PCT No. PCT/EP88/00482 Sec. 371 Date Oct. 31, 1990 Sec. 102(e) Date Oct. 31, 1990 PCT Filed May 28, 1988 PCT Pub. No. WO89/11764 PCT Pub. Date Nov. 30, 1989.Communication system and switching element used therein. To detect and remove partly established paths, a path release explorer packet is periodically transmitted from an outside node on established paths and each time it arrives in a node a check is made whether this node is a dead end for all directions. In the affirmative a path release packet is transmitted to a preceding node to possibly release the path to the dead end node. The switching element used in each node includes a first switching bus (TB, TM) to interconnect input ports (RX1/8) to output ports (TX1/8). One of these output ports (TX9) is connected to a second switching bus (SB) which has access to all input ports. |
