Micro general hardware platform system, apparatus for telecommunication and computer, and communication method thereof

Abstract

The invention discloses a MicroTCA system which comprises a first MCH of the MicroTCA system and at least two AMCs, wherein, the first MCH is connected with each AMC; the AMCs are connected with each other; and connecting passages between a second AMC and the first MCH and between the second AMC and the first AMC can serve as back-up passages of the connecting passage between the first AMC and the first MCH. The embodiment of the invention provides an IPMB-L, eliminates SPOF, and provides system reliability. Meanwhile, the invention further discloses a method for the MicroTCA system to achieve communications.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a small-scale telecommunications and computing general hardware platform (MicroTCA) system, device and communication method thereof. Background technique [0002] Micro Telecommunications Computing Architecture (Micro Telecommunications Computing Architecture, Micro is a small telecommunications and computing general hardware platform architecture developed by the PCI Industrial Computer Manufacturers Group (PICMG)). MicroTCA uses AMC (Advanced Mezzanine Card, Advanced Mezzanine Card). Card) to build a system. The AMC that supports hot-plugging can be directly plugged into the backplane of MicroTCA. MicroTCA is mainly positioned in the low-end, cost-sensitive, and requires small physical size telecommunications or computing applications. The main applications include wireless base stations, Routers, media gateways, etc. The basic specification of MicroTCA is MicroTCA.0,...

AI Technical Summary

Problems solved by technology

[0012] When a short-circuit fault occurs, the IPMB-L management bus between MCH1 and AMC1 is short-circuited, and MCH1 cannot manage AMC1

Due to the IPMB-L management and the Y-shaped structure of the bus, the IPMB-L management bus connection between MCH2 and AMC1 will also be suspended. lost

[0013] When fault 2 occurs, the IPMB-L management bus between MCH1 and AMC1, and the IPMB-L management bus between MCH2 and AMC1 cannot work normally, and the management of AMC1 by the system will be lost

[0014] To sum up, because only one IPMI interface is defined on the AMC, there is a single point of failure in the IPMB-L management bus architecture defined by the MicroTCA specification. The occurrence of a single point of failure will cause the system to lose the management of the AMC, and the system cannot manage the AMC. Perform normal configuration and management to reduce system reliability
