Abstract
A first remote memory access link is established between a first communications interface card on the first computing device and a second communications interface card on the second computing device. In response to an error associated with the first remote memory access link, messages are copied from a segmented queue associated with the first communications interface card to a segmented queue associated with a third communications interface card on the first computing device. A second remote memory access link between the third communications interface card and a fourth communications interface card is activated on the second computing device, and messages are resent from the segmented queue associated with the third communications interface card to the fourth communications interface card through the second remote memory access link. The second computing device discards duplicate received messages, if any.
