Background

With the rise and rapid development of home broadband and 5G services, traffic flow carried by network devices of a communication network is gradually increasing. In order to ensure normal use of the service, the communication operator needs to periodically expand the capacity of the network device, thereby increasing the processing capacity of the network device and reducing the load.

Therein, a network device of a communication network may comprise two levels: a convergence/access router layer and a core router layer. Wherein, the aggregation/access router layer and the core router layer comprise a plurality of routers. The plurality of routers may be used to forward data.

Detailed Description

Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application are explained:

the router: also referred to as gateway devices. A router is a hardware device that connects two or more networks and acts as a gateway between the networks. The router can read the network address in each data packet and forward the data packet according to the network address.

In network communication, a router has functions of judging a network address and selecting an IP path, and can construct a flexible link system in a plurality of network environments. The routers may link the various subnets through different data packets and media access patterns. The router can receive information transmitted by a source station or other relevant routers, and is an interconnection device based on a network layer.

An example is a communication network provided in the embodiments of the present application, as shown in fig. 1 and fig. 2. The communication network may include multiple tiers, and may include, for example, a lower network, an aggregation/access router layer, a core router layer, and an upper network.

The aggregation/access router layer and the core router layer may each include a plurality of routers, for example, the aggregation/access router layer may include aggregation/access routers 1 to 3, and the core router layer may include core routers 1 to 2.

Wherein, the lower links of a plurality of aggregation/access routers in the aggregation/access router layer are in communication connection with the equipment of the lower layer network. The upstream of the plurality of aggregation/access routers of the aggregation/access routing layer is connected to the plurality of core routers of the core routing layer. The upper connection of a plurality of core routers of the core routing layer is connected with equipment of an upper layer network.

The lower layer network may be a transmission network, and the device of the lower layer network may be an OLT device. The upper network may be a backbone network, and the devices in the upper network may be core network devices.

Wherein the core router may be connected to devices in the upper network via one or more routes. As shown in fig. 1, each core router is connected to devices in the upper network via a route, and this connection mode may be called a square-type uplink. As shown in fig. 2, each core router may be connected to a plurality of devices in an upper network through a plurality of routes, and this connection mode may be referred to as cross-type uplink.

It should be noted that, the capacity expansion manners of the core routers in different connection manners are different, and details will be described later, which are not described herein.

It should be noted that a router may be provided with a plurality of boards, each of which may have one or more ports. The port may act as an ingress or egress for data forwarding. Ports may be divided into a number of different levels depending on the capabilities. For example, the data can be classified into GE, 10GE, 100GE, etc., and the data amount carried by the ports of different levels is different. In this embodiment of the present application, expanding the capacity of the router may refer to increasing the number of boards of the router.

The board card of the router can be divided into a mother card and a daughter card. The mother card may be installed in a slot of the router. The mother card may have one or more ports (which may be referred to as a fixed board card) or may not have ports. In the case of a mother card without ports, a daughter card with ports (which may be referred to as a flexible card) needs to be mounted on the mother card.

At present, as the number of user terminals increases and the services of the user terminals increase, the amount of data carried by the router also increases. Therefore, to avoid data blocking, the communication carrier needs to expand the router.

In the prior art, the capacity expansion of the router is generally determined based on workers. However, the manual determination method has a certain limitation because the efficiency is low and the error is large.

In view of this, an embodiment of the present application provides a method for managing a route, where the method may include: the management device determines the bandwidth utilization rate and the port utilization rate of a target router, wherein the bandwidth utilization rate of the target router is determined according to the data flow rate and the bandwidth of the target router, and the port utilization rate of the target router is determined according to the ratio of the number of ports used by the target router to the number of configured ports; and under the condition that the bandwidth utilization rate and the port utilization rate of the target router meet preset capacity expansion conditions, the management device determines that the capacity of the target router is expanded.

Based on the technical scheme provided by the embodiment of the application, the management device can determine whether to perform capacity expansion on the router according to the bandwidth utilization rate and the port utilization rate of the router. Because the bandwidth utilization rate and the port utilization rate of the router can reflect the load condition of the router, the load of the router is higher when the bandwidth utilization rate and the port utilization rate of the router meet the preset capacity expansion condition. Under the condition that the load of the router is high, the management device can determine to expand the capacity of the router, and compared with a method based on manual judgment in the prior art, the technical scheme provided by the application is more accurate and flexible.

Fig. 5 provides a management method for a router according to an embodiment of the present application, and as shown in fig. 5, the method includes:

step 501, the management device determines the bandwidth utilization and port utilization of the target router.

Among them, the management device may be the management device in fig. 3, and the management device may have the components of fig. 4. The destination router may be the router in fig. 1 or fig. 2. For example, it may be a core router or an aggregation/access router in fig. 1 or fig. 2.

The bandwidth utilization of the target router may refer to an uplink bandwidth utilization of the target router. The uplink bandwidth utilization of the target router may be a ratio between a data rate of the uplink direction route of the target router and a bandwidth configured by the uplink route.

For example, when the target router is a core router, the data rate in the upstream direction of the core router may refer to the data rate flowing from the core router to the upper network. For example, the ratio of the total amount of data flowing from the uplink port of the core router to the upper network within the preset time period to the preset time may be used. The preset time may be set according to needs, and for example, may be 24 hours, one week, or one month, without limitation. The data rate in the uplink direction of the core router may also be the maximum traffic rate flowing from the uplink port of the core router to the upper network within a preset time period.

For another example, when the target router is a convergence/access router, the data rate in the upstream direction of the convergence/access router may refer to the data rate flowing from the convergence/access router to the core router. For example, the ratio of the total amount of data flowing from the uplink port of the aggregation/access router to the core router within the preset time period to the time before the preset time may be used. The preset time can be referred to above and will not be described again. The data rate in the uplink direction of the aggregation/access router may also be the maximum traffic rate flowing from the uplink port of the aggregation/access router to the core router within a preset time period.

The port utilization of the target router may be determined according to the used port and the configured port of the target router. Specifically, the management device may determine the port utilization of the target router according to the port type and number used by the target router and the configured port type and number.

In one example, the management device may determine the port utilization of the target router according to formula one.

R＝∑(U _i *A _i )/∑(M _j *A _j ) Formula one

Where R represents the port utilization of the target router. U shape _i Indicating the number of ports used by the target router, A _i Indicating the capabilities of the port used by the target router. M is a group of _j Number of ports, A, representing configuration of target router _j Indicating the capabilities of the port configured by the target router.

For example, the target router is configured with both 10GE and 100GE types of ports. The number of 10GE ports is 20, and the number of 100GE ports is 5. The number of 10GE ports used by the target router is 8, and the number of 100GE ports used is 3, then the port utilization rate of the target router may be (8 × 10+3 × 100)/(20 × 10+ 5) ≈ 54.3.

Step 502, when the bandwidth utilization rate and the port utilization rate of the target router meet the preset expansion condition, the management device determines to perform expansion for the target router.

The preset capacity expansion condition may be used to determine whether capacity expansion is performed for the target router. For example, the preset capacity expansion condition may include a plurality of thresholds, and the plurality of thresholds may be used to limit the bandwidth utilization of the target router and the upper limit of the port utilization. That is, when the bandwidth utilization of the target router is greater than the first threshold and the port utilization is greater than the second threshold, the management apparatus may determine that the capacity of the target router is expanded. The first threshold and the second threshold may be set as needed or determined according to historical data, and are not limited.

In one example, the management apparatus may determine the first threshold and the second threshold from historical data. The historical data may refer to historical data of routers in the communication system. For example, the historical data may include Identification (ID) of the router, time, data traffic, port, etc. data. The following describes a method for determining the first threshold and the second threshold:

1. a method of determining the first threshold.

S1, the management device determines a data traffic growth coefficient of each router in a plurality of routers.

The data traffic growth coefficient of the router is determined according to the ratio of the data traffic rate of the first time period to the data traffic rate of the second time period.

The first time period is a time period which is after and adjacent to the second time period. The time lengths of the first time period and the second time period are the same, and the time lengths may be set according to needs, for example, 10 days, 30 days, and the like, without limitation.

The data traffic rate of the first time period may refer to an average data traffic rate of the router in the first time period, or a maximum data traffic rate in the first time period. The data traffic rate for the second time period may be an average data traffic rate of the router over the second time period.

It should be noted that, in the embodiment of the present application, data rates of consecutive multiple time periods may be obtained, and multiple data traffic growth coefficients may be determined according to the data rate of an adjacent time period in the data rates of multiple time periods.

And S2, the management device determines a first threshold value according to the data traffic increase coefficients of the routers.

The data traffic increase coefficient of the plurality of routers may refer to a maximum data traffic increase coefficient of the plurality of routers. The first threshold may be determined based on a maximum of maximum data traffic growth coefficients for the plurality of routers,

for example, the maximum data traffic growth factor of the router 1 is α ₁ The maximum data traffic growth coefficient of the router 2 is α ₂ The maximum data traffic growth coefficient of the router 3 is α ₃ . The first threshold =1/max (α) ₁ ，α ₂ ，α ₃ )。

Of course, the first threshold may also be an average value, a weighted average value, an intermediate value, or the like of the maximum data traffic growth coefficients of the plurality of routers, which is not limited.

2. And determining a second threshold value.

And S3, the management device acquires the number of the used ports in a plurality of continuous time periods of each router.

And S4, the management device determines the port growth coefficient of the router according to the number of the ports used by the router in a plurality of continuous time periods.

The port growth coefficient of the router is the ratio of the number of the ports used in the first time period to the number of the ports used in the second time period. The first time period is a time period after and adjacent to the second time period. In this manner, the management device may determine a plurality of port growth factors for each router.

And S5, the management device determines a second threshold value according to the maximum port growth coefficient of the plurality of routers.

Wherein, the maximum port growth coefficient of the router refers to the maximum value of the plurality of port growth coefficients of the router. The second threshold may be determined for a maximum value of a maximum port growth factor of the plurality of routers.

For example, the maximum port growth factor of the router 1 is β ₁ The maximum port growth factor of the router 2 is β ₂ The maximum port growth coefficient of the router 3 is β ₃ . Then, the second threshold =1/max (β) ₁ ，β ₂ ，β ₃ )。

It should be noted that in the solution of fig. 5, the target router is of the same type as the above-mentioned routers. For example, if the target router is a core router, the plurality of routers are also core routers; if the target router is a convergence/access router, the plurality of routers are convergence/access routers.

Based on the technical scheme in fig. 5, the management apparatus may determine whether to perform capacity expansion for the router according to the bandwidth utilization rate and the port utilization rate of the router. Because the bandwidth utilization rate and the port utilization rate of the router can reflect the load condition of the router, the load of the router is higher when the bandwidth utilization rate and the port utilization rate of the router meet the preset capacity expansion condition. Under the condition that the load of the router is high, the management device can determine to expand the capacity of the router, and compared with a method based on manual judgment in the prior art, the technical scheme provided by the application is more accurate and flexible.

In a possible implementation manner of the method shown in fig. 5, after determining to perform capacity expansion for the target router, the method provided in this embodiment of the present application may further include: the management device determines first board card information from a preset board card recommendation library according to a preset capacity expansion strategy.

The first board information may at least include a board model, a type, and a number.

The preset capacity expansion strategy can be used for determining the capacity expansion or increased board card information of the target router. Specifically, it will be described later.

The preset board information base can be used for providing usable boards for the management device when the capacity of the target router is expanded. The preset board recommendation library may be configured for the management device, or may be generated by the management device, which is not limited. For example, the preset board recommendation library may be stored in the management device in a table format, or may be stored in an array format, without limitation.

In one example, the preset board recommendation library may include a plurality of routers and configuration information of each router in the plurality of routers. The configuration information may include an ID of the router, a model of the router, capability and manufacturer information of the router, types of boards configured by the router, the number and types of ports of the boards, capability of the boards, and the like. The board information in the preset board recommendation library can be determined according to the board information in a working state in the current network.

In a possible implementation manner, the management device may determine a preset board recommendation library according to the association relationship between the router and the boards and the scores of the boards of the various models.

In one example, the association relationship between a router and a board card it has may be as shown in table 1.

TABLE 1

/>

It should be noted that the data in table 1 is only exemplary, and may include other data, without limitation. The cards in table 1 may be daughter cards or mother cards of an existing network. The router and the mother card are in one-to-many relationship, and the mother card and the daughter card are in one-to-many relationship. The board card can be a board card for actually processing services, and comprises a fixed board card and a flexible board card.

It should be noted that the data in table 1 is only used to describe the configuration board and port of one router. In the embodiment of the application, the management device can determine the board card and the port information configured by each router in the current network. Further, the management device can classify the association relationship between the plurality of routers and the board card according to the home machine room of the router. Thus, management can be facilitated.

Further, in order to select boards more accurately, the management device may determine scores of boards of various models based on the information in table 1. The score of the board card can reflect the use priority of the board card. That is, the higher the score of the board card is, the higher the management device can preferentially configure the board card for the target router.

For example, the management device may determine the score of the board according to the multiple dimensions and the corresponding weights. The plurality of dimensions may include: the latest network access year of each type of board card (daughter card and mother card), the board card density (the number of ports on one board card), the board card type ratio, the board card type and the online proportion of the ports on the board card. The weight of each dimension may be set as required, for example, the corresponding weight may be determined according to the importance degree of each dimension.

In one example, the scores and weights for each model of board may be as shown in Table 2.

TABLE 2

The values in table 2 may be set as needed, and are not limited. For example, the latest network access year of the board card may be divided in units of months. For another example, the values corresponding to the card type ratios in the same year and the online port ratios may be set as needed, for example, x may be 40%, y may be 30%, and n may be 20% in table 1, which is not limited. For example, the score and the weight of the board card may be set as required, which is not described in detail.

Further, the score for each type of board may be determined based on one or more of the following strategies.

The more recent the strategy 1 and the network access year of the board card, the board card is used latest and has high priority.

And 2, in the strategy, because the number of the slots of the router is limited, the board card with high board card density is preferentially selected within the capacity range of the router. The board density refers to the number of ports of the board.

It should be noted that, because the capability of the router is limited, if the sum of the capabilities of the boards configured by the router exceeds the processing capability of the router, the boards are wasted. Therefore, the sum of the processing capacity of the newly added board card of the router and the processing capacity of the existing board card of the router does not exceed the processing capacity of the router. The processing power of a router may refer to the total amount of data that the router is able to forward per unit time.

And 3, selecting a board card with installation time not exceeding a preset year (such as three years). If the number of the type of the board card is larger, it indicates that the use priority of the type of the board card is higher.

And 4, selecting a board with high evolution technology, for example, selecting a flexible daughter card.

And 5, selecting a board card with a high online port ratio. If the proportion of the online ports of the board card is low, the board card is poor in use tendency or prone to failure, and the purchase priority is low. Therefore, the management device can preferentially select the board with the online port larger than the preset ratio. The preset ratio can be set according to the requirement, for example, can be 60% or 80%, and is not limited.

It should be noted that the above strategies 1 to 5 are only exemplary, and other strategies may be provided, for example, selecting a board with a relatively high cost performance, selecting a board with a simple mounting process, and the like, without limitation.

Further, based on the association relationship between the routers and the board cards in table 1 and the scores of the board cards of the types in table 2, the management device may group the routers and the board cards according to manufacturers, the capability of the target router, and the capability of the board card bearing port, select the type of the daughter card or the mother card with the highest score in each group, and establish a preset board card recommendation library.

In an example, the preset board recommendation library may include a plurality of routers and configured board information, and each router and configured board information may be as shown in table 3.

TABLE 3

It should be noted that the ID in table 3 can be used to uniquely identify a router and its board information. That is, the router and its board information in table 3 is a router and its board information in the preset board recommendation library. The router and the board card information thereof may be the router and the board card information thereof with the score determined according to the rule of table 2 larger than the preset score, or the router and the board card information thereof determined according to other rules.

Table 3, the mother card including a slot without a port may mean that the mother card does not have a port, but has a slot for mounting a daughter card. The board capability may refer to the number and type of ports the board has. For example, a card capability of 10GE indicates that the card has 10GE ports. For another example, a card capability of 5 × 10GE indicates that the card has 5 ports of 10GE.

In one example, based on table 3, the information in table 3 is: hua is-400 GE-3- (P240-A) -10GE-10. That is, the board information is: the router manufacturer belongs to Huawei, the router capacity is 400GE, the board type is daughter card, the board type is P240-A, the board has a port type of 10GE, and the board capacity is 10 × 10GE (namely, 10GE ports are provided).

In a possible implementation manner, after determining the board card information configured for the target router, the management device may select different expansion schemes to configure the board card for the target router according to the type of the target router and the router and board card information thereof in table 3.

Wherein, if the target router is a convergence/access router, the management device can select a first scheme; if the target router is a core router, the management apparatus may select scheme two. Scheme one and scheme two are described below.

In the first aspect, if the target router is a convergence/access router, the management apparatus may execute the following A1 to A7.

It should be noted that, according to the operation and maintenance requirements of communication, the links of the aggregation/access router device cannot be bundled, that is, the port types of all uplink links of the aggregation/access router need to be consistent. Therefore, the management device may use the port type of the currently existing uplink of the aggregation/access router as the port type that needs to be expanded.

A1, the management device can obtain card information capable of expanding capacity from a preset card recommendation library according to the capacity of the target router, a manufacturer and the type of a port needing expansion.

Because the port may be carried by the daughter card or directly by the mother card, the expandable board card may include the daughter card and the mother card, or may be the mother card directly carrying the port.

A2, if the expandable board card is a mother card, expanding the mother card; if the expandable board card is the daughter card and the mother card, after expanding the daughter card, the management device may determine whether the mother card needs to be expanded according to whether the target router has an empty Yu Zi slot.

In an example, if the management device determines that the card type that the target router can expand is a daughter card, the management device determines that the expansion scheme may include the daughter card when the target router has an empty Yu Zi slot; and under the condition that the target router does not have the spare sub slot position, the management device determines that the capacity expansion scheme can comprise the daughter card and the mother card.

And A3, the management device determines the quantity of the expanded board cards according to the disaster tolerance requirement of the target router.

The disaster recovery requirement may refer to whether the capacity-expanded port of the router needs a port for backup of the device, and the backup port and the capacity-expanded port are not located on the same board card.

Specifically, if the target router does not have the disaster tolerance requirement, the management device may determine the number of boards increased at one time as the number of boards required for capacity expansion of the target router; if the target router has a disaster tolerance requirement, the management device may determine that the number of boards that are increased at least once is twice the number required for capacity expansion.

For example, if the number of boards that need to be expanded is 1, that is, the number and the type of the ports of the board can meet the expansion requirement of the target router. In a case where the target router has a disaster tolerance requirement (the aggregation/access router generally has a disaster tolerance requirement), the management device may determine that the number of boards expanded by the target router is 2.

And A4, after determining that the card information is the card information of the target router, the management device can judge whether the bandwidth utilization rate and the port utilization rate of the target router meet the preset capacity expansion condition again. And if so, continuing to expand the capacity board card until the bandwidth utilization rate and the port utilization rate of the target router do not meet the preset capacity expansion condition.

The bandwidth utilization rate and the port utilization rate of the target router can be determined according to the existing board card information and the board card information after capacity expansion. That is, the management device may also use the expanded board information as the board information used by the target router, and then the management device may calculate the bandwidth utilization rate and the port utilization rate of the target router according to the existing board information and the expanded board information. The method for calculating the bandwidth utilization and the port utilization may refer to the above description, and is not repeated herein.

In an example, taking 70% as the first threshold of the target router as an example, the bandwidth of the target router in the existing uplink direction is 8 × 100ge, and the data rate is 700GE, that is, the uplink bandwidth utilization rate of the target router before capacity expansion is 700/800=87.5%. If the management device determines that the board information expanded by the target router includes 1 board with 1 × 100ge according to the above technical scheme, at this time, the management device may determine that the utilization rate of the uplink bandwidth of the expanded target router is 700/(800 + 100) ≈ 77.8% > 70%. That is, the management device needs to continue to expand the target router, for example, add another 1 × 100ge board card. At this time, the management device may determine that the uplink bandwidth utilization of the re-expanded target router is: 700/1000=70%. That is, the uplink bandwidth utilization rate of the target router expanded again does not satisfy the preset expansion condition, and the board card information determined by the management device to be expanded by the target router may include 2 boards 1 × 100ge.

For another example, when the second threshold of the target router is 70%, the number of existing ports of the target router is 60, and 50 ports are used. That is, the port utilization of the target router before capacity expansion is 50/60 ≈ 83% > 70%. If the management device determines that the board card information expanded by the target router includes 1 10 × 10ge board card according to the above technical solution, at this time, the management device may determine that the port utilization rate of the target router after the target router is expanded is 50/70 ≈ 71.4% and is greater than 70%. That is, the management device needs to continue to expand the target router, for example, add another 1 by 10ge board. At this time, the management apparatus may determine that the port utilization of the re-expanded target router is 50/80=62.5% < 70%. That is, the port utilization of the target router which is expanded again does not satisfy the preset expansion condition, and the management device determines that the expanded board information of the target router may include 2 10 × 10ge.

Further, with reference to the above two examples, in order to ensure that both the uplink port utilization rate and the port utilization rate of the target router do not satisfy the preset capacity expansion condition, the management device may determine that the board card information expanded by the target router may be 2 board cards of 10 × 10ge and 2 board cards of 1 × 100ge. At this time, the expanded board card information can meet the expansion requirement of the target router.

Or under the condition that the availability of the uplink bandwidth of the expanded target router does not meet the preset expansion condition, continuing to expand the capacity of the target router based on the expanded target router until the availability of the port of the expanded target router does not meet the preset expansion condition.

Or, under the condition that it is determined that the port utilization rate of the expanded target router does not satisfy the preset expansion condition, continuing to expand the capacity of the target router based on the expanded target router until the uplink bandwidth utilization rate of the expanded target router does not satisfy the preset expansion condition.

And A5, the management device outputs the capacity expansion scheme.

The capacity expansion scheme may include information such as the type, and number of the board cards.

And A6, the management device calculates the number of ports, which are required to be expanded, of the target router, wherein the bandwidth utilization rate of the target router is less than a first threshold value and the port utilization rate of the target router is less than a second threshold value, and the number of the ports is an integral multiple of 2 (as shown in figure 1, the aggregation/access router is connected with a pair of core routers in an upper connection mode, so that the number of the ports, which are required to be expanded, of the core routers connected with the aggregation/access router in the upper connection mode is an integral multiple of 2), and the number and the type of the expanded ports of the aggregation/access router are added into the capacity expansion requirement of a pair of core routers connected with the aggregation/access router in a lower connection mode.

And A7, repeating the above processes until the management device generates a capacity expansion scheme for the aggregation/access router of which the bandwidth utilization rate and the port utilization rate in the management range meet the preset capacity expansion conditions.

It should be noted that, for a plurality of aggregation/access routers within the management range, if there is an uplink bandwidth utilization rate and a port utilization rate of at least one aggregation/access router in the plurality of aggregation/access routers that satisfy the preset capacity expansion condition, but the overall uplink bandwidth utilization rate and the port utilization rate of the plurality of aggregation/access routers do not satisfy the preset capacity expansion condition, the management device determines that capacity expansion may not be performed for the at least one aggregation/access router.

The overall uplink bandwidth utilization of the aggregation/access routers may refer to an average of the uplink bandwidth utilization of the aggregation/access routers, or may refer to the uplink bandwidth routing rate of the aggregation/access routers calculated according to a sum of the uplink bandwidth of the aggregation/access routers and a sum of the uplink bandwidth rates of the uplink bandwidth of the aggregation/access routers.

The total port utilization of the aggregation/access routers may be an average of the port utilization of the aggregation/access routers, or may also be determined according to all the port types and the total number used by the aggregation/access routers and the port types and the number configured by the aggregation/access routers.

In the second aspect, if the target router is a core router, the management apparatus may execute the following B1 to B9:

it should be noted that, since the core router capacity expansion includes the capacity expansion requirement of the lower link caused by the uplink connection of the aggregation/access router and the capacity expansion requirement of the upper link when the bandwidth utilization rate of the uplink connection of the core router and the port utilization rate meet the preset capacity expansion condition, the core router capacity expansion scheme may include: the method and the system meet the requirement of the core router for the downlink and meet the board card information corresponding to the requirement of the core router for the uplink. Specifically, reference may be made to the following description of the method.

B1, the management device determines the downstream capacity expansion requirement of the core router corresponding to the plurality of aggregation/access routers according to the upstream capacity expansion requirement of the plurality of aggregation/access routers.

The method for determining the uplink capacity expansion requirement of the aggregation/access router may refer to the description of the first aspect. The core router corresponding to the plurality of aggregation/access routers may refer to a core router that is connected to the plurality of aggregation/access routers. For example, in fig. 1, the core routers connected to the aggregation/access routers 1 to 3 are a core router 1 and a core router 2.

Taking the core router 1 as an example, the downlink requirement of the core router 1 may be the uplink capacity expansion requirement synthesis of the aggregation/access router 1, the aggregation/access router 2, and the aggregation/access router 3. For example, the upstream capacity expansion requirement of the aggregation/access router 1 is 2 × GE (i.e., 2 GE ports), the upstream capacity expansion requirement of the aggregation/access router 2 is 4 × 10GE (i.e., 4 10GE ports), the aggregation/access router, and the upstream capacity expansion requirement of the aggregation/access router 3 is 4 × GE (i.e., 4 GE ports). The downstream capacity expansion requirement of the core router 1 may include: 6 × ge and 4 × 10ge.

And B2, the management device expands the capacity of the downlink port of the core router according to the downlink capacity expansion requirement of the core router.

Specifically, the management apparatus may refer to the following B21 to B25 for expanding the downstream port of the core router:

and B21, the management device judges whether the number of ports which are in an idle state and have the same type as the capacity expansion ports of the core router meets the downstream capacity expansion requirement of the core router or not. If the port utilization rate is met, the management device takes the port which meets the downstream capacity expansion requirement of the core router and is in the idle device as the port in the use state, and calculates the port utilization rate of the core router according to the port in the use state and the total number of the ports of the core router. If the port utilization rate of the core router does not exceed the second threshold, the capacity of the core router is not expanded; if the port utilization rate of the core router exceeds the second threshold, the core router is expanded, and the management device executes the following steps B22 to B24.

For example, taking the downstream demand of the core router including 6 × GE and 4 × 10GE as an example, the management device may first determine whether a GE port in an idle state of the core router satisfies a capacity expansion demand, and after taking the GE port in the idle state as a used port, whether the port utilization rate of the core router exceeds a second threshold. If not, not expanding the GE port of the core router; and if so, expanding the GE port of the core router.

It should be noted that, expanding the core router may refer to adding boards of the core router, and the port types of the added boards are the same as the port types of the core router. In addition, the number of the ports of the core router after the board card is added can meet the capacity expansion requirement of the core router, and the utilization rate of the ports does not exceed the second threshold value.

And B22, the management device acquires the expandable board card information from a preset board card library according to the capacity of the core router, the manufacturer and the type of the expansion port.

The card information that can be expanded may include a daughter card + a mother card or only a mother card, and the port type of the daughter card or the mother card is the port type required by the core router.

And B23, the management device determines the number of the expanded board cards according to the disaster tolerance requirement of the target router.

It should be noted that, according to the operation and maintenance requirements of the communication operator, the core router does not involve a disaster tolerance problem, and therefore, the management device may configure the board card for the core router according to the requirements of the core router.

And B24, the management device determines the port number of each type required by the core router according to the B21 and the B23 until the type and the number of the expanded ports meet the downlink requirement of the core router.

For example, the downstream requirements of a core router include GE ports and 10GE ports. After determining the board card information corresponding to the GE port of the core router, the management device may determine the board card information corresponding to the 10GE port of the core router. Thus, the management device can determine the board information corresponding to each port type of the core router.

And B3, after the board card corresponding to the downlink port is expanded, the management device calculates the uplink bandwidth utilization rate and the port utilization rate of the core router.

The port number of the core router includes the number of the expanded ports (i.e., the ports of the expanded board card).

And B4, the management device determines the uplink capacity expansion requirement of the core router according to the uplink bandwidth utilization rate and the port utilization rate of the core router.

It should be noted that, since all the core routers in the existing network have a standby core router, and the configuration of the standby core router matches the configuration of the core router, when the management apparatus expands the core router, it is necessary to determine the standby core router of the core router. For example, the management apparatus may determine a standby core router of the core router according to the identifier and the corresponding relationship of the core router. The management device may pre-store a correspondence between the core router and the standby core router, and may also obtain the correspondence from other devices without limitation. Therefore, after determining the capacity expansion scheme of the core router, the management device may further perform capacity expansion for the standby core router according to the capacity expansion scheme.

The core router and the backup router may be referred to as B5 to B11 below.

And B5, the management device acquires the uplink port type of the core router.

The management device may traverse all ports of the core router, and determine the uplink port of the core router according to the opposite terminal device type of the port.

Specifically, as shown in fig. 1 and fig. 2, the opposite end device of the uplink port of the core router is an upper network device, and the opposite end device of the downlink port is an aggregation/access router. Therefore, the management can determine whether the port is an uplink port or a downlink port according to the opposite terminal device type of the port of the core router.

And B6, the management device selects card information capable of expanding capacity from a preset card recommendation library according to the capacity of the core router, the manufacturer and the type of the expansion port.

This step can be referred to as B22, and is not described in detail.

And B7, the management device determines a corresponding capacity expansion scheme according to the connection mode of the core router and the upper network.

As can be seen from fig. 1 and 2, the connection between the core router and the upper network includes a square upper connection and a cross upper connection.

When the connection mode of the core router and the upper network is square upper connection, the management device only needs to determine the number of ports needing capacity expansion according to the capacity expansion requirement of the upper connection of the core router; when the connection method of the core router and the upper network is cross-connection, the number of the ports of the management device which need to be expanded is 2 times of the expansion requirement of the upper network.

For example, when the uplink requirement of the core router is 1 port, the management device determines that the number of ports of the core router, which need to be expanded, is 1 when the connection mode of the core router and the upper network is square uplink; when the connection method of the core router and the upper network is cross-connection, the management device determines that the number of the ports of the core router, which need to be expanded, is 2. Based on this, the management device can determine different capacity expansion schemes according to different modes of the core router and the uplink network, and is flexible and accurate.

It should be noted that, if the expanded board card information includes the daughter card and the mother card, the management device needs to determine whether the core router has an available slot. If not, adding the mother card and the daughter card; if so, only daughter cards may be added.

And B8, the management device outputs the capacity expansion scheme.

And B9, the management device repeats the steps and determines the port utilization rate in the management range and the capacity expansion scheme of the core router of which the port utilization rate meets the preset capacity expansion condition.
