For a better understanding of the present invention, existing to DHCP(DynamicHostConfigurationProtocol, DHCP) be described:
DHCP is from BOOTP(BootstrapProtocol, Bootstrap Protocol) develop, adopt customer end/server mode as shown in Figure 4, for dhcp client dynamic IP address allocation and other relevant information.Wherein, under comprising the scene of the DHCP relay being generally the network equipment such as router or three-tier switch in a network, the process that dhcp client is retrieved as the default gateway ip address of its dynamic assignment is as follows:
1, discovery phase: dhcp client sends DHCPDiscover broadcasting packet to search Dynamic Host Configuration Protocol server to network, and DHCP relay receives this DHCPDiscover message and is transmitted to Dynamic Host Configuration Protocol server;
2, the stage is provided: after Dynamic Host Configuration Protocol server receives DHCPDiscover message, from oneself address pool, select an IP address be not assigned with and then send to this dhcp client the DHCPOffer message comprising this IP address and other configuration information, this DHCPOffer message repeating is given this dhcp client by DHCP relay;
3, the choice phase: if multiple stage Dynamic Host Configuration Protocol server sends DHCPOffer message to this dhcp client, this dhcp client receives only first DHCPOffer message and then sends DHCPRequest broadcasting packet to network, to ask the Dynamic Host Configuration Protocol server as first DHCPOffer message sender to be its distributing IP address, forward this DHCPRequest message by DHCP relay;
4, the stage of recognition: after the Dynamic Host Configuration Protocol server as first DHCPOffer message sender receives this DHCPRequest message, send the DHCPACK message comprising IP address that it provides and other configuration information to this dhcp client, forward this DHCPACK message by DHCP relay; And
5, configuration phase: this dhcp client configures its gateway address according to message content after receiving this DHCPACK message.
The various DHCP message of above-mentioned such as DHCPDiscover message, DHCPOffer message, DHCPRequest message, DHCPACK message etc. are UDP(UserDatagramProtocol, User Datagram Protocol) message.
Namely gateway configuration is realized based on DHCP according to gateway configuration method, gateway device and network system that the embodiment of the present invention provides.As shown in Figure 5, comprise according to the gateway configuration method of the embodiment of the present invention:
S1, is belonging to multiple gateway device deploy one management backup group of a network segment, comprises at least two gateway devices and by the priority determination main management gateway of comprised gateway device and standby management gateway to make described management backup group;
S2, in described multiple gateway device deploy at least two service backup groups, be assigned a virtual ip address separately to make described service backup group, comprise at least two gateway devices and by the priority determination main business gateway of comprised gateway device and standby Service Gateway;
S3, the DHCPDiscover message that described multiple gateway device Receiving Host sends, and only as the gateway device (hereinafter referred to as main management gateway device) of described main management gateway as DHCP relay by described DHCPDiscover message repeating to Dynamic Host Configuration Protocol server, and other gateway device directly can abandon received DHCPDiscover message;
S4, described main management gateway device receives the DHCPOffer message that described dhcp server response sends in described DHCPDiscover message, the virtual ip address of the specified services backup group at least two service backup groups described in the gateway field in described DHCPOffer message is extended this as, and will the DHCPOffer message repeating after gateway field be filled in described main frame;
S5, described main management gateway device receives the DHCPRequest message that described response of host sends in described DHCPOffer message, and forwards it to described Dynamic Host Configuration Protocol server; And
S6, described main management gateway device receives the DHCPACK message that described dhcp server response sends in described DHCPRequest message, gateway field in described DHCPACK message is extended this as the virtual ip address of described specified services backup group, and give described main frame by the DHCPACK message repeating after filling in, with main frame described in instruction, described specified services backup group is configured to its default gateway.
In a kind of possible implementation, based on VRRP agreement at described multiple gateway device deploy backup group.Such as, described multiple gateway device consults the priority in the described management backup group of each leisure by VRRP protocol massages.In addition, based on VRRP agreement in described multiple gateway device deploy multiple service backup group time, the priority in each described service backup group of each leisure of described multiple gateway device can be set, to guarantee to realize sharing business load on all entity gateway devices corresponding with the virtual gateway of each service backup group according to the manual configuration of operator.
In a kind of possible implementation, in S4, described main management gateway device select based on the pre-defined algorithm of such as hash algorithm described in one of at least two service backup groups as described specified services backup group.Like this, as long as ensure that the virtual ip address distributing to the default gateway of main frame is by the distribution of certain algorithm, to the gateway that different host assignment is different, can ensure that service traffics realize load balancing between different gateway.
In addition, after being configured with the virtual ip address of the default gateway of particular host by execution S3 ~ S6, if there is service traffics demand in this main frame, this main frame usually by first broadcast transmission ARP(AddressResolutionProtocol, address resolution protocol) request.In this case, only respond this ARP as the gateway device (hereinafter referred to as main business gateway device) of main business gateway in specified services backup group to ask, forwarded by this main business gateway device to make the follow-up business flow of this main frame, wherein, the virtual ip address of described specified services backup group is configured as the default gateway address of this main frame.
And, it should be noted that: 1) first perform S1 although Fig. 5 illustrates, perform S2 again, but those skilled in the art should be able to understand, also can first perform S2, perform S1 again, perform S1, S2, as long as a management backup group and at least two service backup groups can be set up on the multiple gateway devices belonging to a network segment even simultaneously; And 2) although Fig. 5 illustrates perform S3 ~ S6 once, but those skilled in the art should be able to understand, on the basis establishing a management backup group and at least two service backup groups, can S3 ~ S6 be repeated completely, automatically configure to carry out default gateway to any main frame in this network segment.
By managing backup group in multiple gateway device deploy and only managing the function can bearing DHCP relay in backup group as the gateway device of main management gateway, even if under the scene that host number is larger, the gateway configuration method provided according to the embodiment of the present invention also can based on the default gateway address of the automatic configure host of DHCP, not only to realize load balancing but also mutually back up between different entity gateway devices.
Fig. 6 illustrates the schematic diagram of an application scenarios of the gateway configuration method according to the embodiment of the present invention.As shown in Figure 6, router RT1, RT2 as gateway device of belonging to the same network segment (such as, belonging to same VLAN) are connected with main frame 1, main frame 2, main frame 3 via switch, and all can communicate with Dynamic Host Configuration Protocol server.Wherein, assuming that the real IP address of RT1, RT2 is respectively 100.1.1.1,100.1.1.2.
First, S1, S2 by performing Fig. 5 set up a management backup group as shown in the table and two service backup groups on RT1, RT2.
As shown above, manage backup group and can not have virtual ip address.RT1, RT2 priority in management backup group is respectively 200,150.Therefore, the RT1 that management backup group medium priority is high is main management gateway device, and the RT2 that management backup group medium priority is low is standby management gateway equipment.Wherein, standby management gateway equipment can be promoted to main management gateway device when main management gateway device failure, and is reduced to standby management gateway equipment when former main management gateway device failure is recovered.
Service backup group 1 is assigned virtual ip address 100.1.1.3.RT1, RT2 priority in management backup group is respectively 120,100.Therefore, being the main business gateway device of service backup group 1 at the RT1 that service backup group 1 medium priority is higher, is the standby Service Gateway equipment of service backup group 1 at the RT2 that service backup group 1 medium priority is lower.Wherein, standby Service Gateway equipment can be promoted to main business gateway device when main business gateway device failure, and is reduced to standby Service Gateway equipment when former main business gateway device failure is recovered.
Service backup group 2 is assigned virtual ip address 100.1.1.4.RT1, RT2 priority in management backup group is respectively 100,120.Therefore, being the standby Service Gateway equipment of service backup group 2 at the RT1 that service backup group 2 medium priority is lower, is the main business gateway device of service backup group 2 at the RT2 that service backup group 2 medium priority is higher.
It should be noted that, although represent that priority as above with numeric form, those skilled in the art should be able to understand, the setting means of priority should be not limited thereto, as long as can according to the active and standby relation of priority determination entity gateway device in backup group.In addition, the priority of gateway device in management backup group independently can be determined by VRRP message negotiation by gateway device; But the priority of gateway device in service backup group, preferably by operator's manual configuration, realizes sharing business load to meet.
Then, on the basis as above establishing management backup group, service backup group 1, service backup group 2, the default gateway of each main frame is configured by performing the S3 ~ S6 shown in Fig. 5.For the default gateway of configure host 1, details are as follows:
S3, when DHCPDiscover message initiated by main frame 1, RT1 and RT2 can receive this DHCPDiscover message, but only have the RT1 as main management gateway device can be used as DHCP relay and forward this DHCPDiscover message to Dynamic Host Configuration Protocol server, and RT2 can select directly to abandon this DHCPDiscover message.
S4, after RT1 is by this DHCPDiscover message repeating to Dynamic Host Configuration Protocol server, Dynamic Host Configuration Protocol server responds DHCPOffer message.After RT1 receives this DHCPOffer message, gateway field in this DHCPOffer message is extended this as the virtual ip address of service backup group 1 or service backup group 2, such as can fill in the virtual ip address 100.1.1.3 of service backup group 1, and by the DHCPOffer message repeating after filling in main frame 1.
After S5, main frame 1 receive this DHCPOffer message, initiate DHCPRequest request.As the RT1 of DHCP relay by this DHCPRequest message repeating to Dynamic Host Configuration Protocol server.
After S6, Dynamic Host Configuration Protocol server receive this DHCPRequest message, reply DHCPACK message.Gateway field in this DHCPACK message is extended this as determined virtual ip address 100.1.1.3 in S4 by the RT1 as DHCP relay, and by the DHCPACK message repeating after filling in main frame 1.After main frame 1 receives this DHCPACK message, confirm the default gateway address using the virtual ip address 100.1.1.3 of service backup group 1 as oneself.
So far, the default gateway configuration of main frame 1 terminates.Subsequently, if when main frame 1 exists business datum demand, by first broadcast transmission ARP request.At this moment, the main business gateway device due to service backup group 1 is RT1, therefore replys this arp reply by RT1, is forwarded by RT1 to make the follow-up business flow of main frame 1.
Similarly, S3 ~ S6 can again be performed with the default gateway of configure host 2.From previous to perform S3 ~ S6 different, for the consideration of load balancing, the gateway field of DHCPOffer message can be extended this as the virtual ip address 100.1.1.4 of service backup group 2 in S4.Like this, the RT2 by the main business gateway device as service backup group 2 responds by the ARP request of follow-up main frame 2, and the service traffics of main frame 2 will be forwarded by RT2.
In addition, according in the above-mentioned gateway configuration method of the embodiment of the present invention, according to the principle of VRRP, the main gateway device (comprising main management gateway device, main business gateway device) of each backup group (comprising management backup group, service backup group) all can with certain cycle, with the mode of multicast other gateway device transmission VRRP message in group, to inform that it exists.The standby gateway device VRRP message that (comprising standby management gateway equipment, standby Service Gateway equipment), real-time listening main gateway device sent, and when not hearing described VRRP message in Preset Time, standby gateway device the highest for priority is promoted to main gateway device.
Tool says it, and when main gateway device normally works, it can send a VRRP multicast message at set intervals, and it is in normal operating conditions to inform standby gateway device.If standby gateway device does not receive the VRRP multicast message from main gateway device for a long time, be then main gateway device by oneself State Transferring.When having multiple stage for gateway device in a backup group, in the manner described above, multiple host exchange will likely be produced.At this moment each main gateway device will the priority of priority in relatively received VRRP multicast message and oneself this locality, if the priority of this locality is less than the priority in VRRP multicast message, be then standby gateway device by the State Transferring of oneself, otherwise keep the state of oneself constant.By such process, standby gateway device the highest for this backup in-group priority can be promoted to the new main gateway device of this backup group, namely achieve the backup functionality of VRRP.
Still for the scene shown in Fig. 6, when RT2 breaks down, be in the service backup group 2 of main business gateway device at RT2, will the VRRP message of RT2 transmission be can not receive as its RT1 for Service Gateway equipment, therefore, RT1 changes the main business gateway device of service backup group 2 into.Once RT2 recovers from fault, because the priority of RT2 in service backup group 2 is higher, then RT2 will become the main business gateway device of service backup group 2 and RT1 will revert to the standby Service Gateway equipment of service backup group 2 again.Therebetween, main frame 2 faced by be the virtual ip address 100.1.1.4 of service backup group 2 all the time, to the active and standby conversion not perception in above-mentioned service backup group 2.
To sum up, according in the above-mentioned gateway configuration method of the embodiment of the present invention, each service backup group keeps higher independence, thus accelerates fault perception, improves the reliability of network system further.
In addition, additionally provide a kind of gateway device according to the embodiment of the present invention, can be applicable to the situation that multiple gateway device belongs to the same network segment.Fig. 7 shows the structured flowchart of this gateway device.As shown in Figure 7, gateway device 700 comprises management group deployment unit 710, service groups deployment unit 720, management gateway performance element 730, wherein:

Service groups deployment unit 720 forms at least two service backup groups jointly for making gateway device 700 and other gateway device 7001 ~ 700n, is assigned a virtual ip address separately, comprises at least two gateway devices and by the priority determination main business gateway of comprised gateway device and standby Service Gateway to make described service backup group.
Management gateway performance element 730 for receive at gateway device 700 main frame 600 send DHCPDiscover message time, if gateway device 700 is defined as main management gateway by management group deployment unit 710, then perform following functions:
By described DHCPDiscover message repeating to Dynamic Host Configuration Protocol server 500;
Receive the DHCPOffer message that Dynamic Host Configuration Protocol server 500 sends in response to described DHCPDiscover message, the virtual ip address of the specified services backup group at least two service backup groups described in the gateway field in described DHCPOffer message is extended this as, and will the DHCPOffer message repeating after gateway field be filled in main frame 600;
The DHCPRequest message that Receiving Host 600 sends in response to described DHCPOffer message, and forward it to Dynamic Host Configuration Protocol server 500; And

In a kind of possible implementation, based on VRRP agreement at the multiple gateway device deploy backup groups comprising gateway device 700 and other gateway device 7001 ~ 700n.Such as, management group deployment unit 710 makes gateway device 700 and the priority in the described management backup group of each leisure of other gateway device 7001 ~ 700n autonomous negotiating by VRRP protocol massages.In addition, based on VRRP agreement in the multiple gateway device deploy comprising gateway device 700 and other gateway device 7001 ~ 700n multiple service backup group time, service groups deployment unit 720 preferably sets the priority of gateway device 700 in each described service backup group according to the manual configuration of operator, to guarantee to realize sharing business load on gateway device 700 with other gateway device 7001 ~ 700n.
In a kind of possible implementation, management gateway function performance element 730 select based on the pre-defined algorithm of such as hash algorithm described in one of at least two service backup groups as described specified services backup group.Like this, as long as ensure that the default gateway ip address distributing to main frame is by the distribution of certain algorithm, namely gives the gateway that different host assignment is different, realizes load balancing with regard to guaranteed service flow between different entities gateway device as far as possible.
In a kind of possible implementation, management gateway function performance element 730 also for, when gateway device 700 receives the DHCPDiscover message of main frame 600 transmission, if gateway device 700 is defined as standby management gateway by management group deployment unit 710, then gateway device 700 is made directly to abandon described DHCPDiscover message.
