Title:
通信装置および優先制御方法
Document Type and Number:
Japanese Patent JP5759941
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve problems in a prior art technique about which in software processing, when the number of users increases, it requires a CPU used exclusively for WFQ which can be processed at high speed by DSP and the like in software processing, and in hardware processing, when user flows to be processed increase, tables to be stored increase, and it must be efficiently implemented in hardware.SOLUTION: In order to perform efficient WFQ processing, a band control queue management table has information on a weighted sequence number, and a write-in side or read-out side calculates the weighted sequence number of a frame, and stores it in a frame reception buffer. The read-out side determines read-out order in accordance with the weighted sequence number.
