Problems solved by technology

The two collection tasks belong to different devices and have no relationship, so necessary analysis such as historical trends cannot be viewed, resulting in discontinuous management
[0009] 2. When the address of a dynamic address device is assigned to other devices, the management information may be disordered
If the address of device A is assigned to device B after it is released, then for NMS, the communication of device A will be considered normal, but in fact at this time, device A in NMS has been wrongly mapped to device B, and various management information is disordered.
[0010] 3. Periodic automatic discovery makes device information not updated in time
For devices that are already running on the Internet, due to limitations in hardware and other aspects, they are not even upgradeable.
This makes the program unfeasible
[0015] 2. Access efficiency is much lower than SNMP
In a non-NAT environment, when the network management system actively initiates an access request, an additional communication is required
[0016] 3. Insufficient standardization of network protocols
Since the registered port must be known, this requires that the ports provided by the network management must be limited. When the network scale is large, it will inevitably lead to poor performance.
Of course, it is also possible to use each device to register with different ports, but in this way, not only the configuration management is quite complicated, but also there are performance problems because the network management system needs to monitor a large number of ports.
[0021] 2. Taking the IP address as the unique identifier of the device will also lead to discontinuous management and information disorder
[0022] 3. In addition to SNMP, traditional management protocols such as Telnet and ping are also used. Therefore, when multiple management protocols are used at the same time, multiple tunnels are required, which not only makes the performance problem more serious, but also leads to an increase in transformation costs.
[0023] It can be seen from the above that the current dynamic address device management method cannot guarantee the simplicity of network transformation and the continuity of device management at the same time

Embodiment 1

[0095] In this embodiment, the agent device adopts the first method to acquire information about address changes, that is, when a device with a dynamic address changes in address, the device notifies the agent device of information about address changes.

[0096] Figure 5 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 1 of the present invention. Such as Figure 5 As shown, the method includes:

[0097] Step 501, pre-setting a device identifier for a device with a dynamic address.

[0098] In this step, the device identifier set for the device with a dynamic address is a unique fixed identifier on the entire network within the management life cycle, which can be specifically: the host name of the device, the domain name assigned to the device by DNS, the MAC address corresponding to the management address, The lowest sorted MAC address or newly defined identification information on the device.

[0099] Assuming that the address...

Embodiment 2

[0133] In this embodiment, the second approach is adopted to acquire information related to address changes, that is, when the DHCP server allocates an address for a device with a dynamic address, it sends the allocated address information to the agent device.

[0134] Figure 8 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 2 of the present invention. Such as Figure 8 As shown, the method includes:

[0135] Step 801, pre-setting a device identifier for a device with a dynamic address.

[0136] This step is the same as step 501 in the first embodiment, and will not be repeated here.

[0137] Assume that the original IP address of device A with a dynamic address is IP1, and the DHCP server reassigns IP address IP2 to device A, and the identifier of the device with a dynamic address is ID1, then perform the following steps:

[0138] In step 802, the DHCP server sends the device identifier and the assigned address of the dynamic ...

Embodiment 3

[0176] In this embodiment, the agent device adopts a third way to obtain information about address changes, that is, the agent device actively inquires about address changes of the dynamic address device.

[0177] Figure 11 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 3 of the present invention. Such as Figure 11 As shown, the method includes:

[0178] Step 1101, pre-setting an identifier for a dynamic address device.

[0179] This step is the same as step 501 in the first embodiment, and will not be repeated here.

[0180] Assuming that the address of the dynamic address device A changes, its IP address changes from the original IP1 to IP2, and the identifier of the dynamic address device is ID1, then perform the following steps:

[0181] In step 1102, the agent device actively detects whether the device identifiers corresponding to the stored IP addresses have changed, and if there is a change, execute step 1103; otherwis...

Abstract

The invention discloses a method for managing dynamic address equipment, which includes an agent device connected to a network management system NMS in the network. The method includes: setting a fixed equipment identification for the dynamic address equipment; the agent device acquires the dynamic address where the address changes The device ID and the changed address of the device, and notify the NMS; the NMS uses the received notification to determine the dynamic address device whose address has changed, and updates the current IP address of the dynamic address device. The invention also discloses an agent device for managing dynamic address equipment. By applying the present invention, the management of dynamic address equipment can be realized conveniently, and the continuity of management information can be guaranteed.

Description

technical field [0001] The invention relates to network equipment management technology, in particular to a method and agent device for managing dynamic address equipment. Background technique [0002] With the continuous development of Internet technology, the scale of the network continues to expand, and the complexity of the network continues to increase. More and more computers use dynamically assigned IP addresses, which are called dynamic address devices. In the above network environment, there are one or several Dynamic Address Assignment Protocol (DHCP) servers to assign addresses to other devices and computers. [0003] Network Management System (NMS) is a system for managing network devices. In traditional NMS, it is assumed that: at any time after a device is added to the NMS, the device has a unique and constant management IP address (this address may also is one of the service addresses), and the NMS accesses the device through the management IP address to obta...
