Problems solved by technology
Although there is no single point of failure in the control plane link of this solution, its disadvantage is that when two links fail, the communication link between one frame and other frames may be interrupted, for example, when the Ethernet switch board If the port connected to the central Ethernet switch board 41 on 35 fails, and the port connected to the Ethernet switch board 36 on the central Ethernet switch board 42 fails, the communication link between the line card frame and the two central switch frames will be disconnected.
It can be seen that with the existing technology, no matter which implementation scheme is used, the problem of communication disconnection between the line card frame and the central switching frame cannot be avoided, and the reliability is very low. At present, there is an urgent need for a highly reliable router cluster to implement inter-board communication. interconnected implementation

Embodiment Construction
[0036] The basic idea of the present invention is: the Ethernet switching boards in the line card frame are respectively connected with the central Ethernet switching boards in at least two central switching frames.
[0037] What needs to be pointed out here is that the "interconnection" in this article is different from the "interconnection" that only includes physical connections in the usual sense. The relation of realizing the connection will not be described in detail.
[0038] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.
[0039] A device for interconnecting boards in a router cluster, mainly including the following contents:
[0040] The device includes: at least two central switching frames and line card frames, and at least two central switching frames are connected to a central Ethernet switching board. The device also includes: the Ethernet switching boards in the line card f...

The invention discloses a device for interconnecting router cluster middle plates, comprising at least two central exchange frames and a line clamping frame, wherein, central Ethernet switch boards between the at least two central exchange frames are connected; and Ethernet switch boards in the line clamping frame are respectively connected with the central Ethernet switch boards in the at least two central exchange frames. The invention also discloses a method for interconnecting router cluster middle plates, comprising the following steps: connecting the central Ethernet switch boards between the at least two central exchange frames; and respectively connecting the Ethernet switch boards in the line clamping frame with the central Ethernet switch boards in the at least two central exchange frames. The device and the method of the invention can improve reliability, and solve communication broken chain problem between the line clamping frame and the central exchange frame.
Description
technical field [0001] The invention relates to a control plane interconnection technology, in particular to a device and method for inter-board interconnection in a router cluster. Background technique [0002] With the rapid development of Internet technology, new services are constantly emerging, especially the rise of video services represented by peer-to-peer (P2P) and Internet TV (IPTV), which greatly stimulates the demand for bandwidth. , Web browsing and other needs, developed to today's P2P download, video chat, podcast and so on. Whether it is from the application mode or network traffic, earth-shaking changes have taken place. Therefore, network core equipment is facing increasingly severe challenges, especially the extremely high requirements for the capacity and scalability of backbone network core routers. For example, in the telecommunications process of the IP network, high-end core routers are put forward extremely high requirements in terms of capacity, s...
