Title: Transmission right control system for ring shape transmission system
Inventor: FUKUMOTO KAZUYUKI
IPC: H04L12/42
Filed: 1992-02-04
Abstract: PURPOSE:To prevent a bias for obtaining the right of transmission by obtaining the right of transmission in order of registration, when transmission requests of plural nodes are duplicated. CONSTITUTION:A transmission right acquisition deciding part 11 monitors a frame of a cyclic transmission signal, and obtains the right of transmission, in the case a field A of the frame is in a free state, and also, there is no waiting of the right of transmission of a frame B, or in the case the field A of the frame is in a free state, and also, a transmission right request of the own node is in the head of a transmission right queue of the field B. When the right of transmission is obtained, the transmission right obtaining part 11 instructs a transmission start to a transmitting part, and simultaneously, informs a transmission right obtaining success to a transmission right requesting part 12. Subsequently, the transmission right requesting part 12 erases the transmission right request waiting registration of the own node being in the head of the field B, puts close all request displays waiting after the own node to the front, moves the node which requests the right of transmission subsequently to the own node to the head of the queue, and the right of transmission is transferred to other node after the right of transmission of the own node is renounced.
