Description

Technical Field

[0001] This disclosure relates to the field of communication technology, specifically to a method for configuring uplink bandwidth, a system for configuring uplink bandwidth, an electronic device, and a computer-readable storage medium. Background Technology

[0002] As people's demand for internet speed increases, broadband networks are rapidly developing with fiber-to-the-x (FTTx) access. Driven by the need for faster speeds and lower costs, mainstream downlink bandwidth is evolving from 100M to 500M and 1G. As FTTx network traffic grows rapidly, FTTx network equipment needs continuous expansion and upgrades. It also requires adjustments to the optical distribution network (ODN) between the central office equipment (optical line terminal, OLT) and the user-side optical network unit (ONU).

[0003] The FTTx network, carried by Internet Protocol addresses (IP), is a statistically multiplexed network. How to optimize and upgrade the FTTx network in a timely manner according to the increase in network traffic to avoid congestion has become an urgent problem to be solved.

[0004] In the early stages of global broadband network development, ADSL (Asymmetric Digital Subscriber Line) technology was used to build broadband access networks. ADSL is a technology with asymmetrical upstream and downstream speeds; its maximum upstream speed is only 640kb / s, far lower than its downstream speed. In recent years, with the development and popularization of the internet, interactive internet services such as P2P downloads, games, and videos have become increasingly abundant, leading to a growing demand for higher broadband upstream speeds. Therefore, broadband upstream speed has become a focal point of public and societal attention. However, current fixed broadband, especially home broadband, primarily focuses on downstream bandwidth, with less emphasis on upstream bandwidth. Summary of the Invention

[0005] To at least address the technical problems of how to configure uplink bandwidth in the prior art, this disclosure provides a method for configuring uplink bandwidth, a system for configuring uplink bandwidth, an electronic device, and a computer-readable storage medium, which can guarantee users' uplink speed requirements for broadband networks.

[0006] Firstly, this disclosure provides a method for configuring uplink bandwidth, the method

[0007] include:

[0008] The uplink port bandwidth for each broadband service package tier is determined based on the contracted bandwidth.

[0009] Determine the splitting ratio 1:N of the ODN connected to the PON (Passive Optical Network) port of the target optical access network's OLT;

[0010] Determine the target penetration rate for each tier of broadband service packages with different contracted bandwidths;

[0011] Calculate the target number of users for each broadband service package tier;

[0012] Calculate the uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y;

[0013] Calculate the concurrent uplink bandwidth of the PON port of the OLT under the target number of users of each broadband service package.

[0014] Device selection and network configuration are based on the concurrent uplink bandwidth of the PON port.

[0015] Furthermore, the method of determining the upper limit of each broadband service package based on the contracted bandwidth...

[0016] Line bandwidth includes:

[0017] When the contracted bandwidth is less than or equal to 500 Mbit / s, the uplink bandwidth and the contracted downlink access rate shall be configured in a minimum ratio of 1:5.

[0018] When the contracted bandwidth is greater than 500 Mbit / s, the minimum uplink bandwidth is 100 Mbit / s.

[0019] Furthermore, the target number of users for each broadband service package is obtained by calculating and rounding using the following formula (1):

[0020] U i =N*X i (1)

[0021] Among them U i The target number of users for broadband service package i, and U i X is an integer. i Let X1 + X2 + ... + X be the target penetration rate for broadband service package i, where i = the total number of broadband service packages, and X1 + X2 + ... + X i =1, U1+U2+....+U i =N.

[0022] Furthermore, the uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y is calculated using the following formula (2):

[0023] M i=m i *U i *Y (2)

[0024] Wherein, the peak-hour concurrency rate Y is the number of users simultaneously accessing the internet during a certain time period under the peak-hour OLT / the total number of subscribed users under that OLT, and M i For broadband service package i, the uplink bandwidth under busy-hour concurrency rate Y, m i The uplink port bandwidth of broadband service package i, determined based on the contracted bandwidth.

[0025] Furthermore, the step of selecting equipment and configuring the network based on the concurrent uplink bandwidth of the PON port includes:

[0026] For newly built OLT equipment, when selecting equipment, choose a device whose guaranteed bandwidth is greater than the concurrent uplink bandwidth of the PON port of the OLT. The guaranteed uplink bandwidth that the OLT can provide is determined by the PON's dynamic bandwidth allocation (DBA) algorithm and the OLT's technical standard.

[0027] For existing OLTs, if the concurrent uplink bandwidth of the OLT's PON port exceeds the guaranteed uplink bandwidth that the OLT can provide, then modify the network configuration.

[0028] The modification of network configuration includes one or more of the following methods:

[0029] Reduce the number of target users under the PON ports of one or more OLTs;

[0030] Upgrade the OLT equipment;

[0031] Adjust the target penetration rate of broadband service packages.

[0032] Secondly, this disclosure provides a system for configuring uplink bandwidth, the system comprising:

[0033] The module is configured to determine the uplink port bandwidth for each broadband service package tier based on the contracted bandwidth; and,

[0034] Determine the splitting ratio 1:N of the ODN connected to the PON port of the target optical access network's OLT;

[0039] The configuration module is set to select devices and configure the network based on the concurrent uplink bandwidth of the PON port.

[0040] Furthermore, the calculation module is specifically configured as follows:

[0041] The target number of broadband service packages for each tier is obtained by calculating and rounding using the following formula (1):

[0042] U i =N*X i (1)

[0043] Among them U i The target number of users for broadband service package i, and U i X is an integer. i Let X1 + X2 + ... + X be the target penetration rate for broadband service package i, where i = the total number of broadband service packages, and X1 + X2 + ... + X i =1, U1+U2+....+U i =N; and,

[0044] The uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y is calculated using the following formula (2):

[0045] M i =m i *U i *Y (2)

[0046] Wherein, the peak-hour concurrency rate Y is the number of users simultaneously accessing the internet during a certain time period under the peak-hour OLT / the total number of subscribed users under that OLT, and M i For broadband service package i, the uplink bandwidth under busy-hour concurrency rate Y, m i The uplink port bandwidth of broadband service package i, determined based on the contracted bandwidth.

[0047] Furthermore, the configuration module is specifically configured as follows:

[0048] For newly built OLT equipment, when selecting equipment, choose a device whose guaranteed bandwidth is greater than the concurrent uplink bandwidth of the PON port of the OLT. The guaranteed uplink bandwidth that the OLT can provide is determined by the dynamic bandwidth allocation (DBA) algorithm of PON and the technical standard of the OLT.

[0049] For existing OLTs, if the concurrent uplink bandwidth of the OLT's PON port exceeds the guaranteed uplink bandwidth that the OLT can provide, then modify the network configuration.

[0050] The modification of network configuration includes one or more of the following methods:

[0051] Reduce the number of target users under the PON ports of one or more OLTs;

[0052] Upgrade the OLT equipment;

[0053] Adjust the target penetration rate of broadband service packages.

[0054] Thirdly, this disclosure provides an electronic device including a memory and a processor, wherein the memory stores a computer program, and when the processor runs the computer program stored in the memory, the processor performs an uplink bandwidth configuration method as described in any of the first aspects.

[0065] In recent years, with the development and popularization of the Internet, interactive Internet services such as P2P downloads, games, and videos have become increasingly abundant, leading to a growing demand from users for broadband uplink speeds. Simultaneously, Broadband Optical Access Network (FTTx) technology has become the mainstream technology for broadband access networks, providing the technical possibility for significantly improving broadband access network uplink speeds. However, current broadband network access products often exhibit an asymmetry between uplink and downlink speeds, with the uplink speed being significantly lower than the downlink speed. To address these issues and meet user needs, telecommunications industry standards have standardized the uplink access speed configuration requirements for public users' fixed broadband access service contracts, thus improving home broadband uplink speeds. With the continued implementation of broadband network speed-up and price-reduction initiatives, broadband speeds have further increased significantly. Ensuring users' uplink bandwidth requirements has become a key issue for operators to consider.

Moreover, the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0067] Figure 1 This is a flowchart illustrating an uplink bandwidth configuration method provided in Embodiment 1 of this disclosure, as shown below. Figure 1 As shown, the method includes steps S101-S107;

[0068] Step S101: Determine the uplink port bandwidth for each broadband service package tier based on the contracted bandwidth;

[0069] Currently, there are various standards for broadband optical access, such as EPON (Ethernet Passive Optical Network), 10G-EPON (10G Ethernet Passive Optical Network), GPON (Gigabit Passive Optical Network), and 10G-GPON (10Gigabit Passive Optical Network). Each standard has different technical characteristics. The technical characteristics of various optical access network standards are shown in Table 1 below.

[0070] Table 1: Technical Characteristics of Various Optical Access Network Technology Standards

[0071]

[0072] It's worth noting that the ITU-T (International Telecommunication Union-Telecommunication Standardization) has developed two standards: the (asymmetric) 10 Gigabit Passive Optical Network (XG-PON) and the symmetric 10 Gigabit Passive Optical Network (XGS-PON). The industry typically refers to XG-PON and XGS-PON collectively as 10G-GPON. Broadband bandwidth is measured in megabits (M), and the corresponding broadband (line) rate is measured in megabits per second (Mbit / s); for example, 100M bandwidth corresponds to a broadband line rate of 100Mbit / s.

[0073] In the current network, the ONU uplink configuration for dynamic bandwidth allocation (DBA) on the user side is generally not configured for fixed bandwidth. For guaranteed bandwidth, the bandwidth is as follows: EPON: 960M / 32 = 30M, GPON: 1000M / 64 = 15M, asymmetric 10G-EPON: 960M / 64 = 15M, symmetric 10G-EPON: 7600M / 64 = 118M, XG-PON: 2000M / 64 = 31M, XGS-PON (10Gigabit Symmetric Passive Optical Network): 8300M / 64 = 129M. The maximum bandwidth is generally configured to be 500M or 1000M.

[0074] When allocating different uplink bandwidths to users with different downlink bandwidths (contracted bandwidths), it is necessary to ensure that the guaranteed bandwidth provided by the OLT is greater than the concurrent uplink bandwidth of the PON port of the OLT. Therefore, the concurrent uplink bandwidth of the PON port of the OLT under the set or existing configuration should be calculated first.

[0075] First, determine the uplink port bandwidth for each broadband service package tier based on the contracted bandwidth. Then, determine the user's uplink port bandwidth based on the user's contracted bandwidth (generally the downlink bandwidth).

[0076] Furthermore, determining the uplink bandwidth for each broadband service package tier based on the contracted bandwidth includes:

[0077] When the contracted bandwidth is less than or equal to 500 Mbit / s, the uplink bandwidth and the contracted downlink access rate shall be configured in a minimum ratio of 1:5.

[0078] When the contracted bandwidth is greater than 500 Mbit / s, the minimum uplink bandwidth is 100 Mbit / s.

[0079] For example, if the contracted bandwidth is 100 Mbit / s, the guaranteed uplink bandwidth for the user is 20 Mbit / s.

[0080] Step S102: Determine the splitting ratio 1:N of the ODN connected to the PON port of the target optical access network OLT;

[0081] Then, the splitting ratio of the ODN is determined according to the technical standard of the optical access network, which is 1:N. For the existing ODN, the splitting ratio of EPON / 10G-EPON equipment is usually 1:32; and the splitting ratio of GPON / 10G-GPON equipment is usually 1:64.

[0082] Step S103: Determine the target penetration rate for each tier of broadband service packages with different contracted bandwidths;

[0083] The target penetration rate for each broadband service package is the proportion of users who have signed up for that package. The target penetration rate can be changed by the operator's operating strategy.

[0084] Step S104: Calculate the target number of users for each broadband service package tier;

[0085] The target number of users can be determined based on the split ratio and the target penetration rate of each broadband service package.

[0086] Furthermore, the target number of users for each broadband service package is obtained by calculating and rounding using the following formula (1):

[0087] U i =N*X i (1)

[0088] Among them U i The target number of users for broadband service package i, and U i X is an integer. i Let X1 + X2 + ... + X be the target penetration rate for broadband service package i, where i = the total number of broadband service packages, and X1 + X2 + ... + X i =1, U1+U2+....+U i =N. i is a natural number greater than or equal to 1.

[0089] Calculate U i The result is usually rounded to the nearest integer, and the total number of target users for each broadband service package is N. N is a natural number greater than or equal to 1.

[0090] Step S105: Calculate the uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y;

[0091] The peak-hour concurrency rate Y is the number of users simultaneously accessing the internet during a certain period under the peak-hour OLT / the total number of subscribed users under that OLT. The value of the peak-hour concurrency rate Y is derived from the recent detection results of network traffic and user behavior.

[0092] Furthermore,

[0093] The uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y is calculated using the following formula (2):

[0094] M i =m i *U i *Y (2)

[0095] Wherein, the peak-hour concurrency rate Y is the number of users simultaneously accessing the internet during a certain time period under the peak-hour OLT / the total number of subscribed users under that OLT, and M i For broadband service package i, the uplink bandwidth under busy-hour concurrency rate Y, mi The uplink port bandwidth of broadband service package i, determined based on the contracted bandwidth.

[0096] Uplink bandwidth is mainly detected by monitoring the uplink traffic of the PON port of the OLT. By calculating the uplink bandwidth requirements under different busy-hour concurrency rates Y, the concurrent uplink bandwidth that the device can meet under busy-hour concurrency rates is determined, thereby enabling device or configuration adjustments.

[0097] Step S106: Calculate the concurrent uplink bandwidth of the PON port of the OLT under the target number of users of each broadband service package.

[0098] The concurrent uplink bandwidth of the OLT's PON port = M1 + M2 ... + M i The calculated concurrent uplink bandwidth is the requirement that equipment under the optical access network's technical standard must meet.

[0099] Step S107: Select equipment and configure the network based on the concurrent uplink bandwidth of the PON port.

[0100] Whether configuration adjustments are needed is determined by checking if the guaranteed bandwidth provided by the OLT is greater than the concurrent uplink bandwidth of its PON port. The guaranteed uplink bandwidth values ​​for each type of OLT are shown in Table 1. If the guaranteed bandwidth provided by the OLT is greater than the concurrent uplink bandwidth of its PON port, broadband service can be guaranteed, and no adjustments are required. If not, the user's uplink bandwidth requirements cannot be guaranteed, necessitating equipment replacement or network configuration adjustments.

[0101] Furthermore, the step of selecting equipment and configuring the network based on the concurrent uplink bandwidth of the PON port includes:

[0102] For newly built OLT equipment, when selecting equipment, choose a device whose guaranteed bandwidth is greater than the concurrent uplink bandwidth of the PON port of the OLT. The guaranteed uplink bandwidth that the OLT can provide is determined by the PON DBA algorithm and the technical standard of the OLT.

[0103] For existing OLTs, if the concurrent uplink bandwidth of the OLT's PON port exceeds the guaranteed uplink bandwidth that the OLT can provide, then modify the network configuration.

[0104] The modification of network configuration includes one or more of the following methods:

[0105] Reduce the number of target users under the PON ports of one or more OLTs;

[0106] Upgrade the OLT equipment;

[0107] Adjust the target penetration rate of broadband service packages.

[0108] Table 1 shows the guaranteed uplink bandwidth values ​​for each type of OLT. The concurrent uplink bandwidth of the OLT's PON port provides a reference for equipment selection. When existing OLTs cannot meet the requirements, the concurrent uplink bandwidth requirement of the OLT's PON port can be reduced by adjusting the target penetration rate of the broadband service package, decreasing the number of target users under one or more OLT PON ports, or upgrading the OLT equipment (e.g., upgrading EPON to 10G-EPON, or asymmetric 10G-EPON to symmetric 10G-EPON). This increases the guaranteed uplink bandwidth that the equipment can provide, thereby ensuring the uplink bandwidth requirements of each user.

[0109] This disclosure allows for the analysis of the concurrent uplink bandwidth of the OLT's PON port under the target number of users for various broadband service packages. This provides a basis for equipment selection and, when existing equipment cannot guarantee users' uplink bandwidth requirements, adjusts network configuration to meet user needs and ensure users' uplink speed requirements for broadband networks. Furthermore, during service adjustments, it can determine whether the adjustments can guarantee users' uplink bandwidth requirements, providing a reference for service adjustments. It also enables timely optimization and upgrading of the FTTx network based on increased network traffic to avoid congestion, providing a valuable reference for telecommunications operators' broadband network planning and construction.

[0110] Example 2:

[0111] Uplink rate configuration for EPON / 10G-EPON equipment at a split ratio of (1:32);

[0112] The concurrent uplink bandwidth of the OLT's PON port during different busy periods is calculated using the uplink bandwidth configuration method, based on the target number of users for each package. The calculation process includes:

[0113] The uplink port bandwidth (m) for each broadband service package tier is determined based on the contracted bandwidth. i ;

[0114] When the contracted bandwidth is less than or equal to 500 Mbit / s, the uplink bandwidth and the contracted downlink access rate shall be configured in a minimum ratio of 1:5.

[0115] When the contracted bandwidth is greater than 500 Mbit / s, the minimum uplink bandwidth is 100 Mbit / s.

[0116] Determine the splitting ratio of the ODN connected to the PON port of the target optical access network as 1:N; where N is a natural number greater than or equal to 1.

[0117] The splitting ratio of EPON / 10G-EPON equipment is typically 1:32;

[0118] The splitting ratio of GPON / 10G-GPON equipment is typically 1:64.

[0119] Determine the target penetration rate X for each tier of broadband service packages with different contracted bandwidths. i Where i = the total number of broadband service packages, and X1 + X2.... + X i =1. i is a natural number greater than or equal to 1.

[0120] Calculate the target number of users for each broadband service package tier;

[0121] Target user count U i =N*X i U i If the number is positive, it usually needs to be rounded to the nearest integer, and U1 + ... + U i =N.

[0122] The optional value of N can be N' - the number of spare optical fibers, where the ODN splitting ratio is 1:N', and the value of N' is derived from the ODN splitting ratio. N and N' are natural numbers greater than or equal to 1.

[0123] Calculate the uplink bandwidth M of each broadband service package under different busy-hour concurrency rates Y. i ;

[0124] M i =m i *U i *Y, Busy Hour Concurrency Rate Y: The number of users simultaneously accessing the internet during a certain time period under the OLT during busy hours / the total number of subscribed users under the OLT. Y is not greater than 1 and is also called the convergence ratio.

[0125] Calculate the concurrent uplink bandwidth of the OLT's PON port under the target number of users for each broadband service package tier: M1 + ... M i .

[0126] The calculation results for the short-term effects over the current period are shown in Tables 2 and 3 below:

[0127] Table 2: Short-term performance of EPON / 10G-EPON equipment in terms of target user numbers for each package and concurrent uplink bandwidth of OLT PON ports during different busy hours.

[0128]

[0129] Calculations show that the short-term effects over the current time period are as follows:

[0130] The actual allocatable uplink bandwidth of EPON / Asymmetric 10G-EPON is 960M. According to the current broadband user penetration rate model, it can guarantee 70% concurrent uplink bandwidth during busy periods (960M is the minimum requirement for the equipment, but there are fluctuations when users use it).

[0131] The symmetrical 10G-EPON has an actual allocatable uplink bandwidth of 7600M, which can meet the overall contracted access rate adjustment of 1:5.

[0132] In a symmetrical 10G-EPON network, the number of EPON ONUs directly affects the allocatable uplink bandwidth guarantee capability.

[0133] The calculation results for the subsequent long-term effects (mainly broadband upgrades, focusing on 500M and 1000M) are shown in Table 3 below:

[0134] Table 3: Long-term performance of EPON / 10G-EPON equipment based on target user numbers for each package and concurrent uplink bandwidth of OLT PON ports during different busy periods.

[0135]

[0136] Long-term effects:

[0137] The asymmetric 10G-EPON has an actual allocatable uplink bandwidth of 960M, and can guarantee 30% concurrent uplink bandwidth during peak hours for future gigabit user access.

[0138] The symmetrical 10G-EPON has an actual allocatable uplink bandwidth of 7600M, which can meet the overall contracted access rate adjustment of 1:5.

[0139] For GPON / 10G-GPON equipment, the rate configuration at a split ratio of 1:64;

[0140] The results obtained by calculating the uplink bandwidth configuration method described above are shown in Tables 4 and 5 below:

[0141] Table 4: Short-term performance of GPON / 10G-GPON equipment in terms of target user numbers for each package and concurrent uplink bandwidth of OLT PON ports during different busy hours.

[0142]

[0143] Short-term effects:

[0144] GPON's actual allocatable uplink bandwidth capacity is 1000M. According to the current broadband user penetration rate model, it can only guarantee 30% concurrent uplink bandwidth during peak hours.

[0145] XG-PON has an actual uplink bandwidth capacity of 2000M, and according to the current broadband user penetration rate model, it can guarantee 70% concurrent uplink bandwidth during peak hours.

[0146] XGS-PON has an actual allocatable uplink bandwidth capacity of 8300M, which can meet the overall contracted access rate adjustment of 1:5.

[0147] Table 5: Long-term performance of GPON / 10G-GPON equipment based on target user numbers for each package and concurrent uplink bandwidth of OLT PON ports during different busy periods.

[0148]

[0149] Long-term effects:

[0150] XG-PON has an actual allocatable uplink bandwidth capacity of 2000M, and can guarantee 30% concurrent uplink bandwidth during peak hours for future full gigabit user access.

[0151] XGS-PON has an actual allocatable uplink bandwidth capacity of 8300M, which can meet the overall contracted access rate adjustment of 1:5.

[0152] As can be seen from Table 2-5 above,

[0153] When asymmetric 10G-EPON, GPON, or XG-PON ports are used to access gigabit broadband services, if the peak utilization rate of the port's uplink bandwidth reaches 70%, it is necessary to consider splitting the port carrying gigabit services into PON ports, or to transfer the services to symmetric 10G-EPON or XGS-PON ports for carrying.

[0154] To further improve the precision of uplink traffic detection, future plans could consider deploying second-level traffic acquisition based on a telemetry network model.

[0155] The broadband access user number plan is shown in Table 6 below, based on the calculated contracted access rate ratio of 1:5.

[0170] Furthermore, the calculation module 12 is specifically configured as follows:

[0171] The target number of broadband service packages for each tier is obtained by calculating and rounding using the following formula (1):

[0172] U i =N*X i (1)

[0173] Among them U i The target number of users for broadband service package i, and U i X is an integer. i Let X1 + X2 + ... + X be the target penetration rate for broadband service package i, where i = the total number of broadband service packages, and X1 + X2 + ... + X i =1, U1+U2+....+U i =N; and,

[0174] The uplink bandwidth of each broadband service package under different busy-hour concurrency rates Y is calculated using the following formula (2):

[0175] M i =m i *U i *Y (2)

[0176] Wherein, the peak-hour concurrency rate Y is the number of users simultaneously accessing the internet during a certain time period under the peak-hour OLT / the total number of subscribed users under that OLT, and M i For broadband service package i, the uplink bandwidth under busy-hour concurrency rate Y, m i The uplink port bandwidth of broadband service package i, determined based on the contracted bandwidth.

[0177] Furthermore, the configuration module 13 is specifically configured as follows:

[0178] For newly built OLT equipment, when selecting equipment, choose a device whose guaranteed bandwidth is greater than the concurrent uplink bandwidth of the PON port of the OLT. The guaranteed uplink bandwidth that the OLT can provide is determined by the dynamic bandwidth allocation (DBA) algorithm of PON and the technical standard of the OLT.

[0179] For existing OLTs, if the concurrent uplink bandwidth of the OLT's PON port exceeds the guaranteed uplink bandwidth that the OLT can provide, then modify the network configuration.

[0180] The modification of network configuration includes one or more of the following methods:

[0181] Reduce the number of target users under the PON ports of one or more OLTs;

[0182] Upgrade the OLT equipment;

[0183] Adjust the target penetration rate of broadband service packages.
