Performance of TCP/IP over ATM over an ADSL
نویسندگان
چکیده
The performance of TCP/IP over ATM over an asymmetric digital subscriber line (ADSL) was investigated. Because the bandwidth of an ADSL link can vary over time due to changes in the link’s physical conditions, which degrades TCP performance, we performed simulations for various ATM traffic controls, including available bit rate (ABR) and generic flow control, used to handle variations in the ADSL bandwidth. This analysis showed that using an ABR control is effective under various traffic conditions. An ABR switch algorithm that can achieve good performance under any condition was investigated. key words: ADSL, ATM, TCP, bandwidth variations, ABR,

Characterization of performance of TCP/IP over PPP and ATM over asymmetric links
The objective of this paper is to characterize and analyze the performance of TCP/IP when used over point-to-point protocol (PPP) and asynchronous transfer mode (ATM) over asymmetric links. This will allow us to gain insight into this new protocol architecture used in the asymmetric digital subscriber line (ADSL) access network and investigate the related quality of service (QoS) issues. Using ...
متن کاملModelling ADSL with IP and ATM Performance Study
This paper describes ADSL (Asymmetric Digital Subscriber Line) simulation model developed using COMNET III. ADSL is integrated with IP (Internet Protocol) and ATM (Asynchronous Transfer Mode) in order to provide QoS (Quality of Service). Using this model, a comparison study between networks using IP over ATM over ADSL and IP over ADSL is provided.
متن کاملTcp/ip over Atm - Performance Evaluation and Optimisation
The integration of TCP/IP and ATM is a challenging architectural issue in today’s global networks, where the unique properties of ATM technology can be combined with the TCP/IP mature and well-proven protocol suite. A rigorous characterisation of the performance of TCP/IP over ATM can be a powerful tool for the efficient use of both technologies. TCP error and flow control mechanisms were desig...
