Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a signaling interaction diagram of a universal serial bus USB device redirection method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:

s101, a target client sends a target client identification message of the target client to a server, wherein the target client is any client information in at least one client connected to the server;

s102, the server receives the identification information of the target client sent by the target client.

In this embodiment, the target client identification information includes the type, manufacturer information, network segment information, and the like of the target client.

In one embodiment, before receiving client identification information sent by a target client, a server receives the type and manufacturer information of the client sent by each client in at least one client; grouping the at least one client according to the type and the manufacturer information to obtain at least one client team, wherein the type and the manufacturer information of each client in the same client team are consistent; and determining a filtering rule corresponding to each client team, wherein the filtering rule comprises identification information of at least one USB device which can be redirected.

For example, the server receives the type and manufacturer information of each client sent by 10 clients, and divides the 10 clients into 3 teams according to the type and manufacturer information, wherein 4 clients of the first team are all B-type devices of a manufacturer a, 3 clients of the second team are all D-type devices of a manufacturer C, and 3 clients of the third team are all F-type devices of a manufacturer E.

After grouping 10 clients, filter rules for 4 clients of the first team are determined. For example, the filter rule for the clients of the first team may be 100 USB devices of a vendor or similar to a vendor product. Similarly, the filtering rule of the clients of the second team may be 100 USB devices of the C vendor or similar products to the C vendor, and the filtering rule of the clients of the third team may be 100 USB devices of the E vendor or similar products to the E vendor. In this way, clients of each team can redirect USB devices with better device compatibility.

In another embodiment, the server receives the network segment information of each client from each client in the at least one client; grouping the at least one client according to the network segment information to obtain at least one client group, wherein the network segment information of each client in the same client group is consistent; and determining the filtering rule corresponding to each client team.

For example, the server receives network segment information of each client sent by 10 clients, and divides the 10 clients into 2 teams according to types and manufacturer information, wherein 6 clients of a first team are clients with network segment information of an a area, and 4 clients of a second team are clients with network segment information of a b area.

After grouping 10 clients, filter rules for 6 clients of the first team are determined. For example, the filtering rule for clients of the first team may be 100U disk devices. The filtering rule for clients of the second team may be 100 cameras. Therefore, classified management can be carried out on the clients with different network segment information.

S103, the server determines a target client formation where the target client is located according to the target client identification information.

For example, the server may determine the team in which the target client is located according to the type of the target client and the manufacturer information, or may determine the team in which the target client is located according to the network segment information of the target client.

For example, if the type and the manufacturer information of the target client are B-type devices of manufacturers a, the target client team where the target client is located is the first team, and the target filter rule corresponding to the target client is 100 USB devices of manufacturers a or similar to the products of manufacturers a.

If the network segment information of the target client is the b area, the target client team where the target client is located is the second team, and the target filtering rule corresponding to the target client is 100 cameras.

S104, the server sends a target filtering rule corresponding to a target client formation to the target client;

s105, the target client receives the target filtering rule sent by the server;

s106, when the target client side determines that the target USB equipment is inserted, acquiring identification information of the target USB equipment;

s107, if the identification information of the target USB equipment exists in the target filtering rule, the target client redirects the target USB equipment.

For example, if the target filtering rule received and sent by the target client is 100 USB devices of a manufacturer a or similar to a manufacturer a, the client acquires the identification information of the target USB device when determining that the target USB device is inserted, and determines that the target USB device is the USB device of the manufacturer a and exists in the target filtering rule according to the identification information of the target USB device, and redirects the target USB device.

Illustratively, the target filtering rule further includes a usage duration of each USB device that can be redirected, and after the client redirects the target USB device, the client obtains the target usage duration of the target USB device and starts timing; and after the target use duration, forbidding the target USB equipment.

For example, after the identification information of the target USB device of the target client is determined to be the USB device of manufacturer a and exists in the target filtering rule, the service life of the target USB device is obtained to be 2 hours, the target USB device is redirected and then timing is started, and after 2 hours, the target USB device is disabled. In this way, the use of the USB device can be managed by time.

In one embodiment, the method further comprises:

if the target client determines that the identification information of the target USB equipment does not exist in the target filtering rule, sending a target USB equipment redirection application message to a server, wherein the target USB equipment redirection application message comprises the identification information of the target USB equipment; the server receives a target USB equipment redirection application message sent by the target client; the server adds the identification information of the target USB equipment to the target filtering rule to obtain an updated target filtering rule; the server sends the updated target filtering rule to the target client; the target client receives the updated target filtering rule sent by the server; and the target client redirects the target USB equipment according to the updated target filtering rule.

In another embodiment, the method further comprises:

the target client receives user identification information input by a user; the target client sends the user identification information to a server; the server receives user identification information sent by the target client, wherein the user identification information is input by a user on the target client; if the server determines that the user is a legal user according to the user identification information, determining the user grade of the legal user; the server determines a target filtering rule of the target client according to the user level, wherein different user levels correspond to different filtering rules, and the number of the USB devices which can be redirected in the filtering rule with the high user level is larger than the number of the USB devices which can be redirected in the filtering rule with the low user level; and the target client receives the target filtering rule of the target client sent by the server according to the user identification information.

For example, the user name and the password are input by the user c on the target client, the user name and the password are sent to the server after the user name and the password input by the user c are received by the target client, and the server stores a legal user list in advance, wherein the legal user list comprises the user name, the password and the user grade of each legal user. And if the server determines that the user name and the password of the user c exist in the legal user list, determining that the user c is a legal user, and determining the grade of the legal user. For example, the user ranks are high, medium, and low.

If the user level of the user c is determined to be high, the server determines that the target filtering rule of the target client is 100 manufacturers A or USB equipment similar to products of the manufacturers A according to the high user level, if the user level of the user c is determined to be medium, the server determines that the target filtering rule of the target client is 70 manufacturers A or USB equipment similar to products of the manufacturers A according to the user level, and if the user level of the user c is determined to be low, the server determines that the target filtering rule of the target client is 30 manufacturers A or USB equipment similar to products of the manufacturers A according to the low user level.

According to the USB redirection method provided by the embodiment of the disclosure, a target client can send target client identification information of the target client to a server; the method comprises the steps that a server receives target client identification information sent by a target client, wherein the target client is any one of at least one client connected to the server; the server determines a target client formation where the target client is located according to the target client identification information; the server sends a target filtering rule corresponding to a target client team to the target client; the target client receives a target filtering rule sent by the server; the method comprises the steps that when a target USB device is determined to be inserted, a target client side obtains identification information of the target USB device; if the identification information of the target USB equipment exists in the target filtering rule, the target client redirects the target USB equipment, and different clients correspond to different filtering rules, so that the condition that the same filtering rule is adopted for all the clients and the requirements under all scenes are not met is avoided, and the use requirements under more scenes can be met.
