Switching apparatus for supporting protection switch-over mode of SONET/SDH network and method thereof

摘要

An integrated switching apparatus for supporting a protection switch-over mode of a circuit-switched network and a method thereof are disclosed. The integrated switching apparatus includes: a plurality of input circuit data processing unit for converting externally received circuit data to fixed length packets; a plurality of input packet data processing unit for converting externally received packet data to fixed length packets; a fixed length packet switching unit for switching the fixed length packets to a destination output port; a plurality of output circuit data processing unit for restoring and outputting circuit data by converting the fixed length packets according to a protection switch-over mode; a plurality of output packet data processing unit for restoring and outputting the fixed packet transferred from the fixed length packet switching unit according to a protection switch-over mode; and a control/timing unit for collecting state information and distributing the collected state information.
