Description

Method for displaying service flow statistics of all links on the network

technical field

The present invention relates to a network management technology, more specifically to a method for displaying the statistics of all link service flows (or service resource usage) on the network. Business traffic, or the usage of business resources, in order to classify, retrieve or perform other activities on the use of business resources,

Background technique

In the service transmission network, including but not limited to: Asynchronous Transfer Mode (ATM), IP, Synchronous Digital Hierarchy (SDH) and Wavelength Division Multiplexing (DWDM) networks, it is generally required to display the information on the network dynamically or statically on the network management system. The service flow of each link, or the use of service resources, so that the network management operator can intuitively understand the service configuration distribution of the entire network and the load of network resources, so as to meet the requirements of network service increase, service adjustment, and network expansion .

The current practice is: on the network topology diagram composed of network element nodes and interconnecting links (data transmission paths), the calculated statistics of the percentage of business resources already occupied by each link are directly displayed on the network topology Figure on the corresponding link. As shown in Figure 1, the network element nodes NE1, NE2, NE3, NE4, NE5, and NE6, and the interconnection links between the network element nodes indicate the percentage data of the service resources already occupied between the two nodes, as shown in the figure 20%, 92%, 65%, 80%, 33%, and 50% are shown in . The percentage data shown in the figure is the percentage data of the already occupied bidirectional service resource of the link between the two network element nodes, or two data can be used to represent the percentage already occupied of the unidirectional service resource of the two directions respectively.

This way of displaying the usage of network link resources is acceptable when the network is relatively simple and the number of network element nodes and links is relatively small. However, when the network scale is relatively large, the networking is relatively complex, there are multiple links between two network element nodes, or the link display length in the topology diagram is short, all data will be displayed in the entire network topology diagram It will be very messy, and the operator cannot accurately browse and judge the service flow on the corresponding network link.

If it is required to simultaneously display the unidirectional resource usage of links in the topology diagram, more data needs to be displayed, which is even more chaotic and difficult to identify clearly. However, in practical applications, two unidirectional resource usage data generally need to be displayed on a link in the network topology diagram (directions are just opposite on the link). For example, on the link between NE4 and NE5 in Figure 1, the unidirectional service from NE4 to NE5 only occupies the link service resources from NE4 to NE5, and the unidirectional service from NE5 to NE4 only occupies the resources from NE5 to NE4. link service resources. Generally, these two data are different, so they both need to be displayed, but according to the above data display method, there will be more data displayed on the network topology map, and it is difficult to distinguish between the data due to the area limitation.

Contents of the invention

The purpose of the present invention is to design a display method for all link service flow statistics on the network, which is used to solve the display problem of link resource usage on the network topology map, so that large-scale and complex networks, and large-scale service flow statistics On the network topology map of the data, the service flow of all links (transmission paths) on the network or the usage of service resources can also be visually displayed.

The technical solution for realizing the object of the present invention is as follows: a method for displaying service flow statistics of all links on the network, on a network topology diagram composed of network element nodes and their interconnected links, two network elements are displayed The usage of service resources counted on the links between nodes is characterized by including:

Divide the link graph into two connected first and second parts; calculate the coordinates of the division point of the two-part link graphic interface on the network topology map, which is ((x2-x1)×r+x1, (y2- y1)×r+y1), wherein (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the link graph on the network topology map, and r is the total service resource rate occupied by the link service flow of statistics; Displaying the link graphics of the first part and the link graphics of the second part, the ratio of the length of the first part of the link graphics to the total length of the link graphics is the ratio of the service resources already occupied on the link to the The ratio of the total service resources of the link and the ratio of the length of the second part of the link graph to the total length of the link graph are the ratios of the idle service resources on the link to the total service resources of the link.

It also includes the coordinates of the two-part link graphical interface division point on the network topology map as ((x2+a-x1+a)×r1+x1+a, (y2+a-y1+a)×r1+y1+a ), where (x1+a, y1+a) and (x2+a, y2+a) are located near the coordinates (x1, y1) and (x2, y2) of the two endpoints of the link graph on the network topology map The coordinates of the two endpoints on the network topology map, r1 is the total service resource rate occupied by the single-service traffic in one direction of the statistical link; ((x2-a-x1-a)×r2+x1-a, (y2-a-y1-a)×r2+y1-a), where (x1-a, y1-a) and (x2-a, y2-a) is the coordinates of the other two endpoints near the coordinates (x1, y1) and (x2, y2) of the two endpoints of the link graph on the network topology diagram, and r2 is the statistical link The single service flow in the other direction occupies the total service resource rate, and a is the width used to describe the link graph in the network topology diagram.

The present invention displays the use of network service resources based on the existing network topology diagram on the network management system, and according to the characteristics of link display in the network topology diagram, directly displays the corresponding links directly on the basis of the links in the network topology diagram in the form of different color graphics. Service resource usage of the road.

In the network management, the links on the network topology map already exist. The method of the present invention is based on the display of the original links, and displays the use of link resources in graphics of different colors without additional symbols or texts.

Description of drawings

FIG. 1 is a schematic diagram of a data display mode used by bidirectional service resources of a network link;

FIG. 2 is a schematic diagram 1 of a graphic display mode for use of network link bidirectional service resources;

FIG. 3 is a schematic diagram 2 of a graphic display mode of network link unidirectional service resource usage.

Detailed ways

Referring to FIG. 2 , it shows that on the network topology diagram of the network management system, the method of the present invention is used to display the usage of service resources on any link, including the display of unidirectional and bidirectional resource usage.

On each link on the network topology map, the link graph in the first color (such as red, represented by a solid line segment, the same below), indicates the use of service resources on this link, and the second color (such as green, represented by a hollow line segment, the same below) the link graph indicates the situation that the service resources on this link are idle. According to the length of the link, the proportion of the part painted in the first color (such as red) on the link graph is exactly the ratio of the service resources already occupied on the link to the total service resources of the link; The proportion of the part painted in the second color (such as green) on the graph is just the ratio of the idle service resources on the link to the total service resources of the link.

The technical solution to achieve the corresponding display effect is: on the graphical interface of the network topology map, the link is generally represented by a graph formed by a straight line of a certain width connecting the nodes at both ends, so the two links are set to A1 and A2 The coordinates of the endpoints on the graphical interface can be set to A1 (x1, y1) and A2 (x2, y2) respectively, and the total service resource rate occupied by the service traffic of this link has been calculated and counted by the network management, which is set to r. In order to obtain an intuitive display effect of link traffic resource occupation, it is necessary to redraw the link twice on the interface, and calculate the coordinates of the middle division point M of the two color graphics: M((x2-x1)×r+ x1, (y2-y1)×r+y1), then you can use the first color (such as red) to draw the link from A1 to point M, and then use the second color (such as green) to draw the link from M to A2 Link graphics. In this way, the proportion of service resources occupied by service traffic on the link is directly and visually displayed on the link.

For the display of link bidirectional service resources, use two colors to display the usage status and idle status of the bidirectional service service resources on a link graph between two nodes. In the figure, the links between nodes NE3, NE4, NE5, NE6, NE7, and NE8 and the links between nodes NE9, NE10, NE11, NE12, NE13, and NE14 are shown.

For the display of unidirectional service resources on a link, the usage and idleness of service resources in two directions on the link are displayed on the two links between two nodes in two colors, respectively, as shown in the figure Among them, the link between node NE1 and node NE2, the link between node NE2 and node NE2-1, the link between node NE2 and node NE2-2, the link between node NE1 and node NE1-1, the link between node NE1 Links to nodes NE1-2. After displaying by the method of the present invention, four usage situations of link resources can be shown: usage of business resources in the direction from node A to node B, idleness of business resources, and usage of business resources in the direction from node B to node A. Usage status, business resource idle status.

Referring to FIG. 3 , all shown in the figure are the display of link unidirectional service resources. On each link on the network topology diagram, the one-way service resource display method of the link from the source network element node to the sink network element node is further shown, and the first color (such as red) part indicates that the service resource is The usage status is close to the source network element node end, and the second color (such as green) part indicates the service resource idle condition, and is close to the sink network element node end.

The realization scheme of the corresponding display effect: on the graphical interface of the network topology map, the realization of the resource occupancy rate display of the one-way service on the link is roughly the same as that of the two-way service, but because two of them need to be displayed, the difference in the corresponding processing is: Let the endpoints of a link be A1 and A2, and the corresponding coordinates on the graphical interface are respectively set to A1 (x1, y1) and A2 (x2, y2), assuming that the line segment representing the usage of one-way business resources from A1 to A2 is first drawn , then the line segment cannot cover the original link. The line segment is set near A1 and A2, and the coordinates of the source and sink points are (x1+a, y1+a) and (x2+a, y2+a) respectively. a is the line segment width of the plotted link in the network topology diagram, which can be taken relative to the original link width. It is recommended to be half of the original link width value, and then based on these two new coordinate values and the business resources between A1 and A2 The occupancy rate is r1, calculated by using the method described in the description of Figure 2 and drawing a straight line representation of service resource usage and service resource idling from A1 to A2. For the line segment of the one-way service resource usage between A2 and A1, the coordinates of the source and sink points of the line segment at A1 and A2 are (x1-a, y1-a) and (x2-a, y2-a) respectively, and then according to A2 The service resource occupancy rate to A1 is r2, calculated by using the method described in the description of Figure 2 and drawing a straight line representation of service resource usage from A2 to A1. Without modifying the original network topology diagram, on the link of the original two-way service resource utilization, the proportion of service resources occupied by two unidirectional service flows can be distinguished and displayed.

The method of the present invention intuitively and succinctly displays and explains the usage and idle status of all link resources in the entire network by setting the color of the link and contacting the resource usage status and idle status on the network topology diagram of the existing network management , the operator is clear at a glance, which improves the operability and friendliness of the system.
