Claim Text:
1. A method of managing a connection path failure, wherein a first cloud computing data center and a second cloud computing data center are connected through a provider backbone bridge network (PBBN), the method comprising: forming a first plurality of working connection paths and protection connection paths, through the PBBN, between an end point of the first cloud computing data center and an end point of the second cloud computing data center; forming a second plurality of working connection paths and protection connection paths between end points within one of the first and second cloud computing data center; exchanging a test message between the end points of the first cloud computing data center and the second cloud computing data center that are connected to a first working connection path among the first plurality of working connection paths and protection connection paths; determining that a failure has occurred at the first working connection path when the test message is not received at one of the end points connected to the first working connection path; and switching the first working connection path in which the failure has occurred to a first protection connection path among the first plurality of working connection paths and protection connection paths, wherein each of the first data center and second data center comprises a provider bridge (PB) device that is connected to the PBBN and a switch that is connected to a plurality of servers comprising a plurality of virtual machines (VM), and wherein the forming of the first plurality of working connection paths and protection connection paths between the end points of the first cloud computing data center and the second cloud computing data center comprises forming a connection path based on a first virtual local access network (VLAN) between the VM and the switch, a second VLAN of the PB device, and a third VLAN and a backbone service instance ID (I-SID) of a provider edge bridge (PEB) and a provider core bridge (PCB) included in the PBBN, wherein the connection path is one of at least one working connection path and at least one protection connection path between the end points of the first cloud computing data center and the second cloud computing data center.
