Abstract
A first network device implements a method for the secure exchange of data in a network. The network also includes a second network device and a remote device. The method includes establishing an indirect path to the remote device and pre-negotiating first security parameters with the remote device over the indirect path using a network layer protocol, when the second network device has an active first data link. The method further includes establishing an active second data link with the remote device and exchanging first data with the remote device over the active second data link using the first security parameters, when the first data link becomes inactive.
