Abstract
The invention provides a method and a device for switching equipment, and a server. The method comprises the following steps of monitoring a change in an amount of active links in a downlink LACP (Link Aggregation Control Protocol) link of each router to obtain a monitoring result; adjusting the priorities of at least two routers according to indication of the monitoring result, wherein the more the active links of each router are, the higher the priority of the router is; and selecting the router with the highest priority as a current master router from the at least two routers. According to the method and the device for switching equipment, and the server, which are provided by the invention, the master state and the standby state of each router can be switched according to the bandwidth of the downlink LACP link, so that the router with the larger bandwidth in the downlink LACP link becomes the master router.
Description
Technical field
The present invention relates to the Data Interchange Technology of the communications field, particularly relate to a kind of equipment switching method, device and server.
Background technology
VRRP(Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) technology is a kind of equipment redundancy technology.If there is two or more routers in local area network (LAN), the main frame in local area network (LAN) can pass through wherein any router and other network communication.Use VRRP, when the next hop router of main frame breaks down in local area network (LAN), can be replaced by another router timely, thus the continuity of keeping in communication and reliability.Keeper gives the virtual router group number and virtual ip address that in the same network segment, different configuration of routers is identical, makes they compositions virtual router.Virtual flow-line is made up of an active router (Master router) and some backup routers (Backup router), and active router wherein realizes the real function E-Packeted.When active router breaks down, one of them backup router will become new active router, take over its work.
LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) is for the agreement realizing link dynamic aggregation Yu depolymerize, and the effect of polymerization is to improve transmission bandwidth, strengthen system reliability.Under LACP protocol integrated test system, multilink (Member Link) pools the higher logical links of a bandwidth, and this logical links is called convergence group, and this link containing convergence group is LACP link (LAG or Trunk).There is active members link and inactive Member Link two kinds in convergence group, the interface of forwarding data is called Active Interface, and the interface of forwarding data is not called Inactive Interface, the link that Active Interface is corresponding is called active members link, and the link that Inactive Interface is corresponding is called inactive Member Link.
VRRP technology can realize the warm standby function of two center switch in third layer, ensure that another can be got and be with it when a certain center switch breaks down.And LACP was the bandwidth problem of solution two inter-exchanges originally, was used to multilink is held together the technology used as a logical links, but was objectively also serving the effect of link backup.
Often VRRP technology and LACP technical combinations are used in prior art: namely realize device backup with VRRP, realize link backup with LACP.Typical networking as shown in Figure 1, suppose that R1 is default VRRP host apparatus (Master), R2 is VRRP stand-by equipment (Backup), R1, R2 link subscriber exchange under respectively having 2 physical links, article 4, physical link bandwidth is identical, physical link 1,2 and 3,4 aggregates into LACP link respectively, and the LACP link of VRRP signaling between R1, R2 carries.
The deficiencies in the prior art part is: when the physical link 1 of the VRRP networking shown in Fig. 1 interrupts; LACP agreement plays link protection effect; flow is all taken over by physical link 2; logic LACP Link State after binding is normal; even if now VRRP Equipments Setting has watchdog logic LACP Link State, VRRP also can not carry out active-standby switch, and R1 is still primary route device; now user is larger to the available bandwidth resources of R2, but cannot use.
