Excerpt
Excerpt 13. A method of maintaining a virtual connection between a client and a gateway across multiple physical connections in a computing environment capable of having a connection to a network, said method comprising the steps of:
establishing a first physical connection from said client to said gateway using a first of at least one available connection media and a first of at least one available connection device;
establishing a second physical connection from said client to said gateway using a second of said connection media and a second of said connection devices, wherein at least one of said second medium and said second connection device is different from said first medium and said first connection device; and
maintaining a logical connection between said client and said gateway, wherein said logical connection is initially supported by said first physical connection and then by said second physical connection.
14. The method for maintaining a virtual connection between a client and a gateway across multiple physical connections according to claim 13, wherein said maintaining a logical connection step further comprises:
sending a session key from said client to said gateway using said second physical connection, wherein said session key identifies said logical connection and was created when using said first physical connection; and
receiving said session key in said gateway, and detecting said receipt as a request to continue said logical connection.
16. The method for maintaining a virtual connection between a client and a gateway across multiple physical connections according to claim 14, wherein said second physical connection is established in response to a disruption or failure of said first physical connection.
