Fair and Delay Adaptive Scheduler (FDAS) is a scheduling mechanism that dynamically adapts to the incoming traffic flows' requirements in term of bandwidth allocation, delay bounds and packet loss restrictions. It performs this utilizing both virtual finish time fluid scheduling along with schedulability and delay sensitive scheduling. The former ensures that the flows receive a fair share of the...
Several objectives are aimed when scheduling traffic for transmission on heterogeneous networks. Traffic flows might belong and required to satisfy different set of requirements for a diverse set of applications, end users and networks. Schedulers have several goals to achieve in order to meet the needs of all stakeholders involved. Some schedulers are built to ensure fairness in bandwidth allocation,...
The key feature of Unified Communications (UC) lies in its ability to provide the service that the customer wants, when he wants and regardless of the device being used. At the heart of the UC architecture, which spans different layers from application layer to network, comes the Quality of Service (QoS) framework that is essential to provide adequate service to different communication session's call...
Unified communications (UC) offers users an uninterrupted communication service regardless of the device which the user is using, the heterogeneous networks to which he might be connected, the physical and logical context in which he exists and the diversity of QoS requirements by different session participants and services. Providing and maintaining an acceptable level of QoS, as perceived by all...
