proxy servers, and the step of converting the first address into the second address of the target server in the private network according to the address mapping relationship may include:

(a) acquiring state information of each proxy server;

(b) determining the priority of each proxy server according to the state information of each proxy server;

(c) determining at least one proxy server from a plurality of proxy servers according to the priority of each proxy server to obtain a target proxy server;

(d) and controlling the target proxy server to convert the first address into a second address of the target server in the private network according to the address mapping relation.

Specifically, the server probe system may perform address translation by using a proxy server, may perform address translation by using the proxy server when the server probe system includes one proxy server, and may acquire the priority of each proxy server and perform address translation by using a proxy server having a higher priority when the server probe system includes a plurality of proxy servers.

For example, status information of each proxy server may be obtained, where the status information may include the capacity of the proxy server, the agent being initiated, the agent not being initiated, and the like, and then the priority of each proxy server may be determined according to the status information of each proxy server, for example, a weight value may be set for each type of information in the status information, where the higher the total weight value of the status information is, the higher the priority is, or the priority may be determined according to the size of the capacity of each proxy server, and the higher the priority is the larger the capacity is.

In this case, at least one proxy server may be determined from the plurality of proxy servers to obtain a target proxy server according to the priority of each proxy server, for example, the proxy servers may be ranked from high to low in priority, one proxy server with the highest priority may be determined from the plurality of proxy servers to obtain one target proxy server, or a plurality of proxy servers with the highest priority may be determined from the plurality of proxy servers to obtain a plurality of target proxy servers. After the target server is determined, the first address can be converted into a second address of the target server in the private network through the target proxy server according to the address mapping relation, wherein the first address can comprise one or more addresses, and the second address can also comprise one or more addresses.

In step S104, a probe packet is transmitted to a destination server located in the private network based on the second address.

After the second address is obtained through conversion, the probe packet may be sent to a target server located in the private network based on the second address, for example, the second address may be added to the probe packet, and the second address may be used as a destination address indicating the target server to be probed, so that the probe packet may be sent to the target server based on the second address.

In some embodiments, when the second address includes a plurality of addresses, the step of sending the probe packet to the destination server located in the private network based on the second address may include:

and calling the multiple threads, and sending the detection packet to a target server in the private network in parallel through the multiple threads based on each second address.

Specifically, when the second address includes a plurality of addresses, it indicates that a plurality of target servers need to be probed, in this case, the probe packet may include a plurality of packets, and the server probe system may invoke a plurality of threads and respectively send each probe packet to a target server that needs to be probed in parallel based on each second address through the plurality of threads, or send each probe packet to a target server that needs to be probed in series based on each second address through the plurality of threads.

In step S105, a probe result returned by the target server based on the probe packet is received.

The target server may parse the probe packet after receiving the probe packet, and return a probe result to the server probe system based on the parsed probe packet, for example, may extract the second address from the probe packet, and then return the probe result based on the second address. After the detection result is obtained, the server detection system may perform detection again according to the detection period set in the detection configuration information. The detection of the servers in the VPC network is realized by each server in the basic network based on the VPC network environment; the detection of various network states of the server in the VPC network can be realized without changing the configuration of the VPC network, the network architecture and the like and expanding resources and adjusting the architecture.

In some embodiments, the server probe system may include a management server, and the step of receiving the probe result returned by the target server based on the probe packet may include:

(1) receiving a detection result returned by the target server based on the detection packet;

(2) extracting a second address from the detection result;

(3) converting the second address into the first address according to the address mapping relation;

(4) and sending the detection result to the management server based on the first address.

Specifically, the server probe system may include a management server, and manages the probe result through the management server, where the probe result may include a second address corresponding to the target server in the private network, and after receiving the probe result returned by the target server based on the probe packet, the server probe system may extract the second address from the probe result, and in order to enable data transmission with the base-capable management server, the server probe system may convert the second address into an address of the target server in the base network according to an address mapping relationship, to obtain a first address, and at this time, the probe result may be sent to the management server based on the first address.

In some embodiments, the step of receiving the probe result returned by the target server based on the probe packet may include:

when the target server generates a detection response packet within the preset time of receiving the detection packet, receiving a first detection result which is returned by the target server and is normal for the target server, wherein the first detection result is generated based on the detection response packet; and when the target server does not generate the detection response packet within the preset time of receiving the detection packet, receiving a second detection result of the target server abnormity returned by the target server.

The detection result may include that the target server is normal or the target server is abnormal, and the target server may be normal, that the target server is in a normal operation state, that a connection link between the target server and the target server is in a normal connection state, or that the target server is available; the target server exception may be that the target server is in a non-operational state, or that a connection link with the target server is in a disconnected state, or that the target server denies access, or that the target service is unavailable, etc.

Specifically, after receiving the probe packet, the target server may generate the probe response packet within a preset time, where the preset time may be flexibly set according to actual needs, and a specific value is not limited here. When the target server generates the probe response packet within the preset time of receiving the probe packet, it indicates that the target server is normal, at this time, the server probe system may receive a first probe result that the target server returns that the target server is normal, where the first probe result may be generated by the target server based on the probe response packet. When the target server does not generate the probe response packet within the preset time of receiving the probe packet, it indicates that the target server is abnormal, at this time, the server probe system may receive a second probe result of the target server being abnormal, where the second probe result may be that the probe response packet is not generated at the target server.

As can be seen from the above, in the embodiment of the present invention, the detection packet for indicating the target server to be detected can be obtained in the basic network, and the address mapped by the target server in the basic network is obtained, so as to obtain the first address; and then, converting the first address into a second address of the target server in the private network, sending a detection packet to the target server in the private network based on the second address, and receiving a detection result returned by the target server based on the detection packet. According to the scheme, the server detection system can be deployed in a basic network outside the private network, so that the server detection system can flexibly allocate resources of various servers (such as a detection server or a proxy server) to detect the target server, and the convenience and flexibility of detecting the server are improved.

The method described in the above embodiments is further illustrated in detail by way of example.

In this embodiment, a server detection system is deployed in a basic network, and a server to be detected is located in a private network (i.e., VPC), and the server detection system includes a management server, a detection server, and a proxy server, where the management server, the detection server, and the proxy server may be connected to each other through a wired network or a wireless network.

For example, as shown in fig. 3, the server detection system may include a management server, a plurality of detection servers (for example, the number of detection servers a to B may be flexibly set according to actual needs), and a plurality of proxy servers (for example, the number of proxy servers a to B may be flexibly set according to actual needs), where a plurality of servers (for example, the values of servers 1 to n, n may be flexibly set according to actual needs) may be detected by one proxy server, the servers to be detected may be in the same private network (for example, the server 1 and the server 2 are in the same VPC-a), or may be in different private networks (for example, the server 5 and the server 6 are in different VPCs).

For another example, as shown in fig. 4, the server probe system may include a management server, a probe server and a proxy server, and a plurality of servers (i.e. target servers) may be probed by the proxy server, where the plurality of servers to be probed may be in the same private network or different private networks. For convenience of explanation, the server probing process will be described in detail below by taking the architecture of fig. 4 as an example.

It should be noted that, a server probe system may include not only a management server, a probe server, a proxy server, etc., but this embodiment is only an example given for convenience of description, and should not be construed as a limitation on the types and numbers of servers in the server probe system, and the server probe process is similar regardless of how many and how many types of servers exist, and can be understood according to this example.

Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a server detection method according to an embodiment of the present invention. The method flow can comprise the following steps:

201. the management server sends the address mapping relationship to the proxy server.

The management server may obtain the address mapping relationship between the base network and the private network from a database storing the address mapping relationship, or the management server may receive the address mapping relationship between the base network and the private network sent by the terminal, and the like. The address mapping relationship may exist in a list form (e.g., an address mapping relationship table) or a text form (e.g., an address mapping relationship text), and the specific content is not limited herein.

After the address mapping relationship is obtained, the management server may send the address mapping relationship to the proxy server at preset intervals based on the identifier, address, or the like of the proxy server, or send the address mapping relationship to the proxy server when the address mapping relationship is updated, and the like, and the management server may be flexibly set according to actual needs, and specific contents are not limited here.

202. The proxy server stores the address mapping relationship.

After receiving the address mapping relationship sent by the management server, the proxy server may store the address mapping relationship.

203. The management server sends the probe configuration information to the probe server.

The probing configuration information may include an IP address, a probing period, a probing protocol, etc. mapped in the base network by the target server to be probed.

When the number of the target servers is multiple, the management server may respectively obtain the detection configuration information corresponding to each target server.

It should be noted that, when there are multiple probe servers, the management server may obtain the priority of each probe server, and send probe configuration information to the probe server with the higher priority.

and the proxy server 303 is configured to receive a second detection result of the target server being abnormal, where the second detection result is returned by the target server when the target server does not generate the probe response packet within the preset time of receiving the probe packet.

Specifically, after receiving the probe packet, the target server may generate the probe response packet within a preset time, where the preset time may be flexibly set according to actual needs, and a specific value is not limited here. When the target server generates the probe response packet within the preset time of receiving the probe packet, it indicates that the target server is normal, at this time, the proxy server 303 may receive a first probe result that the target server returns that the target server is normal, where the first probe result may be generated by the target server based on the probe response packet.
