Description
Technical Field
The disclosure relates to the technical field of communication, and in particular relates to a service board card processing method, a device, electronic equipment and a computer readable medium.
Background
With the continuous development of metropolitan area networks, the voltage power used by operators is increasing. FTTH (Fiber To The Home ) is currently the most common home wired broadband access mode that enables users to access the internet through ONTs (Optical Network Terminal, optical network terminals) deployed in the users' homes. An OLT (Optical LINE TERMINAL) typically deploys several service cards on the OLT, configures registration information of ONTs on the service cards, and interconnects the ONTs deployed at the subscribers through Optical fibers, and the OLT continuously loads power for the service cards to provide FTTH capability. Whereas a service card without configured ONT registration information is referred to as an empty service card, the empty service card cannot provide FTTH capability. However, the OLT also continuously supplies power to these idle service cards, which causes significant power waste.
In one technical scheme, in order to save energy for the idle service board of the OLT apparatus, the OLT apparatus may configure the command to set the energy saving characteristic of the idle service board. After enabling this command, the unused no-load service card is powered down after a predetermined time, e.g., 15 minutes. However, this command requires that the auto-discovery function of the ONT is turned off, which means that the auto-discovery function of the ONT cannot be implemented when an ONT not configured with registration information on the OLT apparatus is connected to the OLT apparatus.
Therefore, in this technical solution, in order to timely open the powered-down service board, the OLT apparatus needs to monitor the registration information of the ONT on the powered-down service board in real time, which results in long-term operation of the OLT apparatus under high load.
It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Fig. 1 illustrates a network architecture diagram of an application scenario of a service card processing method according to some example embodiments of the present disclosure.
Referring to fig. 1, the network architecture includes an OLT cloud management system server 105 and a splitter cloud monitoring system server 110, which are respectively the OLT cloud management system server 105 in the VPN 64668 domain and the splitter cloud monitoring system server 110 in the VPN LDCN domain. The OLT cloud management system server 105 and the splitter cloud monitoring system server 110 are in communication connection with a BRAS (Broadband Remote ACCESS SERVER) 120 through a switch 115, the two cloud servers allocate different domains and IP addresses, meanwhile, a VPN LDCN domain, a VPN 64668 domain and IP corresponding to the two domains are configured on two subinterfaces of the BRAS-120, and interworking of the two servers is realized by configuring a static route on the BRAS-120.
Further, the network architecture further includes an OLT apparatus 135 and an OLT apparatus 145, where the OLT apparatus 135 is connected to the plurality of optical network terminals 150, and the OLT apparatus 135 is communicatively connected to the BRAS-125 through a switch 140, and the BRAS-125 is communicatively connected to the BRAS 130.
Fig. 2 illustrates an architectural diagram of an application scenario of a business card processing method according to some example embodiments of the present disclosure.
Referring to fig. 2, the OLT cloud management system server 105 uses SNMP GET protocol to initiate an instruction to collect ONT registration information and service card protection group information on a service card to the OLT device 135, analyzes a data packet returned by the OLT device 135 through an MIB (MANAGEMENT INFORMATION BASE ) database, extracts no-load service card information of a non-protection group, and performs power-down processing on the no-load service card of the non-protection group by sending an SNMP SET instruction to the OLT device 135.
The OLT cloud management system server 105 uses the SNMP GET protocol to actively initiate an instruction for collecting power-on and power-off information of the service board to the OLT device 135 corresponding to the powered-off service board, analyzes a data packet returned by the OLT device 135 through the MIB database, extracts the power-on and power-off information of the powered-off service board, predicts the power-on probability of the powered-off service board in the next period by using a markov prediction algorithm, and performs routing inspection on the selected board by using a roulette selection policy, wherein the power-on probability of the powered-off service board in the next period corresponds to a sector on a roulette in a roulette, and the larger the probability is, the larger the sector area is, and the easier the system is selected. When the service board card has the registration information of the optical network terminal 150, the service board card is timely powered on by sending an SNMP SET instruction to the OLT apparatus 135, so that not only is the high load caused by the fact that the OLT apparatus monitors registration data in real time avoided, but also the timely opening of the FTTH service is ensured.
The optical splitter cloud monitoring system server 110 collects an optical splitter construction work order initiated by a constructor, extracts the time of the order in the optical splitter construction work order, the IP address of the optical splitter uplink OLT and the service board card information, and sends the information to the OLT cloud management system server 105. When the OLT cloud management system server 105 finds that a new optical splitter exists on the service board that has been powered down, the service board is powered up in time by sending an SNMP SET instruction to the OLT device 135.
According to the technical scheme of the embodiment of the disclosure, the access network equipment OLT is used as a core, and the access network equipment OLT interacts with the OLT cloud management system server and the optical splitter cloud monitoring system server in real time, so that on one hand, the security of the OLT protection group service board card is ensured, and the power-down of the idle service board card is not influenced; on the other hand, the closed service board card can be opened in time to ensure the real-time opening of the FTTH service, and the load of the OLT equipment is reduced; on the other hand, the light measurement of the newly built beam splitter by constructors is not affected, and the aims of accurate consumption reduction can be achieved.
Fig. 3 illustrates a flow diagram of a business card processing method according to some example embodiments of the present disclosure. The execution subject of the service card processing method provided by the embodiment of the present disclosure may be a computing device having a computing processing function, such as the server 105 in fig. 1 and 2. The service board processing method includes steps S310 to S340, and the service board processing method in the exemplary embodiment is described in detail below with reference to the accompanying drawings.
In step S310, the power-on and power-off information of at least one powered-off service board of the OLT apparatus is extracted.
In an example embodiment, the OLT cloud management system server 105 uses the SNMP GET protocol to actively initiate an instruction for collecting power-on and power-off information of the service board to the OLT device 135 corresponding to the powered-down service board, analyzes a data packet returned by the OLT device 135 through the MIB database, and extracts the power-on and power-off information of the powered-down service board.
In step S320, the power-on probability of each powered-down service card in the next period is determined based on the power-on and power-off information.
In an example embodiment, based on the power-on and power-off information, a Markov prediction model is adopted to determine the power-on probability of each powered-off service board card in the next time period.
For example, the current state of each powered-down service board card is determined based on the uplink and downlink information, the power-up probability of the powered-down service board card in the next time period is determined by adopting a markov prediction model based on the current state and a state transition probability matrix, and the state transition probability matrix is obtained according to historical uplink and downlink information statistics of each powered-down service board card.
In step S330, the powered down service cards are inspected based on the power up probabilities of the powered down service cards.
In an example embodiment, powered down service cards are selected based on the power up probabilities of the respective powered down service cards; and inspecting the selected powered-down service board card to determine whether ONT registration information exists on the powered-down service board card.
For example, the selected board card is inspected by a roulette selection strategy, wherein the power-on probability of the powered-down service board card in the next period corresponds to a sector on the roulette in the casino, and the larger the power-on probability, the larger the sector area is, and the easier it is to select.
In step S340, if the ONT registration information exists on the powered down service board, the powered down service board is powered up.
In an example embodiment, an OLT cloud management system server patrols and examines a service board card selected by a roulette selection policy, and when there is registration information of an optical network terminal on the service board card, the service board card is timely powered on by sending an SNMP SET instruction to OLT equipment.
According to the technical scheme in the example embodiment of fig. 3, the power-on and power-off information of the service board card of the OLT apparatus is extracted, the power-on probability of the powered-off service board card in the next period is predicted, the selected board card is inspected based on the power-on probability, and when the service board card has the optical network terminal registration information, the service board card is powered on in time, so that the high load caused by the fact that the OLT apparatus monitors the ONT registration data in real time is avoided, and the timely opening of the FTTH service is ensured.
Fig. 4 shows a flow diagram of a method of processing a service card according to further example embodiments of the present disclosure.
In step S401, the OLT cloud management server adds a MIB database.
In an example embodiment, the MIB database of the OLT apparatus is added to the OLT cloud management system server to make the acquired information readable, which is also a precondition for operating the OLT apparatus.
In step S402, the OLT apparatus adds an SNMP-AGENT, an apparatus read/write password, and an SNMP access address.
In an example embodiment, the OLT device adds an IP of SNMP-AGENT. The IP address of the OLT cloud management system server serving as the SNMP-AGENT is added to the OLT equipment so that the OLT can upload information to the OLT cloud management system server.
Further, the OLT device adds a SNMP-AGENT read password. Only if the read password of the SNMP-AGENT is added into the device, the OLT cloud management system server can read information from the OLT device.
The OLT device adds the SNMP-AGENT write password. Only if the writing password of the SNMP-AGENT is added into the equipment, the OLT cloud management system server can perform energy-saving operation on the service board card of the OLT equipment.
The OLT device adds an IP-ACCESS of SNMP. And adding an IP address of the OLT cloud management system server to the OLT equipment as an access IP of the SNMP so that the OLT cloud management system server obtains acquisition rights of the OLT equipment and the service board card information.
In step S403, the OLT cloud management server system extracts service board information.
In an example embodiment, in step S303, the OLT cloud management system server uses the SNMP GET instruction to automatically initiate an instruction for collecting on-service-card ONT registration information and service-card protection group information to the OLT device, and analyzes a data packet returned by the OLT device through the MIB database to extract non-protection-group no-load service-card information.
In step S404, the OLT cloud management server system sends an SNMP-SET instruction to close the non-protected group no-load service board.
In an example embodiment, the OLT cloud management system server performs power-down processing on the idle service cards of the non-protection group by sending an SNMP SET instruction to the OLT.
In step S405, the OLT cloud management server system extracts power-on/power-off state transition information of the powered-down service board card.
In an example embodiment, an OLT cloud management system server uses an SNMP GET protocol to initiate an instruction for collecting power-on and power-off information of a service board to an OLT device corresponding to a powered-down service board, analyzes a data packet returned by the OLT device through a MIB database, and extracts power-on and power-off state conversion information of the powered-down service board.
In step S406, the probability that the powered down service card is powered up in the next period is predicted based on the markov prediction algorithm.
In an example embodiment, a Markov prediction algorithm is used to predict the probability that a powered down service card will power up in the next period of time. The OLT device has very strict requirements on its load, and when the CPU utilization is continuously higher than 80%, the ONT auto-discovery function is affected, and a large amount of packet loss is generated in packet forwarding, so that the service quality of the OLT device will be drastically reduced.
In order to avoid the influence of the load caused by the fact that the OLT equipment monitors the power-down board in full-scale in real time, before the registration information of the optical network terminal on the powered-down service board is monitored, the service board with high power-up probability in the next period needs to be selected in advance for detection. Generally, the phenomenon that a service card is powered up in the next period of time usually occurs after the service card is turned from the powered-up state to the powered-down state, i.e. the phenomenon is related to the conversion state of the current card, and is independent of the conversion state before the card, and the phenomenon satisfies the markov process. Thus, a mathematical model based on a Markov prediction method is used for predicting the power-on probability of the powered-down service board card in the next time period.
In an example embodiment, a powered-down service board is randomly selected, the power-up probability of the service board is R 1、R2、…、RN, meanwhile, the inspection period T of the OLT cloud management system server is equally divided into M time periods, the time at the end of each time period is T 1、T2、…、TM, the power-up probability of the service board corresponding to T k is denoted as P (R i)k, where k=1, 2, …, M, i=1, 2, …, n. for the current time, the probability that the powered-down service board changes from R i to R j at the next time is referred to as the state transition probability that the powered-down service board needs to be powered up at the next time, and is represented by formula (1):
P(Ri→Rj)＝P(Rj/Ri)＝Pij (1)
The state transition probability matrix P is the following formula (2):
The matrix P is called a one-step state transition probability matrix that the powered-down service board card needs to be powered up at the next moment. This matrix P represents the size of the likelihood that the powered down service card will need to be powered up at the next time from the current time. Wherein all the state transition probabilities P ij in the matrix satisfy the equation (3):
Wherein, defining P ij (k) as the probability that the power-on probability R i of the powered-down service board card is changed into R j after k steps of transition, and according to the Markov prediction method model, P ij (k) satisfies the formula (4):
Wherein, The k-step state transition probability matrix of the powered-down service board card is called, namely the probability prediction matrix of the powered-down service board card at the kth moment.
