Adaptive Virtual Buffer(AVB)-An Active Queue Management Scheme for Internet Quality of Service
نویسندگان
چکیده
In this paper we present a virtual queue based active queue management scheme called Adaptive Virtual Buffer(AVB). We study its properties in satisfying the QoS requirement such as low packet loss rate and high throughput; its ability in maintaining stable queue length under various network configurations such as the number of connections and round trip delay; and its robustness in the presence of extremely short flows. Using a mathematical tool based on control theory, we present a simple rule in choosing the parameters for this algorithm. Through extensive simulations, we validate our design and compare the performance with some other AQM schemes such as RED, REM and AVQ.

In this paper, loss probabilities and steady state probabilities of data packets for an asynchronous transfer mode (ATM) network are investigated under the buffer division and push-out schemes. Data packets are classified in classes k which arrive in Poisson fashion to the service facility and are served with general service rate under buffer division scheme, finite buffer space N is divided in...
متن کاملA New Algorithm for Controlling a Buffer with Time-Varying Arrival Rate
Due to the increase in network services including real-time video and audio applications, Quality of Service (QoS) became a crucial issue for today’s Internet users. In order to guarantee QoS to diverse Internet services, it is important to employ effective buffer management schemes at Internet routers. Effectively constraining the mean queue length to a specified level is a key QoS requirement...
متن کاملA Parallel Virtual Queue Structure for Active Queue Management
The Adaptive RED proposed by Feng et al . [5] is shown to have small packet delay and queue length variation for long-life TCP traffic such as FTP connection with a large file size. However, a great portion of Internet traffic is shortlife web and UDP traffic. Most web traffic has a small file size and its TCP session is mainly operated in the slow start phase with a small congestion window siz...

Rapid development of telecommunication technologies and the ever growing network users demands have made network congestion a prominent problem in today’s Internet. Congestion not only brings significant performance degradation to the network, but also hurts the Quality-of-Service (QoS) that the users receive and even raises up some security concerns such as Denial-of-Service (DoS) attacks. The...
متن کاملAn Efficient Packet Discarding Scheme for On-demand Video Streaming
Streaming services over the Internet are expected to grow rapidly in the near future. However, bursty packet losses caused by buffer overflow at routers are a serious problem in these services, and are responsible for degradation of the Quality of Service (QoS). Active Queue Management (AQM) that discards the packets at routers is effective for avoiding the buffer overflow but results in the de...
