ATCA board card

Abstract

The invention discloses an ATCA (Advanced Telecom Complex Architecture) board card, which comprises a service sub-board and an RTM (Register Transport Module) card sub-board connected with the service sub-board, the service sub-board comprises a CPU (Central Processing Unit) module, a network acceleration module connected with the CPU module, a PCIE (Peripheral Component Interface Express) switching module, a gigabit Ethernet module and a CPLD (Complex Programmable Logic Device) module, and the RTM card sub-board comprises an FPGA (Field Programmable Gate Array) table look-up module, a 10Gbps interface module connected with the FPGA table look-up module and an RTM interface connector. The ATCA board card follows the ATCA standard specification and integrates the service sub-board and the RTM card sub-board, so that the expansibility of the ATCA board card and the RTM card is improved, and the development and maintenance cost of the ATCA is reduced.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to an ATCA board. Background technique [0002] With the development of communication technology and the expansion of application fields, higher requirements are put forward for the capacity and reliability of communication equipment. Among them, communication equipment with large data and large traffic mostly adopts the ATCA architecture. [0003] Advanced Telecommunications Computing Architecture (ATCA) is a new standard developed by PCI Industrial Computers Manufacturing Group (PICMG). The ATCA hardware specification includes chassis management controllers, platform cooling systems, switching boards, and service boards. The core of the service board is the CPU processor. [0004] Currently on the market mainly include: foreign Intel Xeon series, Cavium company CN78xx series, Broadcom's XLPxx series, Mellanox company's NPS400 series. However, with the emphasis on national...

AI Technical Summary

Problems solved by technology

[0005] If you use foreign ATCA boards for a long time, on the one hand, you need a lot of money to purchase, and it is easy to be monopolized and you need to pay more money, which will greatly increase the production and operation costs of Chinese enterprises, and there are additional restrictions. etc., which greatly increases the operating cost and operating risk for the enterprise
