Abstract
Systems and methods for ring protection switching in a network based on selectively blocking and unblocking a port include forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop; and selectively blocking and unblocking traffic on the port to provide the ring protection switching over the closed loop, wherein the selectively blocking and unblocking is performed based on a management channel that utilizes a second service identifier that is a different type from the first service identifier.
Claims20
A method for ring protection switching in a network based on selectively blocking and unblocking a port, the method comprising:
- forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop;
- operating a management channel that utilizes a second service identifier that is a different type from the first service identifier;
- and
- selectively blocking and unblocking traffic including both the data channel and the management channel on the port to provide the ring protection switching over the closed loop based on the management channel such that G.8032 protection is performed on the data channel that is one of, for the closed loop, Optical Transport Network (OTN) traffic, Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) traffic, Multiprotocol Label Switching (MPLS) traffic, and Internet Protocol (IP) traffic.
An apparatus configured to perform ring protection switching in a network based on selectively blocking and unblocking a port, the node comprising:
- circuitry adapted to forward traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop;
- circuitry adapted to operate a management channel that utilizes a second service identifier that is a different type from the first service identifier;
- and
- circuitry adapted to selectively block and unblock traffic including both the data channel and the management channel on the port to provide the ring protection switching over the closed loop based on the management channel such that G.8032 protection is performed on the data channel that is one of, for the closed loop, Optical Transport Network (OTN) traffic, Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) traffic, Multiprotocol Label Switching (MPLS) traffic, and Internet Protocol (IP) traffic.
A node configured to perform ring protection switching in a network based on selectively blocking and unblocking a port, the node comprising:
- at least one port adapted to forward traffic over a data channel that utilizes a first service identifier and adapted to operate a management channel that utilizes a second service identifier that is a different type from the first service identifier, wherein the data channel is routed in the network along a closed loop;
- and
- a device adapted to selectively block and unblock traffic including both the data channel and the management channel on the port to provide the ring protection switching over the closed loop based on the management channel such that G.8032 protection is performed on the data channel that is one of, for the closed loop, Optical Transport Network (OTN) traffic, Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) traffic, Multiprotocol Label Switching (MPLS) traffic, and Internet Protocol (IP) traffic.
