Description

Cluster information transmission method and device

Technical Field

The present application relates to the field of network security technologies, and in particular, to a method and an apparatus for transmitting cluster information.

Background

With the continuous development of technology, the use of clusters (or called computer clusters, server clusters or node clusters) is gradually increased, for example, a kafka cluster is a cluster built based on a distributed stream processing system, and comprises a plurality of different nodes (or called servers), each node can deploy different functions and services, for example, in the process of using the kafka cluster, a client can send a request to the cluster through own requirements, and the cluster feeds back corresponding information so as to realize data transmission between the client and the cluster. In the process of transmitting cluster information, for safety, a gatekeeper is generally arranged between the client and the cluster, and blocking between an external network and an internal network is realized through the gatekeeper, so that safety is improved.

At present, the existing transmission mode of the cluster information is mainly based on that the gatekeeper directly configures the cluster node corresponding to the function required by the client, that is, when the client sends a request and the node corresponding to the function or service required by the request is just the node pre-configured in the gatekeeper, then the cluster directly feeds back the cluster information to the client, and the gatekeeper also releases the feedback information, and in the process, the corresponding address information of the node contained in the cluster information is fed back to the client. However, in practical applications, once a hacker uses a client, the existing transmission manner of the cluster information will expose the relevant information, especially the address information, of the cluster node to the client, so that the address information of the cluster is revealed, thereby affecting the security of the cluster device.

Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.

The embodiment of the application provides a method for transmitting cluster information, which is used for a data transmission system, wherein the data transmission system comprises the following steps: the data transmission system comprises a client, a cluster and a gatekeeper positioned between the client and the cluster, wherein a preset mapping relation between gatekeeper address information of the gatekeeper and cluster address information of the cluster is pre-configured in the data transmission system. As shown in fig. 1, the method includes:

101. and obtaining cluster information corresponding to the clusters.

Wherein, the cluster address information is obtained from the cluster information.

In this embodiment, the cluster information may be understood as information sent by a cluster in the interaction process of the cluster device and the client, and based on a requirement of a communication protocol, the cluster information necessarily includes related attribute information of the cluster device, which includes cluster address information, where the cluster address information may be understood as information that may represent an address of a cluster, for example, various information such as an IP address, port information, and the like. The IP address (Internet Protocol Address) refers to an internet protocol address, which is translated into an internet protocol address, and is information used to determine a network location of a device in a network, and the port information may be understood as "a port" which may be considered as an outlet for communication between the device and the outside. Ports can be divided into virtual ports and physical ports, where virtual ports refer to ports within a computer or within a switch router, typically used by individual functions or services. Therefore, in this embodiment, in order to ensure the security of the cluster device, it is necessary to acquire cluster address information in the cluster information. Specifically, the process of obtaining the cluster address information includes, but is not limited to, obtaining the address information from Metadata in the cluster information, where Metadata (english: metadata), also called intermediate data and relay data, is a data for describing data, mainly describing data attributes. Metadata is primarily used to support functions such as indicating storage locations, history data, resource lookups, file records, and the like. Metadata is an electronic catalog, and in order to achieve the purpose of cataloging, the contents or characteristics of data must be described and collected, so as to achieve the purpose of assisting in data retrieval. Accordingly, cluster address information describing information such as an IP address and a port can be acquired from metadata of the cluster information.

102. And determining the gateway address information corresponding to the cluster address information based on a preset mapping relation.

The preset mapping relation comprises network gate address information corresponding to each cluster address information.

In the method described in this embodiment, since the cluster device is implemented based on the gatekeeper in the process of client interaction, where the gatekeeper may be understood as an information exchange device for blocking between the client and the cluster, or proxy device, which is mainly used to divide the network between the client and the cluster by two devices at two ends, that is, the client and the cluster, where the main manner of division may be as shown in fig. 1-a, the gatekeeper may be divided into inner and outer sides, and interact with the corresponding client and cluster respectively, and the inner and outer sides perform data transmission through exchange cards, that is, in this process, actually, the client establishes a connection with one end outside the gatekeeper in the diagram, then the cluster establishes a connection with one end inside the gatekeeper, and then the gatekeeper between the inner side and the gatekeeper outer side is connected through the exchange card built in the gatekeeper, so that in the communication transmission process actually does not establish a connection relationship between the client and the cluster, but forms a network with two sides different based on the gatekeeper. Therefore, in this embodiment, in order to ensure that the subsequent cluster information is prevented from leaking when sent to the client, the gatepost address information corresponding to the cluster address information may be determined in this step based on the preset mapping relationship. The preset mapping relationship may be understood as preset address information of each cluster and address information of a corresponding node or port of the gatekeeper when the gatekeeper forwards the cluster message.

103. In the cluster information, the gatekeeper address information is used for replacing the cluster address information.

After the gateway address information corresponding to the cluster address information is determined, the cluster address information in the cluster information can be replaced based on the gateway address information, so that the client can only acquire the gateway address information corresponding to the cluster address information instead of the original cluster address information when the cluster information is transmitted later.

104. And transmitting the replaced cluster information to the client.

After the cluster address information is replaced by the gateway address information, the obtained replaced cluster information does not actually contain the original cluster address information, so that even if a subsequent client side has malicious intent or even attack intent, the attack on the cluster cannot be directly realized based on the gateway address information, and the safety of cluster equipment is ensured.

The application provides a method for transmitting cluster information, which can firstly acquire cluster information corresponding to a cluster, wherein the cluster information comprises cluster address information; then, based on a preset mapping relation, determining the gatepost address information corresponding to the cluster address information; and then, in the cluster information, replacing the cluster address information by adopting the gateway address information, and finally transmitting the replaced cluster information to a client, thereby realizing the transmission function of the cluster information. Compared with the prior art, the method and the device have the advantages that the address information in the cluster information can be replaced with the corresponding gatekeeper address information according to the preset mapping relation in the process of transmitting the cluster information, so that the client can only acquire the gatekeeper address information instead of the address information of the original cluster equipment in the process of transmitting the cluster information to the client, the situation that the address of the cluster is revealed to the client in the process of interaction between the cluster and the client is avoided, and even if the client is attacked by an attacker such as a hacker, the address information of the cluster cannot be acquired, and the problem that the hacker attacks the cluster equipment based on the address information is avoided, so that the security of the cluster equipment is guaranteed.

For more detailed description below, another method for transmitting cluster information is provided in the embodiments of the present application, specifically as shown in fig. 2, where the method includes:

201. and obtaining cluster information corresponding to the clusters.

Wherein the cluster information comprises cluster address information.

In particular, since in practical applications, the cluster information may consist of a plurality of information packets, in this case, the cluster information includes at least one information packet;

based on this, the process of obtaining the cluster information corresponding to the cluster in this step may include:

based on the judgment result, the following two aspects can be classified:

on the one hand, if all the information contents of the cluster information are received, combining a plurality of information packets corresponding to the cluster information to obtain the cluster information.

On the other hand, if it is determined that all the information of the cluster information is not received, the information packet corresponding to the cluster information is cached, so that when it is determined that all the information contents of the cluster information are received, the cluster information is obtained by combining.

When it is determined that all the packets in the cluster information have been received, it is indicated that the cluster information has completed all transmission from the cluster device to the gatekeeper, and then the complete cluster information can be obtained based on the combination of the packets. Therefore, when the cluster information corresponding to the clusters is acquired, the received information packet can be checked, so that the integrity of the cluster information is ensured, and the problem of data loss caused by packet loss during transmission through a gateway is avoided.

When it is determined that all the packets are not received in the cluster information, it is indicated that the cluster side does not send all the packets, which may be caused by problems such as network, and in this case, the received packets need to be cached in the local area of the gatekeeper, so as to ensure that the packets are merged when the remaining packets are subsequently received, so that the packet loss in the process of forwarding the cluster information is avoided, and meanwhile, it is ensured that after the packets are cached, the remaining packets do not need to be waited for all the time, and other packets can be continuously received, thereby avoiding the problem of communication blocking.

Further, in the above-described process of determining whether the entire content of the cluster information is received, the determination may be actually made based on the data amount determined by the header information of the packet and the data amount of the received packet. Based on this, the determining in this step whether all information contents of the cluster information have been received based on the header information of the packet includes:

and determining the data quantity of the cluster information through the header information of the information packet, and determining whether the data quantity of the information packet is consistent with the data quantity of the cluster information, wherein when the data quantity of the information packet is consistent with the data quantity of the cluster information, determining that all information contents of the cluster information are received, or else, not receiving all information contents.

For example, when it is determined that the data amount of the cluster information is 40 kilobytes based on the header information of the packet, if the total data amount of the packet that has been received is also 40 kilobytes, which are the same, it is indicated that the entire information content of the current cluster information has been received.

Based on this, when it is determined that the entire information content of the cluster information is not received based on the data amount of the packet, it is indicated that the current cluster information may be divided into a plurality of packets to be sent, and if it is determined that the entire information content of the cluster information is received in this step, the plurality of packets corresponding to the cluster information are combined to obtain the cluster information, which may specifically be executed: if the data quantity of the cluster information is not consistent with the data quantity of the information packet, caching the information packet, merging the newly added information packet with the cached data packet to obtain the cluster information,

When the packet-based data size is not equal to the packet-based data size of the cluster information, it is indicated that the cluster information is transmitted in a plurality of packets, and then it is necessary to buffer already received packets and to combine the buffered packets with newly added packets when newly received packets are subsequently detected.

Further, in determining whether the entire information content of the cluster information is received based on the data amount, there may be a case in fact that, in case that the data amount of the current packet is the same as the data amount of the cluster information, it is indicated that the cluster information is actually transmitted in a packet manner, and after said determining whether the data amount of the packet is consistent with the data amount of the cluster information, the method further includes: and if the data quantity of the cluster information is consistent with the data quantity of the information packet, determining the information packet as the cluster information. Therefore, after the information packet is received, the information packet is directly used as cluster information for transmission without waiting for other subsequent information packets, and the transmission efficiency can be improved.

As can be seen from the foregoing description in this step, since the cluster information may be sent in a manner of a plurality of packets, the method in this embodiment needs to consider that the received packet is combined with a subsequently received packet in the process of transmitting the cluster information, and in this process, buffering the packet and combining a new packet with the buffered packet to obtain the cluster information includes:

firstly, sequentially storing a plurality of data contents in the information packet into each address unit of a preset address interval according to an arrangement sequence, and recording the data contents as a cached information packet;

then, after receiving the newly added information packet, determining the data volume of the newly added information packet;

and then, based on the data quantity of the newly added information packet and the data quantity of the cached information packet, the sum calculation is carried out between the newly added information packet and the cached information packet, and the data quantity of the newly added information packet and the cached information packet are compared, so that whether the cluster information is received or not can be determined, and the following two ways can be carried out in the process:

in one aspect, when it is determined that the sum of the data amount of the new packet and the data amount of the buffered packet is equal to the data amount of the cluster information, the data content of the new packet is stored starting at a next address unit of a last address unit stored in the buffered packet, and a plurality of data contents from a first address unit stored in the preset address section of the buffered packet to a last address unit stored in the preset address section of the new packet are determined as the cluster information.

On the other hand, when it is determined that the sum of the data amount of the newly added packet and the data amount of the buffered packet is larger than the data amount of the cluster information, the data content of the newly added packet is stored starting at the next address unit of the last address unit stored in the buffered packet, and a plurality of data contents from the first address unit of the buffered packet stored in the preset address section to a target address unit determined from the first address unit of the newly added packet stored in the preset address section and an address offset determined by a storage specification of a remaining data amount and an address unit determined by a difference calculation between the data amount of the cluster information and the buffered packet are determined as the cluster information.

In the above two aspects, in the case of the previous aspect, it may be understood that the data amount of the current newly added packet plus the data amount of the cached packet is just equal to the data amount of the cluster information, which indicates that the newly added packet and the cached packet just form the complete cluster information. In the process of caching, the middle character information of the information packet is actually stored in the address unit with the same byte in the form of bytes, and after the new information packet is received, the character content of the new information packet is continuously stored in the next address unit after the last address unit stored in the cached information packet, so that the character content of the cached information packet and the character content of the new information packet in the storage area are sequentially stored in the byte unit, and based on the property of the communication protocol of the cluster equipment, a plurality of information packets related to the cluster information are sequentially transmitted in the process of cluster information transmission, so that the data stored in the first address unit of the cached information packet to the last address unit stored in the new information packet is just complete cluster information, and the data content of the address interval can be directly determined as the cluster information. Therefore, in the process of caching data, orderly storage of data content is realized by means of continuous address units, realization of a merging function is ensured, a process of independently merging data is simplified, and the transmission efficiency of cluster information is improved.

Similarly, in the above two aspects, when it is determined that the total data size of the new packet and the buffered packet is larger than the data size of the cluster information, it may be actually understood that the "next part" of the previous cluster information and the "previous part" of the next cluster information are stored in the new packet, and then it is necessary to continue storing the new packet after continuing to store the address unit stored in the buffered packet according to the method described above, and then it is necessary to determine that the information "cut" is performed from that address to obtain the complete previous cluster information, and the position of the "cut" is actually the target address unit described in this embodiment. In this embodiment, the target address unit is actually determined by the data amount. Specifically, the execution process may be that the position where the last data content of the cached packet is stored is first determined, and may be recorded as an address 1, then the number of the cached packets is subtracted from the data amount of the cluster information to obtain a remaining data amount, where the remaining data amount is the remaining part of the cluster information in the newly added packet, and then the offset is determined based on the remaining data amount and the storage rule of the address unit, where when the remaining data amount is the same as the unit of the storage rule of the address unit, the remaining data amount is equal to the offset, for example, both are kilobytes, or both are bytes, and then both are equal to each other. The determined offset is actually the address unit of the offset found starting at address 1, resulting in the target address unit. If the false offset is 10, address 11 is searched from address 1, and the data content stored from address 1 to address 11 is the cluster information.

Further, because based on the characteristics of the communication transmission protocol, not all packets contain the content of the cluster information in the process of transmitting the cluster information in a plurality of packets, and the existence of the packets such as the connection state may be confirmed, then the next received packet needs to be checked in the process of buffering in the foregoing steps, so as to avoid buffering the data content of the non-cluster information. Based on this, before determining the data amount of the newly added packet, the method further includes:

In this embodiment, the target field of the specific header information may be an api_key field in the header file of the packet pdu, for example, in some cases, when a specific parameter of the api_key of the target field appears in a plurality of packets corresponding to a certain cluster information is 3, it is indicated that the packet includes the data content of the cluster information, and then the step of determining the data amount of the newly added packet in the foregoing steps may be continued. When the data content of the packet is determined based on the destination field, which does not involve the cluster information, then there is no need to perform other steps including determining the data amount of the newly added packet and subsequent steps, and to continue waiting for subsequent packets.

Further, before determining whether all information contents of the cluster information have been received, there may be some cases, for example, the information packet itself involves less information contents, and the condition of parsing the header information cannot be satisfied, for example, the data amount of the header information is too small. In this embodiment, before determining whether all information contents of the cluster information have been received based on the header information of the packet, the method further includes:

Therefore, whether the header information is complete or not is checked by utilizing the data quantity of the header information, and the problem of analysis failure caused by incomplete analysis of the header information can be effectively avoided, so that the follow-up steps can be smoothly carried out, and the whole cluster information transmission operation can be smoothly executed.

202. Setting a corresponding gateway IP address for the node IP address of each node in the cluster, and setting a corresponding gateway port for the node port of each node in the cluster.

Since in practical application, each cluster belongs to a device group formed by a plurality of nodes, each node corresponds to one physical device or virtual device, the virtual device can be a virtual machine in the form of a container arranged in the physical device, and one physical device can be provided with a plurality of virtual devices. In such a cluster, each of the different functions and services are deployed at different nodes, and when a client needs to use a certain function or call a certain service, a request is initiated to a corresponding node of the cluster, so that the feedback implementation is based on the corresponding node of the cluster.

Based on the above, in the process of guaranteeing the security of the cluster, the security of each node in the cluster is guaranteed. Thus, in this embodiment, the foregoing cluster information may be actually understood as information sent by a certain node in the cluster, and then the cluster address information is actually, that is, the address information of the node in the cluster, and, in addition, since the cluster address information may be actually divided into two parts of an IP address and a port, then the two parts are respectively included in the cluster address information and the gatepost address information.

Based on this, the first network address comprises a node IP address of the cluster; the first port comprises a node port of a cluster; the second network address comprises a gatekeeper IP address, and the second port comprises a gatekeeper port; the cluster comprises at least one node, and each node corresponds to one node IP address and one node port.

In this way, in this step, by setting a corresponding gatekeeper IP address for the node IP address of each node of the cluster, a corresponding gatekeeper port is set for the node port of each node of the cluster, so as to lay a foundation for determining a preset mapping relationship based on the corresponding relationship between the two.

203. A first relationship is determined based on the node IP address and the gatekeeper IP address, and a second relationship is determined based on the node port and the gatekeeper port.

If the corresponding gateway IP address is set for the node IP address in the foregoing step, the first relationship may be determined based on the relationship between the two, and similarly, if the corresponding gateway port is set for the node port in the foregoing step, the second relationship may be determined based on the relationship between the two. Therefore, a foundation can be laid for determining corresponding information about the node IP address and the node port in the cluster address information in the cluster information based on the first relation and the second relation.

204. And determining the gateway address information corresponding to the cluster address information based on a preset mapping relation.

Specifically, the cluster address information includes a first network address and a first port; the gateway address information comprises a second network address and a second port; the preset mapping relation comprises a first relation and a second relation, and the first relation is used for representing the corresponding relation of each first network address and each second network address; the second relationship is used for representing the corresponding relationship between each first port and each second port;

based on this, this step, when executed, may include:

In this step, since the cluster address information can be divided into two parts, namely, a network address and a port, the process of determining the gatepost address information corresponding to the cluster address information based on the preset mapping relationship is actually divided into two parts, namely, determining the network address and confirming the port. For the former, it may be determined based on a first relationship among preset mappings, and for the latter, it may be determined based on a second relationship among preset mappings. In this way, in determining the cluster address information, it is ensured that the second network address corresponding to the first network address of the cluster, that is, the network address provided by the gatekeeper, is determined based on the first relationship, and meanwhile, the second port corresponding to the first port of the cluster, that is, the port provided by the gatekeeper, is determined based on the second relationship, so that a function of determining specific contents in the cluster address information according to the corresponding relationship is realized.

Further, based on the foregoing step, it may be known that, in a case where the preset mapping relationship includes a first relationship and a second relationship, and the first network address is specifically a node IP address, and the second network address is specifically a gatekeeper IP address, the first port is a node port, and the second port is a gatekeeper port, in this step, the second network address corresponding to the first network address is determined based on the first relationship, and the second port corresponding to the first port is determined based on the second relationship, where the performing may specifically be:

The first relation is used for determining the gateway IP address corresponding to the node IP address, and the second relation is used for determining the gateway port corresponding to the node port, so that the effect of determining the node IP address and the node port from the gateway side is achieved, and a data foundation is laid for subsequent replacement. Meanwhile, the two angles based on the first relation and the second relation are respectively determined, so that the possibility of confusion of the IP address and the port is avoided, and the accuracy of a determination result is ensured.

205. In the cluster information, the gatekeeper address information is used for replacing the cluster address information.

Specifically, the step may include:

and when the byte length of the gatekeeper address information is consistent with the byte length of the cluster address information, replacing the cluster address information with the gatekeeper address information in the cluster information.

Since in practical applications the byte length of the metadata at the time of interaction between the cluster and the client is specified, in this case, if the byte length of the gatekeeper address information and the cluster address information at the time of replacement are different, the parsing of the subsequent client will be affected. Therefore, in the present embodiment, it is necessary to determine whether the byte lengths therebetween agree. Wherein if consistent, it can be directly replaced. Otherwise, if the two are inconsistent, the gatekeeper address information needs to be modified to ensure that the modified gatekeeper address information is the same as the original cluster address information in byte length. For example, when it is determined that the byte length of the gatekeeper address information is less than the cluster address information, a placeholder may be added to the gatekeeper address information, thereby ensuring that the modified gatekeeper address information is consistent with the byte length of the original cluster address information of the cluster information.

Further, in some cases, since the cluster address information is actually set in compliance with the communication specification set by the communication protocol, in practical application, the actually allowed byte length of the cluster address information may be within a length interval, and in this case, it is not necessary to strictly modify the gatepost address information to be consistent with the byte length of the cluster address information, but only to ensure compliance with the requirement of the communication specification.

Based on this, the replacing the cluster address information with the gatekeeper address information in the cluster information includes:

when the byte length of the gatekeeper address information is inconsistent with the byte length of the cluster address information, modifying the gatekeeper address information based on the communication specification of the cluster information to obtain corrected gatekeeper address information, and replacing the cluster address information in the cluster information based on the corrected gatekeeper address information, wherein the byte length of the corrected gatekeeper address information accords with the communication specification.

Thus, when it is determined that the byte length of the gatekeeper address information is inconsistent with the byte length of the cluster address information, the gatekeeper address information can be modified based on the communication specification of the cluster information to ensure that the byte length of the corrected gatekeeper address information conforms to the communication specification. Of course, no modification may be required if it is determined in this process that the byte length of the current gatekeeper address information itself already complies with the communication specification.

206. And transmitting the replaced cluster information to the client.

When the cluster address information of the cluster information is replaced, the obtained replaced cluster information can be forwarded to the client, and the client can only acquire the port and the IP address provided by the gateway instead of the node port or the node IP of the cluster based on any information such as the gateway address information, the corrected gateway address information and the like after acquiring the cluster information, so that the problem of address leakage of the nodes of the cluster can be ensured, and the safety of the cluster equipment is improved.
