Description

Capacity expansion planning method and capacity expansion planning system of internet data center

Technical Field

The invention relates to the technical field of internet, in particular to a capacity expansion planning method and a capacity expansion planning system for an internet data center.

Background

An existing Internet Data Center (IDC for short) machine room is mainly used for bearing servers or storages of various Internet services SP, and a terminal user accesses the servers or the storages in the IDC machine room through the Internet, so that most of flow of the IDC machine room is flow from the user terminal to the IDC machine room.

However, there is also traffic between IDC rooms. Because nodes of a Content Delivery Network (CDN) are usually deployed among IDC rooms, in the CDN, hot spot traffic is always pushed to the IDC room closest to a user as much as possible, a part of traffic of an equipment room is used to transmit the hot spot traffic, and traffic of the equipment room at the same time is also used to transmit some management data, such as charging information, monitoring information, and the like.

Traffic between IDC bays accounts for about 30% of the total traffic of an IDC bay, and this traffic has gained increasing attention in recent years because it is the basis for achieving good layout and management of a CDN network. Originally, the traffic can go to the internet (because the IDC rooms are on the internet), but considering the importance of the data, special networks need to be built for the traffic of the IDC rooms to carry the traffic.

With the popularization of the internet, the network traffic is rapidly expanded, and the computing resources of the IDC and the network nodes are often operated at full load, so that the existing IDC needs to be expanded to cope with the change of the network traffic.

When expanding the volume of the IDC, the IDC needs to be expanded and planned due to the limitation of manpower and material resources. Specifically, the sum of the total inflow traffic (including the inflow traffic flowing from the user side and the inflow traffic flowing from other IDC rooms) and the total outflow traffic (including the outflow traffic flowing to the user side and the outflow traffic flowing to other IDC rooms) of each IDC room is generally calculated to serve as the expansion priority index of each IDC room, then each IDC room is sorted according to the expansion priority index from large to small, and the sorted result serves as the final expansion construction sequence.

In actual operation, the existing capacity expansion planning method based on total flow statistics is relatively extensive and is difficult to meet the requirements of actual conditions; in addition, the existing capacity expansion planning method cannot perform capacity expansion planning on network construction between IDC machine rooms, so that the planning scheme is not comprehensive.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes in detail a capacity expansion planning method and a capacity expansion planning system of an internet data center provided by the present invention with reference to the accompanying drawings.

Fig. 1 is a flowchart of a capacity expansion planning method for an internet data center according to an embodiment of the present invention, and as shown in fig. 1, the capacity expansion planning method includes:

and step S1, calculating the total inter-room outflow flow and the total inter-room inflow flow corresponding to each IDC room according to the network flow when data transmission is carried out between each IDC room and other IDC rooms.

In the invention, the number of IDC machine rooms of the Internet data center is assumed to be n, wherein n is a positive integer. Before step S1, network traffic during data transmission between IDC rooms is collected in advance, where the network traffic flowing from the ith IDC room to the jth IDC room is recorded as Q_ijWherein, the value ranges of i and j are both [1, n]. After network traffic is collected when data transmission is performed between the IDC rooms, a corresponding network traffic list between the IDC rooms may be generated, as shown in table 1 below.

TABLE 1 network traffic List between IDC rooms

In step S1, based on the network traffic during data transmission between the IDC rooms, the total room outflow traffic and the total room inflow traffic of the IDC rooms can be obtained.

Optionally, step S1 includes:

step S101, network flow is normalized when data transmission is carried out between each IDC machine room and other IDC machine rooms.

Before the calculation, the entire network traffic may be normalized. For example, the maximum value in the network traffic list is selected, and quotient operation is performed on each value in the network traffic list and the maximum value, so that data in the network traffic list can be converted into a number between 0 and 1.

It should be noted that, in this embodiment, the calculation speed in the subsequent calculation process can be effectively increased by performing normalization processing on the network traffic when data is transmitted between each IDC room and other IDC rooms. It should be understood by those skilled in the art that the above-mentioned manner of performing quotient operation with the maximum value in the list to realize the normalization process is only an exemplary function, and other normalization algorithms can be used in the present invention to normalize the data in the list, and the details are not described in detail herein.

After the data in table 1 are normalized, table 2 can be obtained after the corresponding normalization process, as shown below.

TABLE 2 network traffic List after normalization

Step S102, calculating total inter-room outflow and total inter-room inflow corresponding to each IDC room based on the network flow after normalization processing;

wherein, in step S102, based on the formula:

$A_k=\underset{m=1}{\overset{n}{\Σ}}{P}_{km}$

$B_k=\underset{m=1}{\overset{n}{\Σ}}{P}_{mk}$

calculating the total outflow flow of the machine rooms and the total inflow flow of the machine rooms corresponding to the IDC machine rooms; wherein,A_ktotal outflow of machine room for the kth IDC machine room, B_kThe total inflow flow rate among machine rooms of the kth IDC machine room is that k takes a value range of [1, n]，P_kmIs the corresponding value P of the network flow from the kth IDC machine room to the mth IDC machine room after normalization processing_mkThe network flow from the mth IDC machine room to the kth IDC machine room is subjected to normalization processing to obtain a corresponding value.

The method is different from the prior art in that the network traffic between the user side and the IDC machine rooms is not collected any more, but only the network traffic between the IDC machine rooms in the Internet data center is collected, and the total inter-machine room outflow traffic and the total inter-machine room inflow traffic of the IDC machine rooms are obtained based on the collected network traffic between the IDC machine rooms.

And step S2, respectively calculating the capacity expansion priority indexes of the IDC rooms according to the total outflow flow rate of the rooms and the total inflow flow rate of the rooms corresponding to the IDC rooms.

In the invention, when the expansion priority index of each IDC machine room is calculated, only the network flow among the IDC machine rooms is considered independently, so that the IDC machine rooms can be positioned better. In addition, the machine room type corresponding to each IDC machine room can be judged in advance based on the total outflow and total inflow of the machine rooms between the IDC machine rooms, so that capacity expansion planning can be better performed.

Fig. 2 is a schematic diagram of the K-th IDC room mapped in the coordinate system, and as shown in fig. 2, the total outflow and total inflow of each IDC room and each IDC room can be respectively used as the abscissa and the ordinate to be mapped in the corresponding coordinate system. At this time, the value P after normalization processing_ijAre all less than 1, then A_kAnd B_kAnd is necessarily smaller than N, that is, the coordinates corresponding to each IDC engine room are necessarily located in four straight line limited areas Z, namely X is 0, Y is 0, X is N and Y is N.

In this case, the region Z can be divided into four regions Z on average using a straight line X ═ n/2 and a straight line Y ═ n/2₁、Z₂、Z₃、Z₄In which is located in the region Z₁The total outflow and inflow between the machine rooms of the IDC machine room are less, and the machine room belongs to an independent node machine room (the inflow and outflow of the flow are less); located in zone Z₂The total flow of the machine rooms of the IDC machine room is more, and the total flow of the machine rooms is less, so that the machine rooms belong to a central node machine room (the flow mainly flows to other machine rooms and is a main source of the flow); located in zone Z₃The total machine room outflow and total machine room inflow of the IDC machine room are more, and the machine room belongs to the machine room of the switching hub (the inflow and outflow of the flow are more); located in zone Z₄The total outflow of the machine rooms is more, and the total inflow of the machine rooms is less, so that the machine rooms belong to edge node machine rooms (the flows mainly flow into the machine rooms). In practical application, a central node machine room, a switching hub machine room and an edge node machine room are mainly used for capacity expansion.

Alternatively, in step S2, based on the formula:

$L_k=sin(\frac{\sqrt{2}\mathrm{\π}}{4n}*\sqrt{{\left(A_k\right)}^2+{\left(B_k\right)}^2})$

calculating the expansion priority index of each IDC machine room; wherein L is_kThe expansion priority index of the kth IDC machine room.

In this embodiment, the distance value from the coordinate of each IDC room to the origin (0, 0) is used as the priority parameter of each IDC room, and the priority parameter is normalized to obtain the expansion priority index corresponding to each IDC room. Specifically, in the coordinate system, the priority parameter (equal to the distance value from the corresponding coordinate to the origin) of each IDC machine room is less than or equal toThus, the formula:value of (A) is 0 or more and less than or equal toSo L_kThe value of (b) is 0 or more and 1 or less.

By the formula, the expansion priority index of each IDC machine room can be obtained, and the expansion priority index is limited in the range of 0-1, so that the data processing speed in the subsequent processing process can be increased.

It should be noted that the above equation is only a preferred embodiment in this embodiment to calculate the expansion priority index of each IDC room, and does not limit the technical solution of the present invention. Other algorithms can be adopted to calculate the expansion priority index of each IDC machine room, such as: the distance value from the coordinates of the IDC room to the origin is used as a priority parameter corresponding to the IDC room, or the average value of the total outflow and inflow of the IDC room is used as a corresponding expansion priority index, and specific algorithms are not illustrated one by one here. Those skilled in the art should know that all technical means for calculating the capacity expansion priority index based on the total outflow rate of the machine room of the IDC machine room and the total inflow rate of the machine room belong to the protection scope of the present invention.

And S3, sequencing the expansion priority indexes of the IDC rooms in a descending order to obtain the expansion order of the IDC rooms in the Internet data center.

In step S3, the expansion priority indexes of the IDC rooms calculated in step S2 are sorted in descending order, so as to obtain the expansion order of the IDC rooms in the internet data center.

The embodiment of the invention provides an expansion planning method for an internet data center, which is characterized in that the total inter-machine room outflow and the total inter-machine room inflow of each IDC machine room are obtained through the acquired network flow between the IDC machine rooms, and the expansion priority index of each IDC machine room is calculated based on the total inter-machine room outflow and the total inter-machine room inflow so as to obtain an IDC machine room expansion scheme which is more in line with the actual requirement.
