Abstract:
1. A method implemented by a network device located at a first access site of an optical transport network, the method comprising: establishing, by the network device, a first Ethernet link aggregation group (LAG) at the first access site; establishing, by the network device, a second Ethernet LAG at the first access site; creating, by the network device, a first optical channel (OCh) LAG subpath from the first Ethernet LAG, via a second access site of the optical transport network, to an Ethernet LAG at a third access site of the optical transport network; creating, by the network device, a second OCh LAG subpath from the first Ethernet LAG, via a distribution site of the optical transport network, to the Ethernet LAG at the third access site; creating, by the network device, a first optical data unit (ODUk) LAG subpath from the second Ethernet LAG to an Ethernet LAG at the second access site; and creating, by the network device, a second ODUk LAG subpath from the second Ethernet LAG, via the distribution site and the third access site, to the Ethernet LAG at the second access site.
