Problems solved by technology

[0006] Because in the switching architecture of one cabinet and multiple frames, a switching board needs to be installed in each ATCA frame (for example, two switching boards are required when using a dual-star switching architecture), and the switching board includes switching units, CPUs and other units, and the cost is relatively high; However, when the switching bandwidth is not required, the processing capacity of the switching board does not need to be very high. Therefore, configuring the switching board in this case will waste resources and increase the manufacturing cost.

Abstract

The embodiment of the invention discloses an ATCA (Advanced Telecommunications Computing Architecture) exchange system, a method and a communication device, wherein the system comprises a main exchange frame and a secondary exchange frame. The main exchange frame comprises a first node board and a hub board; the secondary exchange frame comprises a second node board and an I / O (Input / Output) switch board; the I / O switch board comprises a switch interface and is connected with the second node board through the switch interface in the secondary exchange frame; the I / O switch board is connected with the hub board through the switch interface by an external communication link, thus when needing exchange, the second node board data reaches the hub board through the I / O switch board and is exchanged by the hub board. In the embodiment of the invention, the I / O switch board is arranged in the secondary exchange frame, the data is switched to the hub board of the main exchange frame by using the I / O switch board, and the data is exchanged by the hub board of the main exchange frame, thus the exchange frame does not need to be arranged in each frame, and the production cost is reduced.

Description
