ADVANCED TELECOMMUNICATIONS COMPUTING ARCHITECTURE DATA EXCHANGE SYSTEM, EXCHANGE BOARD AND DATA EXCHANGE METHOD

摘要

Embodiments of the present invention disclose an ATCA data exchange system, an exchange board and a data exchange method. The ATCA data exchange system includes: a backboard, at least one exchange board and at least one service board. The exchange board includes at least one Fabric port group, and each Fabric port group is connected to a service board through the backboard to form a first exchange channel for broadband service data exchange, where the Fabric port group includes four difference sending and receiving port pairs, and each difference sending and receiving port pair includes a pair of difference receiving ports and a pair of difference sending ports. A connector 20 in the Fabric interface of the exchange board includes at least one difference sending and receiving port pair, and each difference sending and receiving port pair is connected to a service board through the backboard to form a second exchange channel that is independent of the first exchange channel, for narrowband service data exchange that is independent of the broadband data exchange through the second exchange channel separately. Through the embodiments of the present invention, processing of narrowband data is simplified, and time delay is decreased.
