    摘要: An Optical Transport Network (OTN) method, an OTN switching node method, and an OTN node utilize a “double wrapper” configuration to eliminate clock transients in OTN networks. That is, the systems and methods bury an ODU beneath another overclocked ODU thereby eliminating any interruptions due to clock transients, framing events or other disruptions. For example, an ODU2 can be mapped into an ODU2e, an ODU3 can be mapped into an ODU3e2, an ODU4 can be mapped into an ODUG or some other overclocked variant of ODU4, and the like. Specifically, ODU2e, ODU3e2, ODUG, etc. are overclocked variants of ODU2, ODU3, ODU4, etc. The systems and methods propose to use these overclocked signals to carry standard ODU signals to eliminate clock transient problems.

    摘要: An Optical Transport Network (OTN) transient management method, OTN node, and OTN network includes operating an OTN connection in a first mode in a network, the OTN connection traverses at least two nodes in the network, requesting a change in the OTN connection to a second mode which will cause a network transient, the change includes a timing change on the OTN connection affecting the at least two nodes, and performing transient management at the at least two nodes to mitigate the network transient, the transient management prevents spurious alarms due to the change between the first mode and the second mode.
