Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network traffic display system, and more particularly to a network traffic display system for visually grasping a link (hereinafter referred to as a traffic pattern) between respective network components on a network and a traffic amount. .

[0002]

2. Description of the Related Art Conventionally, network monitoring software or the like collects packet information transmitted on a network and displays a host on the network on a screen so that a user can visually grasp a traffic pattern and a traffic volume. When communication is performed between the host and the host, the traffic pattern connecting the corresponding host with a straight line or the like is displayed, and the thickness of the straight line,
A method of expressing traffic volume by changing attributes such as color has been adopted.

For example, Japanese Patent Application Laid-Open No. 6-34862 discloses a method of displaying a traffic pattern between hosts.
There is Japanese Patent Publication No. 2 “Network analysis method”. In this conventional network traffic display method, as shown in FIG. 15, a host (node) on a network is displayed as a point on the circumference, and communication between a certain host on the network and another host has occurred. In this case, a traffic pattern in which points corresponding to each host on the circumference are connected by a straight line is displayed to indicate that communication has occurred.

[0004] As a method of expressing the traffic volume, there is Japanese Patent Application Laid-Open No. 8-181711, entitled "Method of Displaying Traffic Volume". In this conventional network traffic display method, the amount of traffic is changed by changing attributes such as the type, color, and shape of a straight line constituting the traffic pattern, or displayed numerically near the straight line constituting the traffic pattern.

[0005]

However, these conventional techniques have the following problems.

[0006] The first problem is that it is difficult to cope with a large-scale network having a large number of hosts. The reason is that if you have a large network with many hosts,
In order to display all the hosts on the circumference, the number of links (traffic patterns) connecting the hosts becomes enormous, and it becomes difficult to find traffic between specific network components.

The second problem is not only the traffic pattern and traffic volume between small network components such as between hosts, but also the host, segment (refers to a set of hosts), and subnetwork (host, segment, etc.). This means that it is difficult to grasp a large traffic pattern and traffic volume of the entire network between network components such as a set connected via a line. The reason is that the conventional network traffic display method has only means for displaying the traffic pattern and the traffic volume between the hosts.

[0008] It is an object of the present invention to provide a network traffic display system capable of easily grasping a traffic pattern and a traffic volume even in a network having a large number of communicating hosts.

Another object of the present invention is to provide not only host-to-host traffic but also host, segment,

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a network traffic display system according to the first embodiment of the present invention. The network traffic display method according to the present embodiment includes a network configuration display panel 10,
The traffic display panel 20, the network configuration display means 30, the traffic display means 40, the connection relation table 50, the inclusion relation table 60, and the traffic table 70 constitute the main part. The “panel” means a screen of the image display device or one area displayed thereon.

The network configuration display panel 10 is shown in FIG.
As illustrated in (a), a sub-network 11 and a segment 12 which are logical components of a network
And a router 13 which is a physical component of the network.
And switches 14 and their inclusion relations and connection relations in a hierarchical diagram (hereinafter referred to as a network configuration diagram).
Display as

Here, the inclusion relation means that the subnetwork 11 includes a segment 12 and the segment 12 further includes a host. For example, in FIG.
The sub-network Net1 includes a segment Seg1, and the sub-network Net2 includes three segments Seg2, Seg3 and Se separated by a switch Sw1.
There is an inclusion relationship that includes g4. These inclusion relations are expressed in a form that the icon of the segment 12 exists in the area of the sub-network 11. Although not illustrated in the network display panel 10 of FIG. 2A, there is an inclusion relationship that the segment 12 includes a host.

On the other hand, the connection relationship is expressed by connecting the icons of the router 13, the switch 14 and the segment 12 with lines. Taking FIG. 2 (a) as an example, router Ro
is connected to the segment Seg1 and the switch Sw1, and the switch Sw1 has three segments Se.
g2, Seg3 and Seg4 are connected.

The sub-networks 11, segments 12, routers 13 and switches 14, which are network components on the network configuration display panel 10, can be selected with a pointing device such as a mouse.
The traffic pattern and the traffic volume related to each network component included in the selected network component are displayed on the traffic display panel 20. For example, when the sub-network 11 is selected on the network configuration display panel 10, all the segments 23 in the selected sub-network 22 are displayed on the circumference 21 on the traffic display panel 20. When the segment 12 is selected on the network configuration display panel 10, all the hosts 24 in the selected segment 23 are displayed on the circumference 21 on the traffic display panel 20.

2, Seg3 and Seg4 are divided by broken line segment 27. When data communication is performed between the network components displayed on the circumference 21, a traffic pattern is drawn by a straight line 25 connecting the icons of the network components, and the traffic amount is represented by the thickness of the straight line 25. The thickness of the straight line 25 is determined by summing the traffic volume of the host 24 and the traffic volume of all the hosts 24 in the segment 23 and the subnetwork 22. Thereby, not only the traffic pattern and the traffic volume of the host 24 to the host 24 but also the traffic pattern and the traffic volume between the subnetwork 22, the segment 23 and the host 24 can be displayed.

When each icon representing a network element on the circle 21 is selected with a pointing device such as a mouse, the network element contained in the network element is expanded and displayed. In the case of the sub-network 22, all the segments 23 in the sub-network 22 are displayed on the circumference 21 in the case of the segment 23, and in the case of the segment 23, all the hosts 24 in the segment 23 are displayed.

More specifically, the traffic display means 40
Since the network element at one end on the circumference is the subnetwork Net1 (step S401), the segments included in the subnetwork Net1 are listed with reference to the inclusion relation table 60 (step S402),
Hosts included in the listed segments are listed with reference to the inclusion relation table 60 (step S4).
03). Here, this list is referred to as a node list 1.
Next, the traffic display means 40 lists all the traffic that is the transmission source of the host in the node list 1 (step S407). Here, this list is referred to as a traffic list 1. Subsequently, the traffic display means 40 lists the hosts included in the sub-network Net2, which is the network element at the other end on the circumference (step S408). Here, this list is referred to as a node list 2. Next, the traffic display means 40
Lists the traffic of the traffic list 1 that has the host of the node list 2 as the transmission destination (step S409). Here, this list is referred to as a traffic list 2. Then, the traffic display means 4
0 calculates the total traffic volume of the traffic in the traffic list 2 with reference to the traffic table 70 (step S410). Finally, the traffic display means 40 determines the thickness of the line according to the traffic volume and displays a straight line between the sub-networks Net1 and Net2, which are network components at both ends on the circumference (step S411).

Thereafter, the network configuration display panel 10
When the sub-network Net2 is selected in the above, the network configuration display means 30 sets the icon of the sub-network Net2 to the selected state (see FIG. 11B), and determines whether the selected network element is a sub-network. (Step S501), since the network is a subnetwork, the traffic display means 40

305).

More specifically, the traffic display means 40
First, it is determined whether the segments Seg2, Seg3, and Seg4, which are network components at one end on the circumference, are sub-networks (step S401).
Since it is not a subnetwork, it is determined whether or not there is a segment (step S404). Since it is a segment, the segment Seg is referred to by referring to the inclusion relation table 60.
2. Hosts included in Seg3 and Seg4 are listed (step S405). Here, this list is referred to as a node list 1. Next, the traffic display means 40
Lists all the traffic that is the transmission source of the host in the node list 1 (step S407). Here, this list is referred to as a traffic list 1. Subsequently, the traffic display unit 40 lists the hosts included in the subnetwork Net1, which is the network element at the other end on the circumference (step S408). Here, this list is referred to as a node list 2. Next, the traffic display means 40 lists the traffic of the traffic list 1 having the host of the node list 2 as the transmission destination (step S409). here,
This list is referred to as traffic list 2. Subsequently, the traffic display means 40 displays the traffic table 70

Finally, the traffic display means 40 determines the thickness of the line according to the traffic volume, and determines the segments Seg2, Seg3 and Se, which are the network components at both ends on the circumference.
A straight line is displayed between g4 and the sub-network Net1 (step S411) (see FIG. 11B).

Thereafter, the network configuration display panel 10
If the segment Seg3 is selected in the above, the network configuration display means 30 sets the icon of the segment Seg3 to the selected state (see FIG. 11C), and determines whether the selected network component is a subnetwork (see FIG. 11C). Step S501) Since it is not a subnetwork, it is determined whether or not it is a segment (Step 503). Since it is a segment, it is notified to the traffic display means 40, and a process at the time of element selection for the corresponding segment Seg3 on the circumference. (See FIG. 8) (step S504).

Also, when the segment Seg3 is selected on the traffic display panel 20, the traffic display means 40 notifies the network configuration display means 30 to make the icon of the segment Seg3 also selected on the network configuration display panel 10. (See FIG. 11 (c)) and the corresponding segment S on the circumference.
The processing at the time of element selection (see FIG. 8) is performed for eg3.

In the process at the time of element selection (see FIG. 8), the traffic display means 40 specifies a network element on the selected circumference as the segment Seg3 (step S301), and determines whether or not it is a subnetwork. (Step S302), it is determined whether or not the segment is a segment because it is not a subnetwork (Step S302).
306). Now, since it is a segment, the traffic display means 40 refers to the inclusion relation table 60 and the hosts Host31 and Host32 in the segment Seg3.
And Host33 are determined (step S307), and their host Host3 is used instead of the segment Seg3.
1, Host32 and Host33 are displayed on the circumference (step S308), and the hosts Host31, Host32 and Host33 displayed with reference to the traffic table 70 and the sub-network Net1 and the segment, which are other network components on the circumference, are displayed. S
The traffic amount between eg2 and Seg4 is calculated, and the traffic pattern and the traffic amount are displayed (step S309).

More specifically, the traffic display means 40
First, it is determined whether or not the hosts Host31, Host32, and Host33, which are network components at one end on the circumference, are sub-networks (step S4).
01), since it is not a subnetwork, it is determined whether or not there is a segment (step S404). Since it is not a segment but a host, it refers to the inclusion relation table 60 and its hosts Host31, Host32 and Host.
Add t33 to node list 1 (step S40)
6). Next, the traffic display means 40 lists all the traffic that is the transmission source of the host in the node list 1 (step S407). Here, this list is referred to as a traffic list 1. Subsequently, the traffic display unit 40 lists the hosts included in the sub-network Net1 and the segments Seg2 and Seg4, which are the other network components on the circumference (step S408). Here, this list is referred to as a node list 2. Next, the traffic display means 40
The traffic of the traffic list 1 having the host of the node list 2 as the transmission destination is listed (step S409). Here, this list is referred to as a traffic list 2. Subsequently, the traffic display means 40
Calculates the total traffic volume of the traffic in the traffic list 2 with reference to the traffic table 70 (step S410). Finally, the traffic display means 40 determines the thickness of the line according to the traffic volume, and determines whether the host Ho, which is a network component at both ends on the circumference,
