ADVANCED TELECOMMUNICATIONS COMPUTING ARCHITECTURE EXCHANGE SYSTEM, ADVANCED TELECOMMUNICATIONS COMPUTING ARCHITECTURE EXCHANGE METHOD, AND COMMUNICATION APPARATUS

摘要

An ATCA exchange system is disclosed according to the embodiments of the present invention. The ATCA exchange system includes: a master exchange shelf, including a first node board and a hub board; and a slave exchange shelf, including a second node board and an I/O transfer board. The I/O transfer board includes an exchange interface, and in the slave exchange shelf, the I/O transfer board is connected to the second node board through the exchange interface. The I/O transfer board is connected to the hub board by using an external communication link through the exchange interface, so that data of the second node board reaches the hub board through the I/O transfer board when the data needs to be exchanged, so as to complete data exchange through the hub board. According to the embodiments of the present invention, the manufacturing cost can be reduced.
