LINEAR relay devices, systems workarounds TDM LINE AND METHOD OF ADMINISTRATION detour TDM LINE

摘要

1. Linear relay apparatus for relaying data through a communication line, wherein the device forms a ring network, where the linear relay apparatus and an opposite apparatus connected in a ring via a hardware-connecting line with a variable transmission rate, wherein the transmission rate is changed, the detection bandwidth reduction transmission suitable for transmission caused by the change in the transmission line connecting hardware with variable rate preliminary speed to set as a TDM line transmission path, the linear relay apparatus creates a chimney TDM line, allowing the transmission volume exceeding TDM bandwidth lines from hardware-connecting line with a variable transmission rate through the bypass path through another linear relay apparatus connected in a ring in accordance with the degree of change peredachi.2 speed. Linear relay apparatus according to Claim. 1, wherein when creating the bypass path TDM lines, line relay apparatus creates a chimney TDM line to line in the relay apparatus as a destination of the transmission destination by the transmission request redirection information indicating the amount of excess width TDM bandwidth line of hardware-connecting line with a variable transmission rate and a destination address indicating the linear relay apparatus as the destination Dest Nia TDM data transmission line to another linear relay apparatus connected in a ring, and thereby re
