High-expandability advanced telecom calculating architecture (ATCA) plate based on multi-core network processing unit

Abstract

The invention provides a high-expandability ATCA plate based on a multi-core network processing unit, which is characterized in that: a dual-CPU module is composed of SPI 4.2 bus interfaces in serial connection; a storage module is composed of a nonvolatile memory and a dynamic memory; a PCI-X-to-PCI-E bridging expansion module comprises two PCI-X-to-PCI-E bridge chips, two PCI-E switches and an electronic switch; an AMC module supports one PCI-E interface and four gigabit Ethernet interfaces; a multi-MAC module is gated by one electronic switch to a Fabric channel in a ZONE zone through 2 XAUI interfaces or 2 1Gbps SerDes interfaces; a mass local storage module is in the form of subcard; and the IPMI module is used for the hardware management of the entire ATCA plate and providing perfect management support for the expandability of the PCI-E bus, the AMC module and the multi-MAC module; based on the concept of openness, modularization and standardization of ATCA, the expandability of ATCA service plate and RTM plate is enhanced, the production and maintenance costs of ATCA platform are lowered, and the applicable scope of the service plate is widened.

Description

technical field [0001] The invention belongs to the field of computer and network communication, and in particular relates to a highly scalable ATCA board based on a multi-core network processor. Background technique [0002] Advanced Telecommunications Computing Architecture (ATCA) is a new standard developed by PCI Industrial Computers Manufacturing Group (PICMG). ATCA is an industry-sponsored standard to create a new optimized board and chassis form factor for carrier-grade telecom solutions. ATCA is designed to meet the requirements of next-generation communication applications by providing support for multiple standard switching architectures, and to provide manufacturers with many functions to meet the requirements of demanding users. As a hardware platform standard, ATCA mainly includes chassis and its management controller, platform cooling system, switching boards, and service boards. [0003] Among them, the service board is responsible for the business realizati...
