چکیده

This paper describes the architecture of an ATM scheduler that performs cell spacing and respects additional time constraints. The scalable timing mechanism allows for real-time execution even in presence of many ATM virtual channel connections. The algorithm is suited as reference for special purpose implementations and the core idea can be adapted for scheduling problems in IP networks. In particular, a scheduling algorithm for an AAL2/ATM multiplexing device is presented.

Decision Point of AAL2 Multiplexing for Voice and Data Services in 3G WCDMA Network

To predict AAL2 multiplexing performance, we derived bandwidth gain analytically using discrete Markov chain model for voice service and validated these results with a simulation. And we also performed detailed simulation for voice and data services in a concentrator. Based on the analysis, we find that there is no major benefit of AAL2 multiplexing in a concentrator. The benefit of AAL2 multip...

Performance analysis of AAL2/ATM in UMTS radio access network

The focus of this paper is the performance of ATM/AAL2 as a transport technology for Universal Terrestrial Radio Access Network (UTRAN) in UMTS/IMT-2000 setting. In this work, we propose an analytical model for the transparent multiplexing and transport through UTRAN of several voice channels onto a single AAL2/ATM VC. We investigate the queue building up at the AAL2 multiplexer in order to der...

Performance Evaluation of an AAL2 Link Transmission Scheme for Voice and Data Packets in BS-BSC Links

An AAL2 link transmission scheme is considered as a promising bandwidth-efficient voice/data transmission method in BS-BSC links of third generation radio access networks. To guarantee low delay requirement of voice traffic, voice delay restriction methods are introduced in the AAL2 link transmission scheme. That is, a timer is used in the loading of voice ATM cell payload for limiting cell pac...

An Analytical Model to Compare AAL2 with a Prebuffered TDM-Based Multiplexing System to Support VBR Voice Connections over ATM

Despite the spread of multimedia applications, voice will still account for most of the overall traffic in telecommunications networks in the near future, as it did in the past. For this kind of traffic it has been observed that if one ATM VCC is assigned to only one source, too high delays to fill the whole 48-byte ATM-cell payload, or high bandwidth wastes if an ATM cell is partially assigned...

Performance Analysis of AAL2 switching/multiplexing in the Iub interface in UMTS Network

User-perceived application-level performance is very important in the adoption and success of UMTS (Universal Mobile Telecommunication System) services and infrastructure. To predict this performance, a detailed end-to-end UMTS network performance simulator was developed. The simulator allows the modeling of application traffic characteristics, network architecture, network elements, and protoc...
