1. A computer implemented method for establishing a redundant channel from an application to a peer data processing system, the computer implemented method comprising:

  • receiving, by a data processing system, a communication channel status corresponding to an application, wherein the application has a first channel using local access across a first physical conduit to a first switch, wherein the communication channel status is, in part, an interrupt;

    determining whether the redundant channel is present, wherein the redundant channel is configured to use a second physical conduit distinct from the first physical conduit for traffic of the application;

    responsive to a determination that the redundant channel is present, determining whether the redundant channel is configured to use the second physical conduit as local access to a redundant switch, wherein the redundant switch is not the first switch;

    responsive to a determination that the redundant channel is configured to use the second physical conduit, updating a communication channel list to include at least one attribute of the redundant channel, wherein the communication channel list is resident in the data processing system;

    responsive to a determination that the redundant channel is present, determining that the first channel is timed-out based on an acknowledgment message failing to arrive within a time-out period, wherein such a determination is performed by the data processing system at a kernel level; and

    responsive to a determination that the first channel is timed-out, routing traffic of the application over the second physical conduit based on the communication channel list.
