  • Method to establish a non-disruptive communications path between multiple devices
    Patent number: 10069763
    Abstract: A method for establishing a communications path is provided. A routing path between a source port on a source switch and a destination port on a destination switch through intermediate switches is identified. A first message is sent to the source switch, the destination switch and the intermediate switches instructing the recipient switches to prepare for establishing a connection. In response to receiving a first set of acknowledgment messages from the recipient switches, a second message is sent to the destination switch and the intermediate switches instructing these switches to establish a connection to the destination port along the identified routing path. In response to receiving a second set of acknowledgment messages from the destination switch and each of the intermediate switches, a third message is sent to the source switch instructing it to establish a connection between the source port and the established connection to the destination port.
