Abstract
A distributed PCIe adapted to support a hot-plug process triggered by any change in a status of a distributed link, comprises an upstream bus unit including a first bridge connected to a root component and adapted to maintain a first configuration space and a copy of a second configuration space, the first configuration space bridge includes at least hot-plug registers specifying at least capabilities and status of a slot of the first bridge; and a second bridge connected to an endpoint component and adapted to maintain the second configuration space, the second configuration space includes at least hot-plug registers specifying at least capabilities and status of a slot of the second bridge.
