The too much problem of the quantity of probe data packet is sent to the network equipment in order to solve server in prior art, in the embodiment of the present invention, the task of detection network equipment is transferred in agent equipment by server, agent equipment sends probe data packet based on exploration policy to the network equipment and carries out network equipment detection, thus solves server in prior art and send the too much problem of probe data packet quantity to the network equipment.

As to the refinement detected the network equipment based on exploration policy in step 402 and expansion, the embodiment of the present invention can adopt but be not limited to following mode and realize:

First, agent equipment sends probe data packet based on exploration policy to the network equipment.

Agent equipment sends probe data packet based on the detection protocol type in exploration policy to the network equipment, often there is different detection protocol types in different exploration policy, and agent equipment will select different detection protocol types in conjunction with different exploration policy.When agent equipment execution carries out network detection to local area network, can adopt but be not limited to and use following agreement, such as, use network basic input/output (NetBios Services Protocols, NetBios) agreement, address resolution (Address Resolution Protocol, ARP) agreement; Or, use transmission to control (Transmission Control Protocol, TCP) agreement, user data package (User DatagramProtocol, UDP) agreement etc.When agent equipment perform to face local area network (LAN) carry out network detection time, can adopt but be not limited to and use following agreement, such as, use NetBios agreement; Or, use Internet to control message (Internet Control Message Protocol, ICMP) agreement, Transmission Control Protocol etc.Concrete, the protocol type that the embodiment of the present invention uses when carrying out network detection at agent equipment does not limit.

Agent equipment sends after probe data packet to the network equipment, receives the echo packet that in local area network (LAN), each network equipment returns, comprises the MAC Address of the network equipment self in echo packet.In the embodiment of the present invention, in echo packet except including the MAC Address of the network equipment self, also comprise the IP address of the network equipment self, the user name, group name etc. of the network equipment, the embodiment of the present invention does not limit the content comprised in echo packet.It should be noted that, described MAC Address is the device identification of the network equipment, and relevant MAC Address is the associated description that the detailed description of device identification please refer to about MAC Address in server side, and the embodiment of the present invention no longer repeats herein.

When agent equipment carries out network detection based on NetBios agreement to local area network, probe data packet is sent to the network equipment, the described network equipment responds this probe data packet, and sending NetBios protocol massages to agent equipment, agent equipment receives and resolves this NetBios protocol massages.Wherein, in described NetBios protocol massages, comprise source IP address, object IP address, the MAC Address, data field etc. of source MAC, gateway; Agent equipment can obtain the MAC Address of the network equipment, the information such as user name, group name of the network equipment from the data field of described NetBios protocol massages.Now, the MAC Address of the network equipment that agent equipment obtains is the MAC Address of the network equipment correct in the network equipment.But, when sending probe data packet based on NetBios agreement to the network equipment, some network equipments in this local area network (LAN) can't return echo packet to agent equipment, therefore, the quantity of the network equipment that agent equipment may be caused to detect is less than the quantity of the network equipment of the reality in local area network (LAN).

When sending probe data packet based on NetBios agreement to the network equipment for solving, some network equipments in this local area network (LAN) can not return the problem of echo packet to agent equipment, in the another kind of implementation of the embodiment of the present invention, agent equipment detects the network equipment in local area network based on ARP agreement, can ensure that each network equipment in local area network (LAN) all can return echo packet to agent equipment.When but agent equipment sends detection data based on ARP agreement to the network equipment, not only each network equipment returns echo packet to agent equipment, and LAN gateway also can return echo packet to agent equipment, carry himself MAC Address of the IP address of the network equipment in local area network and LAN gateway in the echo packet that LAN gateway returns, form gateway deception.

An arp cache table can be stored in agent equipment, about arp cache table, as described in Table 1:

Table 1

IP address	MAC Address
		192.168.1.1	00-aa-00-62-c6-09
192.168.1.2	00-aa-00-62-c5-03
		192.168.1.3	00-aa-01-75-c3-06
……	……

As can be seen from the above table, the IP address of recording in this arp cache table and MAC Address are one to one, and this buffer memory represents dynamic memory.When LAN gateway sends echo packet to agent equipment, agent equipment checks the echo packet receiving LAN gateway, and the corresponding relation of the IP address-MAC Address stored in the corresponding relation of the IP address-MAC Address in the echo packet of LAN gateway and arp cache table is compared, if comparison result is inconsistent, then the corresponding relation of previous IP address-MAC Address is updated to the corresponding relation of the IP address-MAC Address in the echo packet of the LAN gateway newly received.So, the MAC Address of himself that agent equipment provides according to LAN gateway, causes agent equipment successfully probe data packet to be sent on other network equipments.Wherein, arp cache table is only exemplary citing, and the embodiment of the present invention does not limit the content in arp cache table.

Based on the gateway deception function that gateway has himself, in the improvement project of the embodiment of the present invention, the echo packet of real echo packet and LAN gateway deception can be judged for ease of agent equipment, the MAC Address of LAN gateway, after receiving the echo packet that LAN gateway returns, is deleted by agent equipment.As shown in table 2, the corresponding relation of IP address-MAC Address that LAN gateway reports is have recorded in table 2, wherein, in table 2, the IP address of record is the IP address of the network equipment in whole local area network (LAN), and MAC Address corresponding to IP address is the MAC Address of LAN gateway.
