Description

Technical Field

[0001] The present disclosure relates to the field of routers, and in particular to a router capable of providing a bridge mode. Background Art

[0002] In the bridge mode of the router, a public network IP address is assigned to a terminal device in the private network so that the terminal device in the private network can be identified by the device in the public network. By setting the bridge mode, the terminal device in the private network can share resources and exchange information with the device in the public network, so the terminal device can be used as a server, for example.

[0003] The function of the bridge mode can be provided by the Ethernet port in the router. For example, a user of a terminal device in a private network can connect the terminal device to the Ethernet port of the router and set the routing mode of the Ethernet port to the bridge mode, thereby utilizing the Ethernet port to implement the bridge function. Summary of the invention

[0004] With the continuous research and development of router functions, the types of ports that routers can provide are becoming more and more abundant. For example, in addition to Ethernet ports, routers can also include MoCA (Multimedia over Coax Alliance) ports, Wi-Fi (Wireless Fidelity) ports, and USB (Universal Serial Bus) ports. By connecting these ports on the router, terminal devices in the private network can also be connected to the network to realize the Internet access function of the terminal devices.

[0005] However, the inventors of the present disclosure have noticed that although the router can provide a variety of ports, other ports (such as MoCA ports, Wi-Fi ports, and USB ports, etc.) cannot directly provide the function of the bridge mode except the Ethernet port. Therefore, the diversity of the bridge mode of the router is limited. For example, a terminal device in a private network may not have an Ethernet interface but only a MoCA interface. In this case, the terminal device cannot realize the bridge function by connecting to the Ethernet port of the router.

[0006] The present disclosure provides a router, a method for a router, a computer-readable medium, and an apparatus, which can provide diversity of bridging modes, thereby providing users of terminal devices with more accurate bridging mode selection, improving usage convenience and enhancing user experience.

[0007] According to one aspect of the present disclosure, a router is provided. The router may include multiple ports; a memory having instructions stored thereon; and a processor configured to execute the instructions stored on the memory so that the router performs at least the following processing: obtaining a private network data packet from a private network via one of the multiple ports, and attaching identification information to the private network data packet, wherein the identification information indicates which port of the multiple ports of the router the private network data packet is obtained via; determining whether the port indicated by the identification information of the private network data packet is set to a bridge mode; in response to determining that the port indicated by the identification information of the first private network data packet obtained is set to a bridge mode, assigning a public network IP address to the first private network data packet; and sending the first private network data packet using the public network IP address.

[0016] In some embodiments, whether the port indicated by the identification information is set to a bridge mode is determined according to a preset bridge mode table, and the bridge mode table records a correspondence between at least one port among the multiple ports and the bridge mode.

[0017] In some embodiments, the method further comprises: storing the public network IP address in association with the private network IP address that is the source address of the first private network data packet.

[0031] The following detailed description is made with reference to the accompanying drawings, and the following detailed description is provided to assist in a comprehensive understanding of the various exemplary embodiments of the present disclosure. The following description includes various details to assist in understanding, but these details are considered to be examples only and not to limit the present disclosure, which is defined by the appended claims and their equivalents.

[0032] Figure 1 A schematic diagram showing multiple ports of a router 100 according to an embodiment of the present disclosure is shown.

[0033] like Figure 1 As shown, in some embodiments, the router 100 may include an Ethernet port 102, a MoCA port 104, a Wi-Fi port 106, and a USB port 108, which are respectively used to connect to the Ethernet interface, MoCA interface, Wi-Fi interface, and USB interface of a terminal device in a private network to provide corresponding functions.

[0034] The Ethernet port 102 may be a physical port configured on the router 100, for example, connected to and communicated with the Ethernet port of the terminal device through a network cable. The MoCA port 106 may be a physical port configured on the router 100, for example, connected to and communicated with the MoCA interface of the terminal device through a coaxial cable. The USB port 108 may be a physical port configured on the router 100, for example, connected to and communicated with the USB port of the terminal device through a USB cable.

[0035] It should be understood that although Figure 1 The example shows that the router 100 includes an Ethernet port 102, a MoCA port 104, a Wi-Fi port 106, and a USB port 108. The router according to the embodiment of the present disclosure does not need to include all of the above ports. In addition, according to user needs, the router according to the embodiment of the present disclosure can also be configured to include other ports different from the above ports.

[0036] in addition, Figure 1The number of the Ethernet port 102, the MoCA port 104, the Wi-Fi port 106, and the USB port 108 illustrated in the example is one, but multiple Ethernet ports 102, multiple MoCA ports 104, multiple Wi-Fi ports 106, and / or multiple USB ports 108 can be configured in the router 100 according to user needs, etc., to achieve connection and communication with more terminal devices.

[0037] Figure 2 A block diagram illustrating an exemplary configuration of the router 100 according to an embodiment of the present disclosure is illustrated. Figure 2 The router 100 may correspond to Figure 1 The router 100 shown in FIG. 1 includes Figure 1 One or more of the multiple ports shown in .

[0038] Although referred to herein as a router, the router 100 may be, for example, a hardware electronic device capable of combining the functionality of a modem, an access point, and / or a router. The present disclosure also contemplates that the router 100 may include, but is not limited to, the functionality of an IP / QAM set-top box (STB) or a smart media device (SMD) capable of decoding audio / video content and playing content provided by an OTT or MSO.

[0039] like Figure 2 As shown, the router 100 includes a user interface 20, a network interface 21, a power supply 22, a WAN interface 23, a memory 24, and a controller 26. The user interface 20 may include, but is not limited to, buttons, keyboards, keypads, LCDs, CRTs, TFTs, LEDs, HDs, or other similar display devices, including display devices with touch screen capabilities that enable interaction between a user and a gateway device. The network interface 21 may include various network cards and circuit systems implemented in software and / or hardware to enable communication with a wireless extender device and a client device using a wireless protocol, such as any IEEE 802.11 Wi-Fi protocol, Bluetooth protocol, Bluetooth Low Energy (BLE), or other short-range protocols operating according to wireless technology standards for exchanging data over a short distance using any licensed or unlicensed frequency band (such as a Citizen Broadband Radio Service (CBRS) band, a 2.4 GHz band, a 5 GHz band, or a 6 GHz band), an RF4CE protocol, a ZigBee protocol, a Z-Wave protocol, or an IEEE 802.15.4 protocol.

[0040] The power supply 22 provides power to the internal components of the router 100 via the internal bus 27. The power supply 22 may be a self-contained power supply, such as a battery pack, whose interface is powered by a charger connected to an outlet (e.g., directly or through other devices). The power supply 22 may also include a rechargeable battery that is removable for replacement, such as a NiCd, NiMH, Li-ion, or Li-pol battery. The WAN interface 23 may include various network cards and circuit systems implemented in software and / or hardware to enable communication between the router device and an Internet service provider or a multiple system operator (MSO).

[0041] The memory 24 includes a single memory or one or more memories or storage locations, including but not limited to random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), EPROM, EEPROM, flash memory, logic blocks of an FPGA, a hard disk, or any other layers of the memory hierarchy. The memory 24 can be used to store any type of instructions, software, or algorithms, including software 25 for controlling the general functions and operations of the router 100.

[0042] The controller 26 controls the general operation of the router 100 and performs management functions related to other devices in the network, such as extenders and client devices. The controller 26 may include, but is not limited to, a CPU, a hardware microprocessor, a hardware processor, a multi-core processor, a single-core processor, a microcontroller, an application-specific integrated circuit (ASIC), a DSP, or other similar processing device, capable of executing any type of instructions, algorithms, or software for controlling the operation and functions of the router 100 according to the embodiments described in the present disclosure. The controller 26 may be various implementations of digital circuit systems, analog circuit systems, or mixed signal (a combination of analog and digital) circuit systems that perform functions in a computing system. The controller 26 may include, for example, an integrated circuit (IC), a portion or circuit of a separate processor core, an entire processor core, a separate processor, a programmable hardware device such as a field programmable gate array (FPGA), and / or a system including multiple processors.

[0043] Internal bus 27 may be used to establish communications between components of router 100 (eg, 20 - 22 , 24 , and 26 ).

[0044] Figure 3 FIG. 3 is a flow chart showing a method 300 for a router according to an embodiment of the present disclosure. The method 300 can be used, for example, to Figure 1 and 2 The router 100 shown in FIG. Figure 2 and Figure 3 A router and a method for a router according to an embodiment of the present disclosure are described in detail.

[0045] like Figure 3 As shown, in step S302, the controller 26 obtains a private network data packet from the private network, and adds identification information to the private network data packet, wherein the identification information indicates through which port of the multiple ports of the router the private network data packet is obtained.

[0046] It should be understood that the private network described in the present disclosure is a network space in a local area, such as a local area network (LAN), which can be set up in a home, office or factory. Terminal devices in the private network (such as personal computers, smart phones, televisions and other electronic devices) can share resources and exchange information through the private network. In addition, the private network is logically isolated from other networks (other private networks, public networks, etc.), and terminal devices in the private network cannot communicate directly with devices in other networks, but need to communicate with the help of router functions. In addition, the public network is, for example, a wide area network (WAN) such as the Internet.

[0047] In some embodiments, the controller 26 may obtain multiple private network data packets from the private network, such as PR1, PR2, PR3, PR4, ... The multiple private network data packets may be, for example, received through Figure 1 The private network packets are received by one or more of the ports 102 to 108 of the router 100. In some embodiments, the controller 26 may be configured to receive the private network packets from each of the ports 102 to 108 of the router.

[0048] In some embodiments, the controller 26 may attach corresponding identification information to the private network data packets (e.g., PR1, PR2, PR3, PR4). The following Table 1 illustrates the identification information attached by the controller 26 to multiple private network data packets, wherein the identification information "00" indicates that PR1 is obtained via the Ethernet port of the router, the identification information "01" indicates that PR2 is obtained via the MoCA port of the router, the identification information "10" indicates that PR3 is obtained via the Wi-Fi port of the router, and the identification information "11" indicates that PR4 is obtained via the USB port of the router.

[0049] (Table 1)

[0050] Private network packets Identification Information Identify the port indicated by the information PR1 00 Ethernet Port PR2 01 MoCA Port PR3 10 Wi-Fi Port PR4 11 USB Port

[0051] In the above Table 1, the identification information includes 2 bits of binary information to distinguish the four different ports of the router. In the case where the number of ports included in the router 100 is greater, more bits may be used to represent the identification information. In addition, the identification information may also be represented in other ways, and the present disclosure does not limit the form of the identification information.

[0052] In some embodiments, the identification information may be attached to the header of the private network data packet, so that the controller 26 can easily obtain the identification information. It should be understood that in the present disclosure, the location where the identification information is attached to the private network data packet is not particularly limited, and those skilled in the art can flexibly design it according to the specific frame format of the data packet.

[0053] In step S304 , the controller 26 determines whether the port indicated by the identification information of the private network data packet is set to a bridge mode.

[0054] In some embodiments, the controller 26 can determine whether the port indicated by the identification information of the private network data packet is set to the bridge mode according to a preset bridge mode table. The bridge mode table, for example, records the correspondence between at least one of the multiple ports of the router and the bridge mode.

[0055] Table 2 below illustrates a bridging mode table according to an embodiment of the present disclosure, wherein the corresponding port is indicated by identification information. In some embodiments, for example, when the controller 26 obtains PR1 and adds identification information "00" (Ethernet port) to PR1, the controller 26 determines that the bridging mode corresponding to the Ethernet port indicated by the identification information "00" is "not enabled" according to Table 2. In this case, the controller 26 determines that the data packet PR1 is not a data packet to be bridged, so that, for example, the bridging operation can be terminated.

[0056] In addition, when the controller 26 obtains PR2 and adds identification information "01" (MoCA port) to PR2, the controller 26 determines that the bridge mode corresponding to the MoCA port indicated by the identification information "01" is in the "enabled" state according to Table 2. In this case, the controller 26 will use this information to perform the corresponding IP address allocation operation related to the bridge mode described later.

[0057] (Table 2)

[0058] Identification Information Bridge Mode 00(Ethernet port) Not enabled 01(MoCA port) Enable 10 (Wi-Fi port) Not enabled 11 (USB port) Enable

[0059] It should be understood that the correspondence between all ports of the router and the bridge mode is recorded in the above Table 2. In some embodiments, only the ports with the bridge mode "enabled" may be recorded to save storage space.

[0060] In some embodiments, the bridge mode table can be pre-set by the user of the private network. For example, when the user wants to use the bridge mode for his terminal device, he can set the port (e.g., MoCA port) of the router 100 to which the terminal device is to be connected through a GUI (Graphical User Interface) or an application in the form of a web, and set the bridge function of the port to "enable". The user connects the terminal device to the port of the router 100 set with the bridge mode, and the bridge mode function can be realized.

[0061] In other embodiments, the bridge mode table may be pre-set by a network service provider. For example, the network service provider may help the user pre-set the port (e.g., MoCA port) of the router 100 to which the user's terminal device is to be connected, and set the bridge function of the port to "enable" according to the user's needs. In some embodiments, the network service provider may set the bridge mode table through, for example, SNMP (Simple Network Management Protocol) or CWMP (CPE WAN Management Protocol, also known as TR069).

[0062] In addition, in some embodiments, the user or the network service provider may also set the port of the router to which the terminal is to be connected to as "disabled" by a method similar to the above, so as not to use the bridging function.

[0063] In some embodiments, the bridge mode table may be stored in the memory 24 of the router 100, for example, for the controller 26 to search and use. In some embodiments, the bridge mode tables of multiple routers may also be stored in an external server or cloud storage, and each router obtains its own bridge mode table by querying the external server or cloud storage.

[0064] In step S306 , in response to determining that the port indicated by the identification information of the acquired first private network data packet (eg, PR2 ) is set to a bridge mode, the controller 26 allocates a public network IP address to the first private network data packet.

[0065] In some embodiments, for example, when the controller 26 determines that the port (MoCA port) indicated by the identification information "01" of PR2 is set to the bridge mode (set to "enabled" in Table 2), the controller 26 sends a DHCP DISCOVER broadcast packet to the DHCP (Dynamic Host Configuration Protocol) server to request a leased IP address. Next, the controller 26 selects a DHCPOFFER packet from the DHCP OFFER packets received from the DHCP server, and uses the IP address provided in the DHCP OFFER packet as the public network IP address to be allocated to PR2. In addition, the controller 26 broadcasts a DHCP REQUEST message packet to the network, indicating that the IP address provided by a DHCP server has been accepted, so that all other DHCP servers can revoke the IP addresses they provide so as to provide the IP address for the next IP lease request. Thus, the controller 26 allocates a public network IP address to PR2.

[0066] In step S308 , the controller 26 sends the first private network data packet using the public network IP address allocated by the controller 26 .

[0067] In some embodiments, the first private network data packet (eg, PR2 ) may be sent to the public network through the WAN port of the router 100 using the public network IP address assigned by the controller 26 .

[0068] According to the router disclosed in the present invention, the bridging mode can be set for any port among the multiple ports, thereby providing diversity of bridging modes, providing users of terminal devices with more accurate bridging mode selection, improving ease of use and enhancing user experience.

[0069] In some embodiments, the multiple ports of the router may include, for example, at least two of an Ethernet port, a MoCA port, a Wi-Fi port, and a USB port. Thus, the router according to the present disclosure can provide bridging modes for different ports respectively, and can also provide bridging mode for the user's terminal device when, for example, the user's terminal device only has an interface that matches one of the ports (for example, only a MoCA interface, etc.). In addition, since the router according to the present disclosure can provide a variety of bridging modes, the user can freely choose which port to use to implement the bridging mode according to the convenience of use, the interface of the terminal device, etc., thereby providing the user of the terminal device with a more accurate choice of bridging mode, improving the convenience of use and enhancing the user experience.

[0070] In some embodiments, the multiple ports of the router may also include, for example, multiple Ethernet ports, multiple MoCA ports, multiple Wi-Fi ports, or multiple USB ports. For example, when the multiple ports of the router include multiple (e.g., two) MoCA ports, different identification information may be added to the private network data packets obtained via the two MoCA ports to distinguish the two MoCA ports. According to this embodiment, a richer selection of interfaces can be provided, providing bridging functions for more terminal devices.

[0071] In some embodiments, multiple private network data packets from a private network obtained via different ports of a router use the same subnet. For example, the private network data packets PR2 and PR4 described above are obtained from a MoCA port and a USB port, respectively. For these two data packets PR2 and PR4, since the identification information "01" and "10" corresponding to the MoCA port and the USB port are respectively attached, the same subnet resources can be used without conflict, thereby saving network resources. In some embodiments, the private network data packets obtained via multiple ports can all use the same subnet as the Ethernet port. Thus, the diversity of bridging modes can be achieved without occupying new network resources.

[0072] In some embodiments, when the Wi-Fi port of the router is used to implement the bridge mode, the first frequency band (for example, one of the 2.4 GHz band, the 5 GHz band, or the 6 GHz band) can be used for a certain terminal device to implement the bridge mode, and the second frequency band (for example, another of the 2.4 GHz band, the 5 GHz band, or the 6 GHz band) can be used for other terminal devices to implement the normal Internet access function. In this way, the bridge mode and the normal Internet access function can be implemented at the same time without causing conflicts in network resources.

[0073] Next, refer to Figure 4 An exemplary flow chart of a method 400 for a router according to another embodiment of the present disclosure is described. The method 400 can be used, for example, as follows: Figure 2 In the method 400, steps S302 to S308 are similar to those in the reference Figure 3 The method 300 described in the present invention is the same as that described in the present invention, so the same reference numerals are added and the description is omitted. Figure 3 The method 300 in step S402 is different.

[0074] like Figure 4 As shown, in some embodiments, in step S402, the public network IP address assigned by the controller 26 in step S306 may be stored in association with the private network IP address that is the source address of the first private network data packet (eg, PR2). Figure 4 In the embodiment, step S402 is illustrated as being executed after step S308, but may also be executed before step S308 and after step S306.

[0075] Table 3 below illustrates two stored public network IP addresses and two private network IP addresses associated therewith. The private network IP addresses "192.168.1.100" and "192.168.1.200" correspond to two terminal devices in the private network, respectively, while the public network IP addresses "122.108.24.100" and "122.108.24.200" represent the public network IP addresses allocated to the two terminal devices.

[0076] (Table 3)

[0077] Private network IP address Public network IP address 192.168.1.100 122.108.24.100 192.168.1.200 122.108.24.200

[0078] In some embodiments, the public network IP address and the private network IP address associated therewith may be stored in the memory 24 of the router 100, for example. In some embodiments, the public network IP addresses and the private network IP addresses associated therewith of multiple routers may also be stored in an external server or cloud storage, and each router obtains the required information by querying the external server or cloud storage.

[0079] In some embodiments, when the source address of the second private network data packet obtained by the controller 26 matches the stored private network IP address, and the controller 26 determines that the port indicated by the identification information of the second private network data packet is set to bridging mode, the second private network data packet is sent using the public network IP address associated with the stored private network IP address.

[0080] For example, when the source address of the second private network data packet is "192.168.1.100", it is the same as the private network IP address "192.168.1.100" stored in Table 3, indicating that the sending source (terminal device) of the second private network data packet has previously sent a data packet to the router, and the router has assigned the public network IP address "122.108.24.100" to the sending source. In addition, the controller 26 determines that the port indicated by the identification information of the second private network data packet is set to bridge mode, indicating that the data packet is sent through the port set to bridge mode, and the function of bridge mode needs to be implemented. In this case, the second private network data packet is sent using the public network IP address "122.108.24.100" that has been previously assigned to the sending source.

[0081] As a result, there is no need to reallocate the public network IP address each time a private network data packet is obtained, which saves computing overhead and network resources and improves the efficiency of data packet sending.

[0082] Next, refer to Figure 5 An exemplary flow chart of a method 500 for a router according to another embodiment of the present disclosure is described. The method 500 can be used, for example, to Figure 2 In the method 500, steps S302 to S308 are similar to those in the reference Figure 3 The method 300 described above is the same as that described above, and step S402 is the same as that described above. Figure 4 The method 400 described in the present invention is the same as that described in the present invention, so the same reference numerals are added and the description is omitted. Figure 3 Method 300 and Figure 4 The method 400 in different steps S502 and S504.

[0083] like Figure 5 As shown, in some embodiments, in step S502, a public network data packet from a public network may be obtained. This step S502 may also be performed by Figure 2 The controller 26 shown implements.

[0084] In some embodiments, the public network data packet is a data packet sent from a terminal device in a public network to a terminal device in a private network. The source address of the public network data packet indicates the public network IP address of the terminal device in the public network. In addition, since the terminal device in the public network cannot know the private network IP address of the terminal device in the private network, the destination address of the public network data packet only indicates the public network IP address, and the public network IP address needs to be converted into the private network IP address through the bridging function of the router, so as to provide the public network data packet to the terminal device in the private network.

[0085] In step S504, when the public network IP address as the destination address of the public network data packet matches the stored public network IP address, the public network data packet is sent using the private network IP address associated with the stored public network IP address.

[0086] For example, when the destination address of the public network data packet is "122.108.24.200", it is the same as the public network IP address "122.108.24.200" in Table 3. Therefore, the private network IP address "192.168.1.200" associated with the public network IP address is used to send the public network data packet to the terminal device in the private network corresponding to the above private network IP address.

[0087] As a result, terminal devices in the private network can receive data packets from the public network through the bridging function of the router.

[0088] Next, refer to Figure 6 An exemplary configuration block diagram of another electronic device 600 that can implement the embodiments of the present disclosure is described. For example, the electronic device 600 can be used to implement one or more of the methods 300 to 500 according to the embodiments of the present disclosure.

[0089] like Figure 6 As shown, the electronic device 600 includes a processing subsystem 610, a memory subsystem 612, and a networking subsystem 614.
