“…A number of projects that have proposed business related scenarios for delivery of video-on-demand service over QoS enabled IP networks [26]- [28]. Within these projects, the concept of wholesale bandwidth is used to describe the arrangement where the service provider leases QoS guaranteed bandwidth from the network operator, an arrangement governed via an agreed Service Level Agreement (SLA).…”

Abstract-The paper presents an admission approach for IPTV service providers that is designed to minimize QoS violations whilst effectively utilizing available bandwidth. Central to the approach is an empirical method of estimating the effective bandwidth required to satisfy QoS targets for admitted traffic flows. The paper describes this method and specifies two admission control algorithms based on the use of effective bandwidth estimates. The first algorithm employs a simple evaluation of whether there is sufficient bandwidth available to ensure, with an appropriate degree of confidence, that QoS targets will not be violated if a requested flow is admitted. The second algorithm utilizes information relating to the cost, duration and request frequency of specific IPTV content to prioritize higher revenue flows within the admission control process. Results of a simulation study (employing real traffic traces of long-lived flows) indicate that the proposed algorithms ensure that an adequate, but not overly generous, amount of bandwidth is allocated to ensure that QoS targets for accepted flows are met. Furthermore, they demonstrate the potential advantage of using content specific information in the admission control process to maximize generated revenue.Index Terms-Admission control, aggregated traffic, effective bandwidth, quality of service.

“…This was due to the general acceptance of Ethernet in private networks, the efficient multiplexing capabilities of Metro Ethernet, an attractive price setting of optical Ethernet interfaces, and the efficient reuse of know-how and components from the large LAN (Local Area Network) market. The challenge for MUSE was to provide secure and scalable multi-service and multi-provider capabilities in such an Ethernet based access network [2]. MUSE defined two forwarding models for the access network architecture: Model 1 is based on L2 (Layer 2) Ethernet forwarding and Model 2 on L3 IP (Internet Protocol) forwarding [3].…”

“…Recently, different architectures for passive optical networks (PON) have been proposed 1 to increase the aggregate bandwidth and the total number of subscribers. A key technology to achieve this goal is the use of wavelength division multiplexing (WDM) together with multiple access techniques per wavelength, including orthogonal frequency division multiplexing (OFDM), subcarrier multiplexing (SCM), or time division multiplexing (TDM).…”
