    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: A flexible mapping method to map a Physical Coding Sublayer (PCS) structure from Flexible Ethernet and/or Multi Link Gearbox (MLG) to Optical Transport Network (OTN), includes receiving one or more Virtual Lanes; and mapping each of the one or more Virtual Lanes into a Tributary Slot, wherein a rate and number of the Tributary Slot(s) in OTN is set based on a rate and number of the one or more Virtual Lanes. A transport system and a flexible de-mapping method are also described. The systems and methods map the generalized MLG-style group of lanes (virtual PHYs/PMDs) into an OPUflex Tributary Slot (TS) structure, keeping PCS structures intact, and creates a single ODUflex container with a matching rate of FlexE for end-to-end flow.
