Service Provisioning in an ATM-over-ADSL Access Network
Asymmetric Digital Subscriber Loop (ADSL) technology is a new platform for delivering broadband services to homes and small businesses, thus bringing the information highway to the mass market. Successful deployment of an ADSL-based access network is not only a matter of delivering faster rates, but also offering solutions that are cost-effective and easy to use and to manage. As deregulation a...
متن کاملATM over ADSL: The “Best-Effort” PVC Provisioning for ATM Call Flow
Asymmetric digital subscriber line (ADSL) is the latest copper-wire access technology that has the capability to deliver data rate up to 8 Mbps in downstream and up to 640 kbps in upstream. The ADSL Forum has also defined the model for ADSL/ATM connections. ADSL can be connected to ATM core network through the access network called digital subscriber line access multiplexer (DSLAM). This paper ...
متن کاملBandwidth provisioning in ADSL access networks
We consider an ADSL access network consisting of subscribers, DSLAMs, metro Ethernet switches and a broadband remote access aggregation server (BRAS). We obtain expressions for dimensioning the access network in the upstream direction. Specifically, we show that the bandwidth required at each DSLAM, metro Ethernet switch, and BRAS can be expressed as an exponential function of the subscribers i...
متن کاملPerformance of TCP/IP over ATM over an ADSL
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 AD...
متن کاملVideo retrieval service over an ATM access network under IPv6/RSVP protocols
There is a growing pressure raised by Internet users to extend the basic best-effort IP network architecture to support QoS. At the same time there is need to increase accessibility of the IP service for residential users. Network designers, vendors of network products and application developers are cooperating in order to evaluate possible migration paths to meet the demand. This paper describ...
