Document Type and Number:
Japanese Patent JP2540950
Kind Code:
B2
Abstract:
PURPOSE:To attain optimum re-routing by sending back an end packet including a fault logical channel number desired of recovery to a 2nd node through a fault bypass and bypassing a written fault logical channel to the fault bypass so as to form the fault bypass circuits sequentially. CONSTITUTION:An A-1 positive ACK 832 is sent to a channel 909 and in the case of the priority of fault channels as channel 906>channel 907>channel 908, an A-1 return packet reception channel and a fault channel 906 are connected and an A-1 end packet 931 added with a connected fault channel ID 906 is sent to the channel 909. Upon the receipt of a B-1 return packet 833, a node (3) 903 sends a B-1 positive ACK 836 to a channel 910 to connect a B-1 return packet reception channel and a fault channel 918 and sends a B-1 end packet 932 added with 1 connected fault channel 918 to the channel 910. Thus, a route for bypasses for faulty lines is established.
