1. A host bus adapter for implementing a first port of a node on a network of nodes interconnected through an intelligent connection system comprising:
- a transceiver providing a physical interface for the first port; and
a protocol controller that transmits a notification to the intelligent connection system on behalf of a remote second port indicating that the second port may have failed when the second port fails to communicate with the first port.

14. A method for advertising port state changes in a network of nodes interconnected through an intelligent connection system comprising:
-
detecting, by a first port, an interruption in communication with a second port; and
transmitting from the first port to the intelligent connection system a notification of a state port change, wherein the notification identifies the second port as the source of the notification which has experienced the state change. - View Dependent Claims (18, 19, 20, 21, 22, 23)

26. A host bus adapter for implementing a first port of a node on a network comprising an intelligent connection system and implementing protocols permitting ports to report their own and no other port'"'"'s state or changes thereto, comprising:
-
transceiver means for providing a physical interface for the first port; and
a protocol controller means for transmitting, in response to a failed communication with the second port, a notification to the intelligent connection system indicating that the second port is the source of the notification and has experienced an internal state change. - View Dependent Claims (27, 28, 29, 30)

31. A computer-readable medium on which is embedded a program, the program performing a method advertising port state changes in a network implementing an intelligent connection system, comprising:
-
detecting, by a first port, an interruption in communication with a second port; and
transmitting form the first port to the intelligent connection system a notification of a state change in the second port, wherein the notification identifies the second port as the source of the notification. - View Dependent Claims (32, 33, 34, 35, 36)
