【Detailed ways】

In order to better understand the technical solutions of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. As used in the embodiments of the present invention and the appended claims, the singular forms "a", "said" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

It should be understood that the term "and/or" used herein is just a description of the same field of associated objects, indicating that there may be three relationships, for example, A and/or B may indicate: A exists alone, and A exists and B, there are three cases of B alone. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present invention to describe preset ranges, etc., these preset ranges should not be limited to these terms. These terms are only used to distinguish preset ranges from one another. For example, without departing from the scope of the embodiments of the present invention, the first preset range may also be called the second preset range, and similarly, the second preset range may also be called the first preset range.

Depending on the context, the word "if" as used herein may be interpreted as "at" or "when" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrases "if determined" or "if detected (the stated condition or event)" could be interpreted as "when determined" or "in response to the determination" or "when detected (the stated condition or event) )" or "in response to detection of (a stated condition or event)".

In the prior art, the enterprise's business support management system performs data communication under network isolation, and the following common methods are adopted when performing data monitoring on each device:

(1) Mobile hard disk copy, used for the initial acquisition of data with little fluctuation. Using the method of mobile hard disk copying is prone to data errors, data tampering, etc., and it is easy to be infected with viruses. There is no approval function, and it is impossible to ensure whether the data is compliant; in addition, there is no log record, which cannot be traced, and it is difficult to centralize data. Control.

(2) Dual network card host, that is, a computer is installed with two network cards to connect to two different networks. In the way of using dual-network card hosts, its security is difficult to guarantee, and the cost of hardware implementation is relatively high.

(3) Cross-network FTP (File Transfer Protocol, file transfer protocol), mainly used for uploading and downloading files. Using the method of cross-network FTP, its security is low, and the transmission of large files is slow, and problems such as transmission errors and transmission interruptions are prone to occur.

(4) Gatekeeper Ferry is a kind of information security requirement for physical isolation through gatekeeper isolation. Using the gatekeeper ferry method, the transmission speed is relatively slow, and anti-virus inspection cannot be performed, there is no approval function, and centralized data management and control cannot be performed.

(5) Deploy routers and switches. Deploy switches in different network areas, and then realize data communication between each other through the configuration of routers. It is necessary to purchase additional hardware devices such as routers and switches, and at the same time need to allocate resources such as IP, which is time-consuming and laborious. It also increases hardware costs and O&M cost.

It can be seen that some of the existing methods adopted above have poor data communication effects, and problems such as data errors may occur. In addition, even if the data communication effect can be guaranteed to a certain extent, the resources that need to be consumed are relatively large .

An embodiment of the present invention provides a multi-level cascade communication system for cross-network collection, the system includes:

Intranet, wherein, the collection component is deployed in the intranet, and the collection gateway HUB is deployed according to the firewall type, and the collection component and the collection gateway HUB have internal connection ports.

Understandably, the intranet may include multiple subnets, such as subnet A, subnet B, and subnet C. In order to enable the enterprise's business support management system (such as BOMC (Business Operation Management Center)) to perform data communication under network isolation and realize data monitoring of each device, this embodiment can specifically be implemented in each sub-network in the intranet. A collection component is added, through which the data in the intranet subnet can be collected.

In one embodiment, a collection gateway HUB is also deployed on the computer equipment in the intranet (HUB is a multi-port transponder. When the HUB is the central device, even if a certain line in the network fails, it will not affect work on other lines). Wherein, the collection gateway HUB is not set arbitrarily, but is determined according to the deployment of the firewall type. Wherein, the firewall type includes DMZ (demilitarized zone, military management zone, also known as isolation zone), NAT (Network Address Translation, network address translation) and NALL (no firewall).

In the external network, the second-level HUB area is deployed in the external network, and internal and external connection ports are opened on the internal network and the external network. The internal and external connection ports are based on the collection gateway HUB and the second-level HUB area. The collection gateway HUB includes the dual-end mode of the server or client. The dual-end mode is used to establish a connection between the second-layer HUB area and the collection gateway HUB based on the type of firewall, so as to realize the transmission of data information from the internal network or external network.

In one embodiment, a layer-2 HUB area is deployed in the external network, and the layer-2 HUB area is deployed on the external network for connecting with the acquisition gateway HUB deployed in the internal network. Among them, whether it is the collection gateway HUB of the intranet or the HUB on the second-floor HUB area, both have a dual-end mode of the server or client. In this embodiment, in combination with the actual firewall type between the external network and the internal network, it is possible to flexibly set the collection gateway HUB or the HUB on the second-floor HUB area as the server or client. Thus, the collection gateway HUB and the HUB on the second-floor HUB area complete the connection in the form of server and client to realize data communication between the internal and external networks. Compared with the above-mentioned common processing methods, the data communication realized by the multi-level cascaded communication system for cross-network collection has a better effect of data communication, and it does not need to consume too much resources. Cascade communication system can be realized.

FIG. 1 shows a schematic diagram of a multi-level cascaded communication system collected across networks in this embodiment. As shown in Figure 1, the multi-level cascade communication system for cross-network collection includes subnet A, subnet B, and subnet C of the intranet, as well as collection components and collection gateway HUBs in each subnet. The collection gateway HUB is determined according to the firewall type deployment. Specifically, the collection gateway HUB includes DMZ HUB, NAT HUB and NALL HUB; The HUBs include DMZ HUB, NAT HUB and NALL HUB, and the external network also includes the collection service for data interaction with the second-level HUB area, as well as the database, kafka and WEB services for data interaction with the collection service.

When building the above multi-level cascade communication system for cross-network collection as shown in Figure 1, the following steps can be specifically included:

Step 1: Deploy the collection gateway HUB on the external interface host (machine C) of subnet A, deploy a collection component on other host devices in subnet A, and deploy subnet B and subnet C in a similar way to subnet A .

Step 2: Open the port, open port 14237 from the host where the collection component is located to the host where the collection gateway HUB of subnet A is located, the collection component is used as the client, and the collection gateway HUB of subnet A is used as the server. When the collection component starts, it will connect to the collection The listening port of the gateway HUB is 14237.

Step 3: Deploy a "layer 2 HUB area" on a certain host (machine D) in the network outside the subnet A/B/C. This layer 2 HUB area communicates with applications such as collection services and kafka outside the subnet, and is responsible for receiving Collect the command of the service and forward the collected data from the collection gateway HUB of the lower subnet.

Step 4: Open the port. The HUB on machine C in subnet A is used as the client, and the upper-level HUB on machine D outside subnet A is used as the server. You need to open port 14237 from machine C to machine D.

Step 5: After the acquisition components and the acquisition gateway HUB on each host are started, the acquisition component establishes a connection with the acquisition gateway HUB of the subnet, the subnet acquisition gateway HUB establishes a connection with the second-level HUB area, and the acquisition service between the secondary HUB area and the external network establish connection. The collected data is forwarded to the application program through the second-level HUB area, and the command issued by the collection service is also transmitted to a specific component through the second-level HUB area. Through the multi-level cascade technology, the multi-level cascade communication system for cross-network collection is established. .

Furthermore, in addition to the multi-level cascading function, the collection gateway HUB also has cluster support and routing capabilities.

Further, the connection relationship between the acquisition gateway HUB in the intranet and the HUB in the second-floor HUB area includes active connection and passive connection.

Understandably, when the collection gateway HUB is used as a client to connect to the HUB in the second-layer HUB area, the connection relationship is an active connection; when the collection gateway HUB is used as a server to connect to the HUB in the second-layer HUB area, the The connection relationship is a passive connection.

The connection relationship between the active connection and the passive connection is determined according to the firewall type of the internal network and the external network. Users can use the firewall type to deploy the collection gateway HUB and the second-layer HUB area that can realize the connection.

Further, when the firewall type is DMZ, the acquisition gateway adopts DMZ HUB, and uses DMZ HUB as the client to initiate a connection.

When the firewall type is NAT, the collection gateway uses a NAT HUB, and uses the HUB connected to the NAT HUB as the client to initiate a connection.

When the firewall type is NALL, the collection gateway uses NALL HUB, and uses the NALL HUB of the intranet as the client to initiate a connection.

Understandably, the relationship between the firewall type and the adopted connection policy can be shown in FIG. 2 .

When the firewall type is DMZ, the connection is established by the HUB in the DMZ; when the firewall type is NAT, the connection is established by the HUB connected to NAT; for the convenience of connection management, when the firewall type is NALL, the connection is established by the NALL HUB , do not use bidirectional connections.

Further, due to firewall restrictions, there are three situations:

1) The machine in subnet A can only actively initiate connections, but cannot accept connections; then DMZ HUB can be deployed on the subnet machines, and DMZ HUB can actively initiate connections. Make the internal network and external network connection.

The component relationship diagram of the communication system of 1) is shown in FIG. 3 .

2) The machine in subnet A can only accept connections passively, but cannot actively initiate connections; then a NAT HUB can be deployed on the machines in this subnet, and the upper-layer HUB connected to NAT can establish a connection;

The component relationship diagram of the communication system of 2) is shown in FIG. 4 .

3) The subnet machine does not have a firewall, and both parties can initiate a connection; then a NALL HUB can be deployed on the subnet machine, and the NALL HUB establishes a connection instead of a two-way connection;

The component relationship diagram of the communication system of 3) is shown in FIG. 5 .

Furthermore, the collection gateway HUB and the HUB in the second-floor HUB area use the ANF (ANF full name is AFNetworking, which is a lightweight network request open source framework) network framework as the basis to build the framework, including the transmission interface layer, management layer and service layer , where the transport interface layer is used for message queue, load balancing, server and client implementation.

Specifically, the gateway HUB and the HUBs in the second-floor HUB area are collected, and the HUB design diagram of the framework based on the ANF network framework is shown in Figure 6.

As can be seen from Figure 6, the HUB is logically divided into three layers: transmission interface, management, and service. Among them, the service layer is responsible for processing registration, routing update, parameter configuration, heartbeat and other messages, and also provides functions such as self-monitoring, version information reporting, configuration management, and log recording; the management layer is responsible for routing information, connection information management and query; The transport layer includes the implementation of message queues, load balancing, servers and clients, etc.

From the HUB design diagram shown in Figure 6, the dual-end mode of the HUB (which can be used as a client and a server) can be used to build a multi-level cascade system. Among them, the multi-level cascading system also provides the delivery interface and the receiving and processing of the bearer message, and at the same time provides information required for management such as connection management and routing management.

Further, the extranet also includes: collection service and application service, wherein the data in the application service includes the data transmitted from the collection service, and the collection service and application service are applied in the computer equipment of the extranet.

Specifically, application services include services such as databases invoked by applications, kafka, and web.
