The flow chart of the acquisition methods of gateway provided in an embodiment of the present invention as shown in Figure 2.Refer to Fig. 2, this method
Including：
Step S110：Obtain the indirect route list item in the routing table information of the network equipment.
In NMS, it is found that the related information of network must determine the gateway of subnet.The embodiment of the present invention carries
The acquisition methods of the gateway of confession carry out the acquisition of subnet gateway according to the routing table information of the network equipment.Due to routing table information
Direct routing list item represents to be routed directly to connected subnet in route table items, i.e., destination address directly with the network equipment phase
Even, it is understood that be the interface IP that destination address is the network equipment, therefore the subnet be known to subnet, the subnet
Information be also known state, for example, as it is known that the gateway of the subnet.And indirect route list item represent be routed to non-local main frame,
Subnet where network or subnet, i.e. destination address is not directly to be connected with the router, it is necessary at least passes through a road again
By device, therefore the information of the subnet where destination address is unknown, and the gateway of subnet is unknown.And it is possible to pass through indirect route
List item obtains subnet corresponding to destination address, and determines the gateway of the subnet.
It is possible, firstly, to obtain the routing table information of the network equipment.Therefore, before step S110, the acquisition side of the gateway
Method also includes：
Step S100：Routing table information is obtained based on default NMP.
There is NMP in NMS, NMP is as most heavy in network of network system
The part wanted, define the communication means between network manager and network management agent.Such as SNMP (Simple Network
Management Protocol, Simple Network Management Protocol), CMIP (Common Management Information
Protocol, CMIP) etc..
In embodiments of the present invention, default NMP can be snmp protocol, and snmp protocol is used for network node,
Such as router, interchanger etc..The routing table information of the network equipment can be obtained by snmp protocol.Certainly, network is preset
The specific agreement of management agreement is not intended as limiting in embodiments of the present invention.
Further, in the routing table information of the network equipment obtained by snmp protocol, including multiple route table items.
There is the routing information for reaching specific destination in routing table information, multiple route table items have corresponded to the phase for reaching specific destination
Close information.Also, include direct routing list item and indirect route list item in route table items.
After the routing table information of the network equipment is got, then obtain the indirect route list item in routing table information.
Specifically, the indirect route list item in obtaining the routing table information of the network equipment can include：
When judging the value of the route-type of a route table items in the routing table information of the network equipment for preset value, then really
The fixed route table items are indirect route list item.
In the route-type value of the route table items in judging the routing table information of the network equipment, road should be first obtained
By the route-type value of the route table items in table information.
Specifically, the route table items in routing table information can be traveled through, MIB node is pRouteType value is obtained, i.e., should
The value of route-type corresponding to route table items.
In snmp protocol, when ipRouteType value is 3, it is direct routing list item to represent the route table items；When
When ipRouteType value is 4, it is indirect route list item to represent the route table items.
Therefore, in embodiments of the present invention, preset value can be corresponding with the indirect route types value in snmp protocol
Value, i.e., preset value could be arranged to 4.
It is then possible to whether the route-type value of a route table items is the pre- of setting in the routing table information for judging to obtain again
If value.
When the route-type value for judging the route table items is preset value, then it is indirect road that can determine the route table items
By list item.
Step S120：Son is determined based on the subnet mask of destination address and destination corresponding to the indirect route list item
Net.
After the indirect route list item in getting routing table information, then obtain destination corresponding to indirect route list item
Subnet where location.
In embodiments of the present invention, destination address and the route table items pair corresponding to the indirect route list item can be based on
The subnet mask for the destination answered determines subnet.
Specifically, MIB node i pRouteDest are obtained, to obtain destination address corresponding to the indirect route list item；Obtain
MIB node i pRouteMask, to obtain the subnet mask of destination corresponding to the indirect route list item.
Then the son by the destination corresponding with the indirect route list item of destination address corresponding to the indirect route list item then,
Net mask phase is with determining the subnet where destination address corresponding to the indirect route list item.
Specifically by the subnet of the destination corresponding with the indirect route list item of destination address corresponding to the indirect route list item
Mask phase with can respectively be indicated destination address and subnet mask with binary system, then by same position number mutually with that is,
According to 1 with 1 phase with 1,1 with 0 phase with 0,0 with 0 phase with 0 regular work and computing, to obtain the indirect route list item pair
Subnet where the destination address answered.
For example, destination address corresponding to the indirect route list item is 192.9.200.13, corresponding to the indirect route list item
The subnet mask of destination is 255.255.255.0.By destination address 192.9.200.13 and subnet mask 255.255.255.0
Mutually with that can be, destination address 192.9.200.13 be converted into binary system, obtains 11,000,000 00001001
1100100000001101, subnet mask is converted into binary system, obtains 11,111,111 1111111111111111
00000000, then by 11,000,000 00,001,001 11,001,000 00001101, with 11,111,111 11111111
11111111 00000000 phases with, obtain 1,100,000,000,001,001 11,001,000 00000000, i.e. 192.9.200.0, this
Address is the network address of subnet where destination address.
It is thus possible to obtain based on purpose corresponding to destination address corresponding to the indirect route list item and the route table items
Ground subnet mask phase and the network address of the subnet, i.e. subnet corresponding to the indirect route list item where destination address that determine.

The subnet obtained in step S120.
Specifically, can treat whether the IP for judging the network equipment to be determined belongs to the subnet that is obtained in step 120
Determine the subnet mask phase of the IP of the network equipment and the subnet with, obtain mutually with result, wherein, the subnet mask of the subnet is
The subnet mask of destination corresponding to the indirect route list item obtained in step S120；Then judge again obtain phase with knot
Whether the network address of subnet of the fruit with being obtained in step S120 is identical, if identical, then it represents that the IP of the network equipment to be determined
Belong in step S120 the subnet obtained.
For example, using in step 120 for example, the IP of the network equipment to be determined is converted to two as 192.9.200.14
After system, 11,000,000 00,001,001 1100100000010001, then the subnet mask with being illustrated in step S120 are obtained
255.255.255.0 corresponding 11,111,111 11,111,111 11,111,111 00000000 phase is with obtaining 11000000
0000100111001000 00000000, i.e. 192.9.200.0, mutually with result 192.9.200.0 with being illustrated in step S120
The network address of the subnet of acquisition is identical, and therefore, the IP of the network equipment to be determined belongs to mesh corresponding to the indirect route list item
Address where subnet.
When judged result for when being, i.e., one or more corresponding to next hop router address corresponding to indirect route list item
In the individual network equipment to be determined, the IP for having the network equipment to be determined belongs to where destination address corresponding to the indirect route list item
Subnet, it may be determined that the gateway of the network equipment to be determined as the subnet.
It is thus possible to the routing table information obtained based on the NMP utilized in NMS, between acquisition
Connect the gateway of the subnet where destination address corresponding to route table items.Solve and determine that the gateway of subnet holds by hand in the prior art
It is error-prone and by server possibly can not obtain the gateway of subnet the problem of.
It is applied to by the acquisition methods of gateway provided in an embodiment of the present invention in NMS, it is necessary to obtain all
