Mapping the quality of service over heterogeneous networks: a proposal about architectures and bandwidth allocation
نویسندگان
چکیده
The paper presents a general framework and some possible architectures to get a feasible QoS (Quality of Service) mapping among network portions that use different technologies to provide a fixed service level to the terminal users. In general, there is a strong need to have “communication” among portions implementing different QoS technologies: a proper architecture, functionalities and protocols should be defined. The current work, after stating the framework, tries to propose some architectural solutions and shows a preliminary performance investigation concerning mapping of a specific QoS parameter as bit loss among an ATM and an IP portion. Keywords-QoS Technologies; QoS Relay Entities; QoS Mapping; Equivalent Bandwidth.

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...
متن کاملJointly power and bandwidth allocation for a heterogeneous satellite network
Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
