Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a flowchart of a loopback processing method in some embodiments of the present application. The loopback processing method is used in a modem terminal system, wherein the modem terminal system is connected with a plurality of modems, and the method comprises the following steps:
s101, when a loopback detection trigger signal is detected, broadcasting an initial detection message to the plurality of modems.
S102, monitoring whether a first detection message returned by any modem is received, wherein the first detection message comprises the initial detection message and identification information of the modem forwarding the initial detection message.
S103, if at least one first detection message returned by any modem is received, extracting the identification information carried in each first detection message.
S104, disabling the uplink channel of the corresponding modem according to the identification information.
In step S101, the loopback trigger signal is used to trigger the modem terminal system to start a loopback detection function. The plurality of modems are devices that are in direct communicative connection with the modem termination system. Wherein the modem termination system is a Coaxial Modem Termination System (CMTS). The modem is a coaxial modem CM. Of course, it is not limited thereto, and the modem termination system and the modem may be other types of devices.
In some embodiments, before performing the step S101, the loopback processing method further includes the following steps: and when the modem terminal system detects that the received flow of the uplink channel exceeds a preset value in a preset time period, generating a loopback detection trigger signal. For example, when a loop is formed between one modem and another modem or the same modem is connected to the same bridge, network anomaly may be caused, and a large number of broadcast messages may be congested at the modem termination system. Therefore, as long as the modem terminal system detects that the received flow of the uplink channel exceeds the preset value in the preset time period, a loopback detection trigger signal is generated. The preset time is 10 seconds or 5 seconds, and the preset value is set according to the average flow of the modem terminal system. For example, when the modem is in normal operation and no loopback occurs, the flow rate of the modem per unit time is a1, and then when the flow rate per unit time suddenly exceeds n times, for example 3 times, of the a1, the loopback is determined to occur, and therefore, a loopback detection trigger signal needs to be generated.
In step S102, as shown in fig. 2, the modem terminal system 10 is connected to the modem 21, the modem 22, the modem 23, and the modem 24, respectively. In this case, the modems 21 and 22 loop back, and the modem 23 and 24 are normal. Thus, in this case, the initial detection message sent by the modem terminal system 10 to the modem 21 is returned to the modem terminal system 10 via the modem 22, and the initial detection message sent by the modem terminal system 10 to the modem 22 is returned to the modem terminal system 10 via the modem 21.
Therefore, the modem terminal system 10 detects the first detection message returned by the modem 21 and the modem 22. For example, the initial detection message is A1, the initial detection message becomes A1B1 after passing through the modem 21 and adding the identification information of the modem 21, and then becomes A1B2 after passing through the modem 22 and adding the identification information of the modem 22. The initial detection message passes through the modem 21, becomes A1B2 by adding the identification information of the modem 22, and then passes through the modem 21, becomes A1B2B1 by adding the identification information of the modem 21. The identification information of the first check packet A1B2 is B1B2, and the identification information of the second check packet A1B2B1 is B2B 1.
It will be appreciated that in some embodiments, it may also be that a single modem loops back due to the bridge itself, as shown in fig. 3. For example, the modem 21 loops due to accessing a bridge, so the initial detection message is A1, the initial detection message passes through the modem 21, and after adding the identification information of the modem 21, the initial detection message becomes A1B1, the modem 21 receives the first detection message returned by the modem 21, which is A1B1, and the identification information of the first detection message is B1.
In step S103, for example, if the first detection packet is A1B2, the extracted identification information is B1B2, and if the first detection packet is A1B1, the extracted identification information is B1.
In step S104, the upper and lower interfaces of the modem terminal system 10 and the corresponding modem may be directly disabled, or a disabling instruction may be sent to the corresponding modem, so that the modem disables the upper and lower interfaces. It will be appreciated that in some embodiments, the modem termination system 10 may delete upstream data from the corresponding modem based on the identification information.
In some embodiments, this step S104 includes: and disabling the modem terminal system and the uplink interface of the modem corresponding to the identification information according to the identification information.
In some embodiments, since the identification information includes first identification information of the at least two modems; the at least one first detection message comprises a plurality of first detection messages; therefore, this step S104 includes the following substeps: s1041, judging the first identification information of at least two looped modems according to the identification information in the first detection messages; s1042, according to the first identification information of the at least two modems, the uplink channel of the corresponding modem is forbidden. Wherein the upstream channels of both modems can be disabled.
As can be seen from the above, in the embodiment of the present application, when a loopback detection trigger signal is detected, an initial detection packet is broadcast to the plurality of modems; monitoring whether a first detection message returned by any modem is received, wherein the first detection message comprises the initial detection message and identification information of the modem forwarding the initial detection message; if at least one first detection message returned by any modem is received, extracting the identification information carried in each first detection message; disabling the uplink channel of the corresponding modem according to the identification information; therefore, the detection and the processing of the loopback of the modem are realized, and the system is prevented from being in failure.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a loopback processing device according to some embodiments of the present application. The apparatus is used in a modem termination system connected to a plurality of modems, the apparatus comprising: a broadcast module 201, a monitoring module 202, an extraction module 203, and a disabling module 204.
The broadcasting module 201 is configured to broadcast an initial detection packet to the plurality of modems when detecting a loopback detection trigger signal. The loopback trigger signal is used for triggering the modem terminal system to start a loopback detection function. The plurality of modems are devices that are in direct communicative connection with the modem termination system. Wherein the modem termination system is a Coaxial Modem Termination System (CMTS). The modem is a coaxial modem CM. Of course, it is not limited thereto, and the modem termination system and the modem may be other types of devices.
In some embodiments, the apparatus further comprises a generation module. The generation module is used for generating a loopback detection trigger signal when the modem terminal system detects that the received flow of the uplink channel exceeds a preset value in a preset time period. For example, when a loop is formed between one modem and another modem or the same modem is connected to the same bridge, network anomaly may be caused, and a large number of broadcast messages may be congested at the modem termination system. Therefore, as long as the modem terminal system detects that the received flow of the uplink channel exceeds the preset value in the preset time period, a loopback detection trigger signal is generated. The preset time is 10 seconds or 5 seconds, and the preset value is set according to the average flow of the modem terminal system. For example, when the modem is in normal operation and no loopback occurs, the flow rate of the modem per unit time is a1, and then when the flow rate per unit time suddenly exceeds n times, for example 3 times, of the a1, the loopback is determined to occur, and therefore, a loopback detection trigger signal needs to be generated.
The monitoring module 202 is configured to monitor whether a first detection packet returned by any of the modems is received, where the first detection packet includes the initial detection packet and identification information of the modem that forwards the initial detection packet. As shown in fig. 2, the modem termination system 10 is connected to the modem 21, the modem 22, the modem 23, and the modem 24, respectively. In this case, the modems 21 and 22 loop back, and the modem 23 and 24 are normal. Thus, in this case, the initial detection message sent by the modem terminal system 10 to the modem 21 is returned to the modem terminal system 10 via the modem 22, and the initial detection message sent by the modem terminal system 10 to the modem 22 is returned to the modem terminal system 10 via the modem 21.
Therefore, the modem terminal system 10 detects the first detection message returned by the modem 21 and the modem 22. For example, the initial detection message is A1, the initial detection message becomes A1B1 after passing through the modem 21 and adding the identification information of the modem 21, and then becomes A1B2 after passing through the modem 22 and adding the identification information of the modem 22. The initial detection message passes through the modem 21, becomes A1B2 by adding the identification information of the modem 22, and then passes through the modem 21, becomes A1B2B1 by adding the identification information of the modem 21. The identification information of the first check packet A1B2 is B1B2, and the identification information of the second check packet A1B2B1 is B2B 1.
It will be appreciated that in some embodiments it may also be the case that a single modem loops back due to the bridge itself. For example, the modem 21 loops due to accessing a bridge, so the initial detection message is A1, the initial detection message passes through the modem 21, and after adding the identification information of the modem 21, the initial detection message becomes A1B1, the modem 21 receives the first detection message returned by the modem 21, which is A1B1, and the identification information of the first detection message is B1.
The extracting module 203 is configured to extract the identification information carried in each first detection packet if at least one first detection packet returned by any modem is received. For example, if the first inspection packet is A1B2, the extracted identification information is B1B2, and if the first inspection packet is A1B1, the extracted identification information is B1.
The disabling module 204 is configured to disable an uplink channel of the corresponding modem according to the identification information. The upper and lower interfaces of the modem terminal system 10 with the corresponding modem may be directly disabled, or a disabling instruction may be sent to the corresponding modem so that the modem disables the upper and lower interfaces.
In some embodiments, the disabling module 204 is to: and disabling the modem terminal system and the uplink interface of the modem corresponding to the identification information according to the identification information.
In some embodiments, the disabling module 204 is to: and sending a disabling instruction to the corresponding modem according to the identification information so as to enable the corresponding modem to disable an uplink interface of the corresponding modem.
In some embodiments, the disabling module 204 is configured to determine, according to the identification information in the first detection messages, first identification information of at least two modems that loop back, and disable, according to the first identification information of the at least two modems, an uplink channel of the corresponding modem. Wherein the upstream channels of both modems can be disabled.
As can be seen from the above, in the embodiment of the present application, when a loopback detection trigger signal is detected, an initial detection packet is broadcast to the plurality of modems; monitoring whether a first detection message returned by any modem is received, wherein the first detection message comprises the initial detection message and identification information of the modem forwarding the initial detection message; if at least one first detection message returned by any modem is received, extracting the identification information carried in each first detection message; disabling the uplink channel of the corresponding modem according to the identification information; therefore, the detection and the processing of the loopback of the modem are realized, and the system is prevented from being in failure.
