QoS provisioning using traffic shaping and policing in 3rd-generation wireless networks

چکیده
According to recently presented QoS architecture by 3GPP [1], a traffic conditioner may be deployed to provide conformance of the negotiated QoS in UMTS. The traffic conditioning is performed by traffic shaping or/and policing. A framework of traffic conditioning with QoS provisioning in 3G radio access network is proposed in this paper. The main idea of our traffic conditioning approach is to employ traffic shaping at each UE and traffic policing at the RNC. The traffic generated at each UE is regulated by a traffic shaper in the form of a token bucket, and the conformance of the traffic is policed at the RNC according to traffic policing policies. A system model based on the proposed framework is implemented. The simulation results regarding the impact of traffic shaping on packet discarding probability, the tradeoff between probability of non-compliance and shaping delay are also presented in this paper.

Local and Global QoS-aware Token Bucket Parameters Determination for Traffic Conditioning in 3rd Generation Wireless Networks
Based on the framework of employing traffic shaping at the UE and policing at the RNC, we propose a local and global QoS-aware token bucket parameter determination technique for traffic conditioning in 3G wireless networks in this paper. The local QoS-awareness is achieved by the tradeoff between the shaping delay and the out-ofprofile probability at the token bucket traffic shaper, and the glo...

Future generation wireless packet networks will support multimedia applications with diverse quality-of-service (QoS) requirements. Much of the research on scheduling algorithms has been focused on hard QoS provisioning of integrated services. Although these algorithms give hard delay bounds, their stringent requirements sacrifice the potential statistical multiplexing performance and flexibili...

متن کاملWire-speed traffic management in Ethernet switches
Price advantage & ease of provisioning of Ethemet over ATM is spurring the deployment of traditional Ethemet switches in Access Networks. Fast Ethemet (FE) and Gigabit Ethemet (GE) switches for enterprise LANs lack traffic management (TM) features making them unsuitable for widespread QoS enabled Access Networks deployment. In this paper, we present efficient hardware architectures for Ethemet ...
