Fig. 3 is a flowchart of a method for determining a set of load balancing devices according to an embodiment of the present disclosure, which specifically includes the following steps:
step 301, two sets of load balancing devices in a master-slave relationship in a load balancing access group are corresponding to two service types, wherein the two service types include a first service and a second service.
In this step, different traffic partitions manage different traffic, and when the load balancing resource pool in this specification is applied to a plurality of different traffic partitions, different load balancing devices in the load balancing resource pool need to serve different traffic types. In some embodiments of the present disclosure, there are 4 load balancing devices in the two sets of load balancing devices in a master-slave relationship in the access group, which collectively correspond to two service types.
And if the first service type is the service A, the second service type is the service B. The two sets of load balancing devices in the load balancing access group with the primary-backup relationship can be the first set of load balancing devices and the second set of load balancing devices.
In step 302, a primary load balancing device in a set of load balancing devices in the load balancing access group is a primary device of the first service, and a standby load balancing device is a standby device of the second service.
In the embodiment of the present disclosure, if the load balancing access group in this step is the load balancing access group 1, one set of load balancing devices in the load balancing access group 1 is a first set of load balancing devices, where the main load balancing device is a main device of the first service a, referred to as a main, and the standby load balancing device is a standby device of the second service B, referred to as a standby. Thus, the A master and the B slave form a first set of load balancing equipment.
In step 303, a master load balancing device in another set of load balancing devices in the load balancing access group is a master device of the second service, and a standby load balancing device is a standby device of the first service a. Corresponding to step 202, one set of load balancing devices in the load balancing access group 1 except the first set of load balancing devices is a second set of load balancing devices, wherein the main load balancing device is a main device of the second service B, called B main, and the standby load balancing device is a standby device of the first service a, called a standby. Thus, B master, A slave form a second set of load balancing devices, as shown in FIG. 7.
In some embodiments of the present description, the set of load balancing devices in step 202 may be referred to as a first set of load balancing devices, the first set of load balancing devices being a primary set of devices accessing a first service a and a backup set of devices accessing a second service B. Under normal conditions, the default traffic path for accessing the first traffic is: the core switch goes to the plane one access layer switch, from the plane one access layer switch to the primary load balancing device in the first set of load balancing devices. The default traffic path for accessing the second traffic is: the core switch goes to the access layer switch of the second plane, goes from the access layer switch of the second plane to the main load balancing device in the second set of load balancing devices. The second set of load balancing equipment is determined to be standby equipment accessing the first service and main equipment accessing the second service; and forming a load balancing access group by the first set of load balancing equipment and the second set of load balancing access, wherein the load balancing access group is the first load balancing access group.
Fig. 4 is a flowchart of a method for determining another load balancing access group according to an embodiment of the present disclosure, which specifically includes the following steps:
in step 401, two sets of load balancing devices in a master-slave relationship in another load balancing access group are corresponding to two other services except the first service and the second service, where the two other services are a third service and a fourth service respectively. In the present embodiment, another load balancing group is referred to as load balancing group 2 in fig. 3. Corresponding to the embodiment in fig. 3, the third service in this step may be service C, and the fourth service may be service D.
Step 402, a primary load balancing device in a set of load balancing devices in the other load balancing access group is a primary device of the third service, and a standby load balancing device is a standby device of the fourth service.
In the embodiment of the present disclosure, if the load balancing access group in this step is the load balancing access group 2, one set of load balancing devices in the load balancing access group 2 is the 3 rd set of load balancing devices, where the primary load balancing device is the primary device of the third service C, referred to as C primary, and the standby load balancing device is the standby device of the fourth service D, referred to as D standby. Thus, the C master and the D slave form a third set of load balancing equipment.
Step 403, a primary load balancing device in another set of load balancing devices in the another load balancing access group is a standby device of the third service, the standby load balancing device is a primary device of the fourth service, and the another load balancing access group is a second load balancing access group.
Corresponding to step 402, one set of load balancing devices except for the 3 rd set of load balancing devices in the load balancing access group 2 is the 4 th set of load balancing devices, wherein the main load balancing device is the main device of the fourth service D, called D main, and the standby load balancing device is the standby device of the third service C, called C standby. Thus, dmaster, cslave form a second set of load balancing devices. As shown in fig. 7. The load balancing resource pool has the capability of transverse expansion, and can expand a plurality of load balancing access groups and a plurality of load balancing devices according to service demands so as to correspond to more service groups. Furthermore, the load balancing resource pool disclosed by the specification can be compatible with various product brands, improves performance capacity and flexibility of network resource service, and supports multi-cluster deployment and flexible capacity expansion.
Fig. 5 is a flowchart of a method for communicating between a planar environment and a load balancing device according to an embodiment of the present disclosure, which specifically includes the following steps:
step 501, an access layer switch in a first plane environment of two plane environments is respectively connected with a first set of load balancing equipment in a first load balancing access group and a second set of load balancing equipment in a second load balancing access group. In this specification, a dual-plane environment is constructed by using a core switch, and the dual-plane environment includes a first plane environment and a second plane environment, respectively.
In the embodiment of the present specification, the first plane environment and the second plane environment have the same configuration policy, and the difference between the first plane environment and the second plane environment is the difference in load balancing devices to which the access group switch in each plane is communicatively connected. AS shown in fig. 7, the first plane environment includes access layer switches AS1 and AS2, where the access layer switches AS1 and AS2 are respectively connected to a first set of load balancing devices in the load balancing access group 1, and simultaneously connect the access layer switches in the first plane environment in the two plane environments to a first set of load balancing devices in the first load balancing access group and a second set of load balancing devices in the second load balancing access group.
Step 502, connecting an access layer switch in a second plane environment of the two plane environments with a second set of load balancing equipment in the first load balancing access group and a first set of load balancing equipment in the second load balancing access group respectively.
AS shown in fig. 7, the second plane environment includes access layer switches AS3 and AS4, where the access layer switches AS3 and AS4 are respectively connected to a second set of load balancing devices in the load balancing access group 1, and the access layer switches AS3 and AS4 are connected to a first set of load balancing devices in the second load balancing access group.
Fig. 6 is a flowchart of a method for setting a route for a load balancing device and a switch according to an embodiment of the present disclosure, which specifically includes the following steps:
step 601, running a static routing protocol between the load balancing device and the access layer switch. In this step, a static route is run between the load balancing and the access stratum AS switch, and a binding network quality analysis (NQA, (Network Quality Analyzer) detects the floating address of the access stratum switch load balancing device, and the static route is redistributed into the BGP routing domain on the access stratum switch.
Step 602, running a dynamic routing protocol between the access layer switch and the core switch. Specifically, an eBGP dynamic routing protocol is operated between an access layer switch and a core switch, and Route-Policy is deployed when BGP peer is arranged on the core switch. The running dynamic routing protocol can automatically calculate the route for the switch of the access layer, so that the control is convenient.
In other embodiments of the present description, the core switch is communicatively coupled to a data network switching core (DCN), a management network switching core (DCNM). Specifically, an OSPF routing protocol is run between the core switch and the data network switch core, an EBGP routing protocol is run between the core switch and the management network switch core, and default routes of the service network segments are respectively sent to the switch core areas by introducing OSPF and BGP. Further, the core switch is also communicatively coupled to a routing switch (RT). Specifically, the two core switches are respectively in communication connection with two routing switches, and the two routing switches are connected with C0. And an OSPF routing protocol is operated between the routing switch and C0, and the resource pool service network segment points to the firewall and the bypass route to be introduced into OSPF.
In the present specification, when a certain set of load balancing equipment has an overall fault, the load balancing resource pool in the present specification switches a default traffic path, updates a dual-machine fault traffic path, as follows:
when the 1 st set of load balancing equipment fails wholly, the priority route of the first service A issued by the 2 nd set of load balancing equipment takes effect, and if the first service A is accessed, the updated flow path is as follows: core switch to plane 2 access layer switch, plane 2 access layer switch to set 2 load balancing device.
When the whole of the load balancing equipment of the 2 nd set fails, the suboptimal route of the second service B issued by the load balancing equipment of the 1 st set takes effect, and if the second service B is accessed, the updated flow path is as follows: core switch to plane 1 access layer switch, plane 1 access layer switch to set 1 load balancing device. The embodiment of the specification can cope with the risk of fault domain expansion after centralized deployment, and realize park-level biplane. When a single plane fault or a load balancing main and standby double-machine fault occurs, plane switching connection can be realized in the park without implementing park-level switching.
