1. A protection switching device comprising:
a first connector configured to connect a first host device to the protection switching device, the protection switching device being separate from the first host device;
a second connector configured to connect the protection switching device over a first link to a first switch among a plurality of switches coupled to a second host device;
a third connector configured to connect the protection switching device over a second link to a second switch among the plurality of switches coupled to the second host device; and
protection switching circuitry configured to selectively connect the first host device to the first link to establish a communications connection to transfer a first portion of data between the first host device and the second host device via the first switch, to selectively modify content of a second portion of the data to enable transfer of the second portion of the data using the second link, to selectively connect the first host device to the second link to maintain the communications connection, and, based on the modified content, to transfer the second portion of the data between the first host device and the second host device via the second switch.
