Network access method, system and optical line terminal

Abstract

This application provides a network access method, system, and optical line terminal (OLT), relating to the field of communication technology. The network access method involves an OLT receiving a network access request from a terminal device, wherein the network access request carries the URL of the network to be accessed. When the URL of the network to be accessed is an intranet URL, the OLT sequentially sends the network access request to a first server associated with the URL of the network to be accessed through a first port module and an intranet access system. The OLT then sequentially receives a first response data packet from the first server based on the network access request through the intranet access system and the first port module. Finally, the OLT sends the first response data packet to the terminal device. The OLT possesses both intranet and extranet access capabilities in addition to its existing extranet access functionality. This eliminates the need for additional optical transport network (OTN) equipment, saving on equipment cost and space. Furthermore, the OLT's intranet and extranet access functions are independent of each other.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a network access method, system and optical line terminal. Background Technology

[0002] Typically, a corporate campus includes both companies that need access to the external network and companies that need access to the internal network. To meet the network needs of the companies in the campus, network operators need to install optical line terminal (OLT) equipment for accessing the external network and optical transport network (OTN) equipment for accessing the internal network in the computer room.

[0003] Because it requires setting up both an OLT device and an OTN device in the computer room, the cost is high, the space occupied is large, and the power consumption is also high. Summary of the Invention

[0004] This application provides a network access method, system, and optical line terminal to solve the problems of high cost, large footprint, and high power consumption that require setting up two devices, OLT and OTN, in the computer room in the prior art.

[0005] Firstly, this application provides a network access method applied to an optical line terminal (OLT), the OLT including a first port module for accessing an intranet. The method includes: the OLT receiving a network access request from a terminal device, wherein the network access request carries the URL of the network to be accessed; when the URL of the network to be accessed is an intranet URL, the OLT sequentially sends the network access request to a first server associated with the URL of the network to be accessed through the first port module and the intranet access system; the OLT sequentially receives a first response data packet from the first server based on the network access request through the intranet access system and the first port module; and the OLT sends the first response data packet to the terminal device.

[0006] In one alternative implementation, the first port module is a point-to-multipoint (P2MP) board.

[0007] Understandably, point-to-multipoint (P2MP) cards can access the intranet, thereby enabling the OLT to access the intranet.

[0008] In one optional implementation, the first port module includes a main port and a backup port. The OLT sequentially sends a network access request to a first server associated with the URL of the network to be accessed through the first port module and the intranet access system. This includes: the OLT sequentially sending the network access request to the first server associated with the URL of the network to be accessed through the main port and the intranet access system; if no first response data packet is received within a preset time period, the OLT sequentially sends the network access request to the first server associated with the URL of the network to be accessed through the backup port and the intranet access system again.

[0009] In this way, when the primary port fails, the OLT can still send network access requests to the first server associated with the URL of the network to be accessed through the backup port, ensuring high reliability.

[0010] In one optional implementation, the OLT includes a second port module connected to a first optical splitter, the first optical splitter being connected to multiple terminal devices. The OLT sends a first response data packet to the terminal devices, including: the OLT sending the first response data packet to the first optical splitter based on the second port module, so that the first optical splitter sends the first response data packet to the terminal device that issued the network access request among the multiple terminal devices.

[0011] This eliminates the need to configure multiple ports on the OLT device to send the first response data packet to the terminal device that issued the network access request among multiple terminal devices, saving costs.

[0012] In one optional implementation, the OLT further includes a first detection interface. The OLT sequentially sends a network access request to a first server associated with the URL of the network to be accessed through a first port module and an intranet access system. This includes: the OLT sending a network access request to the intranet access system according to a pre-configured URL of the intranet access system, so that the intranet access system sends a network access request to the first server. The URL of the intranet access system is configured to the OLT by the first management platform when the first detection interface detects that the bandwidth utilization of the intranet access system is less than a set threshold.

[0013] In this way, since the bandwidth utilization of the intranet access system is less than the set threshold, the reliability of the first server associated with the URL of the network to be accessed by the OLT is higher.

[0014] In an optional implementation, the OLT further includes a third port module for accessing the external network. After the OLT receives a network access request from the terminal device, the method provided in this application further includes: when the URL of the network to be accessed is an external network URL, the OLT sequentially sends an access request to a second server associated with the external network URL through the third port module and the external network access system; the OLT sequentially receives a second response data packet from the second server through the external network access system and the third port module; and the OLT sends the second response data packet to the terminal device.

[0015] Understandably, this also gives the OLT the ability to access the external network.

[0016] In one optional implementation, the OLT further includes a second detection interface. The OLT sequentially sends an access request to a second server associated with an external network address via a third port module and an external network access system. This includes: the OLT sending a network access request to the external network access system based on a pre-configured external network access system address, causing the external network access system to send a network access request to the second server. The address of the internal network access system is configured to the OLT by the second management platform based on the second detection interface when it detects that the bandwidth utilization of the external network access system is less than a set threshold. The OLT then sends a second response data packet to the terminal device via a gateway. This includes: the OLT sending a second response data packet to the gateway based on a pre-configured gateway address, causing the gateway to send a second response data packet to the terminal device. The gateway address is configured to the OLT by the second management platform based on the second detection interface when it detects that the bandwidth utilization of the external network access system is less than a set threshold.

[0017] Because the bandwidth utilization of the external network access system is less than the set threshold, the reliability of the first server associated with the URL of the network to be accessed by the OLT is higher.

[0018] Secondly, this application also provides a network access system, including a terminal device, an optical line terminal (OLT), an intranet access system, and a first server. The OLT includes a first port module for accessing the intranet, wherein the OLT is used to receive a network access request sent from the terminal device, wherein the network access request carries the URL of the network to be accessed; when the URL of the network to be accessed is an intranet URL, the OLT is also used to send the network access request to the first server associated with the URL of the network to be accessed sequentially through the first port module and the intranet access system; the OLT is also used to receive a first response data packet fed back by the first server based on the network access request sequentially through the intranet access system and the first port module; the OLT is also used to send the first response data packet to the terminal device.

[0019] Thirdly, this application provides an optical line terminal, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it causes the optical line terminal to perform the network access method provided in the first aspect of this application.

[0020] Fourthly, this application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, causes the computer to perform the network access method as provided in the first aspect of this application.

[0021] Fifthly, this application also provides a network access device, which includes an information receiving unit, a processing unit, and an information sending unit, wherein...

[0022] The information sending unit is used to receive network access requests sent from terminal devices, wherein the network access request carries the URL of the network to be accessed.

[0023] The processing unit is used to determine whether the URL of the network to be accessed is an internal network URL.

[0024] The information sending unit is used to send a network access request to the first server associated with the network address to be accessed through the first port module and the intranet access system in sequence when the address of the network to be accessed is an intranet address.

[0025] The network access method, system, and optical line terminal (OLT) provided in this application enable the OLT to access the external network. Furthermore, when the URL of the network to be accessed in the network access request is an internal network URL, the OLT can sequentially send a network access request to a first server associated with the URL of the network to be accessed through a first port module and an internal network access system; the OLT then sequentially receives a first response data packet from the first server based on the network access request through the internal network access system and the first port module; finally, the OLT sends the first response data packet to the terminal device. Therefore, the OLT also has the function of accessing the internal network. This eliminates the need for additional optical transport network (OTN) equipment, saving equipment cost and space. Moreover, the OLT's internal network access function and external network access function do not interfere with each other. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments made by those skilled in the art under the guidance of these embodiments are within the scope of protection of this application.

[0035] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] First, let me explain the terms used in this application:

[0037] OLT: Terminal equipment used to connect fiber optic trunk lines.

[0038] OTN: refers to transmission network equipment that enables the transmission, multiplexing, routing, and monitoring of service signals within the optical domain, while ensuring their performance indicators and survivability.

[0039] To meet the network needs of businesses in enterprise parks, network operators need to install optical line terminal (OLT) devices in the computer room for accessing the external network and optical transport network (OTN) devices for accessing the internal network.

[0040] Because it requires setting up both an OLT device and an OTN device in the computer room, the cost is high, the space occupied is large, and the power consumption is also high.

[0041] Based on the aforementioned technical problems, the inventive concept of this application is to configure a first port module in the OTN, enabling both the OTN and the OLT to access the intranet through this module. Thus, the OTN possesses both the ability to access the external network and the ability to access the intranet. This eliminates the need for additional optical transport network (OTN) equipment, saving on equipment costs and space requirements.

[0042] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] This application provides a network access method applied to an optical line terminal (OLT). The OLT includes a first port module 102 for accessing the intranet, which is, but is not limited to, a point-to-multipoint (P2MP) card. The P2MP card may include a P2MP line board and a P2MP tributary board for communication connection, both of which are inserted into the OLT's card slots. The transmission rate of the P2MP line board can be, but is not limited to, 10GE.

[0044] like Figure 1As shown, OLT101 is located in a network access system. This system also includes a first server 111, an intranet access system 105, and a first gateway 109. The first server 111, intranet access system 105, and first gateway 109 are sequentially connected. The first server 111 is an intranet server, such as a server for employee management applications or business management applications within an enterprise; this is not limited to any specific application. Additionally, the network access system includes a second server 110 and an extranet access system 106. The second server 110 is a server for extranet applications, such as a server for instant messaging applications or live streaming applications.

[0045] Figure 2 A flowchart illustrating a network access method provided in an embodiment of this application. Figure 2 As shown, the method provided in this application embodiment includes:

[0046] S201: OLT101 receives a network access request sent from a terminal device, wherein the network access request carries the URL of the network to be accessed.

[0047] The terminal device can be, but is not limited to, a user's office computer. For example, when a user opens an internal enterprise application, the terminal device can send a network access request to the OLT101 via the first gateway 109. The OLT101 then receives the network access request from the terminal device, which can carry the internal network URL.

[0048] S202: When the URL of the network to be accessed is an intranet URL, OLT101 sends a network access request to the first server 111 associated with the URL of the network to be accessed through the first port module 102 and the intranet access system 105 in sequence.

[0049] For example, the first port module 102 can be a P2MP line board, and the first port module 102 can include a main port 103 and a spare port 104. Figure 3 As shown, the specific implementation of S102 may include:

[0050] S301: OLT101 sends a network access request to the first server 111 associated with the URL of the network to be accessed through the main port 103 and the intranet access system 105 in sequence.

[0051] S302: OLT101 determines whether the first response data packet has been received within a preset time period. If not, S303 is executed; if yes, S304 is executed.

[0052] S303: OLT101 sequentially sends a network access request to the first server 111 associated with the URL of the network to be accessed through the backup port 104 and the intranet access system 105.

[0053] S304: OLT101 sequentially sends network access requests through main port 103 to the first server 111 associated with the URL of the network to be accessed.

[0054] For example, when the intranet address is the address of the server for the enterprise's internal employee management application, the OLT101 sequentially sends a network access request to the server for the enterprise's internal employee management application through the first port module 102 and the intranet access system 105. When the intranet address is the address of the server for the enterprise's internal business management application, the OLT101 sequentially sends a network access request to the server for the enterprise's internal business management application through the first port module 102 and the intranet access system 105.

[0055] Additionally, in an alternative implementation, in Figure 2 Based on the corresponding embodiments, such as Figure 4 As shown, the above-mentioned S102 can be specifically implemented as follows: OLT101 sends a network access request to the intranet access system 105 according to the pre-configured URL of the intranet access system 105, so that the intranet access system 105 sends a network access request to the first server 111.

[0056] Specifically, the URL of the intranet access system 105 is configured to the OLT 101 when the first management platform detects that the bandwidth utilization of the intranet access system 105 is less than a set threshold based on the first detection interface. In this way, because the bandwidth utilization of the intranet access system 105 is less than the set threshold, the reliability of the first server 111 associated with the URL of the network to be accessed by the OLT 101 is higher.

[0057] S203: OLT101 sequentially receives the first response data packet from the first server 111 based on the network access request through the intranet access system 105 and the first port module 102.

[0058] For example, after receiving a network access request, the first server 111 of the enterprise's internal employee management application sends a first response data packet to the OLT 101 through the intranet access system 105 and the first port module 102 in sequence. As another example, after receiving a network access request, the first server 111 of the enterprise's internal business management application sends a first response data packet to the OLT 101 through the intranet access system 105 and the first port module 102 in sequence.

[0059] S204: OLT101 sends the first response data packet to the terminal device.

[0060] Specifically, the OLT101 can send a first response data packet to the terminal device through the first gateway 109.

[0061] Thus, based on the above S201-S204, it can be seen that when the main port 103 fails, the OLT101 can still send a network access request to the first server 111 associated with the URL of the network to be accessed through the backup port 104, which has high reliability.

[0062] In summary, the network access method, system, and optical line terminal (OLT101) provided in this application embodiment have the function of accessing the external network. Furthermore, when the URL of the network to be accessed in the network access request is a URL of the internal network, OLT101 can sequentially send a network access request to the first server 111 associated with the URL of the network to be accessed through the first port module 102 and the internal network access system 105; OLT101 sequentially receives the first response data packet from the first server 111 based on the network access request through the internal network access system 105 and the first port module 102; OLT101 then sends the first response data packet to the terminal device. Therefore, OLT101 also has the function of accessing the internal network. This eliminates the need for additional optical transport network (OTN) equipment, saving equipment cost and space. Moreover, the OLT101's function of accessing the internal network and its function of accessing the external network do not interfere with each other.

[0063] In one alternative implementation, in Figure 2 Based on the corresponding embodiment, the OLT101 includes a second port module 112 (such as the P2MP tributary board described above). The second port module 112 is connected to a first optical splitter 107, and the first optical splitter 107 is connected to multiple terminal devices. The OLT101 sends a first response data packet to the first optical splitter 107 via the second port module 112, so that the first optical splitter 107 sends the first response data packet to the terminal device that issued the network access request among the multiple terminal devices via the first gateway 109. The first optical splitter 107 can be, but is not limited to, a 1:8 or 1:16 splitter. In this way, it is not necessary to configure multiple ports on the OLT101 device to send the first response data packet to the terminal device that issued the network access request among the multiple terminal devices, saving costs.

[0064] In one alternative implementation, such as Figure 1 As shown, the OLT101 also includes a third port module 113 for accessing the external network. Figure 2 Based on the corresponding embodiment, after S201, as follows: Figure 5 As shown, the method provided in this application embodiment further includes:

[0065] S501: When the URL of the network to be accessed is an external URL, OLT101 sends an access request to the second server 110 associated with the external URL through the third port module 113 and the external access system 106 in sequence.

[0066] S502: OLT101 receives the second response data packet from the second server 110 through the external network access system 106 and the third port module 113 in sequence.

[0067] For example, the external network access system 106 includes a switch, a broadband access server, and a core router that are connected in sequence.

[0068] S503: OLT101 sends a second response data packet to the terminal device.

[0069] Understandably, this also gives the OLT101 the ability to access the external network.

[0070] In addition, as before Figure 1 As shown, the OLT101 includes a fourth port module connected to a second optical splitter 108, which in turn is connected to multiple terminal devices. The OLT101 sends a second response data packet to the second optical splitter 108 via the fourth port module, enabling the second optical splitter 108 to send a second response data packet to the terminal device that issued the network access request among the multiple terminal devices via the first gateway 109. The second optical splitter 108 can be, but is not limited to, a 1:8 or 1:16 splitter. This eliminates the need to configure multiple ports on the OLT101 device to send the second response data packet to the terminal device that issued the network access request among the multiple terminal devices, thus saving costs.

[0071] The OLT101 also includes a second detection interface, such as Figure 6 As shown, S501 can be specifically implemented as follows: OLT101 sends a network access request to the external network access system 106 according to the pre-configured URL of the external network access system 106, so that the external network access system 106 sends a network access request to the second server 110.

[0072] The URL of the intranet access system 105 is configured to OLT101 by the second management platform based on the second detection interface when it detects that the bandwidth utilization of the extranet access system 106 is less than the set threshold.

[0073] In this way, S503 can be specifically implemented as follows: OLT101 sends a second response data packet to the gateway according to the pre-configured gateway address, so that the gateway sends a second response data packet to the terminal device.

[0074] The gateway address is configured to OLT101 by the second management platform based on the second detection interface when it detects that the bandwidth utilization of the external network access system 106 is less than the set threshold.

[0075] Understandably, since the bandwidth utilization of the external network access system 106 is less than the set threshold, the reliability of the first server 111 associated with the URL of the network to be accessed by the OLT101 is higher.

[0076] Please refer to Figure 1 This application also provides a network access system, including a terminal device, an optical line terminal (OLT) 101, an intranet access system 105, and a first server 111. The OLT 101 includes a first port module 102 for accessing the intranet.

[0077] The OLT101 is used to receive network access requests sent from terminal devices, which carry the URL of the network to be accessed.

[0078] When the URL of the network to be accessed is an intranet URL, the OLT101 is also used to send a network access request to the first server 111 associated with the URL of the network to be accessed through the first port module 102 and the intranet access system 105 in sequence.

[0079] In one alternative implementation, the first port module 102 is a point-to-multipoint (P2MP) board.

[0080] OLT101 is also used to receive the first response data packet from the first server 111 based on the network access request by sequentially accessing the intranet access system 105 and the first port module 102.

[0081] The OLT101 is also used to send the first response data packet to the terminal device.

[0082] Understandably, point-to-multipoint (P2MP) cards can access the intranet, thus enabling the OLT101 to access the intranet.

[0083] In one optional implementation, the OLT101 is specifically used to send a network access request to the first server 111 associated with the URL of the network to be accessed via the main port 103 and the intranet access system 105 in sequence; if the first response data packet is not received within a preset time period, the network access request is resent to the first server 111 associated with the URL of the network to be accessed via the backup port 104 and the intranet access system 105 in sequence.

[0084] In one optional embodiment, the OLT101 includes a second port module 112, which is connected to a first optical splitter 107. The first optical splitter 107 is connected to multiple terminal devices. Specifically, the OLT101 is used to send a first response data packet to the first optical splitter 107 based on the second port module 112, so that the first optical splitter 107 sends the first response data packet to the terminal device that issued the network access request among the multiple terminal devices.

[0085] In an optional implementation, the OLT101 further includes a first detection interface, which is specifically used to send a network access request to the intranet access system 105 according to the pre-configured URL of the intranet access system 105, so that the intranet access system 105 sends a network access request to the first server 111. The URL of the intranet access system 105 is configured to the OLT101 by the first management platform when it detects that the bandwidth utilization of the intranet access system 105 is less than a set threshold based on the first detection interface.

[0086] In an optional implementation, the OLT101 further includes a third port module 113 for accessing the external network. When the URL of the network to be accessed is an external network URL, the OLT101 is also used to send an access request to the second server 110 associated with the external network URL sequentially through the third port module 113 and the external network access system 106; the OLT101 receives the second response data packet from the server sequentially through the external network access system 106 and the third port module 113; and the OLT101 sends the second response data packet to the terminal device.

[0087] In one optional implementation, OLT101 further includes a second detection interface, specifically used to send a network access request to the external network access system 106 according to the pre-configured URL of the external network access system 106, so that the external network access system 106 sends a network access request to the second server 110. The URL of the internal network access system 105 is configured to OLT101 based on the second detection interface when the second management platform detects that the bandwidth utilization of the external network access system 106 is less than a set threshold. OLT101 sends a second response data packet to the terminal device through the gateway, including: OLT101 sending a second response data packet to the gateway according to the pre-configured gateway address, so that the gateway sends a second response data packet to the terminal device. The gateway address is configured to OLT101 based on the second detection interface when the second management platform detects that the bandwidth utilization of the external network access system 106 is less than a set threshold.

[0088] Please see Figure 7This application also provides a network access device 700. It should be noted that the network access device 700 provided in this application has the same basic principle and technical effects as the above embodiments. For the sake of brevity, any parts not mentioned in this application can be referred to the corresponding content in the above embodiments. The device 700 provided in this application includes an information receiving unit 701, a processing unit 702, and an information sending unit 703, wherein...

[0089] The information sending unit 703 is used to receive a network access request sent from a terminal device, wherein the network access request carries the URL of the network to be accessed.

[0090] Processing unit 702 is used to determine whether the URL of the network to be accessed is an internal network URL.

[0091] The information sending unit 703 is used to send a network access request to the first server associated with the network address to be accessed through the first port module and the intranet access system in sequence when the address of the network to be accessed is an intranet address.

[0092] In one alternative implementation, the first port module is a point-to-multipoint (P2MP) board.

[0093] The information receiving unit 701 is used to receive the first response data packet fed back by the first server based on the network access request through the intranet access system and the first port module in sequence.

[0094] The information sending unit 703 is used to send a first response data packet to the terminal device.

[0095] In one optional implementation, the first port module includes a main port and a backup port. The information sending unit 703 is specifically configured to sequentially send a network access request to a first server associated with the URL of the network to be accessed via the main port and the intranet access system; if no first response data packet is received within a preset time period, the network access request is resent to the first server associated with the URL of the network to be accessed via the backup port and the intranet access system.

[0096] In one optional implementation, the information sending unit 703 is specifically used to send a first response data packet to the first optical splitter based on the second port module, so that the first optical splitter sends the first response data packet to the terminal device that issued the network access request among multiple terminal devices.
