Description

Technical Field

[0001] This invention relates to the field of transmission network technology, and in particular to a method and system for analyzing bandwidth requirements of home broadband services. Background Technology

[0002] Currently, home broadband services are gradually developing towards larger granularity and higher bandwidth, and their transmission methods can include optical fiber, Optical Transport Network (OTN), and Packet Transport Network (PTN). As the number of users supported by home broadband increases, the bandwidth demand for home broadband services is growing. However, the transmission networks supporting home broadband services cannot perceive this bandwidth demand, and therefore cannot determine the bandwidth that needs to be provided to home broadband services without affecting the user's experience.

[0003] In existing technologies, because the Optical Line Terminal (OLT) and the transmission network do not communicate, the uplink bandwidth of the OLT can only be perceived through the traffic utilization of its uplink ports. Furthermore, when the OLT's uplink bandwidth is insufficient to meet the bandwidth requirements of broadband services, the traffic on the OLT's uplink ports will automatically decrease. Therefore, it is impossible to fully reflect the true bandwidth requirements of broadband services solely through the traffic utilization of the OLT's uplink ports. Moreover, since the traffic situation of the transmission network can only be viewed through transmission network traffic monitoring, traffic dropped due to insufficient uplink bandwidth is not included in the statistics. Thus, the traffic statistics of the OLT and the transmission network also cannot accurately reflect the bandwidth requirements of broadband services.

[0004] Therefore, this invention provides a method for analyzing bandwidth requirements of home broadband services. Summary of the Invention

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] Figure 1 This is a flowchart illustrating a method for analyzing bandwidth requirements for home broadband services provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes:

[0039] S1, collect the requested bandwidth information of the optical line terminal in the home broadband service and the first received bandwidth information of the service landing equipment connected to the optical line terminal in the transmission network; the requested bandwidth information is determined based on the bandwidth demand information received by the optical line terminal;

[0040] S2, based on the requested bandwidth information and the first received bandwidth information, analyze the bandwidth requirement information of the home broadband service.

[0041] Specifically, the broadband service bandwidth demand analysis method provided in this embodiment of the invention is executed by a broadband service bandwidth demand analysis system. This system can be configured in a server, which can be a local server or a cloud server. The local server can be a computer, tablet computer, etc., and this embodiment of the invention does not make specific limitations on this.

[0042] Here, "home broadband service" refers to the home broadband service, and the bandwidth requirement for home broadband service is the bandwidth required by the home broadband service without affecting the user's perception. In this embodiment of the invention, the bandwidth mentioned refers to the information traffic within a unit of time period, that is, the total number of IP packets within a unit of time period.

[0043] like Figure 2 The image shows an application scenario of the home broadband service bandwidth demand analysis method provided in this embodiment of the invention. This scenario is a cross-network service activation scenario. Figure 2 It includes two networks: one is the Optical Line Terminal (OLT) access network that enables home broadband services, and the other is the transmission network that enables home broadband services.

[0044] In the OLT access network, the OLT connects to the corresponding service landing device in the transmission network through its User Network Interface (UNI).

[0045] The transmission network includes multiple service landing devices, such as A2 and B2, as well as multiple core network devices, such as C2 and D2. Each service landing device interfaces with an OLT via a UNI. Figure 2 The example shown is B2.

[0046] The transmission network mainly carries home broadband services and connects to the Broadband Remote Access Server (BRAS) through service landing equipment, thereby enabling the core network equipment and BRAS to schedule to the OLT.

[0047] In the service delivery equipment, the service ports of the OLT are connected to the BRAS via the network to network interface (NNI) pigtail, thereby enabling the OLT to access the BRAS and realize service transmission from the OLT to the BRAS.

[0048] In existing technology, the OLT's UNI terminates all OLT service information and transmits it to the service landing device according to the first frame structure. Similarly, the service landing device's UNI also terminates all service information and transmits it to the transmission network according to the second frame structure. Since the first and second frame structures are not necessarily the same, this results in information not being interoperable between the OLT and the transmission network.

[0049] The development of home broadband services has placed greater demands on the uplink transmission bandwidth of OLTs. However, this can only be assessed through the traffic utilization of the OLT's uplink ports (UNIs). Furthermore, when the transmission capacity cannot meet the OLT's needs, the OLT's traffic automatically decreases, thus failing to fully reflect the true demand. The traffic situation of the transmission network can only be viewed through transmission network traffic monitoring, but packets dropped from the OLT due to insufficient transmission bandwidth are not included in the statistics. Therefore, the traffic statistics of the OLT and transmission network cannot accurately reflect the bandwidth requirements of home broadband development.

[0050] Therefore, the home broadband service bandwidth demand analysis system in this embodiment of the invention achieves automatic and real-time monitoring and analysis of home broadband service bandwidth demand by executing the following method process, so as to solve the problems existing in the prior art.

[0051] First, step S1 is executed to collect the requested bandwidth information of the OLT in the home broadband service and the first received bandwidth information of the service landing equipment connected to the OLT in the transmission network. The requested bandwidth information can be determined by the bandwidth demand information received by the OLT. The OLT can connect to several Optical Network Units (ONUs), and the OLT can receive the bandwidth demand information sent by each ONU. This bandwidth demand information refers to the bandwidth required by each ONU and can be transmitted in the form of IP packets. Therefore, the requested bandwidth information can be determined based on the bandwidth demand information received by the OLT, and this requested bandwidth information can be the sum of the bandwidth demand information sent by all ONUs.

[0052] Since broadband is the amount of information transmitted per unit time period, and traffic is the amount of information transmitted within a certain time period, the requested bandwidth information can be determined by the traffic acquisition device located at the UNI of the OLT, which collects the traffic information within a unit time period.

[0053] The first received bandwidth information refers to the bandwidth information received by the service landing device connected to the OLT in the transmission network. This first received bandwidth information can be determined by the traffic information collected within a unit time period by the traffic acquisition device set at the UNI of the service landing device connected to the OLT. This first received bandwidth information can also be transmitted in the form of IP packets.

[0054] Then, step S2 is executed, combining the requested bandwidth information and the first received bandwidth information to analyze the bandwidth requirements of the home broadband service. This analysis process determines whether the capacity of the OLT and the UNI on the connected service landing device can meet the bandwidth requirements of the home broadband service. Here, the requested bandwidth information can be compared with the first received bandwidth information, and the judgment can be made based on the comparison result.

[0055] For example, if the requested bandwidth information equals the first received bandwidth information, then the capacity of the OLT's UNI and the connected service landing device's UNI can be considered sufficient to meet the bandwidth requirements of the home broadband service. Otherwise, if the requested bandwidth information is greater than the first received bandwidth information, then the capacity of the OLT's UNI and the connected service landing device's UNI cannot meet the bandwidth requirements of the home broadband service, and the two UNIs need to be expanded, meaning that more bandwidth needs to be provided to the two UNIs to ensure a good user experience.

[0056] The home broadband service bandwidth demand analysis method provided in this embodiment of the invention first collects the requested bandwidth information of the optical line terminal (OLT) in the home broadband service and the first received bandwidth information of the service landing equipment connected to the OLT in the transmission network. The requested bandwidth information is determined based on the bandwidth demand information received by the OLT. Then, based on the requested bandwidth information and the first received bandwidth information, the bandwidth demand information of the home broadband service is analyzed. This method combines the requested bandwidth information of the OLT and the first received bandwidth information of the service landing equipment to analyze the bandwidth demand information of the home broadband service, realizing the linkage analysis of the requested bandwidth of the home broadband service and the bandwidth of the transmission network. It can accurately analyze whether the bandwidth demand information of the home broadband service can be met by the service landing equipment. In addition, subsequent processing can be performed based on the analysis results, which can provide a theoretical basis for subsequent processing.

[0057] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein the analysis of the bandwidth demand information of the home broadband service based on the requested bandwidth information and the first received bandwidth information includes:

[0058] If the requested bandwidth information is equal to the first received bandwidth information, then the second received bandwidth information of the home broadband service on the core device that is connected to the broadband access server in the transmission network is collected;

[0059] Based on the requested bandwidth information and the second received bandwidth information, the bandwidth requirement information of the home broadband service is analyzed.

[0060] Specifically, in this embodiment of the invention, when analyzing the bandwidth requirement information of home broadband services, if the requested bandwidth information equals the first received bandwidth information, it indicates that the capacity of the OLT's UNI and the UNI of the connected service landing device can meet the bandwidth requirements of the home broadband service. Subsequently, it can be further determined whether other devices involved in the home broadband service meet the bandwidth requirements of the home broadband service. In this embodiment of the invention, the second received bandwidth information of the home broadband service on the core device in the transmission network that interfaces with the broadband access server can be collected.

[0061] The second received broadband information refers to the bandwidth information related to home broadband services received by the core equipment in the transmission network that interfaces with the broadband access server. This second received broadband information can be determined by the traffic information collected within a unit time period by the traffic acquisition device at the NNI of the core equipment that interfaces with the broadband access server. This second received bandwidth information can also be transmitted in the form of IP packets.

[0062] Subsequently, the bandwidth requirements of the home broadband service can be analyzed by combining the requested bandwidth information and the second received bandwidth information. This analysis process involves determining whether the requested bandwidth information sent by the OLT is consistent with the bandwidth of the core device, that is, whether the bandwidth of the core device can meet the bandwidth requirements of the home broadband service. Here, the requested bandwidth information can be compared with the second received bandwidth information, and the judgment can be made based on the comparison result.

[0063] For example, if the requested bandwidth information equals the second received bandwidth information, it can be assumed that the requested bandwidth information sent by the OLT matches the bandwidth of the core device, meaning the core device's bandwidth can meet the bandwidth requirements of the home broadband service. Otherwise, if the requested bandwidth information is greater than the second received bandwidth information, it can be assumed that the requested bandwidth information sent by the OLT does not match the bandwidth of the core device, meaning the core device's bandwidth cannot meet the bandwidth requirements of the home broadband service. Therefore, it is necessary to expand the core device's capacity, i.e., to provide it with greater bandwidth to the home broadband service, thereby ensuring a good user experience.

[0064] In this embodiment of the invention, the bandwidth demand information of home broadband services is analyzed by combining the requested bandwidth information of the optical line terminal and the second received bandwidth information. This analysis can accurately determine whether the bandwidth demand information of home broadband services can be met by the core equipment in the transmission network. Furthermore, subsequent processing can be performed based on the analysis results, which provide a theoretical basis for these subsequent processes.

[0065] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein the analysis of the bandwidth demand information of the home broadband service based on the requested bandwidth information and the second received bandwidth information includes:

[0066] If the requested bandwidth information is equal to the second received bandwidth information, then the third received bandwidth information of the broadband access server in the transmission network for the core device being connected is collected;

[0067] Based on the requested bandwidth information and the third received bandwidth information, the bandwidth requirement information of the home broadband service is analyzed.

[0068] Specifically, in this embodiment of the invention, when analyzing the bandwidth requirement information of the home broadband service, if the requested bandwidth information equals the second received bandwidth information, it indicates that the requested bandwidth information sent by the OLT matches the bandwidth of the core device, and the bandwidth of the core device can meet the bandwidth requirements of the home broadband service. Subsequently, it can be further determined whether other devices involved in the home broadband service meet the bandwidth requirements of the home broadband service. In this embodiment of the invention, the third received bandwidth information of the broadband access server in the transmission network for the connected core device can be collected.

[0069] The third received broadband information refers to the bandwidth information related to home broadband services received by the broadband access server that interfaces with the core equipment in the transmission network. This third received broadband information can be determined by the traffic data collected within a unit time period by the traffic acquisition device located at the NNI of the broadband access server that interfaces with the core server. This third received bandwidth information can also be transmitted in the form of IP packets.

[0070] Subsequently, the bandwidth requirements of the home broadband service can be analyzed by combining the requested bandwidth information and the third-party received bandwidth information. This analysis process involves determining whether the requested bandwidth information sent by the OLT is consistent with the bandwidth of the broadband access server in the transmission network, that is, whether the bandwidth of the broadband access server can meet the bandwidth requirements of the home broadband service. Here, the requested bandwidth information can be compared with the third-party received bandwidth information, and the judgment can be made based on the comparison results.

[0071] For example, if the requested bandwidth information equals the third received bandwidth information, it can be assumed that the requested bandwidth information sent by the OLT matches the bandwidth of the broadband access server in the transmission network, meaning the bandwidth of the broadband access server can meet the bandwidth requirements of the home broadband service. Conversely, if the requested bandwidth information is greater than the third received bandwidth information, it can be assumed that the requested bandwidth information sent by the OLT does not match the bandwidth of the broadband access server in the transmission network, meaning the bandwidth of the broadband access server in the transmission network cannot meet the bandwidth requirements of the home broadband service. Therefore, it is necessary to expand the capacity of the broadband access server in the transmission network, providing it with greater bandwidth to support the home broadband service and ensure a good user experience.

[0072] In this embodiment of the invention, the bandwidth demand information of home broadband services is analyzed by combining the requested bandwidth information of the optical line terminal and the third received bandwidth information. This analysis can accurately determine whether the bandwidth demand information of home broadband services can be met by the broadband access server in the transmission network. Furthermore, subsequent processing can be performed based on the analysis results, which provide a theoretical basis for these subsequent processes.

[0073] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention includes the requested bandwidth information including the maximum value or summation result of the unit requested traffic information corresponding to each unit time period of the optical line terminal within a preset time period, and the first received bandwidth information including the maximum value or summation result of the unit received traffic information corresponding to each unit time period of the service landing device within the preset time period.

[0074] Specifically, the requested bandwidth information can be the maximum value or sum of the unit requested traffic information corresponding to each unit time period of the optical line terminal within a preset time period. Correspondingly, the first received bandwidth information can also be the maximum value or sum of the unit received traffic information corresponding to each unit time period of the service landing device within a preset time period. The second received bandwidth information can also be the maximum value or sum of the unit received traffic information corresponding to each unit time period of the core device within a preset time period. The third received bandwidth information can also be the maximum value or sum of the unit received traffic information corresponding to each unit time period of the broadband access server within a preset time period.

[0075] Understandably, both the preset time period and the unit time period can be set as needed. For example, the preset time period could be 24 hours, and the unit time period could be every hour; no specific limitations are imposed here. The maximum value is the largest of the 24 values, and the summation result is the sum of all 24 values.

[0076] Here, when comparing the requested bandwidth information with the first and second received bandwidth information, the maximum value can be used for comparison. Correspondingly, the maximum value is also used to determine the expansion bandwidth information when performing subsequent capacity expansion. When comparing the requested bandwidth information with the third received bandwidth information, the summation result can be used for comparison. Correspondingly, the maximum value is also used to determine the expansion bandwidth information when performing subsequent capacity expansion.

[0077] In this embodiment of the invention, the requested bandwidth information and the first received bandwidth information can both be characterized by different values, which can provide a reasonable data basis for determining the analysis results.

[0078] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein the analysis of the bandwidth demand information of the home broadband service based on the requested bandwidth information and the third received bandwidth information includes:

[0079] If the requested bandwidth information is greater than the third received bandwidth information, then the first expansion bandwidth information of the broadband access server is determined based on the requested bandwidth information, the first received bandwidth information, and the third received bandwidth information.

[0080] Based on the first expansion bandwidth information, the broadband access server is expanded.

[0081] Specifically, in this embodiment of the invention, when the requested bandwidth information is greater than the third received bandwidth information, the first expansion bandwidth information of the broadband access server can be determined by using the requested bandwidth information, the first received bandwidth information, and the third received bandwidth information. For example, the first expansion bandwidth information of the broadband access server can be calculated by summing the unit requested traffic information corresponding to each unit time period of the optical line terminal within a preset time period, summing the unit received traffic information corresponding to each unit time period of the service landing device within a preset time period, and summing the unit received traffic information corresponding to each unit time period of the broadband access server within a preset time period.

[0082] Here, the summation result of the unit request traffic information corresponding to each unit time period of the optical line terminal within the preset time period can be recorded as the terminal summation result. The summation result of the unit received traffic information corresponding to each unit time period of the service landing device within the preset time period can be recorded as the device summation result. The summation result of the unit received traffic information corresponding to each unit time period of the broadband access server within the preset time period can be recorded as the server summation result. Then, based on the terminal summation result, the device summation result, and the server summation result, the first expansion bandwidth information of the broadband access server is determined using the following formula:

[0083] First expansion bandwidth information = (terminal summation result + device summation result) / 2 / N - server summation result

[0084] Where N is the number of unit time periods within the preset time period. If the preset time period is 24 hours and the unit time period is 1 hour, then L is 24. The above formula averages the request bandwidth information obtained over 24 hours with the first receiving bandwidth information of the service landing device. No other related parameters are required, which simplifies the determination of the first expansion bandwidth information.

[0085] Subsequently, the broadband access server can be expanded based on the determined first expansion bandwidth information. That is, in addition to the current bandwidth of the broadband access server, the bandwidth of the broadband access server needs to be provided to match the first expansion bandwidth information in order to achieve expansion.

[0086] In this embodiment of the invention, by requesting bandwidth information, first receiving bandwidth information, and third receiving bandwidth information, the first expansion bandwidth information of the broadband access server can be determined, thereby accurately expanding the capacity of the broadband access server. This can avoid the problem of poor user experience due to insufficient expansion, and also avoid the problems of high expansion costs and resource waste due to excessive expansion.

[0087] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein the analysis of the bandwidth demand information of the home broadband service based on the requested bandwidth information and the first received bandwidth information includes:

[0088] If the requested bandwidth information is greater than the first received bandwidth information, then the second expansion bandwidth information of the service landing device is determined based on the difference between the requested bandwidth information and the first received bandwidth information.

[0089] Based on the second expanded bandwidth information, the capacity of the service delivery equipment is expanded.

[0090] Specifically, in this embodiment of the invention, when analyzing the bandwidth demand information of home broadband services, if the requested bandwidth information is greater than the first received bandwidth information, it indicates that the capacity of the OLT's UNI and the UNI of the connected service landing device cannot meet the bandwidth demand of the home broadband service, and the two UNIs need to be expanded. In this case, the difference between the requested bandwidth information and the first received bandwidth information can be calculated first.

[0091] When calculating this difference information, the requested bandwidth information can be the maximum value of the unit requested traffic information corresponding to each unit time period of the optical line terminal within the preset time period, and the first received bandwidth information can be the maximum value of the unit received traffic information corresponding to each unit time period of the service landing device within the preset time period. Then the difference information is the difference between the two maximum values ​​within the preset time period.

[0092] Then, based on the difference between the requested bandwidth information and the first received bandwidth information, the second expanded bandwidth information of the service landing device is determined. Here, this difference information can be directly used as the second expanded bandwidth information. Alternatively, parameters such as convergence ratio and concurrency rate can be introduced based on the difference information to jointly determine the second expanded bandwidth information; no specific limitation is made here.

[0093] Finally, based on the second expansion bandwidth information, the service delivery equipment is expanded. That is, in addition to the current bandwidth of the service delivery equipment, bandwidth matching the second expansion bandwidth information needs to be provided to achieve the expansion.

[0094] In this embodiment of the invention, the second expansion bandwidth information of the service landing device can be determined by the difference between the requested bandwidth information and the first received bandwidth information, thereby accurately realizing the expansion of the service landing device. This can avoid the problem of poor user experience due to insufficient expansion, and also avoid the problems of high expansion cost and resource waste due to excessive expansion.

[0095] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein determining the second expansion bandwidth information of the service landing device based on the difference information between the requested bandwidth information and the first received bandwidth information includes:

[0096] Determine the convergence ratio of the transmission network and the concurrency rate of the broadband service;

[0097] Based on the difference information, the convergence ratio, and the concurrency rate, the second expansion bandwidth information is determined.

[0098] Specifically, in this embodiment of the invention, when determining the second expansion bandwidth information, the convergence ratio of the transmission network and the concurrency rate of the broadband service can be determined first. Both the convergence ratio and the concurrency rate can be set as needed, and are not specifically limited here. For example, the convergence ratio can be set to 4:1, which is the ratio of required bandwidth to provided bandwidth. The concurrency rate can be set to 37%.

[0099] The convergence ratio is a process where N corresponds to M, and it is called convergence when N > M. Given the principles of queuing theory, when N customers arrive for service according to their probabilities, if a certain service quality (convergence condition) is agreed upon, only M (M < N) attendants are needed. It is equivalent to having more inputs than outputs. Simply put: when the traffic volume is large, the convergence ratio must be small; when the traffic volume is small, the convergence ratio can be large.

[0100] For example, at the user level, in the long-term average, if only one out of four users wants to make a call simultaneously, the convergence ratio at the user level can reach 4:1. The benefit of convergence is that it can save shared equipment, but the drawback is that there are call losses during peak hours.

[0101] The traffic convergence of data packets refers to the situation where data packets cannot be forwarded at line speed without packet loss due to non-fault reasons such as architecture and equipment during the network forwarding process. During traffic convergence, some ports of network devices will be congested, and then some packets will be discarded. There are mainly two reasons for network traffic convergence: the switch does not support line-speed forwarding, and traffic convergence may occur inside the switch; the network architecture design is improper, and traffic convergence will also exist when forwarding packets regardless of whether the switch is line-speed or not. The convergence caused by the switch not being line-speed means that a certain switch only has the switching capacity of 8Gbps line-speed forwarding. At a certain moment, traffic is simultaneously forwarded from 12 input interfaces to 12 output interfaces of the switch. When the traffic of each interface reaches 1Gbps full rate, there will definitely be congestion inside the switch, and at this time, the convergence of forwarding is formed. The actual traffic received by the switch per second is 12Gbps, but the packets forwarded out are only 8Gbps, and the convergence ratio is:

[0102] Input bandwidth (12Gbps) ÷ Output bandwidth (8Gbps) = 3:2

[0103] The convergence caused by improper network design means that if 4 servers are respectively connected to the access switch through gigabit links, and the access switch is connected to the core switch through 1 gigabit link. That is, the downstream bandwidth of the access switch is 4Gbps, and the upstream bandwidth of the access switch is 1Gbps, which is an asymmetric link, and the downstream-to-upstream link convergence ratio is:

[0104] Downstream bandwidth (4Gbps) ÷ Upstream bandwidth (1Gbps) = 4:1

[0105] A smaller convergence ratio can ensure a higher network transmission efficiency.

[0106] The concurrency rate of broadband services refers to the ratio of the number of users online simultaneously to the total number of users in the system. The number of system users refers to the system's rated user count. For example, an OA system might have a total of 5000 users; this number is the system's user count. The number of users online simultaneously refers to the maximum number of users online at the same time within a certain time frame.

[0107] Simultaneous online users = Requests per second (RPS) (throughput) + Concurrent connections + Average user think time.

[0108] The number of concurrent connections can be either the average number of concurrent connections or the peak number of concurrent connections; no specific limitation is made here.

[0109] The average number of concurrent users, or average number of concurrent connections, can be calculated using the following formula:

[0110] C = nL / T

[0111] Where C is the average number of concurrent users, n is the average number of users accessing the system per day (login session), L is the average time from login to logout per day (average time of login session), and T is the duration of the observation period (how long users use the system within a day).

[0112] The peak number of concurrent users, i.e., the peak number of concurrent connections, can be calculated using the following formula:

[0113]

[0114] in, The peak number of concurrent users is denoted as , and C is the average number of concurrent users. This formula follows the Poisson distribution theory.

[0115] Then, by combining the difference between the requested bandwidth information and the first received bandwidth information with the determined convergence ratio and concurrency rate, the second expansion bandwidth information is determined. The requested bandwidth information is the maximum value of the unit requested traffic information corresponding to each unit time period of the optical line terminal within a preset time period, denoted as the terminal maximum value. The maximum value of the unit received traffic information corresponding to each unit time period of the service landing device within the preset time period is denoted as the device maximum value. The difference information is then the difference between the terminal maximum value and the device maximum value. Furthermore, the second expansion bandwidth information can be obtained using the following formula:

[0116] Second expansion bandwidth information = (maximum terminal value - maximum device value) * convergence ratio * concurrency rate

[0117] In this embodiment of the invention, the second expansion bandwidth information is determined by introducing the convergence ratio of the transmission network and the concurrency rate of the broadband service. This allows for a comprehensive consideration of the actual situation of the transmission network and the broadband service, making the second expansion bandwidth information more accurate and facilitating the subsequent accurate expansion of the service deployment equipment.

[0118] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein the analysis of the bandwidth demand information of the home broadband service based on the requested bandwidth information and the second received bandwidth information includes:

[0119] If the requested bandwidth information is greater than the second received bandwidth information, then the third expansion bandwidth information of the service landing device is determined based on the difference between the requested bandwidth information and the second received bandwidth information.

[0120] Based on the third expansion bandwidth information, the core equipment in the transmission network that interfaces with the broadband access server is expanded.

[0121] Specifically, in this embodiment of the invention, when the requested bandwidth information is greater than the second received bandwidth information, it indicates that the requested bandwidth information sent by the OLT does not match the bandwidth of the core device, meaning that the bandwidth of the core device cannot meet the bandwidth requirements of the home broadband service, and therefore the core device needs to be expanded. In this case, the third expansion bandwidth information of the service landing device needs to be determined by using the difference between the requested bandwidth information and the second received bandwidth information.

[0122] When calculating this difference information, the requested bandwidth information can be the maximum value of the unit requested traffic information corresponding to each unit time period of the optical line terminal within the preset time period, and the second received bandwidth information can be the maximum value of the unit received traffic information corresponding to each unit time period of the core device within the preset time period. Then the difference information is the difference between the two maximum values ​​within the preset time period.

[0123] Then, based on the difference between the requested bandwidth information and the second received bandwidth information, the third expanded bandwidth information of the service landing device is determined. Here, this difference information can be directly used as the third expanded bandwidth information. Alternatively, parameters such as convergence ratio and concurrency rate can be introduced based on the difference information to jointly determine the third expanded bandwidth information; no specific limitation is made here.

[0124] Finally, based on the third expansion bandwidth information, the core equipment in the transmission network that interfaces with the broadband access server is expanded. That is, in addition to the current bandwidth of the core equipment, bandwidth matching the third expansion bandwidth information needs to be provided to the core equipment to achieve expansion.

[0125] In this embodiment of the invention, the third expansion bandwidth information of the service landing device can be determined by the difference between the requested bandwidth information and the second received bandwidth information, thereby accurately realizing the expansion of the core device. This can avoid the problem of poor user experience due to insufficient expansion, and also avoid the problems of high expansion cost and resource waste due to excessive expansion.

[0126] Based on the above embodiments, the home broadband service bandwidth demand analysis method provided in this embodiment of the invention, wherein determining the third expansion bandwidth information of the service landing device based on the difference information between the requested bandwidth information and the second received bandwidth information includes:

[0127] Determine the convergence ratio of the transmission network and the concurrency rate of the broadband service;

[0128] The third expansion bandwidth information is determined based on the difference between the requested bandwidth information and the second received bandwidth information, the convergence ratio, and the concurrency rate.

[0129] Specifically, the methods for determining the convergence ratio and concurrency rate are consistent with those in the above embodiments, and are not specifically limited here.

[0130] The maximum value of the unit request traffic information corresponding to each unit time period within the preset time period of the optical line terminal is recorded as the terminal maximum value, and the maximum value of the unit receive traffic information corresponding to each unit time period within the preset time period of the core device is recorded as the core device maximum value. Then, the third expansion bandwidth information can be calculated by the following formula.

[0131] Third expansion bandwidth information = (maximum terminal value - maximum core device value) * convergence ratio * concurrency rate

[0132] In summary, this invention provides a method for automatically monitoring home broadband bandwidth demand. Through end-to-end automatic monitoring and analysis of the OLT and transmission network, it achieves real-time tracking and monitoring of home broadband bandwidth demand, promptly proposing expansion requests to the transmission network to meet the speed increase needs of home broadband users. This method overcomes the shortcoming of the lack of linkage between home broadband bandwidth demand monitoring and transmission bandwidth provision monitoring. The linked monitoring mechanism enables automatic analysis of home broadband bandwidth demand and transmission bandwidth provision capacity, thereby providing expansion algorithms for transmission bearers in the home broadband network. This mechanism achieves automatic connection between the demand and provision aspects of home broadband and the transmission network, thus providing an automated means to promptly meet the bandwidth needs of home broadband users.
