The Research of Acceptance and Scheduling Scheme Based on the Overall Network QoS

摘要

Many factors affect the QoS of network, and the congestion control mechanism is the most important one. In many references, the research on QoS is focused on the specific network architecture, while the QoS of overall network is still relatively seldom studied. In the paper, an acceptance and scheduling scheme based on the overall network QoS (ASSoQoS) proposed is a new acceptance and scheduling algorithm of the link traffic. At first, the data stream with the admission control strategy will be distributed in different weights , the data flow will get the link (with different weight) transmission scheduling to improve the overall network QoS , according to the allocated weight of a network link and status by real-time network monitoring.
