In the embodiment of the present invention, can on each authenticating device, configure the jumping figure that authenticating device arrives certificate server.As shown in Figure 1, due to convergence-level equipment and certificate server direct-connected, therefore on convergence-level equipment, configuring the jumping figure that convergence-level equipment arrives certificate server is 0; Due between access layer equipment 1 (or access layer equipment 2, access layer equipment 3) and certificate server every an equipment (being convergence-level equipment), therefore on access layer equipment 1, configuring the jumping figure that access layer equipment 1 arrives certificate server is 1.Further, can also on each authenticating device, configure the disposal ability of authenticating device, the disposal ability of authenticating device represents that authenticating device can carry out the Authentication Client number of authentication processing; If the disposal ability of authenticating device changes, on authenticating device, reconfigure the disposal ability of authenticating device.For example, the disposal ability that configures convergence-level equipment on convergence-level equipment is 10000, the disposal ability that configures access layer equipment 1 on access layer equipment 1 is 1000, the disposal ability that configures access layer equipment 2 on access layer equipment 2 is 1000, and the disposal ability that configures access layer equipment 3 on access layer equipment 3 is 1000.
Further, authenticating device based on configuring on each authenticating device arrives the jumping figure of certificate server, and the disposal ability of the authenticating device configuring on each authenticating device, each authenticating device can be safeguarded authentication capability table in the manner described above, and in this authentication capability table, record the role of each authenticating device in authentication aggregation group, disposal ability and the Authentication Client number of working as pre-treatment.
Under the application scenarios shown in Fig. 1, the jumping figure that arrives certificate server due to convergence-level equipment is 0, the jumping figure that each access layer equipment (access layer equipment 1, access layer equipment 2, access layer equipment 3) arrives certificate server is 1, therefore the role of convergence-level equipment is Master authenticating device, and the role of each access layer equipment is Slave authenticating device.Based on this, convergence-level equipment sends authentication statistics request message to each access layer equipment, each access layer equipment is after receiving authentication statistics request message, to convergence-level equipment return authentication statistics response message, and the disposal ability of having carried access layer equipment in authentication statistics response message, access layer equipment is when the Authentication Client number of pre-treatment.Convergence-level equipment receives the authentication statistics response message that each access layer equipment returns, and utilizes the information of carrying in authentication statistics response message on this convergence-level equipment, to safeguard authentication capability table, and authentication capability table is sent to each access layer equipment.Each access layer equipment receives the authentication capability table from convergence-level equipment, and on this access layer equipment, safeguards this authentication capability table.
As shown in table 1, be the example of the authentication capability table safeguarded on convergence-level equipment and each access layer equipment.
Table 1
| ? | Jumping figure | Role | Disposal ability | Authentication Client number |
| Convergence-level equipment | 0 | Master authenticating device | 10000 | 2000 |
| Access layer equipment 1 | 1 | Slave authenticating device | 1000 | 500 |
| Access layer equipment 2 | 1 | Slave authenticating device | 1000 | 500 |
| Access layer equipment 3 | 1 | Slave authenticating device | 1000 | 500 |
In the embodiment of the present invention, convergence-level equipment periodic to each access layer equipment, send authentication statistics request message, be that the authentication capability table shown in convergence-level equipment meeting his-and-hers watches 1 regularly upgrades, and the authentication capability table after upgrading is sent to each access layer equipment, by each access layer equipment, upgrade authentication capability table.
In the embodiment of the present invention, can control VLAN (Virtual Local Area Network for the configuration of authentication aggregation group, VLAN), and above-mentioned authentication statistics request message, authentication statistics response message and the message that has carried the information of authentication capability table all need to be propagated in this controls VLAN.
In the embodiment of the present invention, by above-mentioned control VLAN interface, the interface towards network authentication server side is called to east orientation interface, the interface towards user's side is called to west to interface.For example, on convergence-level equipment, interface 1 is east orientation interface, and interface 2, interface 3 and interface 4 are that west is to interface.On access layer equipment 1, interface 5 is east orientation interface, and interface 8 is that west is to interface.On access layer equipment 2, interface 6 is east orientation interface, and interface 9 is that west is to interface.On access layer equipment 3, interface 7 is east orientation interface, and interface 10 is that west is to interface.
In the embodiment of the present invention, in authentication statistics response message, also carry the IP address and the IP address of west to interface of the east orientation interface of access layer equipment, make convergence-level equipment can utilize the information of carrying in authentication statistics response message in authentication capability table, to record IP address and the western IP address to interface of east orientation interface.
Step 202, Slave authenticating device, when receiving message identifying, is inquired about this authenticating device and is worked as the disposal ability whether the Authentication Client number of pre-treatment reaches this authenticating device from authentication capability table; If do not reached, perform step 203; If reached, perform step 206.
As shown in Figure 1, in the verification process of Authentication Client, Authentication Client can send message identifying, access layer equipment 1 is when receiving this message identifying by west to interface, authentication capability table shown in question blank 1, to determine whether access layer equipment 1 reaches the disposal ability of access layer equipment 1 when the Authentication Client number of pre-treatment.In table 1, the Authentication Client number that access layer equipment 1 is worked as pre-treatment is 500, and the disposal ability of access layer equipment 1 is 1000, therefore judgment result is that and does not reach, execution step 203.
Step 203, Slave authenticating device carries out authentication processing to message identifying.
Step 204, if the message identifying after authentication processing need to be sent to certificate server, in the message identifying of Slave authenticating device after authentication processing, add for representing current the second mark that has carried out authentication processing of message identifying, and the message identifying after authentication processing is sent to Master authenticating device.
Step 205, Master authenticating device, after having received from carrying of Slave authenticating device the message identifying of the second mark, directly sends to certificate server by this message identifying.
As shown in Figure 1, after 1 pair of message identifying of access layer equipment carries out authentication processing, if the message identifying after authentication processing need to be sent to certificate server, in the message identifying after authentication processing, add for representing current the second mark that has carried out authentication processing of message identifying, and by east orientation interface, the message identifying after authentication processing is sent to convergence-level equipment.Convergence-level equipment is after receiving by west the message identifying that has carried the second mark to interface, because the second mark is used for representing that message identifying is current has carried out authentication processing, so convergence-level equipment can directly send to certificate server by message identifying.
Step 206, Slave authenticating device adds for representing current the first mark that does not carry out authentication processing of this message identifying in message identifying, and this message identifying is sent to Master authenticating device.
Step 207, Master authenticating device, when receiving the message identifying that has carried the first mark, is inquired about this authenticating device and is worked as the disposal ability whether the Authentication Client number of pre-treatment reaches this authenticating device from authentication capability table; If not, perform step 208; If so, perform step 209.
Step 208, Master authenticating device carries out authentication processing to message identifying.
Wherein, if the message identifying after authentication processing need to be sent to certificate server, Master authenticating device also needs the message identifying after authentication processing to send to certificate server.
Step 209, Master authenticating device is inquired about the disposal ability that the Authentication Client number that whether has Slave authenticating device to work as pre-treatment does not reach this Slave authenticating device from authentication capability table; If so, perform step 210; If not, can abandon this message identifying, and perform step 211.
Step 210, Master authenticating device sends to message identifying the Slave authenticating device (not reaching the Slave authenticating device of disposal ability when the Authentication Client number of pre-treatment) inquiring, and by this Slave authenticating device, message identifying is carried out to authentication processing.Further, if the message identifying after authentication processing need to be sent to certificate server, in the message identifying of this Slave authenticating device after authentication processing, add for representing current the second mark that has carried out authentication processing of message identifying, and the message identifying after authentication processing is sent to Master authenticating device.Master authenticating device, after having received from carrying of Slave authenticating device the message identifying of the second mark, directly sends to certificate server by this message identifying.
Step 211, Master authenticating device sends warning message to Network Management Equipment, and in this warning message, has carried this authenticating device and each Slave authenticating device all cannot carry out to Authentication Client the information of authentication processing.Wherein, described warning message specifically includes but not limited to SNMP (Simple Network Management Protocol, Simple Network Management Protocol) warning message.
For step 206-step 211, as shown in Figure 1, access layer equipment 1 is when receiving message identifying, message identifying is not carried out to authentication processing, directly in message identifying, add for representing current the first mark that does not carry out authentication processing of message identifying, and by east orientation interface, message identifying is sent to convergence-level equipment.Convergence-level equipment is when receiving to interface the message identifying that has carried the first mark by west, because the first mark is used for representing the current authentication processing of not carrying out of message identifying, therefore the authentication capability table shown in convergence-level equipment query table 1, to determine whether convergence-level equipment reaches the disposal ability of convergence-level equipment when the Authentication Client number of pre-treatment; If do not reach the disposal ability of convergence-level equipment, convergence-level equipment carries out authentication processing to message identifying, and the message identifying after authentication processing is sent to certificate server.
If reach the disposal ability of convergence-level equipment, the authentication capability table shown in convergence-level equipment query table 1, to determine that the Authentication Client number that whether has access layer equipment to work as pre-treatment in authentication capability table does not reach the disposal ability of this access layer equipment.If not, convergence-level equipment abandons message identifying, and sends warning message to Network Management Equipment.If, suppose that access layer equipment 2 does not reach the disposal ability of access layer equipment 2 when the Authentication Client number of pre-treatment, convergence-level equipment sends to access layer equipment 2 by message identifying, 2 pairs of message identifyings of access layer equipment carry out authentication processing, if the message identifying after authentication processing need to be sent to certificate server, message identifying is carried out after authentication processing, in message identifying after authentication processing, add for representing current the second mark that has carried out authentication processing of message identifying, and by east orientation interface, the message identifying after authentication processing is sent to convergence-level equipment.Convergence-level equipment, after receiving by west the message identifying that has carried the second mark to interface, because the second mark is used for representing the current authentication processing of having carried out of message identifying, therefore can directly send to certificate server by message identifying.
In the embodiment of the present invention, the message identifying that Slave authenticating device sends to Master authenticating device, can adopt the packaged type of two layers of unicast message or the packaged type of employing multicast message.
In the embodiment of the present invention, Master authenticating device, after Network Management Equipment sends warning message, can be analyzed by Network Management Equipment the fail safe of current network, and when network is dangerous, authenticating device be protected.For example, Network Management Equipment can be analyzed the attack whether network is subject to message identifying, and whether analytical attack person has forged a large amount of message identifyings, thereby has taken the resource of a large amount of authenticating devices.
Further, Master authenticating device is after Network Management Equipment sends warning message, Master authenticating device can also send warning message to each Slave authenticating device, has carried Master authenticating device and each Slave authenticating device and all cannot carry out to Authentication Client the information of authentication processing in this warning message.By each Slave authenticating device, after receiving warning message, directly abandon the message identifying of receiving, no longer this message identifying is carried out to authentication processing, also no longer this message identifying is sent to Master authenticating device.
In the embodiment of the present invention, convergence-level equipment and each access layer equipment are after safeguarding authentication capability table, if the disposal ability of convergence-level equipment has actual value (as 10000), and the disposal ability of each access layer equipment do not have actual value (as 0 or Null) or each access layer equipment do not support Authentication Client to carry out authentication processing, the authentication processing of all clients is undertaken by convergence-level equipment, in this situation embodiment of the present invention, repeats no more.If the disposal ability of convergence-level equipment do not have actual value (as 0 or Null) or convergence-level equipment do not support Authentication Client to carry out authentication processing, and the disposal ability of each access layer equipment has actual value (as 1000), the authentication processing of all clients is undertaken by each access layer equipment, in this situation embodiment of the present invention, repeats no more.
Based on technique scheme, in the embodiment of the present invention, by a plurality of authenticating devices (as a convergence-level equipment and a plurality of access layer equipment) being formed to authentication aggregation group, and use a convergence-level equipment and a plurality of access layer equipment in authentication aggregation group to carry out authentication processing to Authentication Client, thereby avoid only using a convergence-level equipment to carry out authentication processing, alleviate the processing load of convergence-level equipment, avoid causing the bottleneck of network authentication, and can promote the inclusive authentication ability of network, improve the reliability of authentication.
