End-to-end QoS can be achieved through resource reservations along the communication path between end points. Per flow or per aggregate signaling can be used to set up reservation states in routers or domains on the path. In a mobile environment this reservation process can be very cumbersome, given that (i) the time to set up the resources in the new path is not neglectable and (ii) the resources...
This paper presents an approach that aims to provide quality of services (QoS) over heterogeneous Internet domains. The goal is to install and to manage QoS inside each domain and to ensure it on the end to end data path. QoS is a key requirement representing a significant infrastructure upgrade for future networks. Our proposal relies on the multi-service, multi-technology model based on Bandwidth...
The IST European project EuQoS ("end-to-end QoS over heterogeneous networks ") has defined a NGN architecture that builds, uses and manages the end-to-end QoS path across different administrative domains and heterogeneous networks (UMTS, xDSL, Ethernet, WiFi and satellite access networks and IP/MPLS domains). The architecture follows a model more similar to Internet open architecture than...
This paper deals with the problem of providing quality of service (QoS) in heterogeneous networks. It proposes an approach that is able to build a generic signalling control protocol to offer a guaranteed QoS in a set of heterogeneous Internet domains. The given protocol manages during the admission control phase the end-to-end requests of the QoS connections with respect to their QoS requirements...
