چکیده

We propose a minimum cost method for traffic shaping and policing in the context of quality-of-service (QoS) based networks. Given the user's desired QoS and the network's resource availability, our procedure determines the least-cost parameters for a traffic shaper or policer which still guarantees access to the network whilst satisfying the QoS constraints. We illustrate our scheme using on-off sources and formulate the QoS constraints by effective bandwidths.

Performance Evaluation of Connection Admission Control for IEEE 802.16 Networks

Quality of Service (QoS) provisioning to the various kinds of network traffic is one of the major design criteria of IEEE 802.16 WiMAX standard. The MAC and physical layers of 802.16 standards are designed to support different types of real time application by providing QoS. Scheduling, Connection Admission Control (CAC) and traffic policing are the major issues to ensure QoS. In standard, sche...

Buffered and Unbuffered Leaky Bucket Policing: Guaranteeing QoS, Design and Admission Control

Traffic shaping and smoothing using buffers or leaky buckets does not necessarily improve Quality of Service (QoS). In fact there is a trade-off between controlling user traffic and guaranteeing QoS to the users. We consider the first two stages (source node and border node before entering a network cloud) of an end-to-end QoS problem and assume that the QoS requirements across each of the two ...

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

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 ...

Providing Conformance of the Negotiated QoS using Traffic Conditioning for Heterogeneous Services in WCDMA Radio Access Networks

In order to provide negotiated QoS to the end users in next generation mobile networks, a traffic conditioner may be deployed to provide conformance of a service agreement. The traffic conditioning is performed by traffic shaping or/and policing. A framework of applying traffic conditioning in radio access network is proposed in this paper. The main idea of our traffic conditioning approach is ...

A Framework for Bandwidth Management in ATM NetworksŠAggregate Equivalent Bandwidth Estimation Appro - Networking, IEEE/ACM Transactions on

A unified framework for traffic control and bandwidth management in ATM networks is proposed. It bridges algorithms for real-time and data services. The central concept of this framework is adaptive connection admission. It employs an estimation of the aggregate equivalent bandwidth required by connections carried in each output port of the ATM switches. The estimation process takes into accoun...
