To facilitate an understanding of the present application, reference will now be made to the description of the related concepts related to the embodiments of the present application.
Fiber access (fiber to the X, FTTX)
Fiber access is a new generation of broadband network approach for connecting subscribers and operators. The broadband network of FTTX mainly includes a metropolitan area network and an access network. The equipment in the metropolitan area network mainly comprises: broadband Remote Access Server (BRAS) devices, Service Router (SR) devices, Content Delivery Network (CDN) devices that sink from the service platform side to the metro network, number line resource management systems, Element Management Systems (EMS), and service support systems (BSS). The equipment in the access network mainly comprises: optical Line Terminal (OLT) devices, Optical Distribution Network (ODN) devices, and Customer Premises Equipment (CPE). Each of the above-described apparatuses is described in detail below.
BRAS equipment
BRAS equipment is a novel access gateway for broadband network applications. In the embodiment of the present application, the present application is mainly used for accessing a point to point protocol over ethernet (PPPOE) service (for example, a service for dial-up networking through an optical modem or a digital subscriber line modem) on an ethernet of a user terminal; PPPOE is a network tunneling protocol that encapsulates point-to-point protocol (PPP) in an ethernet (ethernet) framework.
The BRAS device is mainly used for receiving and terminating at least one of a PPPOE message, managing the online and offline of a PPPOE user (subscriber), allocating a quality of service (QoS) or Internet Protocol (IP) address of the PPPOE user, converting a private network IP address allocated to the user into a public network IP address or forwarding a route, enabling the PPPOE user to connect to the internet (which may also be called as "accessing the internet/internet") through a PPPOE service (which may also be called as "PPPOE dial"), and using a service provider or a content provider. The ports of the BRAS device connected to network cards (also referred to as "line cards") are typically ethernet interfaces, for example, interfaces of optical modules such as 10GE and 100 GE. The PPPOE service may also be referred to as "broadband service" (one of the basic telecommunications services), or "PPPOE broadband service", or "dial-up internet service".
CDN device
The CDN device is an intelligent virtual network device constructed on the basis of the existing broadband network, and enables a user to obtain required content nearby through functional modules of load balancing, content distribution, scheduling and the like of a central platform by means of edge servers deployed in various places, so that network congestion is reduced, and the access response speed and hit rate of the user are improved. In order to reduce the bandwidth pressure of a backbone network and end-to-end delay, CDN devices are gradually pushed to the edge, and domestic operators develop to sink the construction of CDN device nodes to the edge of a metropolitan area network service control layer, such as SR devices. In this embodiment, the CDN device is mainly used to distribute or schedule an IPTV service of an Internet Protocol Television (IPTV) service platform and a Virtual Reality (VR) service of a VR service platform.
SR apparatus
The SR device is a device applied to a high-end router of a metropolitan area network.
The SR device is mainly used for managing at least one of an Internet Protocol Over Ethernet (IPOE) user, allocating an IPOE address or QoS, and forwarding multi-protocol label switching (MPLS). In the embodiment of the application, the SR device is mainly used for accessing an IPTV service and a VR service. The ports of the SR device connected to network cards (also referred to as "line cards") are typically ethernet interfaces, such as interfaces of optical modules like 10GE and 100 GE. The CPE accesses a telecom value-added service platform (value-added service in an intranet of a telecom operator) such as IPTV service and VR service through SR equipment.
OLT equipment
An OLT device is a terminal device used to connect a fiber trunk. The OLT is a local end device in a Passive Optical Network (PON) system, and is connected to an Optical Network Unit (ONU) device in the PON system through an ODN device (also referred to as an "ODN network"). The OLT equipment comprises an upper connection board card and a lower connection board card.
In this embodiment of the application, an uplink board card in the OLT device includes a plurality of ports, the ports of the uplink board card in the OLT device are usually ethernet interfaces, such as interfaces of 10GE optical modules, and the OLT device communicates with the BRAS device and the SR device through the plurality of ports in the uplink board card. The lower link board card of the OLT device is also referred to as a passive optical network board card. The OLT equipment comprises a plurality of PON board cards, each PON board card comprises a plurality of ports, and the OLT equipment communicates with the ODN equipment through each port of the ports in the PON board cards. The port of the PON board may also be referred to as a "PON port".
ODN equipment
The ODN device is a fiber optic network device in a broadband network of FTTX.
In this embodiment, the ODN device is configured to provide an optical transmission channel between the OLT device and the CPE. The ODN device employs a point-to-multipoint master station (P2 multiple point, P2MP) topology. The ODN device includes one or more passive optical splitters (also referred to as "splitters"). In actual network construction, the number of optical splitters included in an ODN device is usually not more than two in consideration of optical path loss. The ODN device includes an optical fiber connecting the OLT device and the CPE, and an optical splitter between the optical fibers.
Light splitter
The optical splitter is composed of an incident slit, an emergent slit, a reflecting mirror and a dispersion element and is mainly used for separating out required resonance absorption lines.
Optical splitters are commonly used for coupling, branching, and distributing optical signals. For example, a 1:4 optical splitter (one optical fiber interface near the input end of the network side, and 4 optical fiber interfaces near the output end of the user side), one end of which is connected to one PON port of the OLT device on the network side, and the other end of which is connected to the upstream interfaces of 4 CPEs on the user side (i.e., at most 4 users can be connected, and each CPE has one upstream interface). The ODN device may be connected in series with a plurality of optical splitters, and the split ratio of the ODN device is the product of the split ratios of all the optical splitters in the ODN device.
CPE
The CPE is often deployed at the client of FTTX traffic and is a terminal that connects a device in a home network or a device in an enterprise network to an ODN device. For example: ONU equipment of the FTTX network. The ONU device may be a home gateway for a home user or an enterprise gateway for an enterprise user. The CPE is connected with the PON network on the upper part and specific service equipment (such as a PC (personal computer), a set top box, a VR (virtual reality) helmet and the like) on the lower part, so that the connection between the access network and the user equipment is completed, and PPPOE service, IPTV service, VR service and the like are provided for users.
For example, after a Personal Computer (PC) is connected to a CPE, in order to access the internet/internet, the PPPOE service "dials" to obtain an IP address assigned by the BRAS device, which may be the PC or the CPE (i.e., the PC or the CPE serves as a client of the PPPOE). Whether the device is a PC or a CPE depends on the operator's traffic and network configuration. After the set-top box is connected with the CPE and passes through the request of the IPTV service, the set-top box or the CPE obtains an IP address (of the IPTV service) from the SR equipment in an IPOE mode. After the VR headset is connected with the CPE, in order to perform a request of a VR service, the VR headset or the CPE obtains an IP address of the VR service from the SR device through an IPOE mode or a Dynamic Host Configuration Protocol (DHCP). And under the condition that the CPE respectively obtains the service IP addresses allocated by the BRAS equipment and the SR equipment, the CPE allocates the addresses to the PC, the set-top box and the VR helmet through a DHCP protocol.
In the embodiment of the application, one user only corresponds to one CPE. "one user subscribes to the PPPOE service, the IPTV service, and the VR service" is equivalent to "the CPE device of the user subscribes to the PPPOE service, the IPTV service, and the VR service". The traffic generated by a customer is identical to the traffic generated by the customer's CPE. The service used by the user (such as PPPOE service) is equal to the service used by the CPE of the user (such as PPPOE service).
Number line resource management system
The signal line resource management system is used for storing at least one of topology of the ODN equipment, position and length of optical fibers contained in the ODN equipment, number of optical splitters contained in the ODN equipment, splitting ratio of the optical splitters corresponding to the ODN equipment, number of ports reserved by the optical splitters of the ODN equipment, occupation condition of ports of the ODN equipment or use condition of the ODN equipment. In this embodiment of the present application, the device configured with the broadband network may obtain the preset number of CPEs accessing the ODN device according to the split light of the ODN device and the number of ports on the user side reserved by the ODN device. The number line resource management system is one of subsystems of an Operation Support System (OSS) of an operator.
Network element management system
The network element management system is a special network manager of the network equipment. The BRAS device, SR device, OLT device, and ONU typically have their own network element management systems. The network element management system interacts with the network device through a Simple Network Management Protocol (SNMP) so as to obtain at least one of configuration information, user traffic information or user quantity information of the network device. The network element management system is one of the subsystems of the operation support system. In the embodiment of the present application, data information of a network device (such as at least one of configuration information of the network device, user traffic information, or user quantity information) may be directly obtained from the network device (such as BRAS device, SR device, OLT device, and ONU device), or may also be obtained from a corresponding network element management system of the network device. In the embodiment of the present application, a manner of obtaining data information of a network device is not limited.
Business support system
A service support system (BSS) generally includes subsystems for operator charging, settlement, accounting, customer service and business. In the embodiment of the application, data related to a service ordered by a user, such as PPPOE service, IPTV service, and VR service, is mainly obtained through a service support system business subsystem. The business subsystem accepts the subscribed business of the user and stores the data of the relevant user and business.
Currently, the way broadband networks are accessed in fiber is a new generation of ways for connecting terminals and operators. Due to the popularization of the FTTX network architecture, how to configure devices in the FTTX network architecture and avoid bandwidth bottlenecks in the broadband network are problems that operators need to solve when deploying the FTTX network architecture.
At present, an operator usually checks each network element in an FTTX network architecture and adjusts and expands network bandwidth of the FTTX after at least one of BRAS equipment, SR equipment, OLT equipment, or ODN equipment sends alarm information that traffic exceeds a threshold to operation and maintenance personnel, or receives a complaint from a user. However, this method of configuring a broadband network is inefficient.
In view of the foregoing problems, an embodiment of the present application provides a method for configuring a broadband network. The device for configuring the broadband network firstly determines the number of the CPEs borne by the upper port side of the OLT equipment according to the preset maximum flow of the upper port side of the OLT equipment, the flow which is generated by the acquired service ordered by the CPE and reaches the upper port side of the OLT equipment through the BRAS equipment and the flow which reaches the upper port side of the OLT equipment through the SR equipment. Then, the apparatus for configuring the broadband network configures the broadband network according to the number of CPEs carried by the upper port side of the OLT device and the obtained number of CPEs accessing the ODN device (e.g., the ODN device connected to the PON board of the OLT device and the preset number of CPEs accessing the ODN device, which are obtained from the number line resource management system).
It can be seen that, the apparatus for configuring the broadband network may determine the performance of the current broadband network based on the number of CPEs carried on the upper port side of the OLT device and the number of CPEs accessing the ODN device, and configure the broadband network according to the performance of the current broadband network. Compared with the prior art, the method and the device for configuring the broadband network can find the performance of the broadband network in advance and perform corresponding configuration before user perception, and solve the technical problem that the existing method for configuring the broadband network is low in efficiency.

The following describes a method for configuring a broadband network according to an embodiment of the present application in detail with reference to the accompanying drawings.
Fig. 4 is a flowchart illustrating a method for configuring a broadband network according to an embodiment of the present application. The method of configuring a broadband network may be applied to the network bandwidth configuration system 10 shown in fig. 1. The method of configuring a broadband network includes S401-S411.
S401, the device for configuring the broadband network obtains the PPPOE service parameters.
Specifically, if the CPE subscribes to the PPPOE service through the BSS, the service parameter of the PPPOE is sent to the BRAS device. Therefore, the device for configuring the broadband network can acquire the PPPOE service parameters from the BRAS equipment or the network element management system of the BRAS equipment. The PPPOE service parameters comprise: the number of CPEs subscribing to PPPOE service and the number of CPEs currently using PPPOE service.
Optionally, the dial-up networking service may be a PPPOE service, or an ipoe (internet protocol over ethernet) service. If an operator provides dial-up networking services for a user (i.e., a CPE) through a multi-service router (MSR), and a PPPOE service subscribed by the CPE can be directly replaced with an IPOE service, a device configured with a broadband network can acquire an IPOE service parameter from MSR equipment (i.e., a BRAS equipment is directly replaced with MSR equipment). The acquiring method refers to a method for acquiring the PPPOE service parameters by a device configured with a broadband network, and is not described herein again. The embodiment of the present application takes the example that the CPE subscribes to the PPPOE service.
S402, the device for configuring the broadband network acquires IPTV service parameters and VR service parameters.
The IPTV service comprises an IPTV on-demand service and an IPTV live broadcast service.
Because the CDN device sinks (i.e., stores) the content and configuration parameters of the video and the like of the IPTV service platform and the VR service platform to the metropolitan area network side, the CDN device also reserves (i.e., stores) the IPTV on-demand service parameter, the IPTV direct broadcast service parameter, and the VR service parameter. If the CPE subscribes to the IPTV service and the VR service, the device configured with the broadband network may obtain the IPTV on-demand service parameter, the IPTV live broadcast service parameter, and the VR service parameter from the CDN device, and may also obtain the IPTV on-demand service parameter, the IPTV live broadcast service parameter, and the VR service parameter from the IPTV service platform and the VR service platform.
The IPTV on-demand service parameter, IPTV live broadcast service parameter, and VR service parameter include: the total flow of IPTV on-demand services in a unit time (i.e. the total flow of IPTV on-demand services in the CDN device), the number of CPEs requesting IPTV on-demand services in a unit time (i.e. the total number of concurrent IPTV users in the CDN device), the number of CPEs currently using IPTV on-demand services, the number of CPEs currently using VR services, the reserved bandwidth of an uplink port of the OLT device for IPTV live broadcast services, the total flow of VR services in a unit time, the number of CPEs requesting VR services in a unit time, and the like. Optionally, the total traffic in the CDN device and the total number of concurrent users in the CDN device may be obtained by sampling the CDN device in one area.
Since the IPTV service and the VR service are telecom value added services and the PPPOE service is a telecom basic service, the device configured with the broadband network can obtain, from the BSS, the permeability of the IPTV on-demand service, the permeability of the IPTV live broadcast service, the permeability of the IPTV service and the permeability of the VR service, the number of CPEs subscribing to the IPTV on-demand service, the number of CPEs subscribing to the VR service, and the like.
Optionally, the penetration rate of the IPTV on-demand service is equal to the number of CPEs of the CDN device registered for the IPTV service/the number of CPEs of the PPPOE service in the BRAS device. The number of CPE of the registered IPTV service of the CDN equipment is obtained from the CDN equipment, and the number of CPE of the PPPOE service in the BRAS equipment is obtained from the BRAS equipment.
Optionally, the permeability of the VR service is equal to the number of CPEs registered for the VR service in the CDN device/the number of CPEs registered for the PPPOE service in the BRAS device. The number of CPE of the registered VR service of the CDN equipment is obtained from the CDN equipment, and the number of CPE of the PPPOE service in the BRAS equipment is obtained from the BRAS equipment.
Specifically, if the CPE subscribes to the IPTV on-demand service, the device configured with the broadband network first acquires an IPTV on-demand service parameter from the IPTV service platform. The IPTV on-demand service parameters comprise: the number of the CPEs subscribing to the IPTV on-demand service, the number of the CPEs currently using the IPTV on-demand service, the number of the CPEs using the IPTV on-demand service in a first preset time period, the number of the CPEs requesting the IPTV service in a unit time and the total flow rate of the IPTV on-demand service in a unit time. The first preset time period is a time period in which the number of CPEs using the IPTV on-demand service per day is the largest, for example: 19 per day: 00-22:00. The unit time may be several minutes, several hours, or several days, which is not limited herein.
If the CPE orders the IPTV live broadcast service, the device for configuring the broadband network firstly acquires the IPTV live broadcast service parameters from the IPTV service platform. The IPTV live broadcast service parameters comprise: the video bitrate of each program source in the multiple IPTV live program sources (or the video bitrate of the program source with each video resolution, the number of the program sources with each video resolution), and the preset coefficient of the IPTV live program service.
If the CPE orders VR service, the device for configuring the broadband network firstly acquires VR service parameters from the VR service platform. The VR service parameters include: the number of CPEs subscribing to VR traffic, the number of CPEs currently using VR traffic, the number of CPEs requesting VR traffic per unit time, and the total traffic of VR traffic per unit time.
In this embodiment of the present application, the apparatus configured with the broadband network may first execute S401 and then execute S402; or executing S402 first and then executing S401; s401 and S402 may also be executed simultaneously, which is not limited herein.
S403, the device for configuring the broadband network acquires the first flow.
The first flow is the flow which is generated by the service subscribed by the CPE and reaches the upper port side of the OLT equipment through the BRAS equipment. Since the traffic reaching the upper port side of the OLT device via the BRAS device is PPPOE traffic, the first traffic is traffic reaching the upper port side of the OLT device via the BRAS device. Hereinafter, for convenience of description, the first traffic is collectively referred to as a first flow.
Specifically, first, the device configured with the broadband network determines the concurrency rate of the PPPOE service according to the number of CPEs subscribing the PPPOE service and the number of CPEs currently using the PPPOE service, which are acquired from the BRAS device. The concurrency rate of the PPPOE service meets the formula 1:
the concurrency rate of the PPPOE service is equal to the number of CPE currently using the PPPOE service/the number of CPE ordering the PPPOE service; (equation 1).
Wherein, the number of the CPEs currently using the PPPOE service is the number of the CPEs currently using the PPPOE service and generating the data traffic. Generally, if only the flow generated by the heartbeat for maintaining the PPPOE session is between the CPE and the BRAS device, the CPE does not count the number of CPEs currently using PPPOE service. The number of CPEs currently using PPPOE service is the number of CPEs using PPPOE service in a certain period of time.
Then, the device configured with the broadband network acquires the preset average bandwidth of the PPPOE service. The preset average bandwidth of the PPPOE service is set by an operator according to factors such as the current carrying capacity of network equipment, market demands, supervision policies and the like when planning a broadband network, and the preset average bandwidth of the PPPOE service of the CPE equipment connected and managed by the BRAS equipment.
And then, the device for configuring the broadband network determines the first flow according to the concurrency rate of the PPPOE service and the preset average bandwidth of the PPPOE service. The first flow rate satisfies a first calculation:
the first traffic is a preset average bandwidth of PPPOE traffic, and the concurrency rate of PPPOE traffic.
Illustratively, the number of the PPPOE subscribed terminals obtained from the BRAS device by the broadband network configuring device is 100. The bandwidth of the number of the terminals currently using the PPPOE service, which is acquired from the BRAS equipment by the broadband network configuration device, is 50. First, the apparatus configured with the broadband network may determine that the concurrency rate of the PPPOE service is 50/100-50%, then, the apparatus configured with the broadband network acquires a preset average bandwidth of the PPPOE service of 1000 megabits per second (Mbps), and then may determine that the first traffic is 1000 Mbps-50% — 500 Mbps.
S404, the device for configuring the broadband network acquires the second flow.
And the second flow is the flow which is generated by the service ordered by the CPE and reaches the upper port side of the OLT equipment through the SR equipment. Since the service reaching the upper port side of the OLT device via the SR device is a service issued by the CDN device to the SR device, and the services reaching the SR device via the CDN device are an IPTV service and a VR service. Therefore, the second traffic is the traffic of the IPTV traffic and VR traffic arriving at the upper-interface side of the OLT device via the SR device. Hereinafter collectively referred to as the second traffic for ease of description.
Specifically, for the IPTV on-demand service, the device configured with the broadband network determines the average bandwidth of the IPTV on-demand service according to the number of CPEs that subscribe the PPPOE service and are obtained in S401, and according to the number of CPEs that subscribe the IPTV on-demand service and are obtained in S402, the number of CPEs that currently use the IPTV on-demand service, the number of CPEs that use the IPTV on-demand service in the first preset time period, the number of CPEs that request the IPTV on-demand service in one unit time, and the total flow rate of the IPTV on-demand service in one unit time.
Optionally, the permeability of the IPTV on-demand service satisfies the following formula 2, the concurrency rate of the IPTV on-demand service satisfies the following formula 3, the average flow rate of the IPTV on-demand service used by the CPE in a unit time satisfies the following formula 4, and the average bandwidth of the IPTV on-demand service satisfies the following formula 5.
The penetration rate of the IPTV on-demand service is equal to the number of CPE ordering the IPTV on-demand service/the number of CPE ordering the PPPOE service; (equation 2).
The concurrency rate of the IPTV on-demand service is equal to the number of CPE currently using the IPTV on-demand service/the number of CPE subscribing the IPTV on-demand service; (equation 3).
The average flow rate of the IPTV on-demand service used by the CPE in a unit time is equal to the total flow rate of the IPTV on-demand service in a unit time/the number of the CPE requesting the IPTV on-demand service in a unit time; (equation 4).
The average bandwidth of the IPTV on-demand service is equal to the permeability of the IPTV on-demand service and the concurrency rate of the IPTV on-demand service and the average flow of the IPTV on-demand service used by the CPE in a unit time; (equation 5).
Illustratively, the preset unit time is 2 hours, preferably the peak time of the IPTV service. The device for configuring the broadband network obtains 200 CPEs for ordering PPPOE services according to S401; the permeability of the IPTV on-demand service obtained according to the S402 is 80%; calculating according to the data acquired in S402: the concurrency rate of the IPTV on-demand service is 50%, and the average flow rate of the IPTV on-demand service used by the CPE in one unit time is 100 Mbps. The average bandwidth of the IPTV on-demand service is 100Mbps by 80% by 50% by 40 Mbps.
For IPTV live broadcast service, a multicast technology is adopted in a network, and generally, a multicast traffic replication point of the IPTV live broadcast service pushes a live broadcast program (i.e., multicast traffic) from a metropolitan area network to an uplink port side of an OLT device through a Protocol Independent Multicast (PIM) or other multicast routing protocol at an OLT device, i.e., a CDN device or an IPTV platform, and the OLT device replicates a live broadcast video stream for each CPE requesting an IPTV live broadcast channel according to an Internet Group Management Protocol (IGMP) or other protocol.
The device for configuring the broadband network obtains from an IPTV service platform or CDN equipment: reserving bandwidth at an upper connection port of OLT equipment by IPTV live broadcast service; that is, the CDN device uniformly pushes the video stream to the OLT device. According to the resolution of video (channel), the bandwidth reserved at the uplink port of the OLT device for IPTV live broadcast service can be divided into three cases, i.e. low, medium, and high bandwidths, as follows: 700Mbps, 1000Mbps, 1500 Mbps. Optionally, the bandwidth reserved at the uplink port of the OLT device for the IPTV live broadcast service is related to the following parameters: the method comprises the steps of standard definition IPTV live broadcast CPE (namely, a user involved in the application) ratio, standard definition video rate, high definition video IPTV live broadcast CPE (namely, a user involved in the application) ratio, high definition video rate, 4K definition IPTV live broadcast CPE (namely, a user involved in the application) ratio, 4K definition IPTV video rate and the concurrency number of IPTV live broadcast channels requested by CPE under the OLT equipment in a peak period. The video ratio of each resolution can be collected in the IPTV service platform. The concurrent number of the IPTV live broadcast channels requested by the CPE at the peak time can be collected at the OLT device (for example, the number of multicast addresses in the concurrent IGMP join message received by the OLT device from the CPE, that is, the number of multicast addresses in the IGMP join message in a period of time, is collected at the peak time; one multicast address represents one IPTV live broadcast channel).
Optionally, the average rate of the IPTV live broadcast CPEs is equal to the video rate of the standard definition CPEs ratio of the standard definition resolution + the video rate of the high definition IPTV live broadcast users ratio of the high definition user ratio + the video rate of the 4K resolution of the IPTV live broadcast users ratio of the 4K resolution.
The bandwidth reserved by an upper connection port of the OLT equipment for the IPTV live broadcast service is equal to the average speed of IPTV live broadcast CPE (customer premise equipment) and the concurrency number of IPTV live broadcast channels requested by the CPE under the OLT in the peak period.
For the VR service, the device configured with the broadband network determines the average bandwidth of the VR service according to the number of CPEs subscribing to the PPPOE service, which is obtained in S401, and according to the permeability of the VR service, the number of CPEs currently using the VR service, the number of CPEs subscribing to the VR service, the number of CPEs requesting the VR service in a unit time, and the total flow rate of the VR service in a unit time, which are obtained in S402. The concurrency rate of the VR service meets the following formula 6, the average flow of the VR service used by the CPE in a unit time meets the following formula 7, and the average bandwidth of the VR service meets the following formula 8.
The concurrency rate of the VR service is equal to the number of CPE currently using the VR service/the number of CPE subscribing the VR service; (equation 6).
The average flow rate of the VR service used by the CPE in a unit time is equal to the total flow rate of the VR service in a unit time/the number of the CPE requesting the VR service in a unit time; (equation 7).
The average bandwidth of the VR service is the permeability of the VR service and the concurrency rate of the VR service is the average flow of the VR service used by CPE in a unit time; (equation 8).
After the average bandwidth of the IPTV on-demand service and the average bandwidth of the VR service are determined, the device for configuring the broadband network determines a second flow according to the average bandwidth of the IPTV on-demand service and the average bandwidth of the VR service. Wherein the second flow satisfies a second calculation:
and the second flow is the average bandwidth of IPTV on-demand service plus the average bandwidth of VR service.
In this embodiment of the present application, the device configured with the broadband network may first perform S403 and then perform S404; or executing S404 first and then executing S403; s403 and S404 may also be performed simultaneously, but are not limited herein.
S405, the device configured with the broadband network acquires the preset maximum flow at the upper port side of the OLT equipment.
The upper port side of the OLT device includes a plurality of ports (e.g., ports with a rate of 10GE, 100GE, etc.), and the number of the ports on the upper port side of the OLT device is proportional to the maximum flow rate on the upper port side of the OLT device. Therefore, when planning a broadband network, an operator may determine the preset maximum flow rate on the upper interface side of the OLT device according to the number of ports (of each specification) on the upper interface side of the OLT device, the specification of each port, and the threshold of the flow rate of each port.
In this embodiment of the present application, the device configured with the broadband network may first execute S405 and then execute S401-S404; or S401-S404 can be executed first, and then S405 can be executed; s405 and S401-S404 may also be executed simultaneously, and are not limited herein.
S406, the device for configuring the broadband network determines the number of the CPEs borne by the upper port side of the OLT equipment according to the first flow, the second flow, the preset maximum flow at the upper port side of the OLT equipment and the bandwidth reserved by the IPTV live broadcast service at the upper port of the OLT equipment.
Optionally, the number of CPEs carried by the upper port side of the OLT device satisfies a third calculation equation:
the number of CPEs carried by the upper port side of the OLT device is equal to (preset maximum traffic on the upper port side of the OLT device-bandwidth reserved by IPTV live broadcast service on the upper port of the OLT device)/(first traffic + second traffic).
S407, the device for configuring the broadband network acquires the preset number of the CPEs accessing the ODN equipment.
The board card on the lower port side of the OLT apparatus is also referred to as a PON board card. The OLT device includes a plurality of PON boards, and each PON board includes a plurality of passive optical network ports (which may also be referred to as PON ports).
The device for configuring the broadband network obtains from the OLT equipment: the number M of PON boards of the OLT apparatus.
The device for configuring the broadband network obtains from the number line resource management system: the preset number N of all CPEs connected by the non-reserved ports (i.e. non-reserved PON ports) of each PON board card of the OLT apparatus through the ODN apparatusi(ii) a N is an integer greater than 0; i is more than 0 and less than or equal to M, and i is an integer.
The device for configuring the broadband network connects the preset number N of the CPEs through the ODN equipment according to the number M of the PON boards and the unreserved ports (namely, unreserved PON ports) of each PON board of the OLT equipmentiAnd determining the preset number of CPEs accessing the ODN equipment. The preset number of the CPEs accessing the ODN equipment meets a fourth calculation formula:
n is the preset number of CPE accessed into the ODN equipment1+N2+…+Ni+…NM。
In this embodiment of the present application, the device configured with the broadband network may first execute S407 and then execute S401-S406; or executing S401-S406 first and then executing S407; s407 and S401-S406 may also be executed simultaneously, which is not limited herein.
S408, the device for configuring the broadband network judges the size relationship between the number of the CPEs borne by the upper port side of the OLT equipment and the preset number of the CPEs accessed into the ODN equipment.
If the number of the CPEs carried by the upper port side of the OLT device is greater than the preset number of CPEs accessing the ODN device, S409 is executed. If the number of CPEs carried by the upper port side of the OLT device is less than the preset number of CPEs accessing the ODN device, S410 is executed. If the number of CPEs carried on the upper port side of the OLT device is equal to the preset number of CPEs accessing the ODN device, S411 is executed.
S409, configuring a PON board card of the device capacity expansion OLT equipment of the broadband network.
The device configured with the broadband network expands (increases) the PON board card of the OLT apparatus, i.e., increases the number of PON ports. After the PON board cards are added, X numbers of the PON ports of the PON board cards are connected with the preset number of the CPEs through the ODN equipment, so that the first preset rule is met.
Usually, at least one PON board is added, and the number of PON boards to be added is related to the following situations: the number of PON ports of a PON board card (namely: the density of the PON board card), the splitting ratio of the ODN equipment and X. For example, if X is 56 and the splitting ratio of the ODN device is 1 × 8, the OLT needs to have at least one PON board with 8 PON ports.
Namely: the number of PON ports to be increased is X (1+ ODN port reservation ratio)/splitting ratio of the ODN device; (formula 9)
If the data obtained from equation 9 is non-integer, then rounding up.
The number of PON boards to be increased is equal to the number of PON ports to be increased/the density of the PON boards; and if the data obtained by the calculation formula is not an integer, rounding up.
The first preset rule may be:
the number + X of the CPEs accessed to the ODN equipment is more than or equal to the number of the CPEs borne by the upper port side of the OLT equipment.
If the number of the CPEs carried by the upper port side of the OLT equipment is larger than the preset number of the CPEs accessed to the ODN equipment, expanding the PON board card of the OLT equipment according to a first preset rule, wherein the preset number of the PON board card added after the PON board card of the OLT equipment is expanded and connected with the CPEs through the ODN equipment is X.
It should be noted that, because the number of ports of one PON board card (PON board card density) of the OLT apparatus is usually 4, 8, and 16, and if the number of PON ports to be added is 10 according to formula 9, that is, 10 ports need to be added, in practical application, there is no board card with 10 ports, and one board card usually has 8 ports, or 16 ports, so that a board card with 16 ports can be added; the effect that the number of the CPEs carried by the upper port side of the OLT equipment is matched with the number of the CPEs accessed into the ODN equipment is achieved.
And S410, configuring an upper port side port of the device capacity expansion OLT equipment of the broadband network.
And the device configured with the broadband network expands the port at the side of the upper port of the OLT device, and the preset flow at the side of the upper port increased after expansion is Y so as to meet a second preset rule.
If the number of the CPEs carried by the upper port side of the OLT device is smaller than the preset number of the CPEs accessed to the ODN device, it indicates that the number of the CPEs carried by the upper port side of the OLT device cannot satisfy the requirement that more CPEs are accessed to the ODN device, and thus, the port of the upper port side of the OLT device can be expanded. The capacity expansion method comprises the following steps: increasing the number of the OLT upper connection port board cards, wherein after the number of the OLT upper connection port board cards is increased, the increased preset flow of the OLT upper connection port is not less than Y; or, replacing the optical module of the uplink interface of the OLT with an optical module of a higher speed specification, for example, replacing the optical module of 10GE with a module of 100GE, requires support of the OLT device.
The second preset rule may be:
[ (the preset maximum flow at the upper port side of the OLT equipment-the reserved bandwidth + Y)/(the first flow + the second flow) of the IPTV live broadcast service at the upper port of the OLT equipment) ] > or more than the number of the CPE accessing the ODN equipment.
It should be noted that:
the preset maximum flow on the upper connection port side of the OLT equipment is equal to the sum of theoretical capacities of the upper connection ports and a threshold value; (formula 10)
In the formula 10, the sum of the theoretical capacities of the uplink ports is data calculated by all the uplink ports of the OLT device according to the specification of the optical module of the OLT device, and if the OLT device has 3 uplink ports of 10GE, the sum of the theoretical capacities of the uplink ports is equal to 30 GE; an exemplary threshold is 60%.
The following are exemplary: if Y ≈ 50GE is obtained by the above-described second preset rule, Y/threshold value ≈ 83.333.
For example, one 100GE uplink port (optical module) or 9 10GE uplink ports (optical modules) may be selected and added according to the number of spare uplink ports of the OLT device and the optical modules that can be used by the uplink ports; the effect that the number of the CPEs carried by the upper port side of the OLT equipment is matched with the number of the CPEs accessed into the ODN equipment is achieved.
S411, the device configuring the broadband network does not perform any operation.
The embodiment of the application provides a method for configuring a broadband network, and a device for configuring the broadband network determines the number of CPEs borne by an upper port side of OLT equipment according to preset maximum flow of the upper port side of the OLT equipment and acquired flow which is generated by service ordered by the CPEs and reaches the upper port side of the OLT equipment through BRAS equipment and flow which reaches the upper port side of the OLT equipment through SR equipment; and then, the device for configuring the broadband network configures the broadband network according to the number of the CPEs carried by the upper port side of the OLT equipment and the obtained number of the CPEs accessed to the ODN equipment. It can be seen that, the apparatus for configuring the broadband network may determine the performance of the current broadband network based on the number of CPEs carried on the upper port side of the OLT device and the number of CPEs accessing the ODN device, and configure the broadband network according to the performance of the current broadband network.
