摘要: An Optical channel Data Unit flex (ODUflex) resizing method, node, and network include determining that the ODUflex needs resizing, wherein the ODUflex is configured in the network on a current path between the node and a second node in the network; when the resizing is a decrease, reducing a size of the ODUflex by i) a resize decrease operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation; and, when the resizing is an increase, increasing a size of the ODUflex by i) a resize increase operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation. The method provides hitless resizing without using ITU Recommendation G.7044/Y.1347 (10/11) and can perform the reducing or the increasing changing bandwidth of the ODUflex by approximately 100 G in less than a second.

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.
