Embodiment Construction

[0027] As shown in FIG. 3 , in the first embodiment of the switching structure for extending the switching bandwidth of ATCA / ATCA 300 of the present invention, there are 14 node boards 31 and 2 switching boards 32 in the ATCA / ATCA 300 system configuration. The switch interface (fabric interface) of the second zone (zone 2) of the backplane includes 4 connectors, namely P20, P21, P22, and P23, which provide up to 15 switch channels to interconnect with other boards.

[0028]In this embodiment, the node board 31 includes a service processing module 311 , an uplink processing module 312 and a downlink processing module 313 , wherein the uplink processing module 312 and the downlink processing module 313 are respectively connected to the service processing module 311 . The uplink processing module 312 is used for data scheduling and evenly distributes the data to each switch board 32 , and the downlink processing module 313 receives the data of each switch board 32 and completes da...

Abstract

In Said ATCA / ATCA 300 system, there are multi node plates and multi exchange plates; said node plates and exchange plates are interconnected via the exchange interface at second region of the backboard; each node plate comprises a service process module, and a uplink processing module and a downlink processing module both respectively connected to the service processing module; said uplink processing module is used for scheduling data and evenly transmitting data to each exchange plate; said downlink processing module is used for receiving the data from each exchange plate and completing the data convergence and data in-sequence recombination.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and system for extending the switching bandwidth in ATCA / ATCA 300. Background technique [0002] ATCA (Advanced Telecommunications Computing Architecture, Advanced Telecommunications Computing Architecture) is an open industry standard framework (standard is PICMG 3.0) formulated and developed by PICMG (PCI Industrial Computer Manufacturers Group, PCI Industrial Computer Manufacturers Association), positioned as a communication device and a computing server General hardware platform technology, including chassis structure, power supply, heat dissipation, single board structure, backplane interconnection topology, system management, and switching network recommendations. ATCA is suitable for 600mm deep cabinets. In order to meet the application requirements of 300mm deep cabinets, PICMG has also formulated the platform architecture standard of ATCA300 (t...
