QoS (quality of service) is the quality of service. For network traffic, the quality of service includes transmission bandwidth, transmission delay, packet loss rate of data, and the like. In the network, the service quality can be improved by ensuring the transmission bandwidth, reducing the transmission time delay, reducing the packet loss rate of data, reducing the time delay jitter and other measures. As network resources are limited, quality of service requirements arise as long as there is a robbery of network resources. The quality of service is relative to network traffic, and may be at the expense of the quality of service of other traffic while ensuring the quality of service of certain types of traffic. For example, in the case of a fixed network total bandwidth, if a certain type of service occupies more bandwidth, the less bandwidth can be used by other services, which may affect the use of other services. Therefore, the embodiment reasonably plans and allocates the network resources according to the network QOS strategy (such as the characteristics of various services), so that the PTN network resources are efficiently utilized.

the target monitoring objects of the first type monitoring points are as follows:
the target monitoring objects of the third type monitoring points are as follows:
the target monitoring objects of the fifth type monitoring points are as follows:
the following is a detailed description of the practical implementation of the above method:
as shown in fig. 2, five types of monitoring points are set for the PTN network:
the first-class monitoring points are arranged on equipment which can be directly interacted with a core network element (such as S-GW and MME) in a core layer, and are mainly used for monitoring total traffic on a UNI port of the equipment where the first-class monitoring points are arranged and used for interacting with the core network element and each service traffic (such as traffic of S1 service) transmitted by the UNI port;
the second type monitoring point is arranged on any device in the core layer, and mainly monitors the traffic between the device where the second type monitoring point is located and other devices in the core layer, that is, the total traffic of an NNI port of the device, and specifically, the second type monitoring point can respectively monitor the S1 traffic and the X2 traffic between the device where the second type monitoring point is located and other devices in the core layer, and can also perform multi-level traffic monitoring on the second type monitoring point, for example, respectively monitor the LSP traffic and the PW traffic on a transmission channel between the device where the second type monitoring point is located and other devices in the core layer. Preferably, the second type monitoring points are arranged on equipment which can directly interact with a core network element in a core layer, and at the moment, the total flow of the equipment which the second type monitoring points belong to on the core layer can be monitored;
the third type of monitoring points are arranged on L2/L3 bridging devices on the boundary between the core layer and the convergence layer, and also can be arranged on other devices in the convergence layer, and are mainly used for monitoring the traffic between the device where the third type of monitoring points are located and the convergence layer device, that is, the total traffic on the NNI port, and specifically, the third type of monitoring points can monitor the S1 service traffic and the X2 service traffic on the NNI port, and also can monitor the total traffic of the S1 service and the total traffic of the X2 service between the device where the third type of monitoring points are located and the convergence layer device; in addition, multi-level traffic monitoring can be performed at the third type of monitoring point, for example, LSP traffic and PW traffic on the transmission channel of the device where the monitoring point is located and the convergence layer device are monitored respectively. Preferably, the monitoring points of the third type are arranged on the L2/L3 bridge device at the boundary of the core layer and the convergence layer, and in this case, the total flow of the convergence layer of the device to which the monitoring points of the third type belong can be monitored.
The fourth type of monitoring point is arranged on equipment for bridging the convergence layer and the access layer, is mainly used for monitoring the traffic between the equipment where the monitoring point is located and the access layer equipment, namely the total traffic on the NNI port, and can specifically monitor the S1 service traffic and the X2 service traffic on the NNI port; in addition, multi-level traffic monitoring can be performed at the fourth type of monitoring point, for example, LSP traffic and PW traffic on the transmission channel of the device where the device is located and the access stratum device are monitored respectively; and monitoring the total flow of the access stratum of the equipment to which the equipment belongs at the fourth type monitoring point.
The fifth monitoring point is arranged on a device which can directly interact with the base station in the access layer, namely a UNI port of the device, mainly monitors the traffic between the device where the fifth monitoring point is located and the base station, and can also monitor S1 service traffic and X2 service traffic on the specific UNI port.
After five types of monitoring points are set, carrying out online flow monitoring on the PTN network:
the first step is as follows: creating a database of PTN network flow monitoring points, and storing and setting various monitoring point configuration information, wherein the configuration information comprises the following steps: the ID of the equipment where each monitoring point is located (if one equipment is provided with a plurality of monitoring points, the ID of the monitoring point can also be included); monitoring objects of various monitoring points; and specific monitoring parameters (such as monitoring period, monitoring mode, monitoring duration).
The second step is that: selecting a network QoS strategy, and selecting a target monitoring point according to the network QoS application strategy;
the network QoS policies may include two-tier network QoS policies and multi-tiered network QoS policies. The two-layer network QOS policy is for UNI ports and NNI ports in a PTN network. Multi-tiered network QOS policies are directed to UNI ports, transport channels (including PW and LSP), and NNI ports. Of course, it should be noted that network QoS policies may vary for different QoS application requirements.
And if the user sets a two-layer network QOS strategy, determining to monitor the flow aiming at the UNI port and the NNI port, and screening monitoring point information capable of monitoring the flow aiming at the UNI port and the NNI port from the database. During screening, corresponding target monitoring points can be searched for by using the UNI port and the NNI port as indexes, since the UNI port can be monitored on the first type monitoring point and the fifth type monitoring point, and the NNI port can be monitored on the second type monitoring point, the third type monitoring point and the fourth type monitoring point, screening results should be all monitoring points. If the two-layer network QOS strategy only requires to monitor each UNI port and the NNI port on the convergence layer, the first-type, the third-type and the fifth-type monitoring points can be obtained by screening again on the basis of the primary screening result; the information of the screening result may specifically be an ID of the target monitoring point and/or an ID of the device where the target monitoring point is located, and a monitoring parameter of the target monitoring point.
In practical application, for example, a monitoring object of the first type monitoring point and a monitoring object of the second type monitoring point have partially repeated appearance, or some monitoring points of the third type are arranged on an L2/L3 bridging device at the boundary of a core layer and a convergence layer, and the bridging device can also be provided with a B type monitoring point; for the above situation, the primary screening result (i.e. all monitoring points) of the two-layer network QOS policy can be screened again, at this time, the primary screening result may not be displayed to the user, and when the secondary screening is performed, the core layer device ID having the UNI port and NNI port attributes at the same time is screened out according to the monitoring point ID and/or the device ID and the monitoring parameters, i.e. the target monitoring point capable of monitoring the UNI port and the NNI port at the same time is screened out.
If a multi-level network QOS strategy is adopted, determining to monitor the flow of UNI ports, NNI ports and transmission channels (PW and LSP), screening all monitoring point information capable of monitoring the flow of UNI ports, NNI ports and transmission channels (PW and LSP) from a monitoring point database, and searching corresponding target monitoring points by using the UNI ports and the NNI ports as indexes during screening, because the first monitoring point and the fifth monitoring point can monitor the flow of the UNI ports, the second monitoring point, the third monitoring point and the fourth monitoring point can monitor the flow of the NNI ports, and the monitoring points capable of monitoring the flow of the NNI ports can also monitor the flow of the LSP and LSP, all monitoring points should be screened, the information of the screening result can be specifically the ID of the target monitoring point and/or the ID of the equipment where the target monitoring point is located and a target monitoring object, if monitoring parameters are preset, the information of the screening result may further include a monitoring parameter.
More specifically, since the second, third, and fourth monitoring points may monitor traffic of the NNI port and may also monitor LSP traffic of a transmission channel under a certain NNI port, when a user specifically selects or sets the monitoring points, the database may display the ID of the device where the second, third, and fourth monitoring points are located, the ID of the monitoring point, the identifier of the NNI port that can be monitored, the identifier of the LSP, and the identifier of the PW to the user, from which the user may select.
Of course, if the user selects or sets other network QOS policies, the target monitoring point and the target monitoring object can be determined according to the other network QOS policies.
The third step: after the target monitoring points and the target monitoring objects corresponding to the target monitoring points are screened out, the user can also specifically set the following configuration information according to the requirement: monitoring the reporting period of the result; monitoring the storage period and the storage format corresponding to the result, and the like.
The fourth step: after the configuration information of the target monitoring point is completely set, executing a flow monitoring task; the specific implementation process may be to count the number of packets to determine the corresponding flow rate through a counter on the monitoring point. In practical application, a counter may be set at a monitoring point, so that the counter may not only count the packet number of a UNI port or an NNI port, but also count the packet number of a certain PW under a certain LSP under a certain NNI port. In practical application, one monitoring point may also set multiple counters, each of which is only responsible for counting the number of messages in one layer, for example, some counters are only responsible for counting the number of messages in a port, some counters are only responsible for counting the number of messages in an LSP layer, some counters are only responsible for counting the number of messages in a PW layer, and if a user requires a certain device to start only a certain monitoring point and specifies that the monitoring point only monitors the traffic in a certain layer, only the counter responsible for monitoring the number of messages in the layer may be started. Similarly, if the specific time of the monitoring result is needed, one or more timers can be configured on the monitoring point.
The fifth step: comparing and analyzing the monitoring result with bandwidth attribute parameters (CIR and PIR) in the set QoS strategy, and planning according to the contents in the following table:
in conclusion, the method of the invention can flexibly and accurately monitor the flow of each link of the PTN network, thereby finely adjusting the bandwidth.
