Specifically describe the preferred embodiments of the present invention below in conjunction with accompanying drawing, wherein, accompanying drawing constitutes the application's part, and is used from explaination principle of the present invention with embodiments of the invention one.For clear and simplification purpose, when it may make theme of the present invention smudgy, with specifying in detail of known function and structure in the omission device described herein.
1 pair of the method for the invention is elaborated at first in conjunction with the accompanying drawings.
As shown in Figure 1, Fig. 1 is the schematic flow sheet of the method for the invention, specifically can comprise the steps:
Step 101: secure gateway cluster elects one of them as main security gateway in advance in a plurality of security gateway equipment, and other are as backup secure; Be exactly specifically, owing to will realize that virus scan (AV) flow carries out load-balancing function in secure gateway cluster, and support the transparent access upstream and downstream of secure gateway cluster network environment, secure gateway cluster must elect the interaction process that a main security gateway is responsible for carrying out with the upstream and downstream network environment flow in inside, only communicating by letter with main security gateway as backup secure of other keeps transparent relation with the upstream and downstream environment;
Wherein, election process specifically comprises: secure gateway cluster is selected main security gateway and backup secure according to the priority facility of setting, and what priority was high is main security gateway, and all the other are backup secure.Simultaneously can carry out weight setting to each monitor-interface of security gateway, the availability of big more this interface of representative of weights is high more, under the situation of priority facility unanimity, secure gateway cluster can carry out the election of main security gateway according to different interface weights;
Step 102: main security gateway is discerned the data flow that receives, and identifies the data flow that need kill virus, and sends on its selected backup secure according to the data flow that the predetermined load balance policy is killed virus needs; Be exactly specifically, after entering main security gateway, packet at first carries out the safety regulation coupling, comprise five-tuple attribute specification in the safety regulation, also include simultaneously the Killing Tactics that need carry out packet in the safety regulation the IP message that meets ICP/IP protocol in the packet.Packet is then no longer proceeded the coupling of other safety regulations after having mated a safety regulation, the security strategy that is complementary can be carried out data flow and connection table thereof that anti-virus handles to needs and be carried out mark; Which be sent on the backup secure in the cluster by inquiry cluster slip condition database and dynamic load leveling strategy specified data bag then, heart beat interface by the secure gateway cluster special use sends to corresponding backup secure with packet encapsulation; Secure gateway cluster slip condition database data record the state information of whole cluster, state information comprises the cpu busy percentage of each member device in the cluster, memory usage, linking number size, interface status information, priority facility information, virus base information etc.After the connection table is labeled, all subsequent packets that mate this connection all can be sent to identical backup secure by main security gateway and handle, when carrying out flow load balance, guarantee that the packet between the same stream is assigned on the same backup secure, guarantee the consistency of service and data;
Step 103: the data flow that the needs that backup secure will receive the are killed virus processing of killing virus, and send to main security gateway after will being packaged into packet through the data flow that virus killing is handled; Be exactly specifically, after backup secure receives the packet that the heartbeat oral instructions bring, packet is carried out carrying out after the decapsulation virus scan handle, and the flow after the virus scan (AV) is encapsulated the heartbeat mouth of back by backup secure again flow is sent it back main security gateway;
Step 104: main security gateway receive that backup secure sends behind the packet that virus killing is handled, packet is carried out decapsulation, by the normal process flow process packet is transmitted then.
The method of the invention also comprises:
(device hardware fault after secure gateway cluster detects main security gateway generation abnormal conditions cisco unity malfunction, the monitor-interface fault, the monitoring software fault), can carry out the migration work of main security gateway at the secure gateway cluster equipment room according to priority algorithm; After the main security gateway migration, new main security gateway is taken over the external all functions of whole secure gateway cluster, is responsible for the flow that receives is carried out the work of load balancing according to the secure gateway cluster slip condition database simultaneously.
And, main security gateway is monitored other equipment states in the cluster in real time, after backup secure loses efficacy, can adjust the load balancing strategy in real time, this backup secure was shielded, and other equipment in the cluster were transferred in the work of this backup secure; Be exactly specifically, in case main security gateway detects the backup secure that inefficacy is arranged in the cluster, can be immediately with its shielding, and the secure gateway cluster slip condition database of other renewal of the equipment this locality in the notice secure gateway cluster, make its computing that no longer participates in cluster and load balancing, and other equipment in the cluster are transferred in work; And if the equipment that main security gateway detects in the cluster temporarily can't be worked, then detect again twice, unless all this equipment failure is just thought in failure, thereby guarantee can not carry out error masking to it, thereby cause interrupting the normal efficient that reduces whole secure gateway cluster that connects because separate unit security gateway equipment is temporarily busy.
Other backup nodes in the secure gateway cluster are except the flow of handling main security gateway distribution, also can carry out internal state with other equipment detects, by monitoring the operation conditions of main security gateway, guarantee that each equipment in the cluster all has a unified secure gateway cluster slip condition database, can when main security gateway lost efficacy, carry out new main security gateway election at once, avoid main security gateway Single Point of Faliure.
In the present invention, secure gateway cluster load balancing strategy can be RR (Round Robin, poll) algorithm, WRR (Weight Round Robin, weight poll) algorithm or DRR (Dynamic RoundRobin, dynamic poll) algorithm specifies as follows:

WRR algorithm: the notion that on the basis of polling algorithm, has added weight, can add a weighted value for each equipment in the cluster, when system carries out polling algorithm, can judge the different position of node in the cluster, thereby distribute corresponding flow according to different weighted values.Can set different weights according to the different disposal ability of distinct device, the equipment that disposal ability is high can be assigned to more flow.
DRR algorithm: because network traffics are distributed and the uncertainty of security gateway equipment working state, the static equilibrium algorithm can not be adjusted flow according to the state of load and equipment itself, can not guarantee real load balancing in essence, at this moment will adopt the scheme of dynamic load leveling.The slip condition database meeting regular update of whole secure gateway cluster, when main security gateway carries out data load balance, can dynamically adjust load-balancing mechanism according to the cluster slip condition database, after having detected a device processes ability drop or cisco unity malfunction, can reduce the flow be sent to this equipment, on unnecessary flow load balance other equipment in the cluster.Each equipment in the secure gateway cluster all can be set up a unified cluster slip condition database.This database includes the connection state information of each equipment in the secure gateway cluster, interface status information, CPU state information, internal storage state information, equipment weight information etc.The state information of each cluster device is pushed in the secure gateway cluster automatically, the cluster status data library information of other equipment meeting real-time update oneself after receiving the state information of other equipment in the cluster.Each node in the secure gateway cluster is formed the group system of backup mutually of monitoring mutually, realizes the consistency of cluster internal data.
The secure gateway cluster slip condition database need be safeguarded two tables, one is sender-table, one is recipient's table, data show that corresponding secure gateway cluster node load need move task greater than its threshold value in the sender-table, and record shows that the corresponding node load can accept new task less than its threshold value in the recipient table.Content in every table is carried out real-time update by the state information between cluster, guarantees that the main security gateway in the secure gateway cluster can carry out the dynamic load leveling of flow according to the real time information in the table.
Dynamic polling algorithm no longer simply travels through each equipment in the cluster or carries out the distribution of load according to the weighted value of static state, can be dynamically adapted to the flow of respective nodes according to the operating state of different nodes, after a node processing ability drop, can loading on other available devices with flow dynamics.
