Method for operating an optical transport network node

摘要

It is proposed a method for operating an optical transport network node of an optical transport network to provide Shared Mesh Protection on an optical data unit level or to provide m:n linear protection on an optical data unit level. An analysis means (2) determines a memory address (4) of pre-calculated configuration data (6) residing on a memory (8) of the optical transport network node. A transmission means (10) of the optical transport network node is reconfigured with the pre-calculated configuration data (6) at the memory address (4) such that a normal traffic signal is transported via a protection transport entity.
