ABSTRACT:
A method and apparatus for performing packet synchronized switch-over is disclosed. The present invention eliminates packet loss by preventing frame integrity from being broken. Switch-over requests soliciting a change from a first virtual channel link to a second virtual channel link are received. After the receipt of a switch-over request, state information for identifying the occurrence of a frame completed state is monitored. The switch-over from the first virtual channel link to the second virtual channel link is performed when the frame completed state occurs. The frame completed state is detected by determining whether a current cell being received has an AUU set. The invention eliminates packet loss by maintaining layer frame integrity for both ingress and egress switch-over requests.
