TUNNELED WINDOW CONNECTION FOR PROGRAMMED INPUT OUTPUT TRANSFERS OVER A SWITCH FABRIC

摘要

Tunneled window connections are utilized in a switch fabric to perform programmed input output transfers. The window connections are based on global IDs. A management entity may enforce the tunneled window connections, improving security.

1. A method of performing a programmed input output (PIO) transfer in a switch fabric, comprising:
defining visibility of at least one host end point to other host end points of a switch or switch fabric, including defining windows on these host end points and connections between them; and tunneling PIO transfers between connected windows by routing PIO transfer between window segments of host end points based on a global ID.
