VIRTUAL LANE IDENTIFICATION METHOD AND APPARATUS FOR APPLYING VIRTUAL LANE SCHEME TO OPTICAL TRANSPORT NETWORK

摘要

There is provided a virtual lane identification method and apparatus for applying a virtual lane scheme to an optical transport network. More particularly, there is provided a technique for identifying virtual lanes using multi-frame alignment signals (MFASs) at a receiver without modifying an existing frame structure of an optical transport network signal by periodically changing a rotating direction of the virtual lanes when applying an Ethernet virtual lane scheme to a ultra-high speed OTN signal, particularly to OTU4 (100G).
