Generalized service protection systems and methods

摘要

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.

1. A node, comprising:
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; wherein the data channel and the management channel are separated into different service identifier name spaces with a service identifier for the management channel being a different type from the arbitrary service identifier for the data channel, wherein G.8032 protection is provided on the data channel using the arbitrary service identifier, wherein the arbitrary service identifier is a non-Virtual Local Area Network (VLAN) Identifier for blocking and unblocking on the data channel using the G.8032 protection.
