<p>PURPOSE:To increase the number of understood packets in a packet switching network by deciding an enquiry request whether packets can be transmitted or not in consideration of the number of packet repeaters or the number of packet repeating links. CONSTITUTION:Before transmitting a packet signal from a packet switching station PX1 to a packet switching station PX2, the propriety of transmission is enquired to the switching station PX2. After receiving the enquiry, a central control unit CC2 in the switching station PX2 discriminates whether the number of packet repeating stations from the switching station PX1 to the station PX2 or the number of packet repeating links exceeds a fixed value or not when the network is of a fixed congested status, decides the propriety of packet transmission from the discriminated result and returns the result to the switching station PX1. When the returned result shows the approval of transmission, packets can be transmitted from the switching station PX1.</p> |
