Abstract
The invention discloses a method and a device for modifying the IP address of equipment. The method comprises the following steps that: first equipment broadcasts an activation request to all equipment in a local area network and receives an activation response, wherein the activation response comprises equipment basic information of the equipment initiating the activation response; and when determining that the equipment initiating the activation response is nonactivated equipment according to the equipment basic information, the first equipment adds the nonactivated equipment as activated equipment, and initiates an IP address updating request to the activated equipment, wherein the IP address updating request comprises the IP address and port number specified by the activated equipment. Through the method and the device, the IP address of the equipment can be efficiently modified and can also be remotely controlled.
Description
Technical field
The present invention relates to communication technical field, particularly a kind of method and device of revising IP address of equipment.
Background technology
For the equipment of unknown IP address, can't pass through client or server software realization control and management to this equipment.Be that existing software by network remote control and management equipment all is based on the known prerequisite of IP address of equipment, could realize revising information such as IP address of equipment, subnet mask.
At present, IP address alter mode for new networked devices is, new networked devices is connected to client or server end application software by serial ports, obtain the original equipment IP address of this equipment to be activated, afterwards, again according to the requirement of current network, revise this original equipment IP address (the original equipment IP address that common identical device is provided with all is identical) when dispatching from the factory, thereby make this equipment to be activated obtain available network ip address, realize the modification of IP address of equipment.Afterwards, can equipment that revise the IP address be managed by the software of network remote control and management equipment, as parameter configuration, warning and audio alert feature operation etc.
As seen, there is following problem at least in the existing mode of revising the IP address:
1) use is limited, needs to be equipped with in addition Serial Port Line.Because equipment such as web camera have carried out external packing when dispatching from the factory, open external packing one by one and just can carry out the serial ports butt joint, thus the IP address of revising each equipment, it is low to revise efficient;
2) inconvenient operation because need Serial Port Line, can only adapt to in-plant connection, can not realize remote control.
Summary of the invention
The embodiment of the invention provides a kind of method and device of revising IP address of equipment, the IP address that can revise equipment efficiently, and can control by long-range.
The embodiment of the invention provides a kind of method of revising IP address of equipment, and described method comprises:
The all devices broadcasting of first equipment in local area network (LAN) activates request, receives to activate and replys; Wherein, comprise the equipment essential information of initiating to activate answering equipment during described activation is replied;
When described first equipment determines that according to described equipment essential information initiating to activate the equipment of replying is un-activation equipment, adding described un-activation equipment is activated equipment, afterwards, initiate to upgrade the IP Address requests to described activated equipment, comprise in the described renewal IP Address requests that first equipment is the IP address and the port numbers of described activated equipment appointment.
Wherein, described method also comprises:
Described first equipment receives and upgrades the IP address and reply, from reply described renewals IP address, know that IP address and port numbers are upgraded successfully after, affirmation IP revises successfully the address.
Wherein, determine to initiate to activate the equipment of replying according to described equipment essential information be that the step of un-activation equipment comprises to described first equipment:
Described first equipment obtains the unique identification information of initiating to activate the equipment of replying from described equipment essential information;
Judge whether described unique identification information has been kept at this locality, if then described initiation activates the equipment of replying and is activated equipment, otherwise the equipment that described initiation activation is replied is un-activation equipment.
Wherein, the unique identification information of described equipment comprises at least: the sequence number of equipment and/or physical address.
Wherein, described equipment essential information can also comprise IP address of equipment, subnet mask, device name, port numbers and software and hardware version information.
Wherein, described activation request, activate and to reply, to upgrade the IP Address requests and upgrade the IP address and reply respectively and comprise: destination address field (DAF), source address field, the type field that is used to identify last layer institute use agreement, data field and frame check field.
Wherein, described data field comprises at least:
Protocol identification field, Equipment Serial Number field, datagram length field, datagram sequence-number field, order type field, command code field, source physical address field.
The embodiment of the invention also provides a kind of device of revising IP address of equipment, comprising:
First request transmitting unit is used for activating request to all devices broadcasting of local area network (LAN);
The first request receiving element is used for receiving activating and replys; Wherein, comprise the equipment essential information of initiating to activate answering equipment during described activation is replied;
The equipment adding device, when being used for determine to initiate activating the equipment of replying and being un-activation equipment according to described equipment essential information, adding described un-activation equipment is activated equipment, afterwards, notifies second request transmitting unit;
Second request transmitting unit is used for initiating to upgrade the IP Address requests to described activated equipment, comprises in the described renewal IP Address requests that first equipment is the IP address and the port numbers of described activated equipment appointment.
Wherein, described device also comprises:
The second request receiving element is used for receive upgrading the IP address and replys, from reply described renewals IP address, know that IP address and port numbers are upgraded successfully after, affirmation IP revises successfully the address.
Wherein, described activation request, activate and to reply, to upgrade the IP Address requests and upgrade the IP address and reply respectively and comprise: destination address field (DAF), source address field, the type field that is used to identify last layer institute use agreement, data field and frame check field.
Wherein, described data field comprises:
