Title:
イーサネットスイッチにおけるスケジューリングされたフレームの多重化方法
Document Type and Number:
Japanese Patent JP6516930
Kind Code:
B2
Abstract:
The present invention relates to a method for multiplexing data frames, in a packet-switched type network. The network comprises one or several switches having:
- a first plurality of receiving ports, receiving said data frames, and
- a second plurality of transmitting ports, for transmitting at least blocks of said data frames. Each frame includes a data field comprising information related to an index of priority for transmitting the frame. More particularly, a clock (CLK) is provided to said switches so as to apply a timestamp of reception of each frame in each receiving port, and a memory medium (MEM) is further provided so as to store transitorily each received frame along with its timestamp. The method comprises then the steps of:
a) providing a plurality of memory buffers (Buff [k]), associated to respective indexes of priority, each buffer comprising one queue of frames having a same index of priority,
b) sorting (S4) the received frames in a chosen buffer according to their index of priority,
c) in each buffer (k), sorting (S6) the frames according to their respective timestamps (TSj), for ordering the queue of frames in each buffer from the earliest received frame on top of the queue to the latest received frame at the bottom of the queue, and
d) feeding (S10) the transmitting ports with each frame or block of frame to transmit, in an order determined according to the index of priority of the frame, as well as an order of the frame or of the block of frame in the queue associated to the index of priority of the frame.
