Abstract
A node includes a first port configured to be selectively blocked and unblocked; a second port configured to be selectively blocked and unblocked; a forwarder between the first port and the second port; a management channel between the first port and the second port, wherein the selective blocking and unblocking of the first port and the second port is based on the management channel; and a data channel between the first port and the second port, wherein the data channel utilizes an arbitrary service identifier. A method can include operating a ring with Ring Protection Switching comprising a forwarding mechanism and a blocking mechanism that are independent and decoupled entities therebetween, wherein the ring includes a management channel and a data channel that each utilize an arbitrary service identifier.
