摘要:
In a path status monitoring method and device which can enhance or reduce a band more rapidly, for example, SONET frames FR serially connected over 32 frames to which frame Nos. FN (“0”-“31”)) are assigned are cyclically generated respectively for paths P0-P2 in a cycle TC (=64 ms). After output timing delays TD0-TD2 of the frames FR are shifted by an optimal delay interval D (=21 ms) between the paths P0-P2 based on the number of the paths “3”, the output timing delays TD1 and TD2 are restored by preliminarily obtained transmission delays for the paths P1 and P2 to the path P0. When the frames FR are transmitted through each of the paths P0-P2, statuses (path statuses MST) where a reception fault has occurred in each of the paths P0-P2 are collected to be stored in the frame whose frame No. FN=“0”.

摘要:
A redundancy control method is disclosed that controls a first redundancy function that switches between a working line and a protection line in response to a detection of a line error and a second redundancy function that performs a path switching in response to a detection of a path error in a ring network operating at a path rate lower than a line rate thereof. The method comprises a step of masking the path error detection within a period from a time of the detection of the line error to an expected time of the detection of the path error.

摘要:
In an apparatus for accommodating and multiplexing asynchronous client signals in which an idle signal is defined, the transmission side transmits client signals after synchronizing the client signals by inserting or removing, with reference to a specific client signal, an idle signal to/from the same type of another client signal, and in the receiving side, a PLL part is shared by recovering a clock from a client signal and distributing the clock for another client signal.
摘要:
The present invention discloses a method for controlling a physical bandwidth of a ring-based network by employing a ring application of a data link layer that operates in a physical layer. The method includes the steps of a) requesting each of a plurality of node apparatuses included in the ring-based network to confirm whether the bandwidth can be changed, b) instructing each node of the apparatuses to prepare for the bandwidth change upon receiving a confirmation that the bandwidth can be changed, c) reporting that the preparation for the bandwidth change is completed, and d) changing the bandwidth by using a bandwidth changing function of the ring application upon receiving the report of the completion of the preparation for the bandwidth change.
摘要:
When an externally received data frame is transmitted at a station of a ring-shaped packet communication network, a congestion point in the communication network is defined as a boundary point, a frame addressed to a station located before the boundary point is transmitted at a first transfer rate, and a frame addressed to a station located after the boundary point is transmitted at a second transfer rate lower than the first transfer rate.
