Description

Technical Field

[0002] The number of fixed broadband users in China exceeds 400 million households, and the number of client devices accessing home gateways is even larger. There is an endless variety of types of intelligent home gateways, and various different types of intelligent home gateways provide users with many different types of management and configuration services, such as Internet bandwidth management, black and white list management, wireless channel password management, wireless power management, wireless roaming management, wireless networking management, gateway energy-saving management, gateway usage status management, etc. This series of services defines the gateway as an intelligent gateway, and its essence is to improve the Internet experience and enable users to more simply enjoy higher-quality network services.

[0003] Although current intelligent home gateways can provide many convenient management methods, when users face the network performance of the gateway, they still have a passive experience method. Users cannot solve the problems of accidental disconnection and delay that occur during Internet access.

[0004] In summary, existing intelligent home gateways have some deficiencies. For example, they passively respond to users' higher requirements for network performance and require users to configure the functions of the intelligent gateway by themselves. However, the intelligent home gateway cannot actively improve network performance and cannot actively solve the problems of disconnection and delay that occur when users use the Internet services of the gateway. Summary of the Invention

Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0066] Please refer to Figures 1 to 4 , the present invention first provides an intelligent gateway configuration method, including the following steps:

[0067] Step S1: Set response variables corresponding to each Domain Name System (DNS) entry, low signal statistics variables and disconnection statistics variables of the client's wireless workstations, and online duration statistics variables of the client in the gateway's configuration data;

[0068] Specifically, as Figure 1 shown, in the intelligent gateway configuration method of the present invention, the client is connected to the Internet through the gateway. The client includes a wired client and a wireless client. The user can enable the active network improvement function of the gateway through a web page. When this function is turned on, the gateway will actively improve the network performance from three aspects: DNS entries, wireless network signal strength, and the online duration of the client, and actively solve the disconnection and latency problems that occur when the user uses the Internet service of the gateway, improving the user's network usage experience. The specific improvement methods will be described in detail later.

[0069] Step S2: Use the response variables of each DNS entry to count the query times of each DNS entry, and increase the TTL value corresponding to the DNS entry when the query times of the DNS entry reach a preset query times threshold.

[0070] Among them, step S2 mainly improves the network performance from the perspective of the query frequency (query times) of DNS entries, and is applicable to both wired clients and wireless clients. Specifically, it is to count the query times of DNS entries and increase the Time To Live (TTL) value of the DNS entry with more query times, so as to achieve the purpose of improving the network performance.

[0071] In detail, step S2 specifically includes:

[0072] When finding a corresponding DNS entry domain name match in the DNS cache structure, increment by 1 the corresponding response variable of the DNS entry, where the value of the corresponding response variable of the DNS entry is equal to the query count of the DNS entry;

[0073] When the response variable of a DNS entry reaches a preset query count threshold, write the DNS entry into a preset high query frequency file, and at the same time increase the TTL value in the response packet of the DNS entry.

[0074] Furthermore, as Figure 2 shown, in some embodiments of the present invention, methods for improving network performance from the perspective of the query frequency (query count) of DNS entries include:

[0075] Enable the DNSmasq tool and add the response variable answer_cnt of each DNS entry to the DNS cache structure;

[0076] When finding a domain name match in the DNS cache, increment by 1 the response variable answer_cnt of the corresponding DNS entry;

[0077] Determine whether the response variable answer_cnt of each DNS entry reaches the query count threshold;

[0078] If the query count threshold is reached, write the information of the DNS entry into the high query frequency file, i.e., the / var / DNS_high file, and display the information of the DNS entry on the gateway page. At the same time, increase the TTL value in the response packet of the DNS entry to 60 minutes.

[0079] Step S3: Use the wireless workstation low signal statistical variable and disconnection statistical variable of the client to count the number of times the wireless signal strength of each client is lower than a preset wireless signal strength threshold and the number of times each client disconnects. When the number of times the wireless signal strength of the client is lower than the preset wireless signal strength threshold reaches and the number of times the client disconnects meets a preset wireless signal adjustment condition, adjust the wireless channel and transmission rate of the client.

[0080] Among them, step S3 mainly improves network performance from the perspective of wireless network signal strength, only for wireless clients connected to the gateway through the wireless network, not for wired clients. Specifically, it is to count the number of times the wireless network signal strength is too low or the number of disconnections, and when the number reaches the limit, control the gateway to adjust the wireless channel and transmission rate of the client to enhance the wireless network for the client.

[0081] Specifically, step S3 specifically includes:

[0082] When the wireless workstation of the client sends a disassociation request, the disconnection statistical variable is incremented by 1.

[0083] When the wireless received signal strength of the wireless workstation of the client is lower than the set threshold, the low signal statistical variable is incremented by 1.

[0084] When the disconnection statistical variable of the wireless workstation of the client reaches the preset disconnection threshold and the low signal statistical variable reaches the preset low signal threshold, the wireless workstation is written into the file with poor wireless signal quality, and at the same time, the wireless channel and transmission rate of the wireless workstation are adjusted.

[0085] Furthermore, as Figure 3 shown, in some embodiments of the present invention, the method for improving network performance from the perspective of wireless network signal strength specifically includes:

[0086] Enable the Wireless Local Area Network (WLAN) driver.

[0087] Add the low signal statistical variable rssi_disconnect_cnt and the disconnection statistical variable cancel_disconnect_cnt to the wireless workstation structure.

[0088] When the wireless workstation of the client sends a disassociation request, cancel_disconnect_cnt is incremented by 1.

[0089] When the wireless received signal strength (RSSI) of the wireless workstation of the client is lower than the set threshold, rssi_disconnect_cnt is incremented by 1.

[0090] When the cancel_disconnect_cnt of the wireless workstation of the client reaches the disconnection threshold and rssi_disconnect_cnt reaches the low signal threshold;

[0091] The wireless workstation of the client is written into the file with poor wireless signal quality, that is, the / var / RSSI_low file, and at the same time, the wireless workstation of the client is displayed on the gateway page, and at the same time, the wireless channel and transmission rate of the wireless workstation are adjusted.

[0092] Specifically, the adjustment of the wireless channel and transmission rate of the wireless workstation specifically includes:

[0093] The wireless driver enables automatic channel scanning and reselects the channel.

[0094] The wireless driver increases the radio frequency transmission power.

[0095] Wireless driver switches working modes, from 802.11ac to 802.11n, and from 802.11n to 802.11g.

[0096] Step S4: Use the online duration statistical variable of the client to count the online duration of the client, read the CPU usage rate, memory usage rate, and network connection number of the gateway. When the CPU usage rate, memory usage rate, and network connection number of the gateway meet the preset priority conditions, control the gateway to preferentially connect to the client with a longer online duration.

[0097] Among them, step S4 mainly improves network performance from the perspective of the online duration of the client. For both wired and wireless clients, specifically, it counts the online duration of the client, and when the CPU usage rate, memory usage rate, and network connection number of the gateway reach the limit values, it controls the gateway to preferentially connect to the client with a longer online duration to ensure the network usage experience of the client with a longer online duration.

[0098] Specifically, as Figure 4 described, in some embodiments of the present invention, step S4 specifically includes:

[0099] Create a Dynamic Host Configuration Protocol (DHCP) lease reading polling thread

[0100] Read the DHCP service lease file according to a preset reading period

[0101] Extract the Media Access Control (Mac) address and Internet Protocol (IP) address from the lease file and write them into the Mac_list linked list

[0102] When the Mac address exists in the Mac_list linked list, the online duration statistical variable online_cnt of the client corresponding to the Mac address is incremented by 1

[0103] Read the Central Processing Unit (CPU) usage rate, memory usage rate, and network connection number of the gateway. When the CPU usage rate, memory usage rate, and network connection number of the gateway reach the preset gateway CPU usage rate threshold, memory usage rate threshold, and network connection number threshold respectively;

[0104] Read the Mac_list linked list and select the Mac address corresponding to the client with the largest online duration statistical variable;

[0105] Use the Quality of Service (QOS) service to control the gateway to preferentially connect to this Mac address.

[0106] Further, step S4 further includes, while using the Quality of Service (QOS) service to control the gateway to preferentially connect to this Mac address, writing this Mac address into the online duration statistics file, that is, the / var / online_high file, and displaying this Mac address on the gateway page.

[0107] In some embodiments of the present invention, for the QOS priority queue: in the priority queue PQ, there are four priority queues: high, medium, normal, and low. The data packets of the client are placed in different queues according to the implementation definition, and the router serves in the order of high, medium, normal, and low. Only when the high-priority queue is empty, will it serve other priority queues, and so on. In this way, it can ensure that high-priority clients are definitely served first.

[0108] Please refer to Figure 5 , the present invention also provides an intelligent gateway device, including:

[0109] A setting unit 100, configured to set response variables corresponding to each DNS entry, a low-signal statistics variable and a disconnection statistics variable of the client's wireless workstation, and an online duration statistics variable of the client in the configuration data of the gateway;

[0110] A DNS awareness and improvement module 200, configured to use the response variables of each DNS entry to count the query times of each DNS entry, and when the query times of the DNS entry reach a preset query times threshold, increase the TTL value corresponding to this DNS entry;

[0111] A wireless awareness and improvement module 300, configured to use the low-signal statistics variable and the disconnection statistics variable of the client's wireless workstation to count the number of times the wireless signal strength of each client is lower than a preset wireless signal strength threshold and the number of times each client disconnects, and when the number of times the wireless signal strength of the client is lower than the preset wireless signal strength threshold and the number of times the client disconnects meet a preset wireless signal adjustment condition, adjust the wireless channel and transmission rate of this client;

[0112] An online awareness and improvement module 400, configured to use the online duration statistics variable of the client to count the online duration of the client, read the CPU usage rate, memory usage rate, and network connection number of the gateway, and when the CPU usage rate, memory usage rate, and network connection number of the gateway meet a preset priority condition, control the gateway to preferentially connect to the client with a longer online duration.

[0113] Specifically, as Figure 1 shown, in the intelligent gateway configuration device of the present invention, the client is connected to the Internet through the gateway. The client includes a wired client and a wireless client. The user can enable the active Internet improvement function of the gateway through a web page. When this function is turned on, the gateway will actively improve the network performance from three aspects: DNS entries, wireless network signal strength, and the online duration of the client, and actively solve the problems of disconnection and delay that occur when the user uses the Internet service of the gateway, improving the user's network usage experience. The specific improvement method will be described in detail later.

[0114] Among them, the DNS perception and improvement module 200 mainly improves the network performance from the perspective of the query frequency (number of queries) of DNS entries. At the same time, for wired clients and wireless clients, specifically, it counts the number of queries of DNS entries and increases the Time To Live (TTL) value of the DNS entries with more queries, thereby achieving the purpose of improving network performance.

[0115] In detail, the specific working process of the DNS perception and improvement module 200 includes:

[0116] When finding a match for the domain name of the corresponding DNS entry in the DNS cache structure, increment the corresponding response variable of the DNS entry by 1. The value of the corresponding response variable of the DNS entry is equal to the number of queries of the DNS entry;

[0117] When the response variable of the DNS entry reaches the preset query count threshold, write the DNS entry into the preset high query frequency file, and at the same time increase the TTL value in the response packet of the DNS entry.

[0118] Further, as Figure 2 shown, in some embodiments of the present invention, the process of improving network performance from the perspective of the query frequency (number of queries) of DNS entries includes:

[0119] Start the DNSmasq tool and add the response variable answer_cnt of each DNS entry to the DNS cache structure;

[0120] When finding a match for the domain name in the DNS cache, increment the response variable answer_cnt of the corresponding DNS entry by 1;

[0121] Judge whether the response variable answer_cnt of each DNS entry reaches the query count threshold;

[0122] If the query count threshold is reached, the information of the DNS entry is written to the high query frequency file, i.e., the / var / DNS_high file, and the information of the DNS entry is displayed on the gateway page. At the same time, the TTL value in the response packet of the DNS entry is increased to 60 minutes.

[0123] Among them, the wireless sensing and improvement module 300 mainly improves the network performance from the perspective of the wireless network signal strength, only for wireless clients connected to the gateway through the wireless network, not for wired clients. Specifically, it counts the number of times when the wireless network signal strength is too low or the connection is dropped, and when the number reaches the limit, it controls the gateway to adjust the wireless channel and transmission rate of the client to enhance the wireless network for the client.

[0124] Specifically, the working process of the wireless sensing and improvement module 300 specifically includes:

[0125] When the wireless workstation of the client sends a disassociation request, the disconnection statistics variable is incremented by 1;

[0126] When the wireless received signal strength of the wireless workstation of the client is lower than the set threshold, the low signal statistics variable is incremented by 1;

[0127] When the disconnection statistics variable of the wireless workstation of the client reaches the preset disconnection threshold and the low signal statistics variable reaches the preset low signal threshold, the wireless workstation is written into the file with poor wireless signal quality, and at the same time, the wireless channel and transmission rate of the wireless workstation are adjusted.

[0128] Further, as Figure 3 shown, in some embodiments of the present invention, the method for improving the network performance from the perspective of the wireless network signal strength specifically includes:

[0129] Enable the Wireless Local Area Network (WLAN) driver;

[0130] Add the low signal statistics variable rssi_disconnect_cnt and the disconnection statistics variable cancel_disconnect_cnt to the wireless workstation structure;

[0131] When the wireless workstation of the client sends a disassociation request, cancel_disconnect_cnt is incremented by 1;

[0132] When the wireless received signal strength (RSSI) of the wireless workstation of the client is lower than the set threshold, rssi_disconnect_cnt is incremented by 1;

[0133] When the cancel_disconnect_cnt of the wireless workstation of the client reaches the disconnection threshold and the rssi_disconnect_cnt reaches the low signal threshold;

[0134] Write the wireless workstation of the client into the file with poor wireless signal quality, that is, the / var / RSSI_low file. At the same time, the wireless workstation of the client is displayed on the gateway page, and the wireless channel and transmission rate of the wireless workstation are adjusted.

[0135] Specifically, the adjustment of the wireless channel and transmission rate of the wireless workstation specifically includes:

[0136] The wireless driver enables automatic channel scanning and reselects the channel;

[0137] The wireless driver increases the radio frequency transmission power;

[0138] The wireless driver switches the working mode from 802.11ac to 802.11n, and from 802.11n to 802.11g.

[0139] Among them, the online perception and improvement module 400 mainly improves the network performance from the perspective of the online duration of the client. At the same time, for wired clients and wireless clients, specifically, it is to count the online duration of the client, and when the CPU usage rate, memory usage rate and network connection number of the gateway reach the limit values, control the gateway to give priority to connecting the client with a longer online duration to ensure the network usage experience of the client with a longer online duration.

[0140] Specifically, as Figure 4 described, in some embodiments of the present invention, the method for improving the network performance from the perspective of the online duration of the client specifically includes:

[0141] Create a Dynamic Host Configuration Protocol (DHCP) lease reading polling thread

[0142] Read the DHCP service lease file according to a preset reading period

[0143] Extract the Media Access Control (Mac) address and Internet Protocol (IP) address from the lease file and write them into the Mac_list linked list

[0144] When the Mac address exists in the Mac_list linked list, the online duration statistical variable online_cnt of the client corresponding to the Mac address is incremented by 1

[0145] Read the usage rate of the Central Processing Unit (CPU), memory usage rate, and the number of network connections of the read gateway. When the CPU usage rate, memory usage rate, and the number of network connections of the gateway reach the preset gateway CPU usage rate threshold, memory usage rate threshold, and the number of network connections threshold respectively;

[0146] Read the Mac_list linked list and select the Mac address corresponding to the client with the largest online duration statistical variable;

[0147] Use the Quality of Service (QOS) service to control the gateway to preferentially connect to this Mac address.

[0148] Further, the step S4 further includes, while using the Quality of Service (QOS) service to control the gateway to preferentially connect to this Mac address, writing this Mac address into the online duration statistical file, that is, the / var / online_high file, and displaying this Mac address on the gateway page.

[0149] In some embodiments of the present invention, for the QOS priority queue: in the priority queue PQ, there are four priority queues: high, medium, normal, and low. The data packets of the client are placed in different queues according to the implementation definition, and the router serves in the order of high, medium, normal, and low. Only when the high-priority queue is empty, will it serve other priority queues, and so on. In this way, it can ensure that high-priority clients are definitely served first.
