Embodiment Construction

[0038] The implementation of the system and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Figure 5 It is a system structure diagram with 4 classification queues of the present invention. Such as Figure 5 As shown, the system is composed of a scheduler 501 , a classifier 502 , a timer 503 , a parameter input interface 504 and a queue pool 505 . Wherein the timer 503 inputs timing clocks of two cycles to the scheduler 501, the timing clock of one cycle is a slice timing clock with a small granularity (smaller cycle), and the timing clock of another cycle is a scheduling cycle timing clock, wherein the above timing The period of the clock is the time slice period ts, and the above-mentioned slice timing clock and the scheduling cycle timing clock are in multiples; the parameter input interface 504 inputs scheduling parameters to the scheduler 501; the queue pool 505 is...

Abstract

The system thereof comprises: a scheduler, a classifier, a timer, a parameter inputting interface and a queue pool. Wherein, the timer outputs a clock signal with two cycles to the scheduler, and the parameter inputting interface outputs the scheduling parameters to the scheduler; the queue pool is composed of n queues. In the invention, when the next cycle starts and has not scheduled the last queue yet, then after completing the process of the current packet, the scheduling procedure will return to the previous step and restart; the parameters about the scheduling cycle, time slice cycle and wideband allocation ratio can be dynamically modified; the modified parameters is enabled at the beginning of the next scheduling cycle.

Description

technical field [0001] The present invention relates to a system and method for realizing Quality of Service (Qos) at a convergence point based on classification levels. The present invention can ensure that Qos guarantees are provided for various services at the convergence point according to the bandwidth pre-allocation ratio, and the present invention Mainly used in Internet Protocol (Internet Protocol) (hereinafter referred to as IP) technology field and the third generation (the third Generation) (hereinafter referred to as 3G), Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexity) (hereinafter referred to as OFDM) and other mobile communication fields . Background technique [0002] In 3G mobile communication systems and OFDM mobile communication systems, IP is usually used as the bearer platform of the system. IP is divided into two versions, Internet Protocol Version 4 (IPV4) and Internet Protocol Version 6 (IPV6), among which IPV6 ...
