Problems solved by technology

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: the prior art cannot implement cross-computer room clusters using the DR mode for load balancing without third-party development, and the DR mode cannot use different network segments for polling and forwarding. It is difficult for the scheduler to break through the forwarding rate limit of its own network hardware

Embodiment 1

[0023] figure 2 It is a flow chart of an open shortest path first OSPF cross-network balanced forwarding method of this embodiment, as figure 2 As shown, it includes the following steps:

[0024] Step 110: the routing device receives the parsed user request information;

[0025] Step 120: According to the OSPF protocol, the user request information and the port information of the routing device, the routing device polls and forwards data to each dispatching server in different network segments, and allocates the physical link between the routing device and each dispatching server to different on the scheduling server in the network segment, and determine the target scheduling server corresponding to the target physical link;

[0026] Step 130: the target scheduling server forwards the user request information to the backend server cluster in the same intranet;

[0027] Step 140: The backend server cluster returns the result to the user.

[0028] The following combination...

Embodiment 2

[0049] This embodiment provides an open shortest path first OSPF cross-network balanced forwarding system to realize the foregoing method, such as image 3 As shown, the system includes:

[0050] The routing device 210 is used to receive the resolved user request information, according to the OSPF protocol, the user request information and the port information of the routing device, poll and forward data to each scheduling server in different network segments, and connect the routing device with each scheduling server. The physical links between servers are assigned to scheduling servers in different network segments, and the target scheduling server corresponding to the target physical link is determined;

[0051] A plurality of scheduling servers 220 across network segments are used to forward requests to the back-end server clusters in the same intranet after being determined as the target scheduling server;

[0052] A plurality of backend server clusters 230, each backend...

Abstract

An embodiment of the invention provides an open shortest path first (OSPF) over-network balanced forwarding method and an OSPF over-network balanced forwarding system. The OSPF over-network balanced forwarding method comprises the steps of receiving analyzed user request information by router equipment; according to an OSPF protocol, the user request information and port information of the router equipment, performing data polling forwarding on scheduling servers in different network segments by the router equipment, allocating physical links between the router equipment and the scheduling servers to the scheduling servers in different network segments, and determining a target scheduling server which corresponds with a target physical link; forwarding the user request information by the target scheduling server to a back-end server cluster in a same internal network by the target scheduling server; and returning a result to the user by the back-end server cluster. The OSPF over-network balanced forwarding method has advantages of continuously improving concurrent capacity of a load balancing system, keeping high available capacity, improving forwarding efficiency and facilitating transverse over-network-segment expansion.

Description

technical field [0001] The invention relates to a three-layer switch OSPF (OpenShortestPathFirst, open shortest path first), in particular to an open shortest path first OSPF cross-network balanced forwarding method and system. Background technique [0002] The current service cluster deployment methods include the following: a single software composition, the more common one is keepalived (which is a software similar to layer3, 4&7 switching mechanism) + LVS (LinuxVirtualServer, Linux virtual server) or heartbeat (which is a Linux- An integral part of the HA project, which realizes a high availability cluster system) + LVS composition; a single hardware composition, the more common one is F5 or other load balancing equipment, and the network cable is directly connected to the equipment; the combination of software and hardware, load balancing hardware Equipment plus self-developed software support. If the above method uses DR (DirectRouting, direct routing) mode, only the ...
