متن کاملA Novel Cell Scheduler with QoS Guarantee for Services in ATM Networks∗
Real-time services, including constant bit rate (CBR) and real-time variable bit rate traffic (rt-VBR), have become increasingly important owing to the rapid proliferation of multimedia applications. A cell multiplexing method capable of handling real-time traffic should satisfy related quality of service (QoS) requirements, including cell transfer delay (CTD), cell delay variation (CDV) and ce...
متن کاملPredictive shaping for VBR MPEG video traffic transmission over ATM networks
The use of smoothing techniques to remove the periodic fluctuations of the bit rate generated by the codification modes of the MPEG algorithm is very suitable in video transmission. In this way, the multiplexing gain is maximized and the resource allocation is reduced in ATM Networks. The traffic smoothing can be achieved storing the cells in a buffer. This buffer is allocated between the coder...
متن کاملFuzzy shaper versus leaky bucket shaper in Voice over Internet
Nowadays, is more and more usual to implement the voice service over Internet (VoIP), due to the reduction in price both for the network operator and for the final users. In this paper, it is presented a new traffic shaper that increases the number of stablished connections and minimizes the delay time in the case of using an IP/ADSL (Internet Protocol/Asymmetric Digital Subscriber Line) enviro...
متن کاملThe Generic Cell Rate Algorithm ( GCRA ) 7 3 Leaky Bucket Admission Schemes
The ATM Forum has recently defined a new data service called Guaranteed Frame Rate (GFR) Service. This new service aims to support minimum bandwidth guarantee for a VC and allows any excess bandwidth in the network to be shared among the contending VCs in a fair manner. It was proposed that the service requirement of GFR may be supported using the Generic Cell Rate Algorithm (GCRA), or equivale...
