A method for implementing the member deletion by the sink side of LCAS and the sink side status machine thereof

摘要

The present invention relates to a deleting member method by LCAS originating from sink source.Said method includes 1, sink transmitting MST=FAIL of member o be deleted and transiting its state into REMOVE, wherein said REMOVE state being sink state machine pre-increased state, to express in said state said sink member waiting delete confirming and still needing extracting service from the member to be deleted, 2, sink received said MST=FAIL, transmitting control field CTRL=DNU, to make said to deleted member state transiting DNU from NORMAL, 3, after sink receiving to be deleted member control field CTRL=DNU, stopping extracting service from said member at next multi-frame, 4, transiting said to be deleted member state into IDLE, which means delete successful.
